Installation price from every roofing company also includes that company’s overhead or cost of running the business. For example, an established roofing company should be fully insured. This includes adequate Liability and Worker’s Comp Insurance. If for example you get a very low bid, consider that the bidder might not be adequately insured or have no insurance at all. If that is the case and you hire such a contractor, you will be responsible for any damages or injury claims that may occur.

Introducing IB PVC Roof – the longest lasting flat roofing system.

Over the last 30 years, IB Roofs, once a small family-owned company importer and installer of German-developed PVC flat roofing systems, has become a household name in the flat roofing industry. There is a reason for IB’s success – it is the ultimate quality of their products and unparalleled customer service. IB’s original roofs from 30 years ago are still in service and performing well, and when it comes to working with customers, IB will go out of their way yo give you the product you are looking for – be it a color of the membrane, a thickness, or special application requirements.

Quality of IB Flat Roofs:

IB Roofs has not changed the formulation of their PVC membrane since its early days in the late 1970′. Today’s IB membrane is the same great proven product that they were importing from Germany 30+ years ago. IB did not try to make the product cheaper by using less expensive components and fillers. On the contrary, IB has chosen to use the more expensive non-wicking scrim to prevent the membrane from splitting in the center due to water penetration, as is often the case with cheaper TPO roofs.

At some point, there comes a time when flat roof patches stop working and it is time for a replacement.

Here we will review flat roofing cost structure and factors affecting your price, IB Roof prices in Massachusetts and surrounding states ( CT, RI, NH, ME and VT). We’ll also reveal insights into choosing your flat roofing contractor, and what you should expect to pay for your particular roof, as well as your specific roofing product choice.

Flat Roof Replacement Cost: Residential and Commercial

Our general pricing for flat roof replacement works in the following manner:

Residential flat roofs are priced at $675 per square for a simple roof, with no existing roof removal. This includes 50-mil IB Roof membrane, 1/2 inch foam insulation with 2 r-value, perimeter pressure-treated wood nailer and half-roll membrane around the roof edges for wind-uplift prevention. Roof attachment using heavy-duty screws and barbed plates, 6 inches O.C. along the perimeter and 12 inches O.C. in-field. All required roofing parts and accessories are included.

Generally, for a 1000 sq. ft. residential home, your cost should be around $6750 for an average (simple) roof. If you would like to upgrade the membrane type or add more insulation, this will slightly increase your price. Please note: For all residential installations, all IB roofing membranes come with a lifetime residential warranty, therefore there is no need to upgrade from 50 to 80-mil product, as both will perform the same in protecting your roof from the elements and will remain water-tight throughout its life and beyond.

Commercial flat roofs are priced at $600 per square for roofs over 25 squares (2500 sq. ft.) The price difference from residential roofs is due to ‘economy-of-scale’ factors and lower per-square ‘setup’ and insurance costs.

If your commercial roof is around 50 squares you can expect a $30000 price range.

Use our interactive roof price calculator to estimate the cost of you roofing project. You can choose different roof options difficulty level, and will get ‘quotes’ for an IB roof, as well as other roofing products and approximate energy-savings derived from using an IB roof.

Please Note: All prices described above are assuming an ‘average’ roofing project and may/will change depending on your roof’s condition and scope of work required. The price may change in either direction, and will be determined on a case-by-case basis.

We are a premium roofing contractor and do not compete with other roofing companies solely on price. Our roof packages are priced accordingly to the quality, warranty and customer service we provide.

IB Roof packages and prices in New England

All packages described below include roof installation in accordance with manufacturer’s specifications and state/local building codes. They also include the cost of building permits, material warranty and our labor warranty. Prices below do not include tear-off of the existing roof, as that usually varies a lot from one flat roof to another. The cost of a tear-off is determined on a case-by-case basis when we perform a roof inspection. Please refer to our Residential roofing and/or Commercial roofing sections to see the available material / color / membrane thickness options available for your particular roof.

Package 1 – 50-mil white residential IB Roof with Lifetime warranty:

Our basic and most common roof package, includes 50-mil white IB Roofing membrane with all necessary trim, flashings and accessories such as drip edge, air-vents, inside/outside corner flashings, drains, etc., and 1/2 inch fan-fold Styrofoam insulation.

Cost of this package starts at around $675 per square (100 sq. ft.) of roof area.

Package 2 – IB Traditions flat Roof – Architectural Shingles Pattern imprinted onto the membrane:

IB Traditions was created specifically for low-slope roofs with aesthetics in mind. They offer the beautiful look of architectural shingle combined with proven reliability of an IB roofing membrane to give you decades of leak-free performance and curb-appeal. IB Traditions come in three color options: Sierra Vista ( beige / brown ), Stony Ridge (grey) and Mountain Spruce (green). To maintain a consistent shingles look, all IB Traditions installation feature hand-welding of all seams, and use special accessories / flashings designed to match the aesthetics of IB Traditions.

Package 3 – 80-mil white residential IB Roof with a Lifetime warranty:

Includes 80-mil white membrane, 1/2 insulation and all necessary trim / accessories / flashings. Cost per 1 square is $800. If you are looking for an 80-mil Color IB roof, there are six standard colors available and $850 per square. For custom colors the minimum order must be 100 squares ( This is the requirement of IB Roof Systems, and we have no control over it).

One: Roof Installation Prices

Our pricing structure is based on two direct (main) variables and a number of indirect variables that affect the total price of your roof replacement project. You can expect similar pricing methods from other roofing contractors.

First cost variable: Roof Size

The most important variable is the size of your roof. The bigger the roof, the higher the roofing cost. We base our pricing on the number of Squares, where each square is equal to 100 sq. ft. For example, if your flat roof is 1900 sq. ft. it is 19 squares.

Second cost variable: Roof difficulty

The difficulty of roof installation is the second most important variable affecting the cost of your roofing project. If you have a simple roof with a minimal number of roof penetrations (such as HVAC units, sky-lights, roof drains, through-wall scuppers, vent-pipes, posts, etc.), then your roof prices will be much less than if you had a more difficult roof with multiple roof penetrations and obstacles that require more roof flashing details. These roof penetrations require a great deal of professional manual labor and time, and slow-down the entire roof installation process.

Another factor associated with roof difficulty is the roof’s present condition, and presence of gravel and/or multiple roofing layers. These layers generally require removal and consume a lot of time because it is necessary to dispose of them. At the same time, roof removal must be performed quickly to eliminate the possibility of water penetration during the removal process.

Third cost variable: Indirect costs and material upgrades

Additionally, you can expect changes in roofing cost, depending on ease of access, roof location, and material options: As far as material options go, we offer a complete line-up of IB roofing membranes for residential and commercial installations. This includes: 50, 60 and 80-mil membranes in white and custom colors, as well as specialty membranes such as ChemGuard for restaurants, and IB Traditions (Architectural shingles pattern imprinted onto the membrane) and a Slip-proof IB DeckShield for walk-on flat-roof decks. We also offer a wide range of insulation options from 2-r fan-fold foam insulation to 20-r 3.3 inch ISO board and “tapered insulation” to create a slight roof pitch for drainage purposes.

Total Cost Concept

Consider the total installation price of the new flat roof. It will include: labor, materials, warranty and other factors. Roofing materials usually carry a manufacturer’s warranty period ranging from 5 to 25 years for commercial installation. Residential warranties will range from 5-15 years, while IB has the only Residential Lifetime Warranty in the industry. However, residential warranties are more complex, as many flat roofing manufactures will not warranty residential installations, or they fill impose certain requirements before they issue that warranty.

Any roofing job should also include a Labor warranty from the roofing contractor, and usually you can also purchase additional labor warranty from the manufacturer. IB Roofs offers an ‘NDL’ or No-Dollar-Limit labor warranty, which you can purchase as an additional ‘insurance policy’ for your roof.

Flat Roofing – thinking long-term

Most roofing contractors will warranty the water-tightness of the roof they install for the minimum period required by state law or building code. In Massachusetts for example, such minimum period is 2 years. After that, you are usually on your own. We find this especially troubling when someone chooses to install an EPDM or a black-rubber roof, which is especially popular among roofing contractors for its low materials cost. However, rubber roofs usually start to leak within 5 to 8 years after they are installed, due to failing seam adhesives. By this time your labor warranty has already expired and the cost of repair is on you – the owner.

We at CoolFlatRoof warranty our jobs for the length of the material warranty! We can do so, because we exclusively use IB PVC/CPA roofs, and we know that our roofs will NOT leak due to failing seams or other flashing detail.

Two: Overheads or Cost of doing business

Insurance Costs

It is in your best interest to hire a fully insured roofing company. However, adequate insurance coverage for a roofing company is very high: Worker’s Comp is usually 40 cents for each 1 dollar of payroll, or higher if the company had some incidents in the past. Liability Insurance is cheaper, but still it is one of the most expensive in the construction industry, due to possible damages if a contractor fails do adequately protect the building from water during or after installation.

Advertising: Market acquisition cost

Another considerable overhead for most roofing companies are the Marketing/Advertisement costs, as well as Sales-force commissions and office expenses. For many roofing companies, ‘market acquisition cost’ often range from $500 – $1500 per job. These include ‘Yellow Pages’ and news-paper ads, direct mailing, and Internet advertisement, such as Google or Yahoo Pay-Per-Click ads. As a result, you the customer, end up paying these expenses, or as we call it ‘marketing taxes’, that are not directly related to the cost of you roofing job.

We at CoolFlatRoof, do not spend any money on advertisement, except minimal expenses to run our web-site (around $100/year), so we will not charge you the ‘marketing tax’. Instead, we will provide you with the best materials, workmanship and warranty, for less.

Three: Ongoing repair and maintenance expenses

Ponding / Standing Water

While maintenance for most flat roofs is mostly due to the location of the building and surrounding conditions, one of the most frequent maintenance/repair expenses is due to ponding water. Positive drainage is preferable for any flat roof. However, the very nature of flat roof construction makes it often impossible to avoid ponding water accumulation, or it is too expensive to fix it. Ponding water can be eliminated in two ways: Installing Tapered Insulation, or creating a pitch, which is often impossible due to building design. Both are extremely expensive and will cost more than the roof itself, so eliminating ponding water is often out of budget.

While most flat roofing manufactures will void their warranty if there is presence of ponding water for periods of more than 72 hours after the rain, IB Roofs are explicitly warranted against ponding water and it is proven that an IB roof will keep your home or building dry even if you have big puddles of standing water for long periods of time!

Roof Repairs

As we mentioned above, many flat roofing systems will start to leak with-in 5 to 8 years after installation. Most roof leaks occur as a result of ponding water, failing seams, and to a lesser degree, faulty installation. Other factors affecting performance of a flat roof are weather conditions and devastating UV rays of the Sun. This is very true in the New England. We have hot summers and cold winters, and the temperature can dramatically change in matter of hours. Refer to our flat roof repair guide for more information on how roof leaks occur, and what your repair options and costs will be.

In most cases these repairs will be an out of pocket expense for you, as the usual warranty period will be long over by that time. We on the other hand will uphold our warranty after the usual 2-year period, if the leak happens. However, we do everything right the first time so there is usually no need to repair our roofs!

Four: Energy costs/savings

Cool, energy-efficient roofing form IB

Unlike most conventional roofing systems such as Epdm black-rubber, or Asphalt/Tar based BUR roofs, which attract, store and transfer solar heat, white IB Roofs reflect as much as 90% of the solar heat, and carry a Cool Roof certification! Even if you choose one of IB’s color choices, they are also certified by the Cool Roof Council, by implementing highly reflective color pigments. This will save you tremendous amounts of money in reduced HVAC costs. IB roofs act as a complete thermal barrier and increase the R-value of your roof, thus also reducing your heating expenses in the winter. By adding more insulation you will further increase the thermal qualities of your roof.

Conclusion

An IB Roof is the best choice when it comes to flat roofs. An IB Roof has the lowest Total Cost combined with unsurpassed quality and longevity. If the need to repair your IB roof ever arises, such repairs can be performed even 20 years from the day of installation, with IB’s unique Hot-Air fusion welding. It is however highly unlikely, unless there is unforeseen physical damage to the membrane. Expect not to have to repair your IB roof, ever!
An IB Roof will eliminate your ponding water problems and you will avoid expensive pitch-change. IB will also save you money every year by reducing your energy cost, and you will be covered by the Industry’s Best warranty!

If you are looking for a sustainable, long-lasting roofing product for your home or business pitched roof, the Metal Roof will be the perfect choice for you. Known for decades of leaks and corrosion free service, Aluminum metal roofs are becoming the prime choice for quality and longevity oriented home and business owners looking for a new roof. With its Cool Roof properties and permanent design, metal roofs will outlast any conventional asphalt shingles roof. Metal roofs are light-weight, and do not require any structural modifications. In fact they are only 1/4 the weight of regular shingles and 1/10 the weight of slate, and ceramic / concrete tile.

Use our Flat Roof Calculator to estimate the installation cost of a new IB Roof, as well as compare it with other alternatives. You can also estimate your annual energy savings derived from installation of an IB roof.

We will aslo demonstrate how many roofers are “trained” in installation of EPDM single ply roofing systems, results of their work (our Horrible Rubber Roofs series), and explain why we recommend that you avoid installing a rubber roof on your house.

Read this and you will save yourself lots of cash and many headaches. Also see our special “Horrible Rubber Roofs” video series below!

The truth about residential flat roofing market and contractors.

This rubber roof is just 1 year old, and has been leaking since day one, until we replaced it with a lifetime IB PVC flat roofing membrane.

Rubber Roof Contractors: It is unfortunate, but most residential flat roofs are installed by roofing contractors that specialize in asphalt shingles. Since they can easily purchase rubber roofing materials from their roofing supply warehouse, and are not required to be certified installers, nor do they need any special training or equipment, they will often undertake such projects to keep their crews busy.

These are just some roof inspections that we did in the summer / fall of 2011. Look – even commercial roofs are not immune to hack roofers and faulty materials (like rubber roofing), but in residential, this is much more common.

Getting a quality flat roof installed:

The truth is that to get a quality rubber roof installed, it usually has to be done by a commercial roofing company that specializes in flat roofing. However, it is often the policy of such companies not to work with residential customers, for which there are many reasons. These contractors work with large commercial and institutional customers, employ union workers who are trained roof mechanics, specializing in their particular niche. For example, a commercial roofing contractor will have separate crews doing metal roofing or slate – these guys are “roofers”, and yet another crew doing flat roofing ONLY – these are “roof mechanics”.

A residential roofing contractor usually employs just roofers, who are good at what they do all day long – install asphalt shingle roofs, and often do not have a clue about how flat roofs work. When they get a potential client with a flat roof, they go to their supplier, ask what supplier has for flat roof, and the salesman at the supply warehouse TEACHES the roofer how to install EPDM rubber. This is not creative fiction or a product of my imagination – I see this happening nearly every time, when I come in to the supply store to get something.

“Trained rubber roofing installers”: If you are lucky, you may get a roofer that has received some sort of training about rubber roof installation. For example, one of my suppliers, provides installation training programs for their roofing contractors who install only asphalt shingles. The idea behind such training seminars is to increase awareness and solicit sales of more roofing products. A manufacturer technician provides a sample installation on a 8×8 feet demo stand.

Bellow is and example of such “hands-on rubber roofing training”.

As you can see, the roofers just sit around the demo stand while the MFG Installation technician shows them what to do. The whole demonstration took about an hour and a half, and covered thing like installing flat roofing insulation (ISO), adhering rubber to the ISO board, flashing a sky-light / chimney penetration with un-cured flashing material, installing the membrane up the vertical wall, cleaning & priming seams and installing seam tape, installing drip edge and a tape to seal the drip edge fasteners, and installing termination bar. In the same 1.5 hours we’ve also “learned” how to correctly apply yellow glue – membrane adhesive, seam primer – seam & flashing glue and how to install these systems in the winter, while violating manufacturer’s installation specs.

Out of 25 or so roofing contractors present, there were about 15 or so questions particular to the installation details. 7 of them where asked by me! Bear in mind that I already knew how to install a rubber roof and attended the event to talk to my salesman, representatives of the metal roofing manufacturer and for free refreshments

In any case, each one of those 25 or so roofing contractors, willing to learn a new, and very complicated roofing system, asked an average of 0.3 questions about this system.

Rubber roofs for residential customers: It was clear that my supplier and the roofing representatives were selling to Residential Roofing Contractors. Not once did they mention roof-top HVAC units, roof hatches, elevator shafts, gas/electrical pipes, roof drains, etc. They did however insist that the rubber is a good choice for a low slope shed dormer (without mentioning the poor low slope roof ventilation and ice dam prevention associated with shed dormers). They also mentioned that rubber is a good choice for a flat roof decks and patios.

Metal roof will protect your home form rain, snow, and most important in the north east – ice dams. Metal roofing is ice dams proof, as it sheds ice and snow, and its design prevent ice dams from causing roof leaks as is the case with asphalt shingles. You won’t have to rely on faulty and often failing ice and water barrier, or other gimmicks to protect your home from regular roof leaks, and those caused by ice dams.

Metal Roof Installation:

Installation of metal roofing materials is our specialty, and we have wide experience in dealing with even the most complicated roofs. We have installed virtually every metal roofing system there is, and have created and perfected special ways of dealing and preventing common roof leaks. Here is one of the examples of how we install metal roofing to prevent leaks through ridge vent opening.

Our unique approach to metal roofing installation:

We pay special attention and dedicate extra time to roof details which are the most susceptible to roof leaks:

• Valley flashing.
• Chimney flashing.
• Skylights.
• Roof to wall connection.
• Roof pitch change.
• Ridge vents.
• Eave flashing (ice dams preventions).
• Roof ventilation.

While any roofing can install a field metal roofing panel, the items above are what usually cause roof leaks, and where we stand out of the crowd. Installing your roof right, is our main goal!

Metal Roofing Materials that we install:

We specialize in installation of Standing Seam Metal Roofing systems with concealed fasteners, and Metal Roofing Shingles, in steel, aluminum and other metal choices. We can also install any other type of metal roof that you want, such as metal shakes, stone-coated metal roofing, corrugated steel panels, zinc and copper roofs.

While we install all types of metal roofing, the most popular choices are Standing Seam and Metal Shingles. Both of these roof types offer great weather protection, as well awesome new look for your home!

What was that? Spray foam?

Spray foam roofing goes back more than 30 years, and its popularity has been growing exponentially because of its advantages over traditional roofing systems. What advantages, you ask? Consider this:

• It’s monolithic, meaning it is one piece with no seams, which equates to no leaks
• It insulates extremely well, and can lower the temperature of a roof by up to 100 degrees!
• Long lifespan with periodic maintenance*
• Pays for itself!

Spray Foam Roof Installation Process:

Installation is simple and relatively inexpensive! There are several reasons why this particular brand of roofing is so much less expensive than traditional methods. One of the main features of SPF is that the foam itself can adhere to nearly any kind of existing roofing material, with the exception of atactic polypropylene bitumen. This means that you don’t have to pay for the roofer to remove your current roof and pay landfill fees.

Usually, two 55 gallon drums, one with an isocyanate and the other with a resin, are hooked up to a machine that heats the liquids and combines them at the best ratio for effectiveness. Then the liquids are piped into a special spray gun that combines the two liquids upon application.

Once applied to the roof (after it has been cleaned to ensure the most adhesive strength), the combined liquids begin to form bubbles on a microscopic level, expanding to 20 or 30 times their original volume, all within about ten seconds, and you can walk on it in under a minute!

The final part of the installation is to apply a UV and weather protective coating to the foam. The type of coating really depends on your budget and how much energy you want to save as well as how much additional durability you would like the roof to have. The color of the coating varies, but white is usually the best choice from an economical perspective. White will deflect the most sunlight thereby reducing the amount of energy absorbed by the roof, and in the end lowering the cost to you for cooling the interior of the building.

Gravel and stretchy, elastomeric coatings are among the more popular options for protecting the foam roof. Other options include acrylic, silicone, butyl rubber and different types of urethane spray coatings. On top of this spray coating one more coat is applied in order to help prevent physical damage from the elements, including ultraviolet sun rays. This final coat has gravel-like granules sprinkled on or embedded.

What’s in it for ME?

Well, for starters, you will begin seeing a dramatic decline in the cost of heating and cooling as soon as the roof is installed. Don’t believe me? What if I told you that when Texas A&M switched roofing systems in 1975 they switched to spray foam roofing. By making the switch to SPF, they saved so much money on energy savings that they were, on most occasions, able to pay off the construction costs within four and a half years, sometimes just two or three!

Durability and longevity are other major advantages for SPF roof systems. Excluding major weather incidents, there are usually no repairs or maintenance necessary for at least 10 to 15, maybe 20 years depending on the type of system you have installed. When the time comes for maintenance, the existing roof will be cleaned and re-coated, simple as that. A well-maintained roof can easily last 50 years or more. Talk about return on investment!

Speaking of return on investment, how much will this investment set you back? Naturally it depends on a lot of variables including where you are, what kind of foam you prefer (as in density, thickness, etc.), what protective coatings are used, the building itself and the intricacy of the job. For average SPF systems you will probably be looking at starting prices of approximately $6 per square foot and up.

I hope this article has helped you in choosing a reliable, inexpensive and green roofing solution. All that’s left is choosing the right roof repair or replacement company for you. Overall, spray foam roofing is a great flat roofing choice. That, and enjoy saving up to 50% on energy bills for years to come!

Article commentary from from CoolFlatRoof Blog editor:

Spray for roofing is a highly energy efficient flat roofing material, which combines the roof insulation with the waterproofing layer. However, spray foam roofing or SPF, require regular maintenance and complete re-coating every 10 years to maintain the protective layer over the foam. Without that protective layer, the UV rays of the sun will quickly destroy the SPF roof. It is best to coat the SPF roof with a urethane coating rather than with cheaper acrylic coating, and to add stone granules to the coating for longest performance.

One thing we want to mention is that SPF is a very popular flat roof material in the southern US, whereas up north, you will rarely see a spray foam roof (though I know of at least two large roofing contractors installing SPF roofs in the northern US with great success). Here in New England single ply membrane roofing is a more popular choice for a flat roof.

Another thing for you to consider is the situation with ponding water and how well the SPF roof will handle it. Rubber roofs for example will leak under ponding water, whereas the PVC roof with hot air welded seams will remain watertight. Although it’s best not to have ponding water at all, in many retrofit roof installations, you just can’t avoid it, so make sure that you get a ponding water guaranty from your reputable roofing contractor.

Installing a flat roof (PVC single ply roofing membrane in this case) can be a pretty straight forward process, or a very confusing endeavor because each component must be installed in a particular order. Otherwise the system may not work the way it should. Of course there is an installation spec manual from IB roofs, which we always keep handy, and actually had to use once or twice. However, this manual only shows particular flashing detail or a general way of how membrane and insulation ought to be installed. It can’t possibly cover all the specifics of the roof installation that come up in the field.

Flat roof installation – mechanically attached assembly:

A reinforce PVC single ply roof allows installers a choice of installing the roof in a fully adhered assembly (sheets of membrane glued to the insulation) or a mechanically attached assembly where each sheet or roll of the roofing material is screwed to the roof deck substrate with heavy duty, corrosion resistant roofing fasteners, and barbed plates. Each roll is screwed to the roof deck on one side, and then the next roll, overlaps a row of screws, and is welded to the first roof, right next to the screws. Then the process continues in the same manner until the whole roof is covered by the membrane.

As you can see in the roof installation picture above, the narrow roll of membrane is installed around the roof perimeter and wider rolls are in place, and are ready to be installed. However, before you get to this point, there is a lot of prep work that has to be done first, and the actual membrane installation is the easy part.

Lets start looking at the prep work, and the order in which things actually happen.

Flat roof installation – prep work – insulation, wood nailer and penetration flashing.

PVC Roofing is a very durable and long lasting flat roofing material. However it should never be in direct contact with any oil and asphalt (also oil) products, and since most other roofing materials are made with oil or asphalt, we always install a protection layer between PVC membrane and either old roof or the roof deck. We usually use insulation to protect the membrane from being in contact with asphalt and also from deck fastener punctures. Roof insulation also serves its primary purpose of improving thermal insulation properties of your roof.

Before we install insulation though, we first install a perimeter wood nailer that serves as a rigid nailing base for the PVC-coated drip edge. Once wood nailer is in place, we lay out the insulation sheets and fasten them to the roof deck, using FM Global 60 or 90 mph wind rating standard – 8 or 10 plates + fasteners per 8×4 feet insulation board (although this is unnecessary, since it is a mechanically attached system). Once the wood nailer and insulation are in place, we install one or more rows of perimeter half sheet, which is a 3 foot wide roll of membrane, vs and standard 6 feet width for field rolls. The perimeter half sheet is installed to prevent wind uplift, and is fastened either 12″ o.c. or 6′ o.c. (for high wind areas).

Flat roofing – tapered insulation:

If there is a ponding water situation, the fastest and most cost-effective way to solve the ponding is to install a so called tapered insulation system, which creates slight roof pitch, which helps divert the water in a required direction and improves roof drainage.

Tapered insulation is basically the same thing as extruded PolyISO insulation with a fiberglass facing. The only difference is that tapered insulation is wider along one edge and narrower along the other. Tapered insulation system can have a roof slope ranging from 1/8″ per one foot run, to 1/2″ rise per one foot run or more. Normally we use a 1/4″ tapered insulation system which raises roof level 1″ for every 4×4′ insulation piece.

Flat roof installation – drip edge detail:

As we mentioned the perimeter half sheet is installed along roof edges, and fastened on the inside with screws and plates – what is holding the half sheet along its outer edge? Well, this is the question that homeowners often ask me. The way IB PVC roof system is designed, allows us to attach the outer edge either directly to the drip edge or run in over the roof edge by a couple of inches, nail it to the fascia board and install a drip edge metal over the membrane.

Both ways are acceptable, but most of the time we use the second method – especially in high winds area. Once the roofing material is installed and flipped down, over the edge of the roof, we install 10 foot sections of 22 ga PVC coated galvanized or stainless steel drip edge, and fasten it to the deck with the roofing screws, either 12″ or 6″ o.c. Then we weld a 5″ wide cover strip of the membrane to the roof and to the drip edge, to seal the screw holes and bake the whole detail water-tight.

Check out our video on how drip-edge metal is installed:

Once the 10-foot sections of drip-edge are installed, the joins are sealed using an aluminum tape and a PVC patch to mack the joint water-tight and protect the patch from metal expansion and contraction. After the joints are complete, the cover tape is welded to drip edge starter and the roof itself, and its now time to do the rest of the roof.

As a side note, there are many options for drip edge detail. Although the most used drip edge is the 2 or 3″ wide face, white starter, you can also choose it to be as much as 8 or more inches wide, as well as in gravel stop style (if you need to divert the water flow or prevent it from going over the edge of the roof.

Gravel stop drip edge has a 1″ bump-out, which stops water from spilling over, and makes it run down the roof – toward a drain or a gutter. Drip edge comes in two colors – white and dark bronze, and also can be painted any other color with acrylic paint. IB roofs also offers 16 oz. copper drip edge, with PVC material adhered to the flange, and can produce any style drip edge, with different angles, kick-in or kick-out face and in various widths.

Flat roof installation – field sheets, roof penetrations and roof to wall termination:

After all edge detail is complete, we install the field rolls of membrane and all penetration flashings, such as pipes, drains, HVAC / Skylight curbs, roof hatches, chimneys, etc.

IB Roof Systems produces a wide variety of flashing accessories, which allow installers to quickly and easily flash almost any roof penetration. Since all roof components are made of PVC, they are all welded together, and the use of any adhesives or glues is completely eliminated, as well as most installation errors by roof mechanics.

All curb and up-the wall flashing is installed using a two-step process. First, the roof is terminated that the wall, and then a separate piece of membrane is installed up the wall and welded to the roof.

After the flashing is installed and welded to the roof, the inside or outside corner flashing is welded to make a permanent watertight joint.

All IB flashing accessories are made of 60-mil non-reinforced flashing membrane and can stretch to perfectly adhere to any shape of a penetration on the roof. Pipe flashings and drains have a reinforced flange to be welded to the roof.

Bellow is a video demonstrating the curb flashing installation around a skylight:

As you can see in the video, the roof penetration flashing is a very clean process, and a chance of a leak is minimum to non. Unlike flashing details on a rubber roof, where a membrane cannot and should not be terminated at the base of the curb, due to high possibility of a leak caused by adhesive failure, the hot air welding process used in sealing overlaps and seams on a PVC roof, eliminates leaks, as well as membrane pull-out caused by contraction of the roofing material in cold weather.

Flat roof installation – special flashing details:

IB roof spec manual does not cover all installation details, as in the real world you often run into situations where you have to “improvise”, while your roof must still be watertight. One such example is the ridge vent detail on flat / low slope roofs such as shed dormers. While many low slope roofs are considered “flat”, they were built as sloped roofs with ridge / soffit ventilation in mind. However, many roofing contractors that install EPDM rubber roofs, block the ridge vent opening completely to prevent roof leaks.

We’ve developed a special assembly method, which allows us to still use the ridge vent, and keep the roof watertight. We run our roof up-to the ridge opening, weld additional strip of membrane, install a 2×4 wood to raise the level off the roof, flip the strip of membrane back and wrap the 2×4 with it. This prevents wind driven water from penetrating the roof, and ridge vent + ridge cap is installed on top, 2 inches up.

As you can see, IB PVC roof can be adjusted to virtually any type of flat roof, and roof penetrations. We recommend that you check out more roof installation videos on our Roofing Videos channel on YouTube.

You can see more examples of flat roof installations that we have done all over New England: Roofing in Massachusetts and roofs in Connecticut. We provide residential roofing and commercial roof installation services in all New England states. However most of our work takes place in MA, CT and RI.

Benefits of using recycled insulation include instant and continuous financial benefits. Since we get recycled ISO board at a discount we pass on the savings to you, and with more insulation for the same amount of money you would spend on a new ISO, you will continue to save money on your energy costs year round.

But that’s not all! Although ISO insulation is not “green” per-se, using recycled insulation is a green choice since by reducing your energy consumption, it will also reduce carbon monoxide emitted into the atmosphere. It will also not go into our nation’s land-fills, therefore it will benefit the environment.

Types of insulation we use:

By default we use a 1/2 inch fan-fold Styrofoam insulation, which is mostly used when there is already some insulation on the roof. Fan-fold insulation comes with 2-R value, so it will add some insulating value to the roof. It also acts as a separation barrier between the deck or old roofing material and IB membrane. Fanfold insulation is attached with heavy-duty screws and corrosion-resistant insulation plates. It is light-weight, features quick installation and is ideal for a roof layover. It is also the most economical option.

As an option you may choose to use a common ‘new-construction’ and complete roof replacement choice of insulation – Poly ISO board, which comes in a wide range of sizes and features high R-values from 3 to 20-R. Sizes include 1/2, 1, 1.5, 2, 2.5, 3 and 3.3 inches and R-value is calculated using 6-R per 1 inch of insulation.

If drainage is a concern, ISO insulation comes in tapered design which has different thicknesses at each end, and is used to create pitch ( slope ) on a completely flat roof. Slope is usually directed toward drains or drip edges and diverts the water flow to where it can exit the roof.

We will review green roofs, not only from the Eco-friendly perspective, but also from a roofer’s point of view, as it is the roofer that makes green roofs work. We’ll also discuss recent technological breakthroughs in the green roofing industry, which have to do with simplifying design, installation, and greatly reducing costs.

Cost issues associated with Green Roofs:

Green roofs are expensive – no doubt about that. The Main reason being the relative difficulty of building and maintaining a green roof, while making sure the water-proofing membrane is intact, and performs for its specified life-period. Another reason is that all the components of a green roof (of which there are many) are expensive, and only a handful of suppliers offer them. Green Roof vegetation is also a concern, as these plants must be able to survive in a limited amount of soil and if the drought hits, these plants might not survive. It may also be necessary to set up some kind of a sprinkler system to maintain the required moisture level.

Technological (installation) issues associated with Green Roofs:

When all is set and done, a green roof will create a beautiful roof-top-garden and should significantly increase, if not double the life of your roofing membrane, as it protects the roof from the sun and the elements. A green roof will also make your building a lot cooler, as it absorbs most of solar heat.

To reap all these benefits and improvements, it is of the utmost importance to use the best available flat roofing membrane such as 80-mil IB Roof and to have a quality installation performed by a certified flat roofing installer. Just imagine that your new green roof is installed, and some time later this roof begins to leak – now you have to disassemble the green roof: remove the vegetation and soil, moisture retainers and water-flow base, while the leak may not even be where you think it is. That is why from the installation perspective everything must be installed to the highest standard; all seams must be checked and double checked in order to ensure a leak-free, functioning roof.

IB Roof and GreenRoofBlocks – the perfect combination for a Green Roof:

To make the installation and maintenance of a green roof as simple and inexpensive as possible, we chose to combine our IB Pvc roofing products with a simple, modular approach of Green Roof Blocks. These green roof sections come in 2×2′ aluminum boxes with specially formulated light-weight soil. Green Roof Blocks offer a quick installation, ease of roof repair – if there is ever a need to do some roof maintenance, all you need to do is to simply lift up the sections where you suspect the leak may be. Green Roof block is also the most cost-effective green roof you can find. Vegetation can be planted and grown before the roof is installed, or right on the roof-top.

IB Cool Flat Roof – The Best flat roofing for your Home!

An IB roof has its roots in commercial flat roofing, where the requirements and expectations of building products are much higher than in the residential market. In fact IB Roof has been chosen as the roofing choice for Hospitals, Airports and Universities through-out the country, where a leaking roof is not an option. Many of these roofs installed over 25 years ago are still performing well, without any leaks.

Ice Dam leaks and poor ventilation:

Most low sloped roofs in the northern United States have Ice Dams, which cause roof leaks and expensive roof repairs as well as cosmetic interior repairs of ceilings, walls, carpets and wooden floors. Those are the damages that you can actually see. Ice dams also create invisible structural damages which you can’t find until you open up ceilings and walls. These damages are extremely expensive to repair, as it would require to hire interior remodelers to fix structural damages, outside and inside walls, electrical systems, plumbing, etc.

Ice Dams in a nutshell: Ice dams are caused by poor attic ventilation and heat loss from the inside of your living space. Large piles of snow will accumulate on your roof after a snow storm. If your attic is improperly insulated and ventilated, the warm air escaping from your living area into the attic, will melt the snow. The water from melting snow will run down the roof and refreeze, usually along the eaves of your roof. These are Ice Dams. The more snow is melting the bigger Ice Dams you have. After some time, the ice dams become so big, that the melting water cannot travel downward anymore, so it starts to travel upward underneath the roof shingles or rolled roofing seams. As it freezes under the roof, warm air melts it, and it slowly starts to drip inside the attic, causing all of the above and below mentioned problems.

It becomes a vicious cycle were more heat loss creates more ice dams, which causes more damages to structural walls and insulation, destroying your home from the inside, increasing your energy-related expenses, and causing more heat loss, which creates bigger ice dams…

One negative effect caused by Ice dams, and which many homeowners neglect to address is the wet insulation in the attic and inside walls. When insulation gets wet, you loose insulating value, so your energy costs increase, as heat loss in the winter drives up your heating bill. The same happens in the summer with cooling. Also, mold begins to grow in the attic and inside walls, which cause and/or aggravates allergies, asthma and other respiratory illnesses.

Solution to Ice Dams problems on low-slope roofs:

IB roofing membrane is perfect way to eliminate Ice Dams on a low slope roof, as it is a seamless blanket over the entire roof. Hot air welded seams prevent water from backing up and re-freezing as is the case with shingles and rolled asphalt roofing, therefore eliminating the effects of Ice Dams. Also, Most of the snow will actually slide off the IB roof, thus there will be a minimal Ice and Snow accumulation along the eaves.

Additionally, we’ve designed a special Ridge Vent system, which we use on every low-sloped roof with ridge/soffit ventilation in place. This system prevents the wind driven water form entering your attic space through the holes in the ridge vent, while allowing the warm air to escape the attic.

Now you too can have this outstanding roof installed on your home. IB make the perfect choice for any residential flat and low-slope roof. IB roof will give you years of worry-free service, and make your home more energy efficient, as well as provide a transferable Lifetime Warranty! IB will also add beauty and usability to your home with its specialty Traditions & DeckShield membranes.
