If you are a homeowner and you are planning to replace your roof soon – whether because it leaks, or it is getting old and you want to replace it before its starts leaking – a metal roof is one of your best options as far as roof replacement. However, metal roofing costs might be a factor in your re-roofing decision. The asphalt shingles roof costs about 2-3 times less than a metal roof, depending on various factors. At the same time, a metal roof will last a lifetime, whereas most asphalt shingles roofs will need to be replaced within 15 years. Also, the cool roof coating on metal roofs will make them much more energy-efficient, which will substantially reduce your cooling costs, even in the mild climate of New England.
The good news is that the government offers a 30% cool roof tax credit, with a $1500 cap, for any qualifying metal roof installation, and all our metal roofs do qualify for this tax credit, as they come with a cool roof coating and are Energy Star certified. There is a catch however – the tax credit will expire on Dec. 31, 2010. So if you are considering installing a metal roof, doing so before the new year is the way to go.
Consider this – most residential metal roofs will cost about $15000, so the tax credit is about a 10% discount off the total roof cost, and most metal roof installations will qualify for the full amount of this tax credit. Basically, now is the best time to have a new metal roof installed, because we don’t know when or if the cool roof tax credit will ever be reinstated.
Benefits of installing a metal roof:
Metal roofs provide a much longer lifespan, compared to regular asphalt roofs, as well as supreme weather protection for your home. Most houses in the north east region, get Ice Dams along the roof eaves, and the way an asphalt shingles roof is designed, allows the ice dams to cause roof leaks, which in turn can cause substantial structural damages, and will require other repairs to the roof and the interior of your home.
Metal roofs offer inherent protection against ice dams. The interlocking design of metal roofs will prevent ice dams from penetrating your roof. Also, most of the snow will just slide off your roof, even before ice dams can form. Read the rest of this entry »
In July of 2010 we installed a new IB PVC flat roofing system with custom-made copper drip edge metal, on a new construction home in Newton, Massachusetts. This house is located around the corner from Newton Center.
In this job profile we will demonstrate all stages of this roof installation, and show the new Copper Drip edge, which IB roof systems has recently introduced and made available to its certified roofing contractors.
First, let’s go over the roof specs and details. The building on which the roof was installed is an new construction garage / guest house with two car bays on the first floor and guest rooms with a balcony / deck on the second floor. Because of heights limitations in Newton, MA, the top portion of the roof had to be flat, with a little slate roofing mansard around the roof perimeter, to resemble the slate roof on the main house. The home owner chose IB PVC Flat Roof, as the roofing material for their building project.
The roofing membrane we used, was an 80-mil white IB PVC roof, mechanically attached to a wooden substrate, over 3 inches of tapered ISO insulation. All seams were hot air welded using Liester welding equipment.
Around the roof perimeter, we installed IB’s new Copper Drip edge metal with PVC coated flange, which allows us to seamlessly integrate copper with an IB roof. The PVC cover tape is welded to both the roofing membrane and a drip edge metal, leaving exposed copper to give this roof a beautiful look of a classic slate roof with copper flashing.
On the second floor, we installed the same 80 mil roof with differently shaped copper metal, over a walk-out balcony deck, and additionally flashing the roof and the door opening, with IB’s pre-manufactured roof flashing accessories. After the roofing membrane was installed, a floating roof deck was installed on top. Read the rest of this entry »
Update – Oct 26, 2011: Exactly 2 years after the initial Sarnafil PVC Roof repair (read details below) I went back to that roof. This time there were 17 new holes in the roof. I repaired it once again with IB PVC flat roofing material. Check out the full review of this latest PVC roof repair in Needham MA, as well a overview of a DuraLast PVC roof that we repaired on a 22-story apartment complex in Cambridge MA.
Update 2: a Trocal roof repair also reviewed below – section of that roof has completely shattered over past winter, and we had replaced it with IB PVC Flat Roof in the spring of 2011.
Check out the video of this new PVC Roof repair:
Original PVC Roof repair article
PVC roofing is one of the longest lasting flat roof membrane systems, and most PVC roofs installed, will last in excess of 25-30 years. PVC roofing utilizes Hot-Air welding of the seams, which allows the roof to remain watertight for many years, as there is no adhesive to fail ( as is the case with EPDM rubber roofing ). Still, even PVC roofs can leak. Sometimes because of poor installation, and sometimes because of physical damage to the roofing membrane. You may have heard about the Trocal PVC roof failures, which was the only major case of PVC roof failures (below we will explain how Trocal roofs failed).
In this article we will discuss and demonstrate the PVC roof leaks and repair procedure, based on two recent repairs we have done. First, please note that even if your PVC roof leaks – you should not be too worried – PVC roofs are rather easy to repair, and you will rarely need to replace your entire roof.
What makes PVC roofing so “awesome”?
Awesome is a strong word to describe a roofing material, and yet that is what I think of PVC roofing. Although PVC is not the most durable (strong) flat roof, with hot air welded seams, you can install PVC on almost any roof, even if there is ponding water. Another great feature of PVC roofing (IB flat roof in this case, as PVC roofs from other manufacturers may not perform the same as IB roofs), is the fact that even after 30 years on the roof, the material is still flexible, and you can easily weld new material (such as a patch, or a flashing) to it. Also I should mention that most PVC membranes are compatible with each other, though if you use PVC materials from different manufacturers, or unapproved installer, you will probably void your warranty. At the same time, most TPO roofing membranes (which are similar to PVC roofs) will loose elasticity, and ability to be welded in as little as five years after installation.
As promised – a quick look into why Trocal PVC roofs failed on a massive scale, forcing the company to be sold to another large roofing materials manufacturer.
Trocal PVC roofing was one of the first commercially available PVC roofs in the US, and they worked great at first. But they had one major drawback – they were unreinforced (today, most PVC membranes are reinforced with polyester scrim sitting between the top and bottom ply of the membrane). When the ambient temperatures were below freezing, a Trocal roof could crack or shatter if you simply stepped on it, especially if it was really cold. Later, all PVC manufacturers switched to reinforced membrane, and some would add special chemicals to increase the elasticity of the membrane. Today, unreinforced PVC membrane is used only for flashing accessories such as inside / outside corners, pipe flashing, etc.
The repair of Trocal PVC Roof:
This Trocal roof sustained damage from a falling tree branch in December of 2009, and cracked along the edge. Although the roof was over 20 years old, it was still fully weldable and we were able to repair it with new IB PVC roofing membrane in Jan. 2010. We removed the damaged section of the roof, cleaned the surface with MEK solution, installed new PVC coated IB Drip Edge metal, and welded 50-mil white IB roofing membrane. The repair was performed in a 25 degrees outside temperature, so we had to take special care not to damage the rest of the original roof. Read the rest of this entry »
Most solar systems are installed on a roof of a house or a building. The exception are solar farms or ground-mounted solar installations, but these are rare, and usually 100% commercial solar systems. The reason most solar systems are installed on a roof is because of limited space – especially in the urban environment.
on the other hand, roofs represent significant unused space, and are usually not shaded by trees, nearby buildings, etc – they are the highest point of a building with great sun exposure, which makes them perfect to install solar panels on.
In this article we will discuss solar roofing systems, which integrate roofing materials with solar PV panels or solar thermal systems. Although most roof-mounted solar systems are installed on top of an existing roof – be it an asphalt shingles roof or any type of flat roof – these solar systems are not integrated into the roofing material, and therefore are not solar roofs.
What is solar roofing? Roof-integrated solar systems explained.
Solar roofing is a final product which integrates a Solar Panel with the roofing material suitable for either a sloped or a flat roof. The solar panels used in solar roofing are usually thin-film photovoltaic laminates. Most popular Solar PV laminates commercially used today, are the Unisolar thin-film PV panels.
Unisolar thin-film PV laminates were originally designed to fit into and be integrated with standing seam metal roof panels. Unisolar panels are 15.5 inches wide and fit perfectly into a 16″ standing seam panels, and are attached or laminated with special butyl adhesive that is on the back of each Uni-solar PV panel.
As time progressed and solar integrators were having flat roof leak repair issues with solar systems they installed on flat commercial roofs. After they installed solar mounting racks and attached them to the roof deck, the fasteners would start leaking after a while. Roofing manufacturers adressed this issue with different versions of flat roofing materials that integrated Unisolar PV panels – one such system is IB Solar Roof. There are many types of both solar metal roofs and solar flat roofs, using solar PV panels from various manufacturers (though as I said, most do use Unisolar PV laminates).
In this article we will discuss different types of solar roofing systems such as Solar Metal Roofing, Solar Flat Roofs, and Solar Shingles that get integrated with regular asphalt shingles roofs.
Solar Metal Roofing
The most common type of solar metal roofing is the standing seam metal roof with integrated Unisolar PV laminates. Unisolar PV laminates were initially designed to fit in the pan of standing seam panels, with the connection terminals concealed by the ridge cap. Because the connectors or terminals of these PV panels are not UV stable, they need to be hidden from the sun, while the rest of the panel is of course exposed to the sun to generate solar electricity.

In April we installed a new lifetime Steel Metal Shingles roof on a house in Attleboro, Massachusetts. The house is located on a beautiful quiet street not far from Attleboro Center, as well as Mass / RI border. The new metal roof replaced and old, failing asphalt shingles roof, with some shingles blown off by the wind.
The Metal Roof we installed was a Tamko Steel Shingles with real slate look, in the beautiful Sequoya Red color. Steel metal shingles are an interlocking metal roof system, where each shingle is locked on all four sides and is held in place by clips and roofing nails, and the other six shingles around it.
Steel shingles metal roofs offer great flexibility in terms of installation, excellent water-tightness, and prevent Ice Dams formation as metal roofs shed Ice and Snow. On top of being an excellent solution to roof leaks and Ice Dams, metal roofs last in the range of 50 years or more!
Metal Roof installation.
The old roof was two layers of asphalt shingles, which according to building code, must be removed before the new roof is installed. Removing the old roof is also beneficial in terms of removing extra weight off the house. Although metal roofs are VERY light, weighting 40 lbs per 100 sq. ft. in aluminum, and about 65 lbs. in steel shingles, they will not add nearly as much weight as 1 layer of asphalt shingles (about 275 lbs per 100 sq. ft.), and can be safely installed as a second layer, it is a good idea to do a full tear off, to allow the repair of any rotten wood, and to improve roof ventilation.

Metal roofing is an excellent choice for quality-minded homeowners, because a metal roof is virtually the only lifetime roof system that is light-weight, long-lasting, and most of all – affordable. If you compare prices of a metal roof to slate or clay tile prices, you will realize that an average metal roof will cost you only about one third the price of natural slate, while it will look the same or better, and last at least as long.
There are many styles of metal roofs and many choices for roofing materials – your choices range from galvanized steel / aluminum metal roofs, to premium metals such as zinc, copper and stainless steel roofing. You can choose between a “standard” vertical panel (standing seam) metal roof, or a metal roof made to look like either cedar shingles, shakes, natural slate, or flat and barrel tile.
You will also get a wide range of colors to choose from. The result will be such that you will get the look you want with the price you can afford, and the long-lasting performance of metal roofing.
Metal roofing – premium roofing material at down to earth prices:
There is much confusion about the prices of metal roofs, as there is a wide range of metal roof styles and materials to choose form, with some costing a lot more than others. In this metal roofing prices guide, we will show you how much you should expect to pay for different metal roofing systems, and how the choice of metal roofing materials will affect your roofing cost. But before we jump into roof pricing for each type of metal roofs, let me clarify one thing: metal roofs are pricey as compared to asphalt shingles roofs, but keep in mind that metal roof is a lifetime roofing material and so should be compared to its counter-parts in the roofing market – other lifetime roofs, such as natural slate, clay Spanish tiles, concrete tiles, and lately, synthetic slate roofing.

Last week, Boston was a host to hordes of roofing sales people, roof manufacturers’ reps and local roofing contractors from all over Massachusetts and New England. It was the NERCA (North East Roofing Contractors Association) annual roofing convention, where most roofing materials, tools and equipment manufacturers were present, promoting their new products and services.
After being to a few of these shows already, I have found that they don’t get any more exciting, but it’s always nice that NERCA sets up up open bars with semi-decent wine, and cheese / crackers / fresh veggies & berries tables. I think that for roof sales professionals, these roofing conventions have become a boring necessity, as all they do is schmooze with each other and talk about competition. As for me and other roofing contractors, we can always find some new and exciting roofing materials and roofing tools, equipment and services, such as infra-red roof scanners, roof lifts, a hydraulic-powered dumpster, which can be lifted to the roof level to speed up roof tear-off and clean up process. As a Flat Roofs contractor we were there supporting IB Roofs, which had a booth there, and I got to meet IB’s new Regional Manager Dana Spurgeon, as well as IB’s local reps in Massachusetts – Jerry Lang and Kevin Laprte (whom I already know of course).
Roofing Equipment presented at the Boston Roofing Show:
Besides the obvious and now ritualistic visit to the IB Roofs stand, I wanted to find as many cool, interesting and innovative roofing products at this show, and quickly wondered off, to explore the unknown. My first find was an excellent new automatic hot-air welder by Leister – the new Varimat V2. Read the rest of this entry »
Recently, the MRCA (Midwest Roofing Contractors Association) issued a warning bulletin regarding TPO roof failures caused by the sun’s UV rays. You can read more about it on our original TPO Roofing page, as well as my commentary on this bulletin.
At the same time, major roofing distributors are shamelessly pushing TPO into the market and onto the roofing contractors without much regard for home and building owners. Bear in mind that because of low prices and “same cool roof” and “welded seams” qualities as PVC roofing has, TPO roofing is now the fastest growing commercial roofing product.
Here is a good example – pictures below will show you “manufacturer’s” stand showing a TPO roof designed for residential roofing contractors.
Why residential roofing contractors? Well, the way I was told, these are the roofers who can’t afford to spend $12,000 on hot-air welding equipment, so the roof manufacturer created a system so these guys too could jump on the TPO band-wagon.
(The TPO stand above, is displaying outside corner flashing, inside corner flashing, pipe boot, and drip-edge details. When I asked about the caulking along the seams, i was told it’s not caulking. It’s seam tape )
Here comes the best part! This TPO roof system is put together with … no, not hot air. Seams are primed and a seam tape is used to seal overlaps! But, it gets better – since there is no uncured flashing material in the TPO world, and these “shingle-bangers” don’t have Liesters (hot air welders) nor do they want to buy them, since the cheapest one – a hand welder – is $450 before tax. So, this manufacturer uses white EPDM uncured flashing for all detail work such as inside / outside corners, posts, curbs (skylights, chimneys, roof hatches, HVAC equipment, etc.). EPDM rubber on TPO – really? Read the rest of this entry »
The term “green” has become very popular during the last decade and consequently overused, misused and abused. Anything and everything can be called “green” today. To make money and to attract environmentally-conscious customers, people will call themselves and their products “green”, even when it is just a blatant lie to confuse uneducated consumers. Being a roofing contractor, I will concentrate on roofing products and services. For example, many asphalt shingles manufacturers now offer “cool” and “green” shingle products – to me it’s just a shameless tactic to sell the same NOT-GREEN crap that is painted A different color (usually some shade of white). Excuse me, but asphalts shingles are not green, period! TheY are made with asphalt, can’t be recycled and end up in landfills in 10-15 years.
Since the term green is very vague and can be interpreted in many ways, I’ll offer my vision of “green” – a green roofing contractor to be exact, which describes the way I think and try to operate our roofing business. I want to mention that when I say “green roofing contractor”, it has nothing to do with with a roofing contractor installing green roofs or roof-top gardens. To me a contractor installing roof-top vegetation is a highly-specialized landscaping company, but not a roofing contractor (unless they also install the actual flat roofing membrane to waterproof the building).
In my mind a green roofing contractor is a company that works hard to help protect environment and reduce its energy consumption and green-house gas production or carbon footprint. Sure, almost any company will have a carbon-footprint as it’s nearly impossible to be carbon-neutral, but there are many ways to achieve a much lower carbon footprint. Read the rest of this entry »
Replacing an old rubber roof with IB PVC roofing membrane in Lowell, MA.
In the beginning of Dec. 09 we installed a new IB PVC roof in Lowell, MA. This roof replaced an old EPDM rubber roof which was installed by a hack roofing contractor about two years ago, and was failing miserably, due to two factors: poor roofing system design on the part of EPDM roofing, and horrible installation by the roofing contractor. I suspect that this contractor had almost zero knowledge about flat roofing and rubber installation. Before I go into the IB roof installation, I want to talk a bit about the two factors mentioned above that contributed to the roof failure.
The roof actually consisted of two roof sections not connected to each other. One smaller roof in the front of this historic home was about 100 sq. ft. in total, but its shape made using a rubber roof not feasible due to limitations / flaws of rubber roof system design. Another roof section was just over 300 sq. ft. and covered an enclosed porch in the rear of the house. This section had a low slope to it (about 2 in 12 pitch) and a hip roof design. The failure of both front and rear roof sections was the result of bad installation by the roofing contractor and EPDM rubber roof shrinkage, as well as seam adhesive failure.
Rubber roof failure due to EPDM flaws and limitations and faulty installation by a roofing contractor:
When EPDM rubber roofing membrane is installed on a roof connected to a wall of a building, the membrane must be laid down with a flap going up the wall – in essence, the wall flashing and the roof covering must be done with one piece of material to eliminate leaks in the the roof to wall connection. Therefore, the field sheet of roofing membrane is only held down by glue (which happens to break down after 5-7 years). While in some cases this work out fine, very often the rubber shrinks and pulls away from the wall-to-roof connection point. This results in either the detachment of wall flashing, membrane pulling away from the corner of roof to wall connection, or in some rare cases, when the wall flashing is securely attached to the wall, the shrinking rubber roof may pull the wall with it – for example it can pull a brick parapet wall.
