This is part 2 of our rubber roofing guide. In this part we will explain shortcomings of rubber roof (such as inherently faulty design), inability to hold ponding water and generally short life span, etc.

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.

Here you will find video profiles of roofs we installed in Massachusetts, Connecticut and Rhode Island. These videos will demonstrate how the roof was installed from beginning to end, as well showcase short excerpts taken during roof installation, such as installing standing seam metal roofing panels, or hot-air welding of seams on IB PVC roof installations. Most videos are available in High Definition (HD 720P) to better show the details of the work performed.

You can also check out our roofing job profiles gallery which shows some of the roofs we installed in MA, CT and RI. Roof video profiles here will be presented in no particular order. If we’ve already written a full job profile, we’ll reference it below the video.

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.

Rubber roofing (EPDM single ply membranes) it the most common flat roofing system in New England (MA, CT, NH, RI, etc.) and the rest of US flat roofing marker – most people refer to a flat roof as “rubber roof”. The main reason for such popularity of rubber roofs is the lower initial roof price. However, rubber roofs have many inherent problems, which cannot be solved by technology, because of the rubber roof’s design, as well as issues with unprofessional roofing contractors claiming to be “rubber roofing pros“.

What you need to know about Rubber Roofing:

There is much confusion about rubber roofing, as well as misunderstanding of its benefits and limitations. In this article we will try to clear up the confusion and show you that rubber roofing is NOT the best flat roofing material, and there are better and cheaper alternatives to rubber.

EPDM Rubber roofing and flat roof homes.

Homeowners with flat roof homes often find themselves in a situation where their roof starts to leak rather unexpectedly – i.e. only after a few years since the roof was installed. This for the most part happens to homes that have a rubber roof on them. While most flat roofs will only last 10-15 years, older systems such as Tar & Gravel, Bur and in some cases Modified bitumen roofs are usually installed by roofing contractors that are somewhat specialized in their scope of work – these are “the old-timers” or former union guys that decided to try their luck working for themselves, and they actually went through special training and have years of experience. The problem is that roofing systems they install do not last long for many reasons outside the scope of this article.

Homes that have a rubber roof begin to leak well before their minimal life expectancy is reached because in many cases they are roofed by your typical shingle roofing contractor that is so confident in his/her abilities, and a rubber roof is merely a roof with a low slope.

Why rubber roofs are so popular?

The truth is, rubber roofs (EPDM) are the most used flat roofing products in the US / Canadian commercial roofing market. Rubber roofs we first put in service over 40 years ago, and since gained popularity among roofing contractors and their customers. The reason for such success lyes in the condition of the flat roofing market at that time and the available alternatives.

Back in 1960′s oil was still very cheap, it was more than a decade before the oil crisis of the 70′s and there wasn’t that much demand for oil. The oil refining process was far from being efficient and the industry was looking to get rid of many by-products of the oil refining process.

At the same time, the flat roofing industry was the same as at the turn of the 19th century, and the most common product to use on a flat roof was either a BUR (built-up roofing, using multiple layers of tar paper, saturated in hot tar or hot asphalt) or Tar & Gravel roofing, which was essentially a BUR roof with gravel added for additional protection. Flat roofing technology has not changed for 100 years and contractors needed a new, easier to install and cleaner product, hence, the EPDM was born.

EPDM consists mainly of oil (carbo-hydrate) based by-products with some modifiers and stabilizers added to extend its service life. Rubber roofing was cheap to produce, easier to install than conventional (BUR) roofs, did not require any special equipment to put it down and the membrane could potentially last for decades, as it was UV stable and did not break down when exposed to the weather.

Because rubber roofing was cheap, quick to install, and offered a potentially long service life, and with lack of any opposition from better roofing products, it quickly became the king of flat roofing and the pioneer of the single-ply flat roofing market.
