TPO Roofing – Is it Good Or Bad For the Roofing Industry And Building Owners?

Posted on by ibroofma

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 in 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 is now the fastest growing commercial roofing product.

TPO Roofing Product for Residential Contractors

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 that would allow these guys to 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?

Green Roofing Contractors – How Are We Different From Other Roofers?

Posted on by ibroofma

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).

What is a “green” roofing contractor?

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. Continue reading →
