You probably learned about membranes in elementary school. Perhaps your teacher explained that a cell without a membrane would be like a bedroom without walls, or, considering our topic, a house without a roof.
When the price of oil soared in the 1970s, pushing up prices for asphalt roofs, the industry responded with the EDPM – a kind of synthetic rubber – membrane roof, and other materials, such as thermoplastics like PVC and TPO. Due to the success of these alternative products, asphalt became less popular as a roofing material.
6 Benefits Of A Flat Membrane Roof
1. Here Comes The Sun
A flat membrane roof outshines an asphalt roof when it comes to fending off the damaging rays of the sun. Why? Asphalt expands and contracts as temperatures change, expanding when warm and shrinking when cold, which results in unwanted small cracks. These small cracks eventually develop into large highly problematic cracks. Flat membrane roofs are much more flexible than asphalt roofs and hence last longer, and require less maintenance.
2. Quick, Grab A Bucket!
No business owner wants to see a pool of water growing larger on a concrete floor because of a leak in the roof above it, and we all know that repairing a leak quickly and completely is essential for the health of a roof and the structure it protects.
For a variety of reasons, it is typically much easier for a roofing professional to find the source of a leak on a flat membrane roof than on an asphalt roof. And, it is relatively easy to fix the leak on a membrane roof if you have the right knowledge and experience.
3. Asphalt Roofing Systems Are Heavy, Man.
Asphalt roofing typically involves gravel, and lots of it. Why? Asphalt roofing needs to be protected from the suns rays. That is one of the biggest reasons why shingle roofs and modified bitumen roofs have granules on them. The sun shines on the stone or granules instead of the asphalt system itself. If the sun shines directly on the asphalt, cracking occurs.
Flat membrane roof systems have their own U/V protection built right into the membrane. Typically, a roof membrane roof system consists of 3 layers. The top layer is the weatherproofing and U/V protection, the middle layer is the scrim, and the bottom layer helps hold everything together. As a result, most membrane roof systems weigh less than 1 pound per square foot, where most built up asphalt roof systems weigh 5 to 7 pounds per square foot if stone is applied at a typical rate.
4. Membrane roofs are easier to install
Membrane roof systems are typically much easier to install than asphalt. Membrane roof systems, like EPDM, TPO and PVC, are installed in one ply, hence the term single ply. Asphalt roof systems, however, are typically installed in 3 to 5 plys, which takes a lot longer. And, in some cases, installing an asphalt roof system requires the use of hot asphalt, which is difficult and dangerous to install.
5. You Save Money
Membrane roof systems are less expensive than asphalt. Not only has the cost of asphalt risen in recent years, but asphalt takes a lot longer to install. This translates into savings in both material costs and labor costs for a shingle ply membrane roof system.
6. Let’s Put It On The Roof
If you own a business, you know that you have to invest in a reliable air conditioning unit, and, depending on how much space you have, it can be large. It is much easier to properly flash a rooftop unit into a membrane roof system than an asphalt roof system.
