FLAT ROOF

Installing a flat roof is creating a barrier that will be impenetrable to water. That means seams are a major no-no. In order to avoid having seams, your traditional materials such as asphalt, concrete, and tile shingles as well as corrugated metals are out the window. Flat roofs require an application process of sealing and coating with materials such as PVC, TPO, EPDM Rubber, BUR and Silicon Spray, each having their own distinct benefits.

 

PVC is one of the most popular flat roofing materials. PVC roofs are known for their strength and durability. Their minimum breaking point is 300 pounds per inch, which is much higher than the industry standard 200 PPI. Most PVC membranes reflect the sun’s rays making them very energy efficient, and they can be mechanically attached or fully adhered to their roof deck system. When installed, the PVC’s seams are welded together which strengthens and reinforces the material, further protecting your home or office from leaky seams.

 

EPDM Rubber is more commonly known as a “rubber roof” and is one of the most popular flat roof choices for commercial buildings. One of the biggest advantages of EPDM over a PVC roof is affordability. In comparison, EPDM rubber costs much less than PVC single-ply membranes. EPDM can reach dimensions of up to 50 feet by 200 feet. The manufacturers create such large sheaths to avoid seams, which in turn will protect consumers from roof leaks. EPDM can be installed fully adhered or mechanically attached. Much like PVC, EPDM is a single-ply, energy efficient and environmentally friendly flat roof option. Depending on the type of rubber roof you choose, EPDM can last anywhere from 10 to 15 years.

 

TPO is another single ply roofing membrane. TPO is comparable in pricing to that of a rubber roof and features the reinforced durability of welded seams much like PVC membranes. Compared to the competition, TPO membranes are more readily available in reflective colors, hence their recent rise in popularity. Like EPDM, TPO can also be mechanically fastened or installed with self-adhesive. TPO’s lifespan can range anywhere from 15 to 20 years depending on the product you choose.

 

Built Up Roofing is better known as “tar & gravel” or “hot mopping.” Many home and commercial building owners trust Built Up Roofing as their number one choice of flat roofing. BUR has been in use for over 100 years and is still one of the best low-slope or flat roofing systems available today. Built Up Roof installations are a multi-ply application process using hot asphalt. You can enhance the energy efficiency of your roof by choosing a top layer of reflective coating or increasing the durability with gravel. BUR’s greatest feature is the ability to endure heavy foot traffic and can last between 15 to 20 years.
