Flat roofing systems are different from their sloped counterparts in almost every way, and they, therefore, contend with unique challenges. The biggest threat to them is standing water, which can easily cause leakage due to hydrostatic pressure or even roof collapse.
To prevent issues, you should use the top materials. Below are four of the best materials you should consider for your residential roof replacement:
An acronym for built-up roofing, it was the most popular solution for flat-roofed structures until single-ply membranes were introduced to the market. It consists of watertight layers covering the roof made from tar and gravel. Not only does it deliver excellent resistance, but it is also easy to repair or re-surface. It’s your safest bet if your roof has to deal with regular foot traffic.
Short for modified bitumen roofing, MBR was the first alternative to BUR after 60 years of monopolizing the industry. This system features overlapping rolls to form wide seamless areas to help prevent water infiltration. It requires fewer materials than its predecessor, making it less complicated to apply. Lending itself to different installation methods, it combines the toughness of BUR with the ease of application of single-ply residential roofing membranes.
Made from synthetic rubber, EPDM (ethylene propylene diene monomer) membranes can go back to their original shapes after getting stretched out. In other words, it can retain its mechanical properties for an incredibly long period. Available in wide, waterproof sheets, it can completely encase your roof with just a few rolls.
A shorthand for thermoplastic olefin, TPO membranes are the newest and the hottest flat roofing material on the market today because of its affordability. Like PVC (polyvinyl chloride) sheets, TPO is designed to mimic the elasticity of traditional rubber roofs, but it has greater durability with hot air-welded seams. In addition to being tear-resistant, TPO membranes can help reduce your roof repair and energy costs by reflecting most of the solar heat.
