Roofing Materials For a Flat Residential Roof

A flat roof can often be highly effective on a residential building. Any roof is most effectively installed by a professional. If you are considering building one, the list below contains several types that may be worth pursuing.

Build-up Roof

A build-up roof is traditionally constructed using a combination of hot tar and gravel, though newer models may incorporate fiberglass membranes. This type of roof has unique fire-resistant capabilities, and it also tends to be a relatively affordable material to use. However, it can often be messy, particularly during installation.

PVC Roof

Polyvinyl chloride can also be an effective and durable material for a flat roof. A major advance of PVC roofs is the ability to reflect sunlight, ultimately reducing cooling costs. However, PVC roofs are not particularly strong and therefore cannot support extensive weight. They also may be more prone to leaks, due to shrinking.

Modified Bitumin Roof

Modified bitumin tends to be fairly easy to install, relatively affordable, and an effective cooling material. However, if installed improperly it may be prone to tearing, making installation by a professional a sound choice. Ultimately, though, because it can be especially flammable, its use is not typically recommended in inhabited residential buildings.

EPDM (Ethylene Propylene Diene Monomer) Roof

An EPDM flat roof is essentially a type of rubber roof. It can be easy to install, and is fairly resistant to wear, as well as relatively easy to repair. However, it does tend to absorb more heat than other roofing types. While lighter colored EPDM roofs are available, the cost tends to rise.

Ultimately, a flat roof can be an effective addition to a residential building. While some types of flat roofs are easier than others to install, it is always best to hire a qualified professional for installation, to ensure the roof is installed safely and securely.
