Because any flat roof is inherently prone to leaking, it’s important to hire skilled installers whenever flat roofing is repaired, replaced or installed.
This roofing category is often grouped with low-slope roofing because many of the roofing treatments are the same. The most common flat-roofing materials used on residential and commercial buildings today include single-membrane systems like EPDM or rubber roofing, thermo-polyolefin (TPO) roofing and PVC roofing. Metal roofing is sometimes used on low-slope roofs, but not on flat roofs.
High-density Spray Polyurethane Foam (SPF) roofing is a system that coats the roof with a continuous layer of foam insulation that can also serve as the finished roof surface (as long as a protective coating is applied over the foam).
