Flat Roof Repair & Replacement

Flat roofs are most commonly found on commercial buildings. They are level in comparison to sloped roofs. Flat roofs have a pitch up to 10 degrees. One of the advantages of flat roofs is that they can be used as living space.

The roofing materials used on flat roofs include Asphalt, EPDM, PVC, TPO, and Modified Bitumen. Metal can also be used on flat roofs – copper, lead or tin.

The primary purpose of the membranes used on flats roofs are to waterproof the roof area. Materials that are used on flat or low slope roofs are designed to allow the water to run off to drainage areas.
