A flat roof is a popular type of roof used in commercial buildings. In contrast to the sloped form of a roof, a flat roof is horizontal or nearly horizontal. Materials that cover flat roofs allow the water to run off freely, protecting your Chicago business from water damage.
Traditionally, flat roofs use a tar and gravel based surface, which (as long as there is no pooling of water) is sufficient to prevent penetration. However, these surfaces tend to fail in colder climates, where ice dams and snow pack could block the flow of water. Similarly, tar-based roofs tend to be sensitive to sagging of the roof, affecting the subtle grading of the surface.
Modern flat roofs use a continuous membrane covering which can better resist water pooling. These membranes are applied as a continuous sheet where possible, though sealants and adhesives are available to allow for bonding multiple sheets and dealing with structures penetrating the roof surface.
