Lowcountry Roofing: Reliable Roofing Contractors in Charleston

Flat roofs are becoming increasingly popular for residential homes, but when homeowners decide to have a flat roofs installed on their homes, they still has to decide what style of flat roof they want. Charleston roofing experts are available to help people make informed decisions, but in the end, it comes down to personal taste and which flat roof offers the best benefit for their individual needs.

Traditional flat roofs are made using the built-up roofing style, which is the type most homeowners are familiar with. Flat roofs made in this fashion contain multiple layers, and three or more of these layers are made of waterproof material. Several waterproofing materials are needed when designing a flat roof since it has little to no slope. Between each of these waterproof layers is a coating of black tar, and to make the flat roof heavier and protect it from the sun, gravel is usually added on top.

A more uncommon flat roof style is the modified bitumen. Unlike built-up roofing, the modified bitumen is a single-ply roof that has a mineral-based surface. It comes in two types: torch-down and peel and stick. Torch-down is not used very often because it can be a fire hazard. No matter what type a homeowner chooses, he’s likely to save money on his energy bill with a modified bitumen flat roof thanks to the light color of the mineral-based surface.
