The roof of a business does more than keeping out the rain. It also protects important assets and clientele. Unfortunately, a leak can happen when a business least expects it. One of the more common reasons a leak occurs is the type of roof typically used by an unscrupulous Commercial Roofing Company. This sort of roof is commonly known as a low sloped or flat roof because it is frequently used on buildings with a roof that appears to have no pitch. There are several kinds of commercial roofs including the BUR (built-up roof) system, TPO, and EPDM.
BUR consists of various layers of a tar-based roofing felt coated with a layer of asphalt and covered with ballast. It may be as thin as three layers and thicker than twenty. In fact, the thickness often depends on the strength of the decking. One of the benefits of BUR is easy repairs. This can be useful when the comfort appliances require repair because they are often located on the top of the building. BUR can be damaged when contractors walk over the roof or drag equipment across it. Repairing the roof is usually a matter of applying a hot patch over the damaged area and restoring the ballast. If the damaged area is large, the contractor may opt for placing a membrane over the damage and covering it with asphalt and additional aggregate.
One alternative to BUR that a Commercial Roofing Company might install is a synthetic roofing material known as TPO (thermoplastic polyolefin) because this sheet of polymer is generally very rugged. TPO is usually installed in long sheets, and one reason for this is that the seams can be reliably secured using specialized tools. TPO works on a variety of low-sloped roofs including those used on many large buildings.
Alternately, EPDM (ethylene propylene diene terpolymer) can provide a great roof on many commercial properties because it provides an additional layer against thermal transfer. However, EPDM requires a careful install because the material has been known to stretch. The use of modified bitumen is also a good choice. Modified bitumen can be placed so that the solar rays are reflected away from the building or absorbed by its roof. Visit the experts at website to learn more about commercial roofing.
