Operating a business offers many challenges and a number of problems that must be dealt with. Luckily, some of those concerns are more easily handled than others. One of these problems could be a failing roof and prevent this issue from getting out of hand may not be as difficult as people think. There are several kinds of Commercial Roofing in Laurel MD, but the most common is the BUR (built-up roofing) system. BUR begins with the decking that supports the protective covering. There are various types of decking available such as OSB (oriented strand board), plywood or steel. The one that gets used will depend on the size of the roof and its supporting structure. Proper decking is crucial to reduce the amount of pooling that occurs with low sloped roofs.
The next layer in BUR systems is a water resistant membrane such as roofing felt or tar paper. This material is spread across the roof and slightly overlaps each preceding sheet. By starting at the base of the slope, the contractor creates a watertight layer. Next, comes a layer of asphalt that coats the roof completely. These two layers are repeated several times until the roofing is thick enough to protect the building. Typically, three to five layers are used on a new installation. Finally, the roof is covered with a ballast material to anchor it in place. This is normally an aggregate such as gravel which makes it possible to walk over the roof with minimal damage.
Alternatives for Commercial Roofing in Laurel MD include polymer sheets such as TPO (thermoplastic polyolefin) and a synthetic rubber known as EPDM (ethylene propylene diene terpolymer). TPO is a lightweight material that provides excellent service as a roof covering. Any seams are welded with automated tools to reduce the chance of failure and roofing details are sealed by hand. EPDM is generally used as a solid membrane and it comes in dark and light surface colors. It is frequently used on buildings that require a reflective roof to reduce heat concerns. EPDM also comes in a liquid form that is extremely useful in specific installations, however, it is currently produced by only one or two companies.
