There are several kinds of roofing solutions, but one of the most common methods for covering a business or other commercial building is the flat roof. Technically, a flat roof is impossible because it cannot shed water properly, which is why the so-called flat roof actually has a minor slope. Another way of thinking about this kind of roof is as a low sloped roof. The most common solution for Commercial Roofing in Grove City Ohio on a low sloped roof is BUR or built up roofing. This roofing method requires a layer of decking material with sufficient strength to support the weight of the roof. This can be either OSB (oriented strand board) or plywood.

Once the decking is in place, it will be covered with a membrane such as roofing felt or tar paper. This provides the base for the next layer which will be asphalt. Next comes two or more repeated layers of membrane and asphalt until the roofing is thick enough to provide adequate protection. After all the layers are in place, the roof will be covered with an aggregate such as gravel. The aggregate holds the roofing in place and provides a bit of traction when people need to walk over it. BUR has several benefits including a lower cost of installation and quick repairs. If the damage to the roof is severe or in multiple locations, an expert in Commercial Roofing in Grove City Ohio may be able to patch the problem and cover the roof with an additional layer or two. There is a maximum amount of possible layers, but this depends on the joist support and the type of decking in use.

Alternatives to a BUR installation include TPO (thermoplastic polyolefin) and EPDM (ethylene propylene diene terpolymer). TPO is an excellent polymer roofing option for large buildings because the seams can be sealed with automated tools. Welding the seams provides a reliable roof and TPO handles severe weather very well. EPDM is a synthetic rubber that usually comes as a solid membrane. One benefit to using EPDM is that the membrane can be coated with a reflective material to reduce the amount of heat that gets trapped inside the building. There is also a liquid EPDM coating that can be useful for sealing various types of roofs. Learn more about roofing solutions from professionals like those at Arrowroofingandsiding.com.
