The roof of a building is arguably its most important asset. Unfortunately, it is often its most neglected one as well. A poorly maintained roof can leave a business vulnerable to the elements, and this could turn out to be more costly than the actual repair. Quality Roofing in Charleston, SC is not that difficult when handled by an experienced contractor. Of course, there are a variety of commercial roofing types, and this can confuse the issue. The most common method used on a commercial roof is BUR (built- up roofing), which consists of multiple layers of roofing felt and asphalt that is then topped with an aggregate such as gravel. BUR is effective and easily repaired, but it can require a lot of maintenance.
Areas, where the BUR method can fail, include flashing, edging and other roofing details. This is due to the asphalt not properly adhering to the metals and peeling away. An expert at Roofing in Charleston, SC will usually check these areas first to determine if a leak has occurred and how much damage it has caused. One concern with this type of roof is the need for reliable decking. If the decking begins to rot, then the roof can warp or buckle. This could result in even more damage and the inevitable collapse of the roof. Keeping the roof inspected should avoid these concerns.
Alternatives to the BUR system include several polymers such as TPO (thermoplastic polyolefin) and PVC (polyvinyl chloride) plus a synthetic rubber known as EPDM (ethylene propylene diene terpolymer).
Each of these materials can provide a durable roofing solution that lasts for years. One reason that the polymers work so well is that the roofing is placed in long sheets and welded with automatic tools. This creates a product that is tough and reliable. Keep in mind that the decision on which type of roof to use requires a lot of thought. Commercial roofing can be expensive and place the wrong type could be a costly mistake. Take time to consult with an expert like those employed at Powell Roofing LLC before making the final decision. This is necessary because every material has pros and cons. One example is EPDM which has a tendency to stretch a little when used incorrectly.
