The roof on a commercial building is one of its most useful features. Not only does it supply the building with additional strength, but it covers the structure so that rain is easily shed. This can be important when the weather in Oahu turns ugly. Roofing Contractors in Oahu can provide a number of options when installing or replacing a commercial roof such as BUR (built up roofing), TPO (thermoplastic polyolefin) sheets or steel panels. Of course, the kind of material used on the roof will depend on its construction type. Most large buildings make use of the low-sloped or flat roof because it tends to be easier to install.
Historically BUR has been the most common option with low-sloped roofs and there are several reasons for this. First, the roof is budget friendly. This is mostly because it uses low-cost materials such as roofing felt and hot asphalt. Second, BUR is easily repaired. Most small damage can be handled with a simple patch. If the roof is getting a little old or has multiple issues, then it may be possible to cover it with an additional layer of membrane and asphalt. One concern with BUR is that it needs regular inspections so that unexpected leaks do not occur.
Roofing Contractors in Oahu can replace a BUR system with polymer sheets such as TPO or PVC (polyvinyl chloride). TPO is the preferred choice because it is very reliable. Plus, TPO sheets are welded with automated equipment and this provides a reliable seal. TPO roofs tend to need fewer repairs than BUR ones and the repairs are typically easy to make. However, a torn sheet may require the replacement of large portions of the material, which could cost a bit more.
One of the more reliable options in roofing is the use of metals such as steel. Steel provides both strength and long-term protection. In fact, many steel roofs are guaranteed for decades. One reason for this is the gauge of metal being used. Another is the shape of the panels. Placing channels or angles in the steel makes each panel stronger and the use of standing seams can provide a method of protection that is difficult to beat.
