A leaking roof can turn into a very expensive problem because damage from the water can affect the building as well as anyone or anything inside it. One way to prevent this concern is having the roof examined periodically and this is especially true with those flat or low-sloped roofs found on many commercial buildings. Flat roofs are typically created using the BUR (built up roofing) system and can get damaged when people walk over them or carry equipment across them. A commercial roof contractor in Charles MO can check the roof for signs of wear and patch any problems that may exist.
One of the benefits of BUR is that a new layer can be placed over the roof when simple patches are not enough. BUR uses multiple layers of a membrane like roofing felt coated with asphalt sealant as a barrier to the elements. As the roof ages, it requires additional layers to ensure everything stays dry. The initial thickness is three or four layers, but the final count will depend on the quality of the roofing joists and decking. Reliable decking is crucial because BUR uses an aggregate such as gravel as the final layer.
Other materials that a Commercial Roof Contractor in Charles MO can use include metal, TPO (thermoplastic polyolefin) and EPDM (ethylene propylene diene terpolymer). Metal roofing is a great way to protect many buildings, but it may not be the best choice for large structures. This is where polymers such as TPO excel. TPO is installed in long sheets and the edges are sealed with automated equipment. This creates a roof that is very reliable and should last for many years.
EPDM is a synthetic rubber membrane that can be used on a variety of roofing projects and it comes in several colors. A white EPDM roof is an excellent way to improve indoor comfort because the roof reflects solar rays. EPDM requires special skills, so the product is applied correctly. This is necessary because there may be some concern about shrinkage. However, a certified roofer should have no trouble with this type of installation.
