One of the most common roofing methods in use on commercial buildings is the low-sloped roof, sometimes known as a flat roof. There are a variety of methods and materials for covering this type of roof including TPO (thermoplastic polyolefin), EPDM (ethylene propylene diene terpolymer) and BUR (built-up roofing). A qualified Flat Roofing Contractor in Topeka KS should be able to install, inspect and repair any of these roofing materials. Of course, each type of flat roofing works best in specific circumstances, but the most commonly used roofing system is BUR.
BUR is a combination of asphalt placed over layers of a water resistant membrane such as roofing felt. The roof is built in stages with the initial membrane being placed over some type of decking, typically OSB (oriented strand board) or plywood, although metal may also be used. Each layer of the membrane is thoroughly coated with asphalt so that all seams and any roofing details are completely sealed. The initial number of layers is typically three, but the maximum will depend on the strength of the roof and its supporting structure. One reason for this is that the BUR system uses a ballast to secure the roof properly.
TPO is an excellent alternative to BUR. However, installing TPO roofing may require some changes to the roof. This polymer is placed in long sheets, and one reason for this is the use of automated welders to seal each seam. Strong welds reduce the chance of weak seams. One of the benefits of TPO is extreme durability. The polymer stands up well to long-term weather exposure and is reasonably easy to repair. A trained Flat Roofing Contractor in Topeka KS should be able to patch most damage by hand welding.
EPDM is a synthetic rubber that can be used on larger buildings. One reason for its popularity is that it comes in different colors. An EPDM roof with a white surface is a great way to reflect solar rays and reduce heat inside the building. Less heat accumulation results in lower utility fees. However, EPDM is a little harder to install and repair than either TPO or BUR. Contact us for more information about flat roofing installation or repair.
