There are several ways to repair a leaking roof and, sometimes, the method of repair varies with the type of roof installed. For example, a damaged roof may need a simple patch to stop a leak, or it may require patching and a polymer coating to provide a longer useful life. A Commercial Cool Roofing Contractor Chicago can help by covering any damaged areas with a multiple-layered patch and then coating the roof. To get a cool roof, the contractor needs to use a white base or a reflective material. The purpose is to reflect excess sunlight away from the roof, which should lower the heat buildup inside the building.
Surprisingly, a Commercial Cool Roofing Contractor Chicago can cover a variety of roofing products, including metal roofing or bitumen-based roofs. The difference is in the type of coating used. For metal roofing, once all patches are in place, a two-fold layer of elastomer products is put in place using several tools, including mechanical sprayers and squeegees. The purpose is to place a smooth and consistent coating over the roof and reduce any chance of weak spots. This cuts down on leaks caused by hard winds or hail hitting the building.
There are two methods for cool coating a bitumen-based roof. The first is acrylic coatings that are used for waterproofing and the second is elastomer coatings. Acrylic coatings may be familiar to some people acquainted with manufactured housing. In this case, a cool coating is used to seal any seams between roofing sheets and to protect flashing, eaves, and other areas. The same is true when using this method on a flat roof, as only the details on the roof change.
On the other hand, elastomer roof products provide both a reflective surface and the ability to waterproof the roof. Before the coatings are applied, any necessary roof repairs should be finished. This includes securing the flashing or any vents the roof may have. These coatings will be applied differently as well. One difference is that elastomer coatings tend to need a reinforcing layer of fiberglass or polyester for strength. Click here to Get a Free Survey!
