Commercial Roof Coating

The biggest challenges posed by a commercial roof is its slope, or lack thereof. Many commercial buildings have flat roofs, which is a major concern for water drainage. If the water isn’t drained properly it can accumulate and cause significant water damage and problems with mold. Commercial buildings also have a larger surface area than the average home, making it more difficult to maintain over time.

Commercial materials are quite unique and not much has changed over the years in terms of procedure, but the composition of materials has evolved. In the past, commercial roofs tend to be coated with a hot tar substance that essentially adhered layers of fabric by melting it with a hot tar. These materials were generally water proof and moderately durable. However, over time this procedure has evolved to include the use of a more flexible rubber like material applied in layers. Some of the newer techniques may even apply a layer of gravel over the top to better protect the roof. The biggest advancement in commercial materials is a type of roof coating that is used to increase insulation and energy efficiency. Typically applied to the top of an existing structure using layering or even spray foam, many of these coatings can save old materials and eliminate the need for complete roof replacement.
