Roof coatings are used over foam roofing and can also be used over other roofing materials. Heat, trapped gases, dirt, and moisture trapped in an existing membrane can cause problems for roof coatings.

The permeability rating of a roof coating is an important factor in how well a coating resists water as well. You must be careful as certain roof coatings over certain roof types can be nothing more than a bandaid and a very expensive roofing problem waiting to expose itself.

Please consider hiring Phoenix's Best Contractors to check out the condition of your roof coatings.
