Roof coatings stand out as a fluid that is fully adhered and monolithic. It is applied to the roofing membrane and has good elastic properties. To put it simple, the material can stretch and then return to an original shape without being damaged.

The regular roof coating film will have a thickness that varies from that of paint (around 3 dry mils) to over forty dry mils. Roof coating will become the main composite roof membrane layer and the underlying system at the same time. Roof coating has to offer membrane protection and can protect the area from sunlight impact, hail, physical damage and rain.

Keep in mind that many confuse roof coatings with deck coatings. They are not the same.
