Metal Roof Coatings Purpose and Application
Roofing contractors apply the coatings as a liquid like paint and the covering measures from paint film thickness (3 dry mils) to up 40 dry mils. The contractors apply a protective coating over metal roofs. Do not use metal roof coatings to cover asphalt roofs because it inhibits normal shingle drying leads to moisture related problems.
