Roof Protect emulsifies contaminants and provides improved surface preparation and adhesion by effectively removing oil, grease, mildew, dirt, and other soils from the roofing membrane. You can also use Roof Protect annually to further protect your roof, allowing, dirt, grease etc. to be removed, further extending your roof's service life. It also contains a mildewcide to kill any mold spores on your roof.
