The GAF Master Flow Granule-Coated Aluminum Slant Back design is designed for attic ventilation. This unique finishing process allows shingle granules to be adhered directly to the vent, providing a more complementary look with the roof’s shingles. The aluminum slant back roof louver is an excellent choice against weather infiltration, especially in steep-slope applications.
