Slateline designer shingles have become a popular choice for homeowners and home remodeling/rebuilding professionals alike due in no small part to their ability to beautify and protect. The shingle’s highly defined shadow lines and gently tapered cut out sections take on the appearance of more expensive slate shingles. The durable Slateline shingles from GAF utilize the patented Dura Grip system that affixes the shingles to the roof and keeps them there, even during 130 mph winds. This quality has allowed GAF to include a limited lifetime warranty with Slateline shingles, giving homeowners a peace of mind that is seldom found with other shingles from other companies. Slateline shingles also come with a Class A fire-resistance rating from Underwriters Laboratories. It is the highest rating awarded by UL and it is higher than the rating give to many plastic/synthetic shingles or wood shakes, most of which only earn a Class C fire resistant rating.
