GAF Shingles have been around since the 1930s but started out in 1886 as the Standard Painting Company. That company then became Standard Rubber, which became the inventor of the first interlocking shingles in 1933. GAF is known for their “Timberline” line of shingles which makes up 30% of all asphalt shingles sold in North America. They were invented in 1967 when a RUBEROID engineer laminated two strips of shingles together to make up a much stronger shingle than was used at the time. RUBEROID and GAF merged that same year, and GAF is now one of the biggest roofing manufacturers in North America.

Types of Shingles Offered:

GAF is most popular for their Timberline shingles, but it’s not all they have to offer. They offer many different roof shingle styles, colors, and types, as well as roofing materials for both residential and commercial roofing. Some of their products include:
