Over time, GAF became synonymous with high-quality roofing products, expanding its portfolio to include advanced residential and commercial roofing solutions.

By the early 20th century, GAF had established itself as a leader in the roofing industry, offering innovative products that prioritized durability and affordability. Their commitment to innovation paved the way for their entry into asphalt shingles—a product that would become a cornerstone of their business.
