I've always known it's the best.
Would RecommendWhen my contractor recommended GAF Timberline shingles, there was no need to consider options. I was already aware of them and that they are considered the best shingles for a home. Now that my roof replacement is completed, I have some peace of mind as well as a warranty standing behind the product.

They look great
Would RecommendOur old roof was 20 years old, it was at the end of its product lifecycle. Our roofing contractor came in with his best shingle & best price the shingle was GAF when compared to the other 2 contractors shingles that gave us estimates, the GAF shingle was just a better looking & heavier shingle than the other 2 contractors shingles.
