By GAF Timberline Shingles

Introduction GAF Timberline shingles are the shingle preferred by

many roofing contractors. One reason is the lifetime warranty GAF offers.

Choosing shingles requires homeowners to understand the pros and cons of the different lines of shingles.

About Asphalt Shingles Asphalt shingles come in two forms: architectural and

three-tab. While three-tab shingles are inexpensive, they also wear more quickly in icy and windy conditions. Therefore, the warranty is usually 30 years or less, depending on the other roofing materials used during installation. Architectural shingles are a little more expensive, but they are designed to stand up to icy and windy climates. Accordingly, many architectural shingles have warranties starting at 50 years.

Conclusion For the best results, GAF Timberline shingles should

be installed by a factory-certified contractor and need to be paired with other roofing components. They are installed over roof deck protection or a leak barrier. This weather barrier prevents moisture from reaching the underlying plywood. Ridge-cap shingles cover the area where the plywood sheets meet at the peak of the roof.
