2. 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.

3. 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.

4. 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.
