Why GAF Timberline Shingles?

Before focusing on GAF’s Timberline shingles, let’s lay out what architectural roofing shingles are.

“Architectural shingles” are another term for dimensional shingles. Dimensional shingles are asphalt shingles with two layers of material bonded together. For GAF Timberline shingles, this material is fiberglass. This double layer creates a dimensional appearance, making the shingle look more robust and creating a more interesting-looking roof.

GAF shingles are constructed with several layers of material to increase energy efficiency and longevity.

Timberline shingles build on their ultra-dimensional foundation by simulating the natural wood shake look. GAF uses a proprietary shadow band system applied to the shingles with a “feathering” technique and a randomly blended top layer. This results in a shingle with exceptional depth and dimension.

Advanced Protection

GAF Timberline Roofing series are comprised of 6 different dimensional shingle lines that feature multiple cuts and colors. Their shingles are also backed with Advanced Protection®, which means you’re getting the very best combination of weight, performance, and weatherizing that modern manufacturing technology can deliver. StainGuard® Protection helps ensure the beauty of your roof against unsightly blue-green algae.

GAF roofing material features several layers to protect your roof from the elements.
Superior Fire and Wind Resistance 

An asphalt shingle roof in the middle of high winds. Several shingles have been torn off.

This series offers the highest fire and wind protection offered for residential shingles. Each product in this series has earned a Class A UL 790 fire rating:

The UL 790 (Class A), fire rating states:

Class A roof coverings are effective against severe fire test exposures. Under such exposures, roof coverings of this class afford a high degree of fire protection to the roof deck, do not slip from position, and are not expected to produce flying brands.

These shingles also offer superior wind resistance thanks to DuraGrip™ technology, which adheres seals each shingle tightly and reduces the risk of shingle blow-off. This technology has earned shingles in the Timberline collection both ASTM D7158 Class H and ASTM D3161 Class F ratings.

The ASTM D7158 is the standard test method for wind resistance of asphalt shingles against uplift forces and is designated by class G (up to 90 mph), D (up to 120 mph), or H (up to 150 mph).

The ASTM D3161 tests interlocking shingles’ ability to resist wind. Shingles are classified as Class A when resisting wind velocity of 60 mph, Class D when resisting velocity of 90 mph and Class F when resisting wind velocity of 110 mph.
