Timberline Shingles offer just the right combination of beauty, performance and reliability. Plus, Timberline now features LayerLock Technology, which powers the industry's widest nail zone and first wind warranty with no maximum wind speed limitation.

According to a survey of 380 real estate agents and certified appraisers of single-family residential homes, upgrading a roof with GAF Timberline® roofing shingles can increase the value of a home by an average of 10%. Timberline shingles are architecturally stylish, featuring GAF proprietary color blends and enhanced shadow effect for a genuine wood-shake look. StainGuard Algae Protection helps ensure the beauty of the roof against unsightly blue-green algae.

When installed with the required combination of GAF Accessories, Timberline® HDZ™ Shingles are eligible for an industry first: a wind warranty with no maximum wind speed limitation.

Timberline HDZ has a lifetime warranty with a class "A" fire rating, and a 110 mph wind warranty.

**DO NOT MIX! Note that Charcoal, Shakewood, and Petwer Gray Timberline HDZ shingles are currently being sourced from several different locations. Charcoal, Charcoal “SF” and Charcoal “MC” are all still GAF's proprietary Charcoal color blend with enhanced shadow effect, but these different color lots may vary slightly from each other. Care should be taken to source all shingles for a single job from the same color lot. Charcoal, Charcoal "MC" and Charcoal "SF" should not be mixed. Similarly, Pewter Gray should not be mixed with Pewter Gray "MC," and Shakewood should not be mixed with Shakewood "MC."
