New GAF Timberline® UHDZ™ shingles take all the great features homeowners love from their best-selling shingle, and go beyond - helping your company meet the growing demand for a premium laminate shingle.

Like their best-selling Timberline® HDZ™ Shingle, Timberline® UHDZ™ shingles now include GAF’s proprietary LayerLock® Technology and the StrikeZone® Nailing Area, which makes them easy and fast to install AND makes them eligible for the WindProven™ Limited Wind Warranty when installed with the required combination of four qualifying GAF accessories.1

With Timberline® UHDZ™ Shingles, GAF goes beyond the algae protection available on their best-selling Timberline HDZ® shingles by adding 10% MORE Time-Release Algae-Fighting capsules. That enables GAF to offer the NEW 30-year StainGuard Plus PRO™ Algae Protection limited warranty2 against blue-green algae discoloration.

All Timberline® UHDZ™ shingles now feature GAF’s patent-pending Dual Shadow Line. This technology gives the Timberline® UHDZ™ shingle a thicker, ultra-dimensional wood-shake look compared to Timberline® HDZ™ shingles. Early feedback from homeowners tells us they prefer the Dual Shadow Line look of new Timberline® UHDZ™ shingles over their best-selling Timberline HDZ® shingles.3

And finally, Timberline® UHDZ™ shingles are thicker and about 20% heavier than Timberline HDZ® shingles, putting them right in the spec for many of those big HOA opportunities.

With the launch of Timberline® UHDZ™ Shingles, GAF invites contractors to go beyond customers’ expectations — and sales goals.
