What is the GAF Timberline HDZ shingle?
GAF Timberline HDZ® is America's most popular architectural asphalt shingle. It features LayerLock™ technology that bonds the shingle layers together, the largest StrikeZone™ nailing area on the market, and qualifies for the WindProven™ wind warranty when installed with qualifying GAF components.
Does HDZ qualify for the WindProven warranty?
Yes — when installed by a GAF Master Elite® contractor like First Light using qualifying GAF starter strips, ridge cap, and underlayment, the Timberline HDZ® qualifies for GAF's WindProven™ Limited Wind Warranty with no maximum wind speed limitation.
How is HDZ different from the older Timberline HD?
The HDZ replaced the legacy HD line and adds the LayerLock™ bond, the larger StrikeZone™ nailing area for fewer mis-nailed shingles, and qualifies for the no-maximum-wind-speed WindProven™ warranty.
