GAF has announced the launch of Timberline HDZ shingles, powered by LayerLock technology. LayerLock technology mechanically fuses the common bond in Timberline HDZ shingles to offer:
- Up to 99.9 percent nailing accuracy thanks to the StrikeZone nailing area – up to 600 percent larger versus Timberline HD shingles
- Up to 30 percent faster nail fastening during installation versus Timberline HD shingles
- Dual-phase shingle-to-shingle seal with our Dura Grip sealant and StrikeZone nailing area, and an asphalt-to-asphalt monolithic bond for durability and wind uplift performance
- Compatibility with Timberline HD roofing shingles
Roofing contractors can now also offer building owners a GAF WindProven limited wind warranty, a wind warranty for roofing shingles with no maximum wind speed limit, when installing GAF shingles with LayerLock technology and four qualifying GAF accessories.
