The Timberline HDZ shingles by GAF. GAF

GAF has introduced a new series of Timberline shingles, Timberline HDZ, which incorporates the manufacturer’s LayerLock technology to mechanically fuse the shingles’ common bonds.

The shingles create a dual-phase shingle-to-shingle seal when used with GAF’s DuraGrip sealant, as well as an asphalt-to-asphalt monolithic bond. In addition, the new StrikeZone nailing area is up to 600% larger than the nailing area of Timberline HD shingles, providing up to 99.9% nailing accuracy, according to the manufacturer, and up to 30% faster nail fastening during installation.
