GAF MASTER ELITE® ROOFING
GAF Timberline HDZ® Roofing System
A coordinated approach to shingles, accessories, ventilation and warranty protection.
Timberline HDZ® Shingles
Timberline HDZ is GAF’s architectural shingle line featuring LayerLock® technology and a StrikeZone® nailing area. When LayerLock-labeled shingles are installed with the required qualifying GAF accessories, the roof may be eligible for the WindProven™ Limited Wind Warranty with no maximum wind-speed limitation.
System Components Matter
- Leak barrier at vulnerable roof areas
- Roof deck protection beneath the shingles
- Starter strip shingles at eaves and rakes
- Proper attic ventilation
- Field shingles and compatible ridge cap shingles
Algae Protection
Qualifying Timberline HDZ products bearing the StainGuard Plus™ label include a 25-year limited warranty against blue-green algae discoloration, subject to GAF terms and restrictions.
Product availability and warranty eligibility vary. Always refer to current GAF product packaging and official limited warranty documents.
