  • High-Definition Color
    Our GAF Timberline HDZ® shingles feature patented High Definition® shadow bands. These bands create exceptional depth and dimension, giving your roof a stunning high-definition look that enhances curb appeal.
  • Engineered for the Best Installation
    Timberline HDZ® shingles use LayerLock™ Technology and the StrikeZone™ nailing area. Each of these advancements helps ensure precise installation. In tests, roofers achieved up to 99.9% nailing accuracy, placing 999 out of 1,000 nails correctly. This precision translates to a robust and reliable roof for your home.
  • Advanced Algae Protection
    These high-quality shingles come with GAF's proprietary Time-Release algae protection technology. This advanced formula resists algae growth, allowing us to offer the industry-leading 25-Year StainGuard Plus™ Algae Protection Limited Warranty. With these protections in place, your roof can maintain its beauty for years to come.
  • Unmatched Wind Protection
    When installed with the required combination of four qualifying GAF accessories, your roof is protected by the WindProven™ Limited Wind Warranty. This unique feature offers no maximum wind speed limitation, providing ultimate peace of mind even in the harshest conditions.
  • Enhanced Durability
    The GAF Timberline HDZ® shingle utilizes DuraGrip Adhesive to further safeguard your roof against strong winds and wind-driven rain. Combined with LayerLock™ Technology, it ensures your shingles stay in place, offering long-lasting protection.
