GAF LayerLock® Technology
Enhanced Shingle Installation and Wind Protection
GAF's patented LayerLock® Technology is designed to improve the strength and installation performance of its qualifying Timberline® shingles. This innovative technology mechanically fuses the overlapping layers of the shingle together, creating a stronger bond and allowing for the industry's widest nailing area, known as the StrikeZone®. The larger, clearly marked nailing area helps roofing professionals achieve more accurate nail placement during installation, supporting a more secure and consistent roofing system.
For homeowners in Central Indiana, proper shingle installation is especially important when protecting a home against strong winds and changing weather conditions. LayerLock® Technology works alongside GAF's Dura Grip™ Adhesive to create a strong shingle-to-shingle bond that helps reduce the risk of shingle blow-offs. When installed with the required qualifying GAF roofing accessories, eligible shingles may also qualify for GAF's WindProven™ Limited Wind Warranty, which offers wind coverage without a maximum wind speed limitation, subject to warranty terms and conditions. At TJD Roofing & Exteriors, we believe choosing quality roofing materials and proper installation practices makes a difference in protecting your home for years to come

GAF Weather Stopper® Lifetime Roofing System Warranty
The GAF Weather Stopper® Roofing System is designed to provide homeowners with added confidence through a complete roofing system backed by manufacturer warranty protection. When qualifying GAF Lifetime Shingles are installed with the required GAF accessories by an eligible contractor, homeowners may qualify for enhanced warranty coverage that protects against manufacturing defects and includes coverage for qualifying roofing components.
Choosing a qualifying GAF roofing system through TJD Roofing & Exteriors gives homeowners access to warranty options designed to provide long-term protection and added peace of mind. Actual coverage depends on the products installed, contractor eligibility, and applicable GAF warranty terms and conditions.
