Alpharetta Insurance-Approved Roof System Upgrade
This roof replacement in Alpharetta, GA restored full protection to the home using GAF Timberline HDZ shingles in Barkwood. The project improved curb appeal, enhanced weather resistance, and ensured the homeowner received a complete, insurance-approved roofing system built to meet local building codes and withstand North Georgia storm conditions.
Project Overview
Following storm activity in Alpharetta, the homeowner observed roof damage that raised concerns about the home’s ability to protect against wind-driven rain and future storms. A detailed inspection confirmed storm-related damage across the roofing system, making the home eligible for a full roof replacement through insurance.
The existing roof had reached a point where repairs would no longer provide dependable protection. To restore long-term performance and meet manufacturer and code requirements, a full replacement was recommended, including upgraded leak protection, ventilation improvements, and replacement of critical flashing and skylight components.
Results
The new roofing system delivered immediate improvements in durability, protection, and overall performance. GAF Timberline HDZ shingles in Barkwood provide enhanced wind resistance, a reinforced nailing zone, and consistent coverage designed for long-term reliability.
Additional upgrades—including GAF StormGuard leak barriers at valleys and penetrations, synthetic underlayment, new drip edge, updated flashing, ridge vent installation, and replacement of an existing skylight—further strengthened the roof’s ability to manage water and ventilation.
With installation completed to manufacturer specifications and approved through the insurance process, the homeowner now has a secure, visually updated roof backed by strong material and workmanship warranties and improved resilience for future storms.
