Atlanta Full Roof Replacement
This roof replacement in Atlanta, GA restored full protection to the home using GAF Timberline HDZ shingles in Oyster Gray. The project improved curb appeal, enhanced weather resistance, and provided the homeowner with a durable, manufacturer-backed roofing system designed for long-term performance in Atlanta’s climate conditions.
Project Overview
The homeowner contacted Dr Roof after determining the existing roofing system had reached the end of its service life and was no longer providing reliable protection. A comprehensive inspection confirmed the need for a full roof replacement to address aging materials, ventilation concerns, and flashing deficiencies.
Because the project was paid out of pocket, the homeowner opted for a high-quality roofing system focused on longevity, performance, and proper installation standards. The scope included full tear-off, replacement of compromised decking, upgraded ventilation, and enhanced leak protection throughout the roof system.
Results
The new roofing system delivered immediate improvements in protection, durability, and overall performance. GAF Timberline HDZ shingles in Oyster Gray provide enhanced wind resistance, a reinforced nailing zone, and consistent coverage designed for long-term reliability.
Additional upgrades included Tri-Built synthetic underlayment, GAF StormGuard ice and water shield at valleys, penetrations, and chimneys, new drip edge at eaves and rakes, updated step and headwall flashing, and installation of Cobra III ridge ventilation. The project also included chimney cricket construction, replacement of plumbing boots, a new gooseneck exhaust vent, HVAC cap and flashing kit, and up to ten plywood decking repairs to ensure a solid roofing foundation.
With installation completed to manufacturer standards and local building codes, the homeowner now has a secure roof backed by strong product warranties and improved resilience against future weather events.
