Acworth HDZ Roof Upgrade
This roof replacement in Acworth, GA restored full protection to the home using GAF Timberline HDZ shingles in Charcoal. The project improved curb appeal, increased weather resistance, and delivered a durable, manufacturer-backed roofing system designed for North Georgia’s climate.
Project Overview
Following storm exposure and age-related wear, the homeowner noticed declining roof performance, including compromised shingles, vulnerable flashing areas, and ventilation concerns. An inspection confirmed the need for a full roof replacement, along with upgraded leak protection, decking repairs, and ventilation improvements. The home’s aging roof system no longer provided dependable defense against Acworth’s heavy rains and seasonal storms, prompting the need for a long-lasting solution.
Results
The new roofing system delivered immediate improvements in protection, appearance, and overall performance. GAF Timberline HDZ shingles in Charcoal provide enhanced wind resistance, consistent coverage, and long-term durability. GAF FeltBuster synthetic underlayment and GAF StormGuard ice & water shield were installed at valleys, penetrations, and chimneys to reinforce leak-prone areas.
Ventilation was upgraded by installing Cobra III ridge venting to improve balanced attic airflow. New flashing was installed at walls and chimneys, and pipe boots with rain collars were replaced to ensure proper sealing at penetrations. Rotted decking was replaced where necessary to provide a solid nailing surface and meet installation standards. With installation completed to manufacturer specifications, the homeowner now has a secure, storm-ready roofing system built to perform for years to come.
