Canton HDZ Roofing System Upgrade
This roof replacement in Canton, GA restored full protection to the home using GAF Timberline HDZ shingles in Pewter Gray. The project improved curb appeal, increased weather resistance, and ensured the homeowner received a durable, manufacturer-backed roofing system designed for North Georgia’s climate.
Project Overview
Following storm exposure and age-related wear, the homeowner experienced declining roof performance, including compromised shingles, aging flashing, and ventilation concerns. An inspection confirmed the need for a full roof replacement, along with upgraded leak protection, flashing improvements, and ventilation enhancements. The existing roof system no longer provided dependable protection against heavy rain and seasonal storms common to the Canton area.
Results
The newly installed roofing system delivered immediate improvements in durability, appearance, and overall performance. GAF Timberline HDZ shingles provide enhanced wind resistance, consistent coverage, and long-term reliability. Advanced leak protection was installed at valleys and key penetrations using GAF StormGuard, while flashing was addressed at walls and the chimney to improve long-term water management.
Ventilation was upgraded by removing existing vents and installing a Cobra III ridge vent system along the ridges, improving attic airflow and roof system efficiency. Decking was re-nailed and replaced where necessary to ensure a solid nailing surface. With installation completed to manufacturer standards, the homeowner now has a secure, storm-ready roofing system built to perform for years to come.
