Woodstock HDZ Roof Upgrade
This roof replacement in Woodstock, GA restored full protection to the home using GAF Timberline HDZ shingles in Charcoal. 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 noticed declining roof performance, including deteriorated shingles, ventilation inefficiencies, and vulnerable flashing areas. An inspection confirmed the need for a full roof replacement along with upgraded leak protection, decking repairs, and ventilation improvements. The existing roof system no longer provided dependable defense against Woodstock’s frequent rain 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. Tri-Built synthetic underlayment and GAF StormGuard ice & water shield were installed at valleys, penetrations, and chimney areas to reinforce leak-prone locations.
Ventilation was upgraded by removing two existing box vents, detaching and resetting the power fan near the peak ridge, and installing a continuous Cobra III ridge vent system across the ridges for balanced attic airflow. Flashing was installed at walls and chimneys, pipe boots were replaced with new rain collars, and decking repairs were completed where necessary to provide 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.
