Charcoal Architectural Roof Replacement
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 to perform in North Georgia’s variable climate conditions.
Project Overview
Following storm exposure and age-related wear, the homeowner noticed 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 upgrades. The home’s existing roof system no longer provided dependable defense against Woodstock’s frequent rain events and seasonal storms, prompting the need for a durable and long-lasting solution.
Results
The new roofing system delivered immediate improvements in protection, appearance, and overall performance. GAF Timberline HDZ shingles provided enhanced wind resistance, consistent coverage, and reliable long-term durability. Advanced leak barriers were installed at valleys, penetrations, walls, and chimney areas to reinforce moisture protection.
Ventilation was upgraded by removing the existing power fan, capping and repairing the opening, and installing a full ridge vent system to improve airflow and attic performance. New pipe boots with rain collars were installed and sealed, and HVAC vents were painted for added protection. Necessary decking repairs were completed using OSB sheathing to ensure a solid installation surface. All flashing components—including step flashing, headwall flashing, and counter flashing—were replaced and sealed to manufacturer standards. With installation completed according to best practices, the homeowner now has a secure roofing system built to perform through future storms.
