Charcoal HDZ Install – Woodstock
This roof replacement in Woodstock, GA restored full protection to the home using GAF Timberline HDZ architectural shingles in Charcoal. The project improved curb appeal, strengthened weather resistance, and ensured the homeowner received a complete, manufacturer-backed roofing system designed to perform reliably in Georgia’s storm-prone climate.
Project Overview
Following significant storm activity in Woodstock, the homeowner identified widespread roof damage and aging materials that compromised the home’s ability to shed water and resist wind. A full inspection confirmed the need for a complete roof replacement to address worn shingles, ventilation deficiencies, and vulnerable flashing and valley areas. The existing roof no longer provided dependable protection against heavy rain and seasonal storms, making a comprehensive upgrade necessary.
Results
The new roofing system delivered immediate improvements in protection, ventilation, and overall performance. GAF Timberline HDZ shingles provided enhanced wind resistance, consistent coverage, and long-term durability, while upgraded underlayment, flashing, and ventilation components ensured proper moisture control and airflow. The Charcoal color refreshed the home’s exterior and complemented the existing architecture. Installed to manufacturer and code standards, the homeowner now benefits from a durable, resilient roof backed by strong warranties and improved storm readiness.
