Complete Roof Replacement – Woodstock, GA
This roof replacement in Woodstock, GA restored full protection to the home using GAF Timberline HDZ architectural shingles in Barkwood. The project improved curb appeal, increased weather resistance, and ensured the homeowner received a durable, manufacturer-backed roofing system built for local climate conditions.
Project Overview
Following an inspection of the existing roofing system, the homeowner elected to proceed with a full roof replacement to address aging materials and areas of reduced performance. The original roof consisted of a single layer of shingles that no longer provided dependable defense against Woodstock’s frequent rain, wind, and seasonal weather conditions.
The scope of work included a complete tear-off of the existing roofing materials, inspection and re-fastening or replacement of decking as needed, and installation of a new GAF roofing system built to manufacturer specifications. Advanced leak barriers were installed at valleys, penetrations, and chimneys, along with upgraded flashing and ridge ventilation to ensure comprehensive protection.
Results
The completed roofing system delivered immediate improvements in protection, appearance, and overall performance. GAF Timberline HDZ shingles provided enhanced wind resistance, consistent coverage, and long-term durability. The Barkwood color refreshed the home’s exterior with a warm, natural look that complements the surrounding architecture. With installation completed to manufacturer standards and enhanced ventilation and waterproofing details in place, the homeowner now has a secure roof backed by strong product warranties and improved resilience for future storms.
