GAF Timberline HDZ Roof Replacement – Marietta, GA
This roof replacement in Marietta, GA restored full protection to the home using GAF Timberline HDZ architectural shingles in Weathered Wood. The project enhanced curb appeal, increased weather resistance, and provided the homeowner with a durable, manufacturer-backed roofing system designed to perform reliably in local climate conditions.
Project Overview
After evaluating the condition of the existing roofing system, the homeowner elected to move forward with a full roof replacement to address aging materials and ensure long-term protection. The original roof consisted of a single layer of shingles that no longer offered dependable defense against wind, rain, and seasonal weather common to the Marietta area.
The scope of work included a complete tear-off of the existing roofing materials, inspection and repair of damaged decking as needed, and installation of a new GAF roofing system built to manufacturer specifications. Advanced leak barriers, upgraded flashing, and improved ventilation were incorporated to create a comprehensive 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 long-term durability. The Weathered Wood color refreshed the home’s exterior while maintaining a classic, cohesive look. With proper underlayment installation, upgraded flashing, and ridge ventilation, the homeowner now has a secure roof system backed by strong manufacturer warranties and improved resilience for future storms.
