Pewter Gray Roof Replacement | Roswell, GA
This roof replacement in Roswell, GA restored full protection to the home using GAF Timberline HDZ shingles in Pewter Gray. The project enhanced curb appeal, improved weather resistance, and ensured the homeowner received a durable, manufacturer-backed roofing system designed to meet local climate and building requirements.
Project Overview
Following storm exposure and age-related wear, the homeowner experienced declining roof performance, including worn shingles, vulnerable flashing areas, and limited ventilation efficiency. An inspection confirmed the existing roof system had reached the end of its service life and no longer provided reliable protection against Roswell’s heavy rain, wind, and seasonal storms. A full roof replacement was recommended to restore performance, address leak-prone areas, and bring the roofing system up to current manufacturer standards.
Results
The newly installed roofing system delivered immediate improvements in durability, appearance, and overall performance. GAF Timberline HDZ shingles provided enhanced wind resistance, uniform coverage, and long-term reliability. Advanced leak protection was installed at valleys, penetrations, chimneys, and other critical transition areas using StormGuard ice and water shield. New drip edge was installed along all eaves and rakes to improve water management and edge protection.
Ventilation was upgraded with the installation of a ridge vent system to promote balanced airflow and improve attic efficiency. Necessary decking repairs were completed using OSB sheathing to ensure a solid and secure installation surface. Flashing components—including step flashing, headwall flashing, pipe boots, and sealants—were replaced or reinforced to manufacturer specifications. With installation completed to industry and manufacturer standards, the homeowner now has a dependable roofing system built to withstand future weather conditions.
