HDZ System Upgrade | Lawrenceville
This roof replacement in Lawrenceville, GA restored full protection to the home using GAF Timberline HDZ shingles in Weathered Wood. 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 storm exposure and age-related wear, the homeowner noticed declining roof performance, including compromised shingles, vulnerable flashing areas, and ventilation concerns. An inspection confirmed the need for a full roof replacement, along with upgraded leak protection and ventilation improvements. The home’s aging roof system no longer provided dependable defense against Lawrenceville’s frequent rain 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. Additional leak barriers were installed at valleys, penetrations, and chimney areas to reinforce moisture protection. Existing box vents were removed and replaced with a continuous ridge vent system to improve attic ventilation and airflow. Flashing components were upgraded at walls, chimneys, and roof transitions, and decking repairs were completed as needed to ensure a solid nailing surface. With installation completed to manufacturer standards, the homeowner now has a secure roofing system built to perform through future storms.
