Charcoal Roof Replacement | Clarkston, GA

This roof replacement in Clarkston, GA restored full protection to the home using GAF Timberline HDZ architectural shingles in Charcoal. The project improved weather resistance, corrected existing drainage and ventilation issues, and provided the homeowner with a durable, manufacturer-backed roofing system designed for long-term performance.


Project Overview

Following storm exposure and prior installation concerns, the homeowner experienced declining roof performance, including compromised shingles, aging flashing, ventilation deficiencies, and improper water drainage. An inspection confirmed the need for a full roof replacement, along with upgraded leak protection, decking repairs, and ventilation improvements. The existing roof system no longer provided dependable protection against Clarkston’s frequent rain events, prompting the need for a comprehensive and long-lasting roofing solution.


Results

The new roofing system delivered immediate improvements in protection, durability, and overall performance. GAF Timberline HDZ shingles provided enhanced wind resistance, consistent coverage, and long-term reliability. Advanced leak barriers were installed at valleys, penetrations, chimneys, and wall transitions using StormGuard ice and water shield.

Ventilation was upgraded by removing the existing power fan and installing a full ridge vent system to improve airflow and attic performance. New HVAC boots, collars, and caps were installed, along with updated plumbing boots and exhaust venting. Necessary decking repairs were completed using OSB and dimensional lumber to ensure a solid substrate. All flashing components—including step flashing, headwall flashing, and counter flashing—were replaced to meet manufacturer and code requirements. With installation completed to manufacturer standards, the homeowner now has a secure roofing system built to perform through future storms.
