Pewter Gray Roof Replacement | Huntsville, AL
This roof replacement in Huntsville, AL restored full protection to the home using GAF Timberline Ultra HDZ shingles in Pewter Gray. The project improved curb appeal, increased weather resistance, and delivered a durable, manufacturer-backed roofing system designed to perform under Huntsville’s seasonal storms and heavy rainfall.
Project Overview
Following storm exposure and age-related wear, the homeowner experienced declining roof performance, including worn shingles, compromised flashing, and ventilation inefficiencies. An inspection confirmed the need for a full roof replacement, along with enhanced leak protection, flashing upgrades, and ventilation improvements. The existing roofing system no longer provided dependable protection, prompting the installation of a modern, code-compliant roofing solution built for long-term durability.
Results
The completed roofing system delivered immediate improvements in protection, performance, and appearance. GAF Timberline Ultra HDZ shingles provided enhanced wind resistance, uniform coverage, and long-term reliability. Advanced leak barriers were installed at valleys, penetrations, and chimney areas, while low-slope sections were reinforced using a Liberty cap sheet system for added waterproofing.
Ventilation was upgraded by removing the existing power fan and installing a ridge vent system to improve airflow and temperature regulation. New chimney flashing and a chimney cricket were constructed to redirect water and reduce long-term leak risk. With installation completed to manufacturer and local code standards, the homeowner now has a secure roofing system built to withstand future weather conditions.
