Architectural Shingle Roof Replacement
This roof replacement in Huntsville, AL restored full protection to the home using GAF Timberline HDZ shingles in Weathered Wood. The project improved weather resistance, upgraded ventilation and skylight performance, and ensured the homeowner received a durable, manufacturer-backed roofing system designed to perform in local climate conditions.
Project Overview
Following storm exposure and age-related wear, the homeowner experienced declining roof performance, including compromised shingles, aging flashing, ventilation deficiencies, and deteriorated decking. An inspection confirmed the need for a full roof replacement, along with upgraded leak protection, structural decking repairs, and replacement of outdated roof penetrations and skylights. The existing roof system no longer provided dependable defense against Huntsville’s frequent rain and seasonal storms, prompting the need for a comprehensive and long-lasting solution.
Results
The new roofing system delivered immediate improvements in protection, durability, and overall performance. GAF Timberline HDZ shingles provided enhanced wind resistance, uniform coverage, and long-term reliability. Advanced leak barriers were installed at valleys, penetrations, chimneys, and skylights to reinforce moisture protection.
Ventilation was upgraded with the installation of a full ridge vent system, along with new gooseneck exhaust vents, plumbing boots with rain collars, and a retro electrical boot. Three new Velux FCM skylights were installed with matching flashing kits to increase natural light while maintaining a watertight seal. Extensive decking repairs were completed using new OSB sheathing and dimensional lumber to ensure a solid installation surface. All flashing components were replaced and sealed to manufacturer standards. With installation completed according to best practices, the homeowner now has a secure roofing system built to perform through future storms.
