Owens Corning Roof Replacement for Wind and Hail Damage in Alpharetta, GA

Allstate documented the damage, and the insurance claim was approved for a full roof replacement with ventilation and flashing upgrades. The project restored the home’s protection while improving performance for years to come.

Problem: Storm Damage Across Multiple Roof Elevations

The homeowner contacted their insurance company after noticing damaged shingles and vents following a major storm. Allstate’s adjuster confirmed widespread wind and hail damage across the entire roof, including cracked shingles, compromised ridge caps, and damaged pipe flashings. The roof’s multiple elevations and steep-slope sections meant the damage extended across several distinct areas of the home.

Beyond the visible shingle damage, the insurance scope identified aging box vents that needed replacing, outdated pipe boots, missing drip edge, and deteriorated flashing around roof penetrations. Three sections of decking showed water intrusion and required replacement. The homeowner needed a full roof replacement to restore reliable protection and prevent future leaks.

Solution: Insurance-Approved Roof System Upgrade

RoofServ worked directly with the homeowner and Allstate to execute a complete roof replacement that addressed every item in the insurance scope. The existing architectural shingles were removed, and the roof deck was inspected. Three sheets of damaged decking were replaced to provide a solid foundation for the new system.

The team installed Owens Corning architectural shingles in Onyx Black over synthetic felt underlayment, delivering improved moisture resistance. The old box vents were removed and replaced with a continuous ridge vent system that provides better attic airflow and temperature regulation. Black drip edge was installed along all eaves and rakes to protect the fascia and direct water away from the home.

All three pipe boot flashings were replaced with new rubber boots designed to seal tightly around vent pipes. Eight metal turtle vents were swapped out for new units, and damaged downspout sections were replaced to ensure proper drainage. The crew protected landscaping throughout the installation and completed a thorough cleanup and final inspection before the project wrapped.

Result: A Storm-Ready Roof with Improved Ventilation

The completed roof now provides reliable protection against wind, hail, and water intrusion. The upgraded ridge vent system improves attic ventilation, reducing heat buildup in summer and moisture problems in winter. Fresh flashing, new pipe boots, and quality drip edge work together to keep water out and extend the life of the roof.

The homeowner gained peace of mind knowing their roof is built to withstand Georgia’s unpredictable weather. The Onyx Black shingles deliver a clean, modern look that enhances curb appeal, and the RoofServ Premium Warranty covers labor for five years, protecting the investment for the long haul.
