Architectural Shingle Roof Replacement for Storm Damage in Roswell, GA

After severe wind and hail moved through Roswell, this homeowner faced significant storm damage across a large, complex roofing system with multiple elevations and steep-slope sections. The existing architectural shingles had taken enough impact to warrant a full replacement, prompting an Allstate insurance claim and a complete roofing restoration.

We completed the project with an Owens Corning architectural shingle system in Onyx Black, upgraded synthetic underlayment, enhanced ventilation, and selective repairs to decking and exterior components. The result was a bold new look paired with long-term protection designed to handle Georgia’s weather extremes.

Problem: Coordinating a Storm Claim on a Large, Multi-Elevation Roof

The homeowner’s property featured one of the larger residential roofing systems in the neighborhood, with high roof sections, steep pitches, and multiple planes that made storm damage assessment particularly involved. After the windstorm and hail event, an Allstate adjuster documented widespread shingle damage and approved a full replacement with upgraded moisture barriers and ventilation.

Beyond the shingles themselves, the roof presented coordination challenges around skylights, steep access areas, and valleys that needed enhanced ice and water protection. Five sections of roof decking also showed damage and required replacement before new materials could go down.

Solution: Full Tear-Off and Owens Corning System Installation

RoofServ began with a complete tear-off of the existing single layer of architectural shingles, followed by an inspection and replacement of damaged decking. Synthetic felt underlayment was rolled across the entire roof, with ice and water barrier applied to all valleys, low-slope transitions, and vulnerable roof junctions to guard against water infiltration.

The crew then installed Owens Corning architectural shingles in Onyx Black across all roof planes, carefully navigating the steep-slope and high-elevation sections. Ridge vent components replaced the old ventilation system to improve attic airflow and reduce heat buildup. Pipe boots, hip and ridge caps, and select gutter and downspout sections were replaced to complete the exterior restoration.

Material staging and debris management were handled with care to protect the homeowner’s landscaping and minimize disruption throughout the multi-day installation. The team coordinated around existing skylights and maintained safe access to all roof areas despite the steep pitches and height challenges.

Result: Bold Curb Appeal and Comprehensive Storm Protection

The finished roof transformed the home’s appearance with the deep Onyx Black color while delivering significantly improved weather resistance. The upgraded underlayment, ice and water barrier integration, and ridge vent system created a more resilient assembly designed to handle wind, rain, and temperature swings common in north Georgia.

With damaged decking replaced, new flashing components installed, and a professionally coordinated roof replacement completed through the insurance process, the homeowner gained both peace of mind and a roof built to perform for decades. The RoofServ Premium Warranty provides additional protection for labor-related concerns, ensuring long-term support beyond the manufacturer’s material coverage.
