Wind-Damaged Architectural Shingle Roof Replacement in Alpharetta, GA

After a severe wind event, a homeowner in Alpharetta, GA experienced roof damage that compromised the integrity of their architectural shingle roofing system. The storm created vulnerabilities that allowed moisture intrusion, which required immediate mitigation and a full roof replacement to restore long-term protection. The project was completed as part of an insurance claim with State Farm, ensuring the home was returned to a secure and weather-resistant condition.

Project At-a-Glance

• Roof Size: ~30 squares (approximately 2,964 sq ft roof surface)
• Roofing Material: Owens Corning architectural shingles
• Shingle Color: Onyx Black
• Insurance Provider: State Farm
• Location: Alpharetta, GA

Challenge: Wind Damage Compromises the Roofing System

The Alpharetta property sustained wind damage that affected the structural performance of the roofing system. The inspection and estimate documented the need for a complete tear-off and replacement of the laminated asphalt shingles across approximately 29.64 squares of roof area.

The roof also presented additional complexity due to steep slopes between 10/12 and 12/12 and a multi-story configuration, which increased safety requirements and installation difficulty. These conditions required careful planning, specialized labor considerations, and enhanced safety procedures during installation.

In addition to exterior roof damage, interior moisture intrusion had already occurred, requiring remediation and interior repair before the roofing system could be fully restored.

Solution: Installing a High-Performance Owens Corning Roofing System

To restore the home’s protection and ensure long-term performance, the damaged roofing system was fully removed and replaced with a new architectural shingle system designed for durability and ventilation performance.

Key steps included:

• Complete tear-off and disposal of the damaged laminated shingles
• Installation of Owens Corning architectural shingles in Onyx Black
• Installation of synthetic underlayment for improved moisture protection
• Addition of ridge vent ventilation to enhance attic airflow
• Installation of starter courses, ridge caps, and pipe flashing components
• Replacement of pipe boots and installation of drip edge along the roof perimeter
• Installation of ice and water barrier and valley protection in vulnerable areas
• Replacement of damaged roof decking where necessary
• Temporary roof repairs and protective measures during the project

The roofing system also incorporated upgraded ventilation through ridge vent installation, helping regulate attic temperature and improve energy efficiency for the home.

Result: A Durable and Weather-Ready Roofing System

The completed roof replacement restored the structural integrity and weather resistance of the Alpharetta home. With a new architectural shingle roofing system installed across roughly 30 squares, the property is now equipped with improved drainage, better ventilation, and stronger protection against future wind events.

Beyond the technical improvements, the homeowner gained renewed confidence knowing their home is protected by a professionally installed roofing system designed to withstand Georgia’s changing weather conditions. The combination of quality materials, careful installation, and insurance-supported restoration delivered both long-term durability and peace of mind.

Trust & Proof: Certified Materials and Insurance-Backed Restoration

This project utilized Owens Corning roofing materials backed by the Preferred Protection Warranty, providing manufacturer-supported coverage for the new roofing system.

The work followed a detailed damage assessment and insurance estimate prepared for the Alpharetta property after the wind loss event. The estimate documented the full roofing scope including tear-off, installation of laminated shingles, ridge ventilation, flashing components, and underlayment systems necessary to restore the home.

With a professionally installed roofing system and manufacturer-backed protection, the homeowner now benefits from enhanced durability, improved ventilation performance, and long-term protection against future storms.
