Hail Damage Roof Replacement with Owens Corning System in Johns Creek, GA

A residential property in Johns Creek, GA experienced significant hail damage following a storm event, leading to roof deterioration and a developing interior leak in a closet area. The property owner filed a claim with UNITED SERVICES AUTOMOBILE ASSOCIATION (USAA), and after inspection, a full roofing system replacement was approved to restore the home’s protection and prevent further water intrusion.

Project At-a-Glance

• Roof Size: ~35 squares (≈3,500 sq. ft.)
• Shingle Brand: Owens Corning (Onyx Black)
• Insurance Provider: USAA (UNITED SERVICES AUTOMOBILE ASSOCIATION)
• Location: Johns Creek, GA

Challenge: Hail Damage and Active Interior Leak

The primary challenge was widespread hail damage across the roofing system, compromising shingle integrity and exposing the home to moisture intrusion. The issue had progressed to an active interior leak, specifically impacting a closet space, indicating that the roofing system was no longer effectively shedding water.

In addition to storm damage, the roof featured steep slopes (10/12–12/12 pitch), which increased installation complexity and required enhanced safety measures. The aging roofing components also showed significant wear, meaning repairs were not viable and a full replacement was necessary to meet current performance and code standards.

Solution: Full Roofing System Replacement with Code-Compliant Upgrades

To address both the storm damage and long-term durability needs, a complete roofing system replacement was performed using high-quality Owens Corning materials. The solution focused on restoring structural integrity, improving ventilation, and ensuring compliance with updated building codes.

• Full tear-off and disposal of existing architectural shingles
• Installation of Owens Corning architectural shingles in Onyx Black for enhanced durability and curb appeal
• Application of synthetic underlayment for improved moisture protection
• Replacement of ridge ventilation system to maintain proper attic airflow
• Installation of new drip edge and valley metal to meet current code requirements
• Replacement of pipe boots and flashing components to prevent future leaks
• Decking replacement (5 sheets) where underlying wood was compromised
• Integration of ridge cap shingles and continuous ridge vent system for balanced ventilation

Result: Restored Protection and Long-Term Peace of Mind

The new roofing system successfully eliminated the leak issue and restored full weather protection to the home. With upgraded materials and proper ventilation, the property is now better equipped to handle future storms and temperature fluctuations.

Beyond the technical improvements, the homeowner gained renewed confidence in their home’s safety and structural integrity. The modernized roofing system also enhances curb appeal, adding visual value alongside functional performance.

Trust & Proof: Certified Materials and Insurance-Backed Scope

This project utilized Owens Corning roofing materials and included an OC Platinum Protection warranty, offering enhanced coverage and long-term reliability. The scope of work was validated through an insurance inspection and estimate, ensuring all storm-related damages were properly addressed and code-required upgrades—such as valley metal—were included.

Additionally, the documented measurements, material specifications, and approved scope provide assurance that the roofing system was installed to meet both manufacturer standards and insurance requirements.
