Roof Replacement for Wind and Hail Damage in Marietta, GA

A homeowner in Marietta, GA required a full roofing system replacement following windstorm and hail damage covered by an Allstate insurance claim. The property’s existing architectural roof system showed signs of wear and storm impact, prompting the need for a comprehensive solution that would restore protection while upgrading performance and ventilation.

Project At-a-Glance

• Roof Size: 45 squares (approx. 4,500 sq. ft.)
• Shingle Brand: Owens Corning
• Insurer: Allstate
• City: Marietta, GA

Challenge: Storm Damage Combined with Outdated Ventilation System

The primary challenge involved addressing storm-related damage while also correcting an outdated ventilation setup. The existing roofing system utilized box vents, which limited airflow efficiency and contributed to long-term performance concerns.

Additionally, the roof structure included multiple facets, steep slopes, and a multi-level design, as illustrated in the EagleView diagram on page 3 of the insurance report. These complexities increased installation difficulty and required careful planning to ensure proper material application and safety during the tear-off and installation phases.

The project also required coordination for landscaping protection and included additional exterior improvements such as upgraded gutter and downspout systems, further increasing the scope of work.

Solution: Full System Replacement with Ventilation Upgrade and Integrated Improvements

To resolve these challenges, a complete roofing system replacement was performed using Owens Corning materials, with a focus on durability, ventilation improvement, and code-compliant installation practices.

Key steps included:

• Full tear-off of the existing architectural roofing system (1 layer)
• Replacement of compromised decking with 4 new OSB sheets
• Installation of synthetic felt underlayment for enhanced moisture protection
• Installation of Owens Corning architectural shingles in Williamsburg Grey
• Conversion from box vents to a continuous ridge vent system to improve attic airflow
• Installation of drip edge and replacement of flashing components
• Installation of 3 new pipe boots to ensure proper sealing of roof penetrations
• Integration of upgraded 6” gutter and downspout system with gutter guards
• Protection of landscaping areas, particularly near the front entry
• Final cleanup and quality control inspections to ensure a complete and professional finish

This approach ensured that both storm damage and underlying system inefficiencies were fully addressed.

Result: Improved Ventilation, Protection, and Curb Appeal

The completed project delivered a high-performance roofing system that enhances durability and long-term protection against future weather events. The upgraded ridge vent system significantly improves attic ventilation, helping regulate temperature and reduce moisture buildup.

From the homeowner’s perspective, the project restored confidence in the home’s structural integrity while also improving overall appearance. The Williamsburg Grey shingles, combined with upgraded gutters, created a cohesive and modern exterior look that adds value to the property in Marietta, GA.

Trust & Proof: Certified Materials with Long-Term Warranty Coverage

This project was completed using an Owens Corning roofing system backed by a 50-year manufacturer warranty and a 10-year workmanship warranty, ensuring reliable long-term performance.

The installation followed strict quality control procedures, including inspections and a final walkthrough to verify all components were properly installed. The inclusion of upgraded ventilation and drainage systems further demonstrates a commitment to delivering a complete, high-quality roofing solution.
