Retail Asphalt Roof Replacement in Suwanee, GA with Owens Corning Shingles

A homeowner in Suwanee, Georgia contacted a roofing contractor after experiencing ongoing roof concerns, including signs of a prior leak and aging roofing materials. The property’s architectural shingle roof had reached a point where replacement was the most reliable solution to restore long-term protection and improve ventilation performance.

The project involved a full retail roof replacement using an Owens Corning asphalt shingle system. By upgrading critical components such as underlayment, ventilation, and decking where necessary, the new roofing system was designed to deliver stronger weather protection and improved airflow for the Suwanee home.

Challenge: Aging Shingles and Prior Leak Concerns

The Suwanee home’s existing architectural shingle roof showed signs of age and previous moisture intrusion. The homeowner reported a prior leak, indicating the roofing system was no longer providing consistent protection against water infiltration.

The roof’s size—approximately 44 squares—also meant that careful coordination was required during tear-off and installation to ensure every section of the roof received proper waterproofing and ventilation. In addition, the existing ventilation setup included multiple components such as box vents, ridge vents, and power fans, requiring a coordinated upgrade to maintain balanced airflow throughout the attic.

These factors made it important to replace the roofing system with a modern, integrated solution that would improve durability while addressing airflow and moisture control.

Solution: Complete Owens Corning Roofing System with Ventilation Upgrades

To provide a long-term solution, the existing roofing materials were removed and replaced with a complete Owens Corning architectural shingle system designed for durability and performance.

Key steps in the project included:

• Full tear-off of the existing architectural shingles
• Installation of upgraded underlayment for improved moisture protection
• Replacement of damaged roof decking where necessary to create a solid structural base
• Installation of Owens Corning architectural shingles in the Onyx Black color
• Installation of new pipe boot flashings to secure roof penetrations
• Installation of black drip edge along roof edges for improved water runoff
• Upgrades to the ventilation system including ridge vents, box vents, and power ventilation components

During installation, crews also took care to protect landscaping around the home and removed the existing satellite dish as part of the preparation process.

This full-system approach ensured the roof was rebuilt with modern materials and balanced ventilation designed to extend the life of the roofing structure.

Result: Durable Protection and Improved Ventilation

Following installation, the Suwanee home now benefits from a modern Owens Corning roofing system engineered for durability and consistent airflow. The upgraded underlayment and properly integrated flashing provide improved resistance against water intrusion, while the ventilation improvements help regulate attic temperatures and moisture levels.

Beyond the technical benefits, the homeowner gained peace of mind knowing their roof was replaced with a complete, professionally installed system designed to protect the home for years to come. The Onyx Black architectural shingles also refreshed the home’s exterior appearance, enhancing curb appeal while delivering reliable performance.
