Challenge: Aging Roof System with Ventilation and Decking Concerns

The existing architectural roofing system had reached the end of its service life and required a full tear-off. With only a single layer present, removal was straightforward, but underlying concerns remained. The roof structure required careful inspection for compromised decking, and ventilation needed to be improved to meet modern performance standards.

Additionally, the property required precise coordination due to landscaping protection needs and controlled material and dumpster placement. Ensuring minimal disruption while maintaining safety and cleanliness standards added another layer of complexity.

To resolve these issues, a comprehensive roofing system replacement was performed using Owens Corning materials and installation best practices. The approach prioritized durability, ventilation efficiency, and adherence to Georgia building codes.

Key steps included:

• Full tear-off of existing shingles, underlayment, and components
• Replacement of compromised decking, including installation of new OSB where needed
• Installation of drip edge and Ice & Water Shield to meet GA code requirements
• Application of Owens Corning RhinoRoof synthetic underlayment
• Installation of Owens Corning Duration architectural shingles using a 6-nail pattern for enhanced wind resistance
• Integration of Owens Corning VentSure ridge vent system to improve attic airflow
• Replacement of flashing, pipe boots (4 units), and ventilation components
• Installation of starter shingles and ProEdge hip and ridge caps for a finished look
• Thorough cleanup, including magnetic nail sweep and gutter clearing
• Multiple quality control inspections and final walkthrough

This system was backed by a comprehensive manufacturer-supported warranty, ensuring long-term protection and performance.

Result: Enhanced Protection, Ventilation, and Long-Term Peace of Mind

The new roofing system significantly improved the home’s ability to withstand environmental stress while enhancing ventilation efficiency. With upgraded materials and proper airflow, the roof is now better equipped to regulate temperature and reduce moisture buildup in the attic.

From a homeowner perspective, the project delivered renewed confidence in the home’s protection and long-term reliability. The clean installation and attention to detail also enhanced the overall appearance of the property, adding to its curb appeal and value in Alpharetta, GA.
