Atlanta Dead Valley Repair

This roof repair in Atlanta, GA restored localized protection to the home using Owens Corning Duration shingles in Estate Gray. The project addressed active leak points, dead-valley drainage issues, and ventilation deficiencies, extending the service life of the existing roof system without the need for a full replacement.


Project Overview

After signs of water intrusion and deteriorated flashing near a dead valley and siding wall, the homeowner requested an inspection to identify and correct the source of the leaks. The assessment confirmed that the issues were isolated and could be resolved through targeted repairs rather than a full roof replacement. The scope of work focused on improving drainage in the dead valley, replacing damaged shingles, correcting flashing details, and addressing ventilation concerns.


Results

The completed repairs successfully restored watertight integrity and improved overall roof performance. Damaged shingles were replaced with Owens Corning Duration shingles in Estate Gray to maintain a consistent appearance. A GAF Liberty modified bitumen system with base sheet was installed in the dead valley to promote proper drainage and prevent future water buildup.

Flashing was extended and replaced at the siding wall, counter flashing was added where needed, and exposed fasteners were sealed using 2100 sealant. Ridge vent components were repaired or replaced as necessary to improve attic airflow, and trim coil and painter’s caulk were used to create clean, durable transitions. With repairs completed to manufacturer standards, the roof now provides renewed protection against future rain events.
