Roof Flashing & Valley Repair – Kennesaw, GA
This roof repair in Kennesaw, GA restored critical protection to the home by addressing damaged shingles, compromised valley materials, and failing flashing around roof penetrations and the chimney. The project improved weather resistance and reinforced high-risk areas while preserving the integrity of the existing roofing system.
Project Overview
The homeowner reported concerns related to water intrusion and deteriorated roofing components around the plumbing vent, valley, and chimney areas. An inspection confirmed damaged shingles, worn flashing, and vulnerable valley protection that required immediate attention to prevent further moisture intrusion.
The approved scope of work included removing and replacing shingles and the plumbing vent boot, installing new ice and water shield and shingles along the valley, and replacing chimney flashing. Siding was cut back per code requirements to allow proper flashing installation, with repairs focused solely on the roofing system and roof-to-wall transitions.
Results
The completed repairs restored proper waterproofing and protection at some of the roof’s most vulnerable areas. New GAF Timberline HDZ shingles in Slate blended seamlessly with the existing roof, maintaining curb appeal while ensuring durable coverage. Reinforced valley protection, updated flashing, and a new plumbing boot significantly reduced the risk of future leaks, leaving the homeowner with a more secure and reliable roofing system designed to withstand local weather conditions.
