Why This Roof Failed - What It Took To Fix It

This roof on Harrigan Avenue had reached the end of its service life. The original shingles were brittle, the plywood along the perimeter showed signs of moisture weakening, and the old gutter system couldn’t keep up with rainfall, causing overflow and staining along the fascia. Once we opened the roof, it was clear that years of poor ventilation and water intrusion had softened several sections of the decking.

To restore the home properly, our team replaced compromised plywood, installed a modern GAF shingle system with improved ventilation, and upgraded the gutters to a 6″ seamless setup with 3″×4″ leaders. With the addition of new gutter guards, the entire system now performs better, drains more efficiently, and protects the home from future water problems.
