41 Harrigan Ave, Monroe Township - Roof Replacement
This project on Harrigan Avenue in Monroe Township involved a full roof replacement, plywood repairs, and a complete upgrade to a 6″ seamless gutter system with 3″×4″ leaders and new gutter guards. The home had aging decking and worn shingles that were beginning to fail, so our team rebuilt the structure properly and installed materials designed for long-term durability. It’s a great example of the kind of detailed, start-to-finish exterior work we complete throughout Monroe.

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.
