K M Mc Grath Roofing Contractors | Roofing Services in Cranford, NJ 07016

Cranford's weather cycles of heavy rain, humidity, and winter freeze-thaw can cause underlayment to deteriorate or allow moisture behind shingles. We fix this by carefully removing the affected shingles, replacing the damaged underlayment with a high-quality, water-resistant barrier, and reinstalling the roofing materials to ensure a complete seal and prevent future leaks.

First, document the damage safely from the ground for insurance. Then, call us promptly for a free inspection. We'll secure any exposed areas with temporary protection to prevent water intrusion and then perform a permanent repair, matching new shingles to your existing roof for a seamless, durable fix that stands up to our local winds.

Look for subtle signs like granules in your gutters, dents on metal fixtures, or a few missing shingles after high winds. Inside, check attic corners for daylight or moisture stains. The best course is a professional inspection. We'll check the underlayment, flashings, and shingle adhesion—common failure points here—and give you a clear, honest assessment.
