This is a very common local issue. During winter, snow accumulates and ice dams can form at your roof's edge. As the snow melts, water seeps under shingles and into tiny cracks that expanded during freezing temperatures. When the final melt happens in spring, all that trapped water is released at once, revealing leaks. We perform specific leak detection to find these entry points and repair the compromised areas to prevent recurrence.

Signs include sagging roof lines, spongy feeling underfoot in the attic, visible dark stains or mold on the underside of the decking, and a persistent musty smell. Windsor's wet spring snowmelt, combined with summer humidity, allows moisture trapped from winter leaks to sit and rot the wood decking (the plywood/OSB layer under your shingles). Rotted decking compromises your roof's structural integrity and won't properly hold new shingles, requiring replacement before any surface repair.

Our process is designed for local problems. First, we perform a comprehensive inspection, often from inside the attic, to trace the leak's path and assess the decking condition. We don't just patch the shingle; we remove surrounding materials to expose the decking. If rot is found, we replace all affected sections to create a solid, dry base. Only then do we install new underlayment and shingles with proper sealing. This method fixes the visible leak and the hidden structural damage, giving you a lasting repair.
