This is a very common issue here. As snow melts and refreezes, it creates ice dams that block water from draining off your roof. The trapped water can then seep under shingles, finding any small crack or worn sealant. It often pools near the eaves or in valleys, leading to leaks that damage the roof deck and interior. A thorough inspection can pinpoint these vulnerable areas for repair.

Signs include sagging roof lines, spongy feeling underfoot in the attic, dark stains or mold on the underside of the roof sheathing, and persistent musty odors. In Somersworth, this often starts from undetected leaks. Fixing it requires removing the damaged shingles and rotten decking, treating any underlying mold, and installing new, sturdy plywood sheathing before a proper re-roof. It's crucial to address the ventilation issue that likely contributed to the problem.

Absolutely. Proactive measures are key in our climate. We recommend ensuring your attic has adequate insulation and ventilation to keep the roof deck cold and prevent ice dams. Regular gutter cleaning and installing waterproof underlayment at the eaves (ice and water shield) are also highly effective. A pre-winter inspection can identify potential weak spots before the heavy snow arrives.
