Cousins Construction | Roofing Services in Amsterdam, NY 12010

Signs include spongy areas on your roof, sagging, or interior water stains. In Amsterdam, this often starts in roof valleys or under old ice dams. Our process involves a careful inspection, safely removing shingles to assess the decking. We then replace all rotted plywood or OSB, ensure proper ventilation is in place, and install a new underlayment and roofing system to prevent a recurrence.

Roof valleys channel massive amounts of water and snowmelt. In our area, heavy snow, ice, and debris can compromise the valley flashing. We fix leaks by removing the old material, installing new, high-grade metal valley flashing (like galvanized steel or copper), and integrating it seamlessly with new shingles or siding. For a lasting repair, we often recommend addressing the entire valley section rather than a temporary patch.

Absolutely. As a full-service exterior contractor, we frequently coordinate roof and siding replacements for Amsterdam homes. This approach ensures critical flashings where the roof meets the siding walls are integrated perfectly, eliminating a major potential leak point. It also improves project efficiency, protects your home during the process, and gives you a unified, updated exterior look with enhanced weather protection.
