Proper attic insulation and ventilation are key. We inspect your attic to ensure it's adequately insulated to minimize heat loss, which melts snow unevenly. We also check that soffit and ridge vents are clear to allow cold air to circulate, keeping the roof deck uniformly cold and preventing the freeze-thaw cycle that causes ice dams.

Signs often appear inside your home. Look for water stains or drips along exterior walls or in the attic, especially after a thaw. From the outside, you might see damaged or missing shingles. We recommend a professional inspection, as trapped water can rot sheathing and compromise the roof structure long before it becomes visibly apparent inside.

Not necessarily. For localized damage from ice dams, we can often perform a targeted repair. This involves removing the affected shingles, replacing the compromised underlayment and any rotted decking, and reinstalling new shingles to seamlessly match your existing roof. We'll provide an honest assessment of whether a repair or full replacement is the most cost-effective, long-term solution for your Winthrop home.
