Cold Hollow Contracting | Roofing Services in Jeffersonville, VT 05464

In our area, roof valley leaks after snow melt are often caused by ice dams. As snow melts and refreezes at the eaves, it creates a dam that backs water up under the shingles, often finding its way into the valley—a critical drainage channel. This trapped water can exploit any minor weakness in the valley flashing or sealant. Our inspection focuses on identifying ice dam damage, ensuring proper valley sealing, and evaluating attic ventilation to prevent future issues.

For a persistent valley leak, a simple patch is rarely sufficient. The most effective, long-term repair involves a comprehensive approach. We carefully remove the affected shingles, inspect and replace any compromised valley flashing (often with a standing-seam metal liner for superior durability), apply new ice and water shield membrane, and re-shingle with proper integration. This method addresses the root cause, not just the symptom, and is built to withstand Vermont's heavy snow and ice.

Absolutely. Proactive maintenance is key. Before winter, we recommend a professional inspection to check for loose or damaged shingles, ensure valley flashings are sealed tight, and confirm your attic has adequate insulation and ventilation. Proper ventilation keeps your roof deck cold, minimizing the snow melt that leads to ice dams. We can also install heating cables in critical areas or apply a waterproof membrane underlayment in valleys and eaves for added protection against our harsh Jeffersonville winters.
