Ice dams form when heat escapes from your attic, melting snow on the upper roof, which then refreezes at the colder eaves. This ice buildup can force water under your shingles, leading to leaks and interior damage. J N B Roofing fixes this by first repairing any water-damaged decking or insulation. We then address the root cause by improving attic ventilation and insulation to prevent future ice dams, and ensure your roof's edge and valleys are properly sealed and flashed.

Yes, roof valley leaks are very common here due to heavy snow loads and seasonal temperature swings that stress these critical drainage points. J N B Roofing offers targeted repairs based on a thorough inspection. This can range from resealing or replacing damaged flashing to installing new, high-performance valley liners. We ensure the repair integrates seamlessly with your existing roof to restore proper water flow and prevent future leaks.

Prevention starts with proper attic ventilation and insulation to maintain a consistent roof temperature. We recommend a professional evaluation of your current setup. J N B Roofing can install solutions like ridge vents, soffit vents, and upgraded insulation. We also suggest regular gutter cleaning to ensure proper drainage and periodic roof inspections, especially before winter, to catch minor issues before they lead to major leaks.
