Coho Roofing & Contracting | Roofing Services in Anchorage, AK 99517

In Anchorage, repairing a metal roof seam leak requires a method that accounts for thermal expansion and contraction. We first clean and dry the affected seam thoroughly, then apply a high-quality, flexible sealant designed for extreme cold, followed by a durable, weatherproof tape system. This two-part approach creates a flexible, airtight seal that can withstand our temperature swings and prevent future leaks.

Preventing ice dam damage starts with improving attic insulation and ventilation to keep your roof deck uniformly cold, which stops snow from melting and refreezing at the eaves. We also install waterproofing membranes under the shingles along the roof's edge and in valleys. For existing dams, we use steam removal, which safely melts the ice without damaging your shingles or gutters.

Local experience is crucial because Anchorage's roofing issues are directly caused by our specific climate. We understand how snow load, ice dams, and temperature extremes from -20°F to 70°F affect different materials. This knowledge allows us to recommend the right repair methods and products—like cold-weather sealants and proper ventilation strategies—that will last, saving you money and repeated repairs.
