Over the Top Roofing LLC | Roofing Services in Anchorage, AK 99507

A proper new roof installation is the first line of defense. We use high-quality, breathable underlayment and advanced sealing techniques at all penetrations to create a continuous thermal barrier. This minimizes heat escaping from your attic, which is a primary cause of ice dams in our Anchorage winters. By keeping the roof deck cold and uniform, we prevent snow melt and refreeze cycles in the valleys.

If you're experiencing recurring ice blockages in your roof valleys, it often indicates a systemic issue like inadequate insulation, poor ventilation, or an aging roof system. While repairs can patch leaks, a full replacement allows us to redesign the critical components—including upgraded ice and water shield in the valleys, proper attic ventilation, and high-R-value insulation—to solve the root cause and provide a long-term solution for your Anchorage home.

For durability against heavy snow and freeze-thaw cycles, we strongly recommend impact-resistant architectural asphalt shingles or standing seam metal roofs. Both are excellent for shedding snow. We pair these with reinforced, self-adhering ice and water shield membranes in all valleys and eaves—critical zones for ice dam formation. This combination provides the resilience and waterproofing needed to handle our local weather extremes.
