Dumags Roofing Company | Roofing Services in Sitka, AK 99835

Ice damming in roof valleys is a frequent issue here due to our heavy snowfall and freeze-thaw cycles. We perform a thorough inspection to assess the extent of the blockage and the underlying ventilation or insulation issues. Our repair process involves safely removing the ice dam, repairing any water damage to the roof deck or interior, and often installing specialized ice and water shield membranes or improved attic ventilation to prevent future occurrences.

Visible sagging along the roof ridge or in the roofline, interior ceiling dips, or new cracks in your walls are clear indicators of potential structural issues. In Sitka, this can be caused by prolonged moisture intrusion, heavy snow loads, or aging supports. We recommend a prompt professional inspection. Our team can assess the structural integrity of your framing, identify the root cause, and provide a plan for reinforcement or repair to ensure your home's safety and stability.

Our 20+ years in Sitka have given us firsthand knowledge of what materials and techniques perform best in our coastal environment. We use high-quality, weather-resistant materials specified for our region and adhere to installation methods that account for high winds and driving rain. Every project is backed by our commitment to craftsmanship and follows local building codes, ensuring your new roof is built to last and protect your home for years to come.
