What is an ice dam?
A formation of ice that accumulates at the edge of a roof and prevents melting snow from draining off. Ice Dams are one of the most common causes of roofing damage in Colorado. The continuous expansion and contraction of melting and freezing water on your roof can destroy any type of roofing components.
what causes an ice dam?
Ice dams form when indoor heating rises through the ceiling into the attic and warms the roof surface.
How do they form?
Snow on the warmest part of the roof melts and flows down until it meets the part of the roof that is below 32 degrees. At that point, the water freezes into an ice dam.
How do ice dams lead to water damage?
Water backs up behind the dam and, as it sits on the roof, works its way under the roof covering and flows into the attic. From there it can seep through insulation, ceilings, walls and other areas where it can cause damage.
