Most of the Lower Mainland sees little lasting snow, but homes at elevation - the North Shore, the Fraser Valley hillsides, and anywhere along the Sea-to-Sky - get real accumulation and the ice dams that come with it. An ice dam forms when heat escaping the attic melts the snow above, the meltwater runs down to the cold eave and refreezes, and the growing ridge of ice backs water up under the shingles and into the house.
We remove heavy snow loads and clear ice dams without the spikes, hatchets, and high heat that crack shingles and gouge membranes. Controlled steam and careful raking relieve the load and reopen drainage paths at the eaves and gutters, so water can escape rather than pool behind the dam and find its way inside.
Removal is the urgent fix, but the real cure is upstream. Ice dams are almost always a sign of heat loss and uneven attic temperature, so we will point you toward the ventilation and insulation improvements that stop them recurring. If you are seeing interior staining during a freeze, call early - acting before the next thaw prevents the worst of the water damage.
