Spokane winters bring heavy snow followed by freeze-thaw cycles that push water under shingles and flashings on homes built from the 1940s through the 1980s. Maintenance visits focus on clearing debris from valleys and checking step flashing around chimneys before the first heavy snow. Homeowners in the South Hill and Browne's Addition often see granule loss on south-facing slopes after summer heat and wind storms.
Asphalt shingles remain the dominant material here, but many roofs also have older cedar shakes that need annual moss treatment to avoid rot. We inspect attic ventilation because poor airflow turns minor leaks into ceiling stains once temperatures drop below freezing. Checking sealant around skylights and pipe boots now prevents emergency calls when ice dams form along the eaves.
Terrain matters in Spokane County. Steeper lots on the lower South Hill collect drifting snow against one side of the roof, so we pay extra attention to those edges. Flat sections over additions are checked for ponding that leads to membrane failure after repeated freeze cycles.
Technician insight
In Spokane the thing that catches most people out with roof maintenance is waiting until November to check for ice dam risk. Homes on the South Hill with south-facing slopes lose granules every summer, then the first big snow pushes water under the remaining shingles because the flashing was never resealed.
South Hill Ice Dam Prevention
A 1970s split-level showed water stains along the north eaves after early snow. We found clogged gutters and failed sealant at the valley. After clearing debris and renewing the flashing, the homeowner avoided interior damage during the January freeze.
