Roof Replacement in Washington: Local Market Insights
Washington experiences a mild marine climate west of the Cascades with wet, cool winters and dry summers, shifting to a cold semi-arid continental climate east of the mountains in the Columbia Basin and Palouse. Persistent rain from October through May compresses exterior windows west of the crest, while Spokane and eastern Washington face real snow and freeze loads. For roof replacement projects specifically, this means timing and material selection are key factors in both cost and quality.
The competitive housing market in this state keeps contractor demand (and prices) elevated year-round.
