Heavy snow loads and ice dams force water under shingles and into ceilings. Attic insulation and ventilation are the long-term fix.
High humidity feeds mold in bathrooms, attics and crawl spaces and makes air conditioners work harder to dry the air.
A long heating season puts heavy hours on furnaces and heat pumps, and cold snaps stress garage door springs and pipes.
Basements are common here, which adds seepage, sump pump and mold risk below grade.
