Portland receives the majority of its annual rainfall between October and May, creating prolonged periods of high exterior moisture. This extended wet season allows water to find weak points in your home's building envelope. Unlike sudden flooding events, this chronic exposure lets moisture accumulate slowly behind siding, through window frames, and around roof penetrations. By the time you see bubbling paint or lifting wallpaper, the framing, insulation, and sheathing behind it have often been wet for months. Homes in the West Hills face additional challenges from wind-driven rain, while properties near the Willamette River deal with elevated groundwater and foundation moisture. Understanding these location-specific moisture patterns is critical for proper diagnosis and permanent solutions.
