Portland receives 43 inches of annual rainfall, with 75% concentrated between October and April. This extended wet season stresses aging commercial roofs and exposes drainage system inadequacies. Many Pearl District and Northwest Portland buildings constructed during the 1980s warehouse conversion boom lack modern waterproofing, making them vulnerable to water intrusion during sustained rain events. Add the Cascadia Subduction Zone threat, and Portland facilities face potential simultaneous pipe ruptures across entire buildings when seismic activity strikes. Pre-loss planning becomes essential when your commercial property faces both chronic seasonal threats and catastrophic seismic risk.
