Portland receives over 40 inches of rain annually, with the wettest months from November through March creating sustained pressure on commercial roof drainage systems and perimeter waterproofing. Many commercial buildings in the Pearl District, Old Town Chinatown, and Central Eastside Industrial District date to the early 1900s and feature brick construction with outdated plumbing and inadequate foundation drainage. When a cast iron drain line fails or a flat roof membrane develops leaks, water intrusion happens quickly and affects large areas. Business interruption mitigation requires understanding how water moves through these older structures and deploying enough drying capacity to handle thousands of square feet of saturation before mold growth begins within 48 hours.
