In Oregon, particularly in the rain-prone Portland area, a primary concern for roofing is its ability to withstand persistent moisture and heavy rainfall. Single-ply membranes, such as EPDM and TPO, are frequently chosen for low-slope and flat roofs, common on commercial buildings and some residences. Their seamless application creates a robust barrier against water intrusion. The state's seismic activity also means that durable, well-adhered roofing systems are important for structural integrity. Proper drainage and material selection are key to preventing moss growth and water damage.
