Homes in Oregon often face one of the wettest climates in the country. With 42 inches of annual rainfall, frequent cloudy days, and long wet seasons, roofing materials must withstand constant moisture exposure. Local roofing contractors understand how Oregon’s damp, coastal environment affects shingles, flashing, and underlayment — helping you choose materials designed to prevent leaks and mold.
How Portland's Weather Impacts Your Roof
The Pacific Northwest and northern coastal regions experience unique roofing challenges due to persistent moisture and mild temperatures. Common issues include:
Moss and algae growth on shingles
Slow-developing leaks from long-term moisture exposure
Rotting or swelling of wooden roof structures
Clogged gutters due to heavy leaf fall
Wind-driven rain leaks during coastal storms
Because of the long rainy seasons, preventative maintenance is especially important for homeowners in Portland.
