Oregon's climate, particularly in the western part where Portland is located, is characterized by abundant rainfall and mild, wet winters. The constant moisture can lead to issues like moss growth and potential leaks if the roof is not properly maintained or installed. Summers are generally dry and pleasant, but the shift to wetter seasons demands a robust roofing system. EPDM roofing is an excellent choice for Oregon homes, especially those with flat or low-slope roofs. Its seamless, waterproof membrane is highly resistant to water penetration, making it ideal for handling prolonged periods of rain. It also holds up well to temperature fluctuations.
