EPDM (ethylene propylene diene terpolymer) roofing is a robust single-ply membrane ideal for Oregon's frequently wet and sometimes hot conditions. Its seamless application and resistance to UV radiation are particularly beneficial for homes in the Portland area and beyond, where consistent moisture and sun exposure can affect roof integrity. The installation process we follow is designed to create a watertight seal that can withstand Oregon's significant rainfall. We begin by preparing your existing roof deck, ensuring it is clean, dry, and structurally sound. The EPDM membrane is then carefully laid out and secured using either adhesives, mechanical fasteners, or a ballasted system, depending on the roof's slope and design. All seams and edges are meticulously sealed to prevent water penetration, a critical step for longevity in Oregon's climate. Flashing around penetrations like vents and chimneys is also installed with precision.
Common questions
How much does it cost to have a roof installed in Oregon?

What are the steps to installing an EPDM roof?
Our EPDM installation process starts with a thorough inspection and surface preparation. The EPDM membrane is then applied using an appropriate method: fully adhered, mechanically fastened, or ballasted. We meticulously seal all seams and edges to ensure a watertight barrier and install necessary flashing around any roof penetrations. This ensures a durable finish.
What is the cheapest type of roof to install in Oregon?
For sloped roofs, asphalt shingles often present a lower upfront cost in Oregon. However, for flat or low-slope applications common in some Oregon regions, EPDM offers a cost-effective and durable solution. Its longevity can lead to lower overall costs over the roof's lifespan, especially in areas with frequent rain. Let us provide a quote.
What is the 25% rule for roofing?
The 25% rule in roofing often pertains to the amount of damaged material that can be repaired versus requiring a full replacement. For EPDM, our focus is on complete, seamless installation to prevent leaks. We assess your specific roof situation to determine the best approach for a long-lasting EPDM system.
What is the average cost to have a new roof in Oregon?
The average cost for a new roof in Oregon is influenced by material choice, roof size, and installation difficulty. EPDM is a popular choice for flat or low-slope roofs in Oregon due to its durability against the region's rainfall. Contact us for a personalized quote for your property.
