McDonald & Wetle | Roofing Services in Portland, OR 97230

Portland's damp climate makes roof deck rot and flashing corrosion frequent issues. Our approach begins with a thorough inspection to identify moisture intrusion and compromised areas. For deck rot, we perform precise repairs or targeted replacement of affected sections to restore structural integrity. For flashing corrosion, we remove the damaged material and install new, durable flashing using high-quality metals and proper sealing techniques. Our moisture control and waterproofing services are specifically designed to prevent these problems from recurring, ensuring your commercial roof is resilient against the local weather.

We install a variety of commercial roofing systems tailored to your building's needs and performance goals. Our expertise includes traditional built-up roofing (BUR), durable single-ply membranes like TPO and EPDM, and long-lasting slate tile systems. We also specialize in integrating solar roofing and eco-green roof systems that can improve energy efficiency and sustainability. Since 1921, we've helped Portland-area businesses select and install the right roof for longevity, weather resistance, and value.

Yes, proactive maintenance is key to maximizing your roof's lifespan and preventing costly repairs. Our maintenance services include regular inspections, cleaning of drains and gutters, and prompt repair of minor issues like small leaks or seam separations before they worsen. For roofs with waterproofing or moisture control systems, we check seals and membranes for integrity. A tailored maintenance plan from our team helps protect your investment and is a core part of our commitment to building long-term relationships with our clients.
