KVN Construction | Roofing Services in Portland, OR 97266

Portland's weather makes proper roof ventilation and gutter capacity critical to prevent moisture damage and ice dams. Our approach starts with a thorough inspection of your existing system. For ventilation, we assess and correct issues like blocked soffits or inadequate ridge vents to ensure balanced airflow that protects your roof deck and regulates attic temperature. For gutters, we calculate the correct size and pitch for your roof's surface area and install systems, including downspouts and extensions, that effectively manage our region's heavy rain, directing water safely away from your foundation. As a Malarkey-certified roofer, we use quality materials and proven techniques tailored to our local climate.

Our reroofing service is a comprehensive process. We begin with a full inspection and tear-off of the old roofing materials down to the decking. We then repair any damaged wood, install new underlayment for an added moisture barrier, and expertly install your new Malarkey roofing system. Protection comes from a dual-warranty approach. You receive the manufacturer's warranty on the materials for long-term coverage against defects. Additionally, we back our installation with a labor warranty, giving you peace of mind that the workmanship is guaranteed. With over 22 years in Portland and over a million square feet installed, we stand behind the durability of our work.

James Hardie siding is engineered for durability, but proper installation is key to unlocking its full potential, especially in our damp climate. As one of the few local James Hardie Elite Preferred Contractors, our team is factory-trained and certified on their specific installation protocols. This ensures the siding is installed correctly to resist moisture infiltration, which is a common concern here. Our certification means we have direct access to the best materials, comprehensive product training, and the backing of the manufacturer. For you, this translates to a siding installation that not only looks great but is built to last with the highest standard of craftsmanship specifically designed for fiber cement products.
