About
Backed by 20 years of roofing experience and an Owens Corning Platinum Installer certification, KLAM Construction LLC serves the Portland and Happy Valley, OR metro area with roof installations spanning metal, flat membrane, and shingle systems. While the company's website skews residential, contractors of this profile in the Portland market routinely extend their flat membrane and metal roofing capabilities to commercial accounts — including multifamily housing, mixed-use developments, retail centers, small office buildings, industrial facilities, and warehouse properties where low-slope and flat roof systems such as EPDM, TPO, PVC, and modified bitumen are standard. Property managers and facility managers overseeing older Portland-area buildings will recognize the value of a crew experienced in complete tear-offs, new construction scheduling, and moisture intrusion remediation — all documented strengths of KLAM's team. The company offers 25-year workmanship warranties, a competitive pricing structure, and free estimates, giving facility managers clear budget footing before committing to a scope. Customer reviews consistently highlight KLAM's ability to mobilize additional crew to compress project timelines — a critical advantage for commercial clients managing tenant disruption or weather windows in Portland's notoriously wet climate. Their operational hours run Monday through Friday, 9 AM to 4 PM, from their Happy Valley base at 8502 SE Hinkley Ave. For building owners and general contractors in the greater Portland metro evaluating roofing subcontractors for new construction or re-roofing projects, KLAM Construction brings a verifiable track record, manufacturer-recognized installation quality, and a responsive project management approach. Reach them directly at (503) 387-6929 to discuss scope, scheduling, and warranty coverage for your next commercial roofing project.
