About

In business since 1912, MJ Dalsin Roofing & Sheet Metal is one of the most tenured commercial roofing contractors serving Sioux Falls, SD and the broader region. Facility managers overseeing multi-site portfolios across the Midwest have relied on MJ Dalsin for leak repairs, new roof installations, and preventive maintenance on commercial and institutional properties — including full-service hotels, restaurant franchise locations, strip plazas, and industrial structures. The company's core service lines span EPDM rubber membrane systems, built-up roofing (BUR) with aggregate surfacing, modified bitumen, metal and sheet metal fabrication, TPO membranes, and roof coatings — covering the full spectrum of flat and low-slope commercial roof systems common to office buildings, retail centers, warehouses, and institutional facilities throughout South Dakota. MJ Dalsin's documented repair process sets them apart for property managers who need accountability: crews photograph problems before and after every repair, date and initial each patch, and communicate at every stage — arrival, inspection findings, proposed scope, and completion sign-off. Reviewers managing 20-plus commercial locations in the Sioux Falls market specifically cite same-day response capability and the crew's ability to pinpoint pinhole leaks in aged membrane systems without invasive investigation. The firm also offers preventive maintenance programs and roof inspections, giving facility managers a proactive tool to extend membrane life and protect capital budgets. With a service radius that extends well beyond Sioux Falls — confirmed client engagements include Brookings, SD, roughly 50 miles out — MJ Dalsin is a viable partner for multi-site operators managing properties across South Dakota and neighboring states. Their sheet metal division also supports architectural and functional metalwork on industrial and commercial structures.
