Lewis Drug, a long-standing retail fixture in Sioux Falls, SD, faced a serious safety issue: an aging roof hatch that lacked lift- assist mechanisms, forcing personnel to bear the full weight of the cover during access. To make matters more complex, the original hatch curb was welded directly to the roof deck, making full replacement both risky and impractical. Enter MJ Dalsin Roofing & Sheet Metal—a trusted name in the industry with decades of experience and a reputation for solving tough challenges. Partnering with MacArthur Co. and Babcock-Davis, MJ Dalsin delivered a smart, safe solution: a retrofit roof hatch that could be installed without disturbing the existing roofing membrane. The result was a clean, efficient installation that restored safe roof access while preserving the integrity of the building envelope. The MJ Dalsin team praised the fit and functionality, calling it “exactly what we needed for this project.” Alan Hintz of Lewis Drug agreed, “We love it. It’s now safe to access the roof.” This project showcases the power of expert collaboration and adaptable product design—led by MJ Dalsin’s unmatched experience in the field
