Commercial roofing is a specialized field. MJ Dalsin is simply the best contractor in South Dakota when it comes to flat rubber roofs or sheet metal maintenance and repairs. They do great work on new construction to make the building look as designed. Their sheet metal can create an amazing look for an industrial structure that even an architect would be happy with. Whether you have a warehouse, retail, or office building, I highly recommend MJ Dalsin. Reggie is the guy to talk to!

We are very happy with the work that MJ Dalsin did. Our roof was well overdue to be replaced and we were in quick need of a replacement. MJ Dalsin was quick to give us a quote and they started on the roof shortly after. Friendly staff, professional service, and we couldn't be happier with the result.

Great crew showed up promptly to deal with some leaks in an older flat roof. Also came back on short notice when a new leak was discovered. Very professional and courteous and fantastic to work with. Highly recommended

The whole experience was great! From the initial quote and review of my problem roof to the quick response for the repairs was outstanding. Great group to work with!!

These guys are the best. Free and thorough inspections. Their work is professional and quality.
