I don't know what I'm more impressed with; the customer service or the skill of the technicians. I'm in Brookings South Dakota and they are located in Sioux Fall South Dakota. The distance is roughly 50 miles. There have been times when I've called with a problem and they showed up the same day. We have one of those aging roofs with rocks on top of a membrane. MJ Dalsin has never failed to find the pin hole that is causing the leak. It's not just one technician with this talent, the whole crew is able to find the leak just by stepping it off from the inside of the building. I've kidded them before about working themselves out of a job because when they fix a leak it's for good. They even date and initial the patch. MJ Dalsin calls before they get here, contacts me when they get here, inspects the roof, shows me the pictures of the problem, tells me what they're going to do and then contacts me when it's done for my inspection and approval. Awesome is way over used but it's the best word to describe MJ Dalsin. Thank you!! Mark A. Werner

Recently had this roofing company come to the strip plaza my business is and thoroughly went over our leaky roof. Over the course of the 12 years I have been in this location these guys are the real deal. THEY KNOW ROOFING. They also stopped back in just to check and see how things were after a recent rain! Call these guys first before you waste your money somewhere else!

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.

At M.J. Dalsin, our Midwest roots date back through three generations to 1912. This foundation of experience speaks for itself in terms of our commitment to quality, innovation and customer satisfaction. It guarantees that quality service will be available for your roofing needs in the long term.

This is why we do what we do.

MJ Dalsin Roofing Company has been a great Vendor to work with in coordinating roofing repairs to many of our commercial properties within our management portfolio. We couldn’t say ‘no’ to the free estimates offered and then when we were presented with the pricing for completing preventative maintenance, it was a no-brainer of a decision to schedule the work for all of the properties. We especially appreciated the time Jared Kuik and Todd “Reggie” Hammond took in meeting with us, visiting the properties, and presenting the information in a clear and user-friendly format. Even though our work was part of an overall schedule, Mr. Hammond always made it a point to make sure any properties that started exhibiting leaks/problems, that he put guys on the roof that same day or next. Before any work started, the Dalsin crew would notify the Tenants of the building and would also inform out Maintenance Supervisor of the same. After witnessing tremendous customer care and seeing the quality of work performed, we definitely look forward to working with MJ Dalsin for many years to come.

I have worked with MJ Dalsin for the past year and half on 2 roof replacement projects and 2 roof repair jobs. The work MJ Dalsin performs is excellent and projects are completed in a timely manner with customer satisfaction always at the forefront. I have had some leaks develop in an older area of our facility and MJ Dalsin responded quickly to repair the leaks. I recommend MJ Dalsin for all roofing needs.
