Public Records Check
- Locally Regulated South Dakota doesn't issue a statewide roofing license - roofing is regulated locally through city or county permits, so there is no state license to verify. We don't count this against MJ Dalsin Roofing & Sheet Metal. Confirm any local permit or registration with the city or county where the work will take place.
- Missing Corporation Our automated search didn't find a registered business entity for MJ Dalsin Roofing & Sheet Metal with the South Dakota Secretary of State. That doesn't mean the company isn't legitimate. Many roofers operate legally as sole proprietorships, which don't require registration, and a registered business can be filed under a different name, formed in another state, or created too recently for us to match. To confirm how the business is structured, ask the contractor or search the South Dakota Secretary of State directly.
- Residential Address MJ Dalsin Roofing & Sheet Metal's listed address at 3201 West 54th Street, Sioux Falls, SD 57107 appears to be a residential address. This means the company operates from a real, locatable address rather than a mailbox or PO box, which can make it easier to reach them or resolve issues. Many roofers legitimately work from a home address, so this doesn't speak to the quality of their work, license, or insurance.
- 2 Credentials MJ Dalsin Roofing & Sheet Metal holds these manufacturer certifications: Johns Manville Pinnacle Council®, Carlisle Perfection Award. These show the company met a manufacturer's program requirements and may offer manufacturer-backed warranties, but they aren't independent quality audits. You can confirm current status with the manufacturer.
- Excellent Ratings Across the platforms we identified for MJ Dalsin Roofing & Sheet Metal (Google, the Better Business Bureau), the blended average is 5.0 out of 5, which we label Excellent. This is a plain average of public customer ratings, not a RooferWatch score. A high average reflects past customers' experiences, not a guarantee of yours, so read the underlying reviews and weigh them yourself.
