Public Records Check
- Registration-Based Montana doesn't license roofing contractors; instead it requires a statewide contractor registration. We treat this check as met rather than penalise it, but we haven't independently verified this company's registration - confirm it directly with the state before hiring.
- Registered Corporation The Montana Secretary of State listed AT Klemens as Active-Good Standing when we last checked on Jul 8, 2026, registered since 2012. You can confirm it's still current with the Montana Secretary of State.
- Business Address AT Klemens's listed address at 814 12th St N, Great Falls, MT 59401 appears to be a business 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.
- 0 Credentials Our automated search didn't find a manufacturer certification for AT Klemens. Many reputable roofers aren't certified by any manufacturer, often by choice, so this isn't a sign of a problem. If a manufacturer-backed warranty matters to you, ask the contractor which certifications they carry.
- Good Ratings Across the platforms we identified for AT Klemens (Google, Yelp, the Better Business Bureau), the blended average is 4.1 out of 5, which we label Good. This is a plain average of public customer ratings, not a RooferWatch score. A solid average reflects past customers' experiences, not a guarantee of yours, so read the underlying reviews and weigh them yourself.
We verified 4/5 public records for AT Klemens. The more of a company's record you can check, the more informed your hiring decision.
