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 Ideal Roofing Co.. 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 Ideal Roofing Co. 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 Ideal Roofing Co.'s listed address at 3311 Idlewood St, North Sioux City, SD 51104 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.
- 0 Credentials Our automated search didn't find a manufacturer certification for Ideal Roofing Co.. 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.
- Excellent Ratings Across the platforms we identified for Ideal Roofing Co. (Google), 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.
We verified 3/5 public records for Ideal Roofing Co.. The more of a company's record you can check, the more informed your hiring decision.
