Public Records Check
- Registration-Based Wisconsin 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 Wisconsin Secretary of State listed Formula, Inc. as Incorporated/Qualified/Registered when we last checked on Jul 7, 2026, registered since 2019. You can confirm it's still current with the Wisconsin Secretary of State.
- Unverified Address Formula, Inc.'s listed address at 3959 S Howell Ave, Milwaukee, WI 53207 appears to be a unconfirmed address. A roofer using a mailbox isn't necessarily a problem, but it can make the company harder to reach or hold accountable. To reach them in person, ask the contractor for a physical address or confirm one directly.
- 1 Credential Formula, Inc. holds these manufacturer certifications: CertainTeed ShingleMaster. 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 Formula, Inc. (Google, the Better Business Bureau, CertainTeed), the blended average is 4.7 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 4/5 public records for Formula, Inc.. The more of a company's record you can check, the more informed your hiring decision.
