Public Records Check
- Locally Regulated Maine 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 Mattra Inc.. Confirm any local permit or registration with the city or county where the work will take place.
- Registered Corporation Mattra Inc.'s registered name carries a corporate suffix (LLC or Inc), but we have not matched it to a filing on the Maine Secretary of State. You can confirm how the business is registered, and its current status, directly with the Maine Secretary of State.
- Business Address Mattra Inc.'s listed address at 68 Whipple St, Lewiston, ME 04240 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 Mattra Inc.. 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 Mattra Inc. (Google), the blended average is 4.9 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 Mattra Inc.. The more of a company's record you can check, the more informed your hiring decision.

Company Description
Mattra Inc. has served Maine homeowners for over 30 years, offering mold remediation, insulation, construction, and consulting services diagnosed and executed as interconnected systems rather than isolated problems.

Reviewers consistently report positive experiences with Mattra's service across insulation, mold remediation, and efficiency assessments. Multiple customers describe the team as professional, polite, and responsive, with several noting that work was completed on time and within quoted prices. Reviewers praise specific staff members for their knowledge and communication, and several report noticeable improvements in home comfort and energy efficiency following the work. Many customers highlight the company's attention to detail, including cleanup and follow-up quality checks. However, one reviewer reports a significantly negative experience, describing miscommunication about the scope of mold remediation work, a missed appointment without prior notice, and an unexpected requirement to sign a contract and pay a deposit to secure a rescheduled date. That reviewer also noted the crew hit a neighbor's tree and informed the homeowner only after arriving that they should not be home during work.
