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 James & Whitney Company. 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 James & Whitney Company with the Maine 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 Maine Secretary of State directly.
- Business Address James & Whitney Company's listed address at 800 Main St, South Portland, ME 04106 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.
- 5 Credentials James & Whitney Company holds these manufacturer certifications: CertainTeed ShingleMaster Premier, TAMKO Pro Diamond, FORTIFIED Roofing Contractor, Carlisle Authorized Applicator, NRCA Membership - member since 2024. 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 James & Whitney Company (Google, CertainTeed, TAMKO), the blended average is 4.8 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.

TAMKO
Reviewers consistently praise James & Whitney for responsive communication and prompt service. Several customers report that staff members like Michelle, Robert, and Rick provided quick initial contact and clear quotes. Multiple reviewers describe project managers - including Joe, Jesse, Brandon, and Sheldon - as professional, communicative, and attentive to detail. Customers report that work crews were courteous, thorough with cleanup, and completed projects on time and within budget. Several reviewers highlight follow-up service, including one customer noting the company returned at no charge to address a gutter issue years after the original project. However, one reviewer expressed significant dissatisfaction with siding work, reporting unsatisfactory results after two attempts at correction. This customer stated the quality manager indicated they were "done dealing" with the issue and offered only caulking as a solution, which the reviewer felt did not constitute proper resolution of a $60,000+ siding project.
