Public Records Check

  • Locally Regulated New Hampshire 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 Cahill Roofing Incorporated. Confirm any local permit or registration with the city or county where the work will take place.
  • Registered Corporation The New Hampshire Secretary of State listed Cahill Roofing Incorporated as Active when we last checked on Jul 8, 2026, registered since 1998. You can confirm it's still current with the New Hampshire Secretary of State.
  • Residential Address Cahill Roofing Incorporated's listed address at 329 Broad St, Nashua, NH 03049 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 Cahill Roofing Incorporated. 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 Cahill Roofing Incorporated (Google, Yelp, the Better Business Bureau), the blended average is 4.5 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.

About this review summary

This summary was automatically generated from customer reviews that were publicly visible at the time it was created on one or more of the review aggregators listed below. It does not constitute a review, rating, endorsement, or statement of fact about the business - it reflects only the opinions expressed by those reviewers as found at that time, not the views or conclusions of RooferWatch. Automated summaries can contain errors or omit context and may become outdated as new reviews are posted, so please read the original reviews through the links provided and do your own due diligence. If you are the business owner and believe anything here is inaccurate, submit a correction and we’ll review it promptly.
  • Avg. Rating 4.5
  • BBB A+
  • Google 4.9
  • Yelp 3.7

Reviewers report mixed experiences with Cahill Roofing. One customer describes positive experiences with both emergency repairs and a full roof replacement, praising the company's responsiveness, willingness to accommodate last-minute changes, professional crew, and clean workmanship. Another reviewer reports satisfaction with roof options, materials, attention to detail, and competitive pricing. However, a third reviewer expresses significant dissatisfaction, stating that after a roof installation 19 years ago, subsequent leak issues arose. This reviewer reports that the owner was defensive, denied problems existed, and refused to discuss independent findings showing installation defects in the cricket box and flashing around a chimney. The reviewer states the owner declined to repair the work, and another contractor subsequently completed repairs that resolved the water intrusion.

About this average rating

This figure is a straightforward average of the public ratings we’ve gathered for this company across the following review platforms that our systems have identified: Google, Yelp, the Better Business Bureau. It is not a proprietary RooferWatch score or a judgement of our own; each source is converted to a common five-star scale and blended into a single number so that no one platform’s reviews carry outsized weight, giving a more balanced read on overall sentiment. We’d still encourage you to read the underlying reviews on each platform and weigh them for yourself.

They simply describe patterns in those reviews - how often new reviews appear, how often the owner replies, and whether recent star ratings run higher or lower than older ones.
