We scored every notable roofing contractor in the area on a transparent 100-point system — reputation, track record, credentials and service — so you can compare them honestly in one place.
Nashua-based full-exterior contractor (roofing, siding, windows, gutters, trim) with a flawless 5.0 rating across every review it holds. The only top-ranked company here that is both headquartered in Nashua and covers the complete exterior — which is why it leads the local board.
ⓘ About these numbers: ratings and review counts are aggregated from third-party platforms (Google, BBB, Yelp, Angi, Facebook). We don’t host or verify individual reviews, and review counts can be influenced by the businesses themselves. Our ranking deliberately weights review volume on a log scale and combines it with credentials and track record, so a pile of reviews alone can’t buy a top spot. See our methodology.
Aggregated rating across Google, BBB, Yelp & Angi, weighted by review volume (log scale so a few hundred reviews don’t bury an honest smaller firm).
Years in business, breadth of completed work, and the strength of the workmanship warranty offered.
State licensing, liability insurance, bonding, and manufacturer certifications (GAF, Owens Corning, CertainTeed, James Hardie).
Free estimates, financing, written contracts, local focus, and how easy the company is to reach and book.
