Derek Cook's Roofing Specialists, INC.

Derek Cook's Roofing Specialists is a Manchester-area New Hampshire roofing company that homeowners across Hillsborough and Rockingham counties call for full roof replacements, storm and leak repairs, skylights and gutters. It is BBB accredited with an A+ grade, and the reviews that carry the company's reputation almost all name the owner, Derek, personally. The consistent theme across nearly 150 reviews is speed with care. Homeowners describe crews stripping and re-shingling a whole house in a single day — a 2025 reviewer in Goffstown described the assessing, quoting, prepping, installing and cleaning up as looking easy, and a July 2025 reviewer said the whole job was completed in one day. Cleanup comes up again and again, from tarped garden beds to yards scoured for nails. Communication is the second pattern. A January 2024 reviewer emailed on Christmas Day and got a call back the next morning; an October 2021 reviewer said phone calls were returned promptly and the quote was accurate; a February 2026 reviewer called in a panic over ice-dam leaks and had the crew show up promptly. Skylight installation and gutter work show up alongside roofing often enough to be real second lines, and the company also appears on jobs covering windows, siding and decks. Price is where the record is not unanimous, and it is what to ask about. A September 2024 one-star reviewer said the company came in more than $3,000 above every other bid and would not put an explanation in writing; a Reddit commenter in 2023 said they were the second most expensive quote and tried to package in an additional structure after being told no. Other reviewers who were not given the cheapest quote said the work was worth it anyway — a March 2025 reviewer went with a friend's recommendation over a lower bid and said it was totally worth it. If you want a roof replaced fast by a crew that cleans up behind itself, this is a strong shortlist candidate. Get the full scope and price in writing before you sign, ask what exactly is included beyond the roof itself, and compare at least one other bid — that is what the complaints in the record turn on. New Hampshire does not license or register roofers, so there is no state credential to check for this trade.
