Peter DeSalvo started this company in the fall of 2010, at age 20, with $2,500 after being laid off from a general contractor. Fifteen years later, his Hudson, NH roofing and exteriors company has grown into an operation with several named project managers running jobs across New Hampshire and Massachusetts. Speed and directness are the two things reviewers keep coming back to. One homeowner compared five roofing companies and said the first four sent salesmen who quoted astronomical prices after two-hour slideshow pitches; DeSalvo, by contrast, gave a straightforward assessment and got a 2,000-square-foot roof done in a day and a half. Multiple reviewers describe full roof replacements finished in a single day, even in 90-degree heat or on short notice before winter. When a tree crashed through one customer's roof, through the attic, and into a newborn's room in 2023, James from DeSalvo came out the next day, was upfront about the damage, and explained repair-versus-replacement options rather than pushing the more expensive one. The company also does commercial work: a property manager for a townhouse complex has used the team repeatedly for vent replacements and roof patching. In an April 2026 review, one customer, describing themselves as a licensed real estate broker since 1988, said the company's practices were deceptive and among the most unethical they'd encountered doing business, a sharply different account than the dozens of reviews around it, which are uniformly positive both before and after. Peter DeSalvo personally holds an active Massachusetts construction supervisor license, and the company's Massachusetts home improvement contractor registration is active as well. For roofing, siding, gutters or skylight work anywhere in southern New Hampshire or Massachusetts, this is a large, well-organized crew with named project managers and a strong track record on speed and communication; given the one serious complaint, it's worth getting the full scope and pricing in writing before signing.

Our roof 25 year old roof had received some repairs several year ago and I needed a current assessment done by a reputable contractor I trusted. I have had DeSalvo Contracting do a few other roofing jobs for me and I've always been impressed with the work they do. Within a couple days of my request for an inspection, Liam arrived on time. I was impress with Liam's thorough inspection, showing me areas of concern that would compromise the roof deck if not addressed. He also showed me how the existing shingles had weathered. Based on the frank discussion we had I decided to have roof redone at this time. He provided a quotation that evening. They booked me in with a date that was only a week away. The job was completed as promised and the cleanup was impeccable. Another flawless roofing job that was flawless from Liam Bowers at the start to the scheduler to the foremen and hardworking, talented workmen on the roof. I commend Peter DeSalvo for putting together such a customer oriented, highly skilled team.
