Verified record
William Niland Roofing and Carpentry Services is based in Arlington, Massachusetts and lists carpentry and roof repair among its services. The profile says the business is veteran-owned, has 10 years of experience, offers emergency service, free estimates, and warranties, and lists trade license number 196837. The public review history is substantial on the platform: 75 ratings average 4.9, with two recent 2026 reviews describing same-day responses, roof-line and loose-shingle repairs, careful inspection, and fair pricing. A 2024 reviewer also described next-day service and quick roof repairs, while a 2023 reviewer said the business responded rapidly and completed a roofing project at a reasonable cost. The record is not uniformly positive. In a September 2023 review, a customer said moss remained after a treatment and was disappointed with the result and the response. That complaint is specific to the moss-removal job, so ask exactly what treatment includes, how results are expected to appear, and what follow-up is available. This looks like a practical choice for homeowners seeking responsive roof repair or carpentry work, especially when timing matters. Confirm the current license, scope, price, warranty terms, and whether the person who quotes the work will perform it.

“Repair a Flat, Foam or Single Ply Roof. Requested at 6am, he called me back and came to fix my problem by 7:30am. 5.0 Rebecca C. Woburn, MA. 1/30/2022.”
Bill answered my call for help to repair my roof immediately after I got off the computer. He came the same day to do the repair. I found him a pleasant person to work with and I am very happy the job is done and done right.
Bill repaired around my roof line, fixed and repaired loose asphalt tiles, and closed and caulked gaps to prevent any bees from entering. He even inspected other areas. He is quick and professional and for a very good price.
The day the work was done he was here 15 minutes and the moss that I wanted removed was still there. I was very disappointed.
