A1 Home Improvement

Markeese Thompson, a project manager, is named in 17 of A1 Home Improvement's reviews. The Berlin roofing and siding company says it has been in business 16 years, and it holds 4.9 stars from 717 Google ratings. The stories are about fast, tidy roof jobs. A September 2026 reviewer said a job quoted at two days was finished in one, and a June 2026 customer described new shingles on a house, a separate garage and a large outbuilding, 32 squares in all, finished with cleanup in one day. In a June 2026 review, a customer said the crew strengthened the rafters and replaced the plywood. An October 2026 Angi reviewer had the roof, siding and gutters replaced by three crews over about three weeks, and another October 2026 customer hired A1 a second time for windows on a 1938 cottage and garage. In a March 2026 review, a customer said trim that didn't look right was fixed within a few days. Three customers had trouble after the work. In an October 2026 review, a customer said they were ghosted by the salesperson once the roof was done, and were still waiting on replacement of front-yard bushes the crew ruined. A September 2026 reviewer with a tree on the house said A1 would charge an inspection fee if it was not chosen for the job. In a March 2025 review, a customer said the new roof leaked above a sliding door, that the company called it an old leak, and that particle board was used for replaced plywood.
