G&O Construction & Roofing is a Worcester, Massachusetts general contractor that self-reports 25 years in business. Its main line is residential and commercial roofing — installation, repair, inspection and skylights — alongside siding, window and door work, remodeling, new construction and accessory dwelling units across central and eastern Massachusetts. The company's site names Nick Oliveri as owner, saying he grew up in Worcester, is an experienced roofer himself, and now oversees the roofing division. Reviewers from 2012 through 2026 consistently praise the work: a 2026 review describes a roof replacement as a painless process, and a 2025 review describes a rear-dormer addition on a 97-year-old colonial that came out well. Homeowners across the years single out crew members by name — Joel, Peter, Bob Shay, Fred and others — along with administrative assistant Samantha for quick scheduling. In a 2026 Angi review, a customer said Nick, the owner, came to the house himself and gave a no-nonsense quote; in a 2024 review, another homeowner described meeting the owner directly and called him knowledgeable and community-minded. The Massachusetts Home Improvement Contractor license behind the business, number 173679, is registry-verified active. The Better Business Bureau gives the company an A+ grade and separately lists a construction supervisor license, CS-106280, issued by the Massachusetts Department of Public Safety and Inspections. Ratings are strong across platforms: Google shows a 4.9-star average from 56 ratings and HomeAdvisor shows a 5.0-star average from 20 ratings. A 2020 HomeAdvisor review names both Nick and Pete as owners, while the company's own site names only Nick Oliveri as the roofing division's owner. A 2022 review also criticized reckless driving by company vehicles, without commenting on the quality of the work itself. G&O is a fit for a Worcester-area or central and eastern Massachusetts homeowner needing a roof replacement or repair, siding, windows, or a larger remodeling or addition project, backed by a multi-year track record and a registry-verified license.

Too long: didn't read- We would hire G&O Construction again in a heartbeat. We had to have our roof replaced this year as it had a leak and was just older than anyone knew from when we bought our house two years ago. The entire process was painless and restored some of my faith in construction teams! Nick gave us a quote quickly, and the team executed to that quote flawlessly. He knows his business for sure. The quote was for removing the shingles, repairing any leaks, removing our useless chimney, repairing any holes from behind the chimney, and feathering in new cedar shake shingles so it matched the house. He estimated it would take about 3-4 days for the roof, and 2-3 days for the chimney+shingles. They started on a Thursday, and by Wednesday the roof was done, they weren't able to work that Monday due to crazy wind and rain. So exactly to Nick's quote. The final chimney removal and shingles took another two days, which was again, exactly to quote. We've had a couple rain storms since then, and no leaks. Obviously I'll update my review if something happens, but we have no reason to think that their work wasn't pristine. The entire team was friendly, professional, and did excellent work, they didn't destroy any of our property, they picked up after each day (including cigarette butts that were in the grass) and were methodical. My husband asked if he could go up on the roof with them and see what they were doing. They were so happy to show him the ropes, explaining any of his questions. There was no hostility at all over being asked about the process. He was just curious as he hasn't done roofing before. I had some questions about the project as well and when I called the office to talk to Amy, she was fantastic. She was professional, friendly, and promptly answered questions or went and found the answer and called me right back. Just a really solid company that we were happy to do business with and would hire again without any second thought.
From start to finish, G&O Construction was absolutely fantastic. Getting a quote was seamless and painless. Nick, the owner, came to our house, gave us a no-nonsense quote. When we shopped around, G&O came up comparable, but their customer service and promptness was already ahead of other companies. They started on a Thursday, and finished with the roof the following Wednesday after 1 day unable to work due to storms. Nick had quoted 3-4 days depending on layers of shingles, and they completed it in 4 days. The other part of the contract of finishing the chimney removal and feathering in new cedar shake shingles was done two days later. They were methodical, professional, the whole teams attention to detail was amazing. Our yard was left virtually spotless of any debris. When I had a couple questions I reached out to Amy in the office and she was SO helpful and nice and prompt. We would hire them again in a nano-second. HIGHLY recommend the whole group.
I had a large rear dormer placed in my attic facing my backyard on a 97 year old colonial with its original slate roof, and it came out very nice. It was a shell construction project, eventually done in the way I anticipated. I liked working with them, and they replaced all my recycled slates on the outer layer of the roof nicely. I recommend them for the beginning of any potential additions to your home. I wish to hire them again.
Met the owner and he’s an extremely knowledgeable and helpful guy. Worcester local that really cares about the community. Gave me a hot tip on how to deal with drilling holes in masonry work that’s been EXTREMELY useful.
Great job and great price!
