Old, layered, leaking roofs are the jobs G & O Construction's customers describe. The Worcester general contractor says its main line is residential and commercial roofing, alongside siding, windows, remodeling and new construction; its site names Nick Oliveri as owner, an experienced roofer who grew up in Worcester, and claims 25 years in business. Its Massachusetts home improvement contractor registration is active. It holds 4.9 stars from 56 ratings on Google. A June 2026 customer, writing on both Google and Angi, describes a quote from Nick for tearing off the shingles, repairing leaks, removing the chimney and feathering in new cedar shake shingles; the roof was done by Wednesday after a Thursday start and a lost day to wind and rain, matching his 3-4 day estimate, and the chimney work took two more days. In a September 2025 review, a homeowner had a large rear dormer added to a 97 year old colonial with its original slate roof. A 2019 Angi reviewer in Cambridge, MA describes a home over 100 years old with 4 layers of asphalt shingles, extensive wood rot and a crumbling chimney; the crew tarped an active leak that winter, then rebuilt the chimney and a dormer and built staging to protect a neighbor's fence. Porches and renovations come up too: a 2022 reviewer had a farmer's porch added to a cape house, and a 2023 reviewer credits Peter with rescuing a whole house renovation after a bad first contractor. An August 2022 Google reviewer who never hired them says the company's drivers drive quite recklessly.

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!
