G & O Construction Contractors Inc.

G & O Construction Contractors is a Worcester roofing and general contracting company, incorporated in 2012 and run by owners Nicholas Oliveri and Peter Gariepy. Its Massachusetts Home Improvement Contractor registration, number 173679, is verified active against the state registry, which holds it in the company's own name and runs it to 2 November 2026. Alongside roofing it lists frame-to-finish construction, siding, gutters, windows, and kitchen and bathroom remodeling, and it carries an A+ grade from the BBB, where it is not an accredited member. The reviews are consistently strong — 5.0 from 20 ratings on Angi, mirrored on HomeAdvisor under the same profile — and what customers describe is unusually specific. In a 2019 review a Cambridge homeowner had four layers of asphalt shingles and five layers of rubber roofing stripped from a hundred-year-old house with extensive rot, a dormer rebuilt, a crumbling chimney rebuilt, two windows installed and the whole roof replaced; the same reviewer noted the company tarped an active leak during the winter to hold the roof until the weather allowed the full job, which none of the other bidders offered. A 2019 reviewer with a deck house described more than half of 350 tongue-and-groove ceiling boards replaced. A 2019 review covered a historic house re-roofed down to new plywood with fascia and trim replaced. Two themes recur across a decade of accounts. The first is site cleanliness: reviewer after reviewer, from 2016 through 2026, describes yards left spotless, nails picked up daily, and neighbours' fences, trees and flowers protected by purpose-built staging. The second is communication and estimating — customers name owner Nick, estimator Bob Shay, Fred, Mike and Amy in the office, and a 2026 customer said a quoted three-to-four-day roof took four days, chimney removal and cedar-shake feathering included. Several reviewers who collected three quotes said G&O came in lowest or best value. The main thing to weigh is how the record is distributed. Sixteen of the nineteen written accounts date from 2016 to 2020, with only three since 2023, and almost all of them sit on one syndicated Angi/HomeAdvisor profile — Google carries a single rating. The company's stated tenure also varies by source: its own site says more than 25 years, its Angi and HomeAdvisor profiles say 21 years of experience, and its BBB record puts the business start at 2012 and the tenure at 14 years. For a full roof replacement in Worcester County or Greater Boston — especially an old house with layered shingles, rot or chimney work — this is a registry-licensed, well-reviewed choice with a long trail of detailed accounts.
