Verified record
Typical Greater Boston range for this kind of work, from regional averages — not a quote from Corolla Contracting Inc. Use it to sanity-check bids, then get the real number in writing.
A square is 100 sq ft of roof surface — bigger than the floor plan because of pitch and overhangs.

Corolla Contracting has been roofing out of 15 Bates Ave in Winthrop since 1989 — 37 years, four employees, and Robert Corolla's name on the door, per its BBB listing, which also carries the alternate name Corolla Roofing. The work is roofing top to bottom: commercial and residential repair and replacement, maintenance programs, tapered insulation, green roofs, and waterproofing. The thing a homeowner should weigh first is a 2019 story. NBC Boston reported that Corolla pulled the permit for the North End roof replacement where a falling metal bar critically injured a pedestrian, and that OSHA had cited the company four times over the seven years before that — about $11,400 in proposed fines, including serious fall-protection and ladder violations. BuildZoom's permit record for a Brighton job shows a stop work order issued the same day, July 25, 2019, with no resolution listed. Alongside that sits a quieter paper trail: an A+ grade on a BBB page the company has not accredited, and 75 permitted projects listed on BuildZoom. BuildZoom also lists a Massachusetts home improvement contractor registration for the company — that is BuildZoom's own record, not a state confirmation. No customers have written about them publicly, so there is nothing here about how the jobs went for the people who paid for them. If they are on your list, ask directly about the OSHA citations and what changed after 2019, ask for current certificates of insurance and workers' comp, and confirm the registration number with the state before you sign.
