Typical Greater Boston range for this kind of work, from regional averages — not a quote from J4 Roofing Contractor of Bridgewater. 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.

A high wind storm knocked shingles into someone's yard in December 2021, and J4 had inspected the attic and replaced them again that same afternoon — the kind of turnaround people keep describing about this East Bridgewater roofer. J4 LLC has worked from 650 Plymouth St. since at least 2016, when its written reviews begin, and a 2020 local business profile said the company had been roofing in Massachusetts since 2000, with Joel Baggia running it from the start. The story across nine years of reviews on Google, Angi and BuildZoom stays consistent: crews strip and reroof a house in a single day, several homeowners hired them more than once, and the name attached to most of the praise — Joel — shows up whether the job was a full tear-off on an old farmhouse or an afternoon shingle repair. Angi's 14 reviews run 93% five-star, and a 2017 customer who said he compared several roofing companies before choosing J4 wrote that the crew clearly wanted the business and finished a full reroof in a day at a competitive price. Its Massachusetts home improvement contractor registration (#185349) is active on the state licensing board, and the company is GAF Certified with a Systems Plus Warranty, a manufacturer credential tied to the shingle systems it installs. One thing worth clearing up before booking: the company's own site advertises 24/7 emergency roofing, but Angi's listing for J4 states the opposite — that it doesn't offer emergency service — so a direct call is worth it if a storm just hit. A 2016 reviewer who was otherwise satisfied rated the company's customer service a 7 out of 10, the one mildly mixed note in an otherwise strongly positive record. For a straightforward roof replacement or repair in East Bridgewater and the surrounding South Shore, J4 has the track record for it — just confirm same-day emergency availability by phone rather than assuming it from the website.

Joel was wonderful. Explained everything to me clearly. The crew were great. They cleaned everything up wonderfully and the whole job was done in a day. It's so nice to work with such good people. I love looking at my new, moss free roof.
