Roofing and siding are what people call Loja General Construction Inc for. Based at 60 Louis St in Brockton, the crew's forty-two Google and Thumbtack reviews going back to 2022 circle around the same jobs again and again: a leaking roof found and fixed, old vinyl or wood siding replaced, a chimney's fascia and flashing patched before winter. Reviewers keep naming the same few people running the work — Dave (also written David), Jose, and Ruben come up repeatedly as the ones who showed up and did the job. The track record is deep and almost entirely clean. Several reviewers describe getting an estimate in the afternoon and the crew finishing the next morning; one homeowner got quotes from five contractors and said Loja's was the fairest of the bunch, while others simply never showed up. A general contractor of forty years wrote in 2025 that after his two longest-tenured employees retired, he hadn't seen a crew as good as this one. Another customer had them reside a large multifamily building and called the finished work better than expected. Twelve reviews landed in just the past six months, all of them positive, on top of jobs going back to storm-damage repairs, roof and skylight replacements, and routine gutter cleanings in prior years. Its Massachusetts home improvement contractor registration is active, confirmed directly with the state. BuildZoom's own directory also turns up two older, now-inactive registrations tied to the same address — one Massachusetts, one Rhode Island — which is worth a quick question but isn't unusual for a business that has changed hands or re-registered over time. The one blemish on the review record is a single one-star Google rating from 2022 that offers no explanation of what went wrong, so there's nothing specific to weigh against everything else. For a roof repair, a full re-roof, or a siding job — especially the kind that follows storm damage — this is a crew with a long, recent, and consistently strong record behind it. Worth confirming directly: the exact towns covered within the five counties the company lists on its site, since that's stated only at the county level.
I appreciated the honest assessment. Most contractors would take advantage of customers and give inaccurate evaluation just to make money, not David. He was on time, courteous and professional.
I needed a contractor last minute to cut hole for a roof vent . They were professional, and worked with our tight timeline. They also found some other issues and fixed everything and provided pictures of all work. Will definitely use again !
The workmanship of the crew on the roof repair was absolutely first-rate. They took the time to do a thorough, careful, professional job and left the house and yard spotless afterward. As roof repairs go, I couldn't have expected a better experience.
From start to finish great job. Very professional, on time, great work, answered all questions and clean up the the deck and yard when done. Would absolutely recommend.
David and his crew did a great job removing the moss from our roof, as well as many sticks and small branches that had fallen from the large oak trees. He was very responsive from his first visit to estimate the work to its completion.
