Honest inspections come up again and again in Glas J Roofing's Google reviews — the kind where the inspector tells you the roof doesn't need replacing. In a January 2026 review, a homeowner said salesman Isaiah Colon inspected the roof and was transparent that there wasn't enough damage to replace it. An October 2025 reviewer said Braden gave an accurate, straightforward assessment and didn't try to sell anything, and another from that month said the crew weren't trying hard to upsell. The company is based in Walpole and describes itself as a roofing contractor offering 24/7 emergency leak repair, full roof replacement, gutter service and preventative maintenance. Its Google listing shows 5 stars from 27 ratings, and the written reviews run from September 2025 to March 2026. Leaks are a regular reason people call. In a March 2026 review, a homeowner whose roof leaked after heavy rain said the crew came out within an hour, found the problem and fixed it, saving the ceilings and insulation. A December 2025 reviewer said they were quick to fix a roof leak and that CJ Munro answered all their questions. Full replacements show up too. A November 2025 review described Kyle, Patrick and the roofing crew replacing a roof damaged by a late June storm. An October 2025 reviewer said Julio kept them informed, helped them choose the material and finished all the work in one day, as he said he would. In December 2025, another customer was scheduled within a week of accepting the quote and saw the job completed in a single day. Gutters and trim round it out. A March 2026 review described a gutter replacement and trim job where the team matched the new color to the siding, at a price the customer called reasonable. In October 2025, a homeowner with an overflowing gutter said two workers came quickly, took photos and checked the other gutters and downspouts as well.
Extremely pleased with the gutter replacement and trim work. The team took care to match the new color with our siding. Pricing was reasonable, and the crew was courteous and tidy. Would definitely recommend to neighbors looking for solid exterior updates.
Our roof leaks since the recent rainfall. They came out within an hour. They quickly identified the problem and fixed it. Due to the quickness with which they resolved the problem, we were able save our ceilings as well as our insulation.
Exceptional service. The roof installation went well. The crew did a fantastic job in cleaning up everything after the project was completed. The project manager and administrative staff were excellent, from the initial contact until the end of the project.
Jacob was a pleasure to work with and I am very impressed with the service he provided. From the start, he showed a high level of professionalism and responsiveness. He was very knowledgeable and experienced. Jacob is highly recommended to anyone who needs roofing services. His dedication to customer service is truly top-notch.
I was extremely pleased with the knowledge and honesty of the salesman Isaiah Colon. He came and inspected my roof. He was very transparent in telling me that there wasn't enough damage to replace my roof. I appreciated that he took the time and didn't try to trick me. I feel like Isaiah Colon has given me some great insight about my roof.

Typical Greater Boston range for this kind of work, from regional averages — not a quote from Glas J Roofing. Use it to sanity-check bids, then get the real number in writing.
