Primeline Masonry and Roofing works out of Cambridge on roofing, masonry, chimney and waterproofing jobs across Massachusetts, and its Massachusetts home improvement contractor registration is active. The company says it's been doing this work since 2004, with 22 years of experience by its own account. Several reviews single out Terry by name for straightforward sales and pricing — reviewers describe him as transparent about costs, coming in on budget, and giving good advice when Primeline handled roof and masonry work over a weekend call. Other reviews describe specific finished jobs: a reroof covering both a house and a business, a flat roof and two chimneys done together, a kitchen balcony roof, a basement waterproofed after a leak, and a chimney "in poor condition" repointed back to fully functional. One reviewer notes the final cost matched the original quote exactly and that the crew kept work areas neat throughout. Something worth knowing before calling: every review on file — all 30, across Google and Angi — was posted between February and June of 2026, with none from the 22 years the company says it operated before that. About a dozen of them, dated within a few weeks of each other in February and March, use strikingly similar language across otherwise unrelated jobs (gutters, siding, a chimney, a basement) — phrases like "skilled manpower," "advanced tools," and "waterproofing compounds" recur nearly verbatim from one to the next. That doesn't mean the work described didn't happen, but it's a pattern worth being aware of alongside the more specific, individually distinct accounts naming Terry and describing particular jobs. If you're considering Primeline, the reviews naming Terry directly and describing a specific job — the reroof, the chimney repointing, the balcony roof — are the more grounded read on what to expect; it's reasonable to ask for references beyond the online review page.
The team came out and repaired my roof. I wasn’t home when they did it. However, by the team i get home everything was done and cleaned up. I would definitely choose them again.
I had these guys reroof my house and my business. Did a great job on both. They worked quickly and efficiently. I wouldn’t hesitate to recommend them. These guys are awesome. The communication, professionalism and workmanship are top notch.
Superb service, quick, good value and know what they are doing. Thanks very much for finding and sorting the issue.
