M.J. Ambrose Enterprises, Inc.

M.J. Ambrose Enterprises is a Dedham commercial roofing contractor that says it has served Greater Boston since 1989. The company describes itself as independent and owner-operated, with principals involved in significant projects, and focuses on roof inspections, maintenance, repairs, and low-slope, slate, and copper systems. Its public customer trail is thin: one Google review, dated October 2024, carries a one-star complaint about being yelled at over a parking spot rather than describing roofing work. That comment explains the low published Google rating but does not provide a useful account of installation or repair quality. The company says it is an approved applicator for Carlisle SynTec, Sika Sarnafil, Elevate, GAF, and Johns Manville systems. Its Massachusetts home improvement contractor license 219998 is registry-verified active, while its website claims 37 years in business and says the business is licensed and insured. M.J. Ambrose is best suited to commercial and institutional owners seeking inspections, planned maintenance, leak response, or low-slope roofing work. Before booking, ask for recent project references and clarify the scope, warranty, response terms, and who will oversee the work.
