Diversified Roofing Systems is a New Bedford flat-roof specialist — the site says the family has been in roofing since 1959, and the company itself was incorporated in Massachusetts in February 2000, now running a second office in Cranston, RI. The work described is mostly commercial and industrial: single-ply and rubber membrane systems, tar-and-gravel, slate, metal and sheet-metal roofing, cool roofing and infrared moisture scanning, plus roof inspections. The written record on file is thin and dated: two 5-star Google reviews, from 2016 and 2018, both describing a friendly, communicative crew on a new-roof job. Its Better Business Bureau profile has carried an A+ rating since the company was accredited there in 2016, with no complaints shown. Two things worth asking about directly before hiring. A 2019 local news report tied the company to a worker's fatal 40-foot fall and noted OSHA had penalized it for safety violations the prior October — ask how the company addressed that. An August 2023 local news report says Richard Miranda Jr and the company were indicted by the Bristol County Grand Jury on 104 counts of violating the Massachusetts Clean Air Act. Separately, BuildZoom lists a Rhode Island residential contractor license for the company, with a November 2013 expiration. For a flat or specialty roof job — commercial, industrial, or a single-ply/rubber residential re-roof — the reviews on file describe a crew that communicates well; just raise the safety and licensing questions before signing anything.

“Richard Miranda, Jr., age 47, of Acushnet, and his company, Diversified Roofing Systems, Inc., were indicted last week by the Bristol County Grand Jury on 104 counts of violating the Massachusetts Clean Air Act.”
“While the events leading up to Simons’ 40-foot fall are unclear, Eyewitness News has learned this isn’t the first time Diversified Roofing has been investigated. Records show that last October, the company faced penalties from OSHA for safety violations. Eyewitness News reached out to Diversified Roofing for comment but our calls have not yet been returned.”
