Verified record
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. Separately, BuildZoom lists a Rhode Island residential contractor license for the company that it shows inactive, with a November 2013 expiration, though the same listing elsewhere marks it active — worth confirming current standing directly if the job is on the Rhode Island side. 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.

A square is 100 sq ft of roof surface — bigger than the floor plan because of pitch and overhangs.

“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.”
Did an A+ job on my new roof, super nice, friendly team. Great communication throughout, and incredibly helpful. Wouldn't hesitate to recommend these guys.
