Diligent Builders, Inc.

Diligent Builders, Inc. is a roofing, siding, and gutter contractor based in Westborough, Massachusetts, run by an owner customers refer to as Al or Adolfo. The company's own website says it has been doing this work since 1999, with a focus on asphalt shingle roof replacement and repair, manufacturer-certified installation, and keeping job sites clean. The written reviews on file, all from 2018 and 2019, are uniformly positive. Customers describe Al and Adolfo as professional, punctual, and thorough, going beyond a basic roof job to point out and fix underlying issues like weak decking or chimney flashing. One reviewer, who had used the company for multiple projects, called the cleanup and overall quality outstanding. Diligent Builders holds a 5.0 out of 5 rating from all 4 reviews on Angi and HomeAdvisor. How long the business has actually been operating is unclear: its own site says 1999, BBB's file lists 2006 as the start date with 20 years in business, and Angi and HomeAdvisor list 36 years of experience -- worth asking about directly. BBB also lists two Massachusetts license numbers on file, though the business is not a BBB accredited business and carries no BBB rating. For a Westborough-area homeowner who wants a roof replaced or repaired, or new siding and gutters installed, Diligent Builders has a small but strongly positive review history and self-reported manufacturer certification. It's worth confirming current licensing directly and getting a written, itemized estimate before work begins.
