Cahill Roofing & Construction

Cahill Roofing & Construction covers the weather side of a Waltham house — roofs, siding, gutters, and snow off the roof in winter. The company says it has been family-operated in the area since 1994, with Joe Cahill running it. A homeowner who hired the crew in 2021 described a roof replacement and, later on, a gutter repair, and called the roofers reliable and thorough. Google shows a 5★ average from two ratings, and the company's BBB page carries an A+ grade. The website also calls the business an OSHA-certified construction company. One number to square up: BBB lists 23 years in business, while the company's own site dates itself to 1994 and says 32 years. For a Waltham-area roof, gutter run or siding job where the owner is the person you deal with, this is a straightforward call. Ask Joe to put the Massachusetts home improvement contractor registration and insurance in writing, and pin down what the roof warranty covers before the crew starts.
