About Us


Diamond Roofing started in business as a general contractor in 1986 before focusing solely on roofing in 1993 to become South Jersey's premier roofing specialist. We are fully licensed and insured in New Jersey. Our work is owner supervised by Dave Mikulski, and includes a 10-year workmanship warranty.  Our associates are dedicated to Diamond Roofing and strive to provide customer satisfaction.

We accept cash, personal checks, all major credit cards, and offer limited financing.
