For seven decades, Diamond Roofing has lived by the philosophy of serving the customer above all else. When Louis DeStefano founded the company in 1947, he set the bar high for generations to come. Right from the start, we’ve worked tirelessly to bring new services and capabilities to our ever-expanding list of customers, and today we proudly point to our work – prominently visible on much of New York State’s finest architecture.

In the 1980s, Diamond added sheet metal fabrication and environmental asbestos abatement to our roster of services, and we soon became known across the region as experts in these and other fields complementary to roofing.

Of course we’ll always be a roofer at the core, and that’s where our craftsmen shine most brightly. From small re-roofing projects to historic multi-million-dollar restorations, we still provide a level of quality that would make our founder proud.

And while some other firms’ employees may come and go frequently, Diamond boasts a remarkable retention rate. Our people are fully committed, highly trained and have made your satisfaction, their life’s work.
