Diamond Roofing will maintain its existing brand identity and leadership team, ensuring continuity for its current client base and workforce. By folding into the Greenwood platform, the company gains immediate access to expanded technical resources, including specialized waterproofing, masonry, and architectural metal fabrication capabilities. This transition aims to blend Diamond’s local reputation with the scale of a national top-10 commercial roofing contractor.

David Klein, CEO of Greenwood Industries, pointed to the move as an effort to capitalize on the established trust Diamond has cultivated since its 1947 founding. For Diamond owner Don DeStefano, the partnership serves as a growth catalyst, providing his team with enhanced operational support while preserving the business practices that have defined the firm for generations. Greenwood, which operates 15 locations across the Northeast, continues its aggressive strategy of acquiring specialty contractors to consolidate its influence in complex exterior building systems.
