Diamond Roofing

What Diamond Roofing does

Diamond Roofing is a privately held commercial roofing contractor founded in 1947 and headquartered at 411 Cambridge Avenue in Syracuse, New York, with a workforce in the 11-50 employee band serving the Central New York region. The company installs and maintains a full portfolio of commercial roofing systems — EPDM, TPO, PVC, modified bitumen, slate and tile, metal, and green/vegetative roofing — and operates an in-house sheet metal fabrication capability for architectural elements (gutters, window hoods, chimney caps, wall cladding, mansards, fascia) in copper, stainless steel, galvanized steel, aluminum, and brass. It also holds a New York State license for asbestos abatement and runs a 24/7 emergency maintenance and repair service. Diamond's customer base skews heavily to institutional and public-sector accounts, with documented projects at Syracuse University (Hall of Languages, Bowne Hall, Ernie Davis Hall), multiple K-12 schools, Upstate University Hospital Cancer Center, the Jamesville and Lansing correctional facilities, the Onondaga County War Memorial, the Cathedral of the Immaculate Conception, and NYS Fairgrounds.

The business model is project-based and quote-driven: revenue is generated per-project from one-time roofing installations and restorations (referenced up to multi-million-dollar scope) supplemented by ongoing maintenance contracts and emergency repair revenue. Pricing is custom per project based on roofing system, square footage, and complexity; no standardized rates are publicly disclosed. Go-to-market is direct-to-customer field sales supported by a website with a 'Request a Free Online Quote' funnel, project portfolio content marketing, organic SEO across individual roofing-system pages, and referrals from architects and administrators. Distribution is regional (Central New York) without geographic intermediaries. Factory certifications from Carlisle, Sika Sarnafil, Johns Manville, Firestone, and Siplast underpin warranty-eligible installations and the company's 4.9 million sq ft of documented single-ply volume.

Ownership transitioned on June 30, 2026, when Diamond was acquired by Greenwood Industries of Worcester, Massachusetts. Diamond continues operating under its existing name and leadership while being gradually integrated into Greenwood's broader operating platform for safety programs, technical expertise, and operational resources. The company is no longer an independent family-owned business and is now a regional subsidiary within a larger commercial roofing platform.
