Gaco Western

What Gaco Western does

Gaco Western is a US-based specialty chemicals manufacturer founded in 1955 and headquartered in Nashville, Tennessee, producing liquid-applied coating systems for the building envelope. Its product portfolio centers on 100% silicone roof coatings (GacoFlex S42, S20, S2100, GacoRoof), acrylic elastomeric roof coatings (GacoFlex A48, A47, 127 and 129 Series), urethane coatings (U91/U92, PU 300), and spray polyurethane foam roofing systems (GacoRoofFoam F2733RHFO with HFO blowing agent), supported by accessory lines for flashing, seams, primers, walkways, and construction adhesives/sealants (GacoBond, GacoSeal). The underlying technology is proprietary in-house chemistry, with up to 90% of products manufactured internally and a stack of third-party certifications including NSF P151, FM Approvals, UL Class A fire rating, ASTM D6083, California Title 24, and Energy Star.

The company operates as a business unit under Amrize, which became an independent publicly traded company following its 2025 spin-off from Holcim; Gaco sits alongside the Enverge brand within Amrize. Gaco's go-to-market is enterprise field sales delivered through a nationwide network of local area managers and an authorized dealer/contractor locator channel, with pricing conducted on a quote basis. It serves four primary customer segments — roofing contractors and applicators (the primary commercial channel), architects and design professionals, commercial building owners and property managers, and residential homeowners — through segment-specific content, AIA-approved training programs, GacoUniversity contractor certification, and a Contractor Recognition Program. Revenue is generated through one-time product sales across roof coatings and restoration, deck and waterproofing, adhesives and sealants, and spray foam insulation, with the company reporting that its products cover millions of square feet of buildings across every US climate.
