What Custom Curb Inc. does
Custom Curb Inc. is a veteran-owned, family-operated custom metal fabrication company that has been in continuous operation since 1989. The company was founded by Jack Haas, a U.S. Navy veteran who remains CEO, and relocated from Chattanooga, Tennessee to Ventura County, Southern California in 2010. It specializes in fabricating aluminum and galvanized steel components for sloped and flat metal building roofs.
Its core product lines are roof curbs, skylights, roof walks, smoke vents, wall louvers, equipment hatches, access ladders, industrial fans, and gravity vents, sold as engineered-to-spec material items (not subcontracted labor). Specialized offerings include spring isolation curbs and equipment covers/curb caps purpose-built for data center facilities, representing a higher-margin product extension. Customization includes pitch-correction for non-standard roof slopes, with an in-house engineering capability supporting custom drawings per project.
The business model is project-based direct-to-contractor and OEM sales, with Custom Curb positioned as a material supplier shipping nationwide from its single Ventura facility. Customers include commercial contractors (Colton Constructors, Mechanical Services, NME Builders, Span Construction), solar integrators (Solar Industries), and government buyers (the United States Navy). Pricing is custom per specification; the firm backs its work with a 10-year warranty and reports a 5.0-star average review profile. There are no disclosed funding events; the company is privately held and bootstrapped.
