LMCURBS

What LMCURBS does

LMCurbs is a privately held U.S. manufacturer and single-source supplier of metal building rooftop accessories, headquartered and operating from a single facility at 827 Fisher Rd., Longview, Texas. Founded circa 1964, the company has been in continuous operation for approximately 60 years, building a catalog organized around its core competency of custom-designed roof curbs, which serve as the foundational mounting platform for downstream rooftop equipment on standing-seam and trapezoidal metal roofs. Its product portfolio spans roof curbs, roof hatches, prismatic skylights (marketed under the Baylight sub-brand), automatic smoke vents, continuous ridge vents, louvers, exhaust fans, roof walks, access ladders, fall protection systems, repair caps, pipe flashings, specialty flashings, built-up roof accessories, and installation tools and hardware.

The company's technology base is mechanical rather than digital: products include fusible-link smoke vents that open at approximately 165°F, prismatic skylights claimed to reduce daytime electric lighting by up to 75%, and proprietary items such as the GripperFix attachment solution and CanDuit cable/conduit management system. A defining strategic relationship is the 25+ year authorized distributor partnership with S-5!, which gives LMCurbs privileged access to S-5! utility clamps (S-5-U, S-5-T), snow retention systems (ColorGard, X-Gard), and solar PV mounting solutions including the ProteaBracket.

LMCurbs operates a quote-based direct-sales model through an online quote system and serves commercial and industrial metal building end markets, including warehouses, manufacturing facilities, and agricultural buildings. Pricing is not publicly disclosed; transactions are project-driven. The company backs its roof curbs with a 20-year warranty. Operations are entirely domestic (United States) with no disclosed international footprint, no public ownership or institutional investors, no disclosed management team beyond President David Funderburk, no funding rounds, no M&A activity, and no AI or software product components.
