Lomanco

What Lomanco does

Lomanco is a family-owned US manufacturer of residential and light commercial ventilation products, founded in 1946 as Dan-Dee Manufacturing Company in Minneapolis and headquartered since the mid-1960s in Jacksonville, Arkansas. The company operates exclusively in the building products segment, producing roof and foundation ventilation systems for homeowners, homebuilders, roofing contractors, and building products distributors across the United States; international markets are not served. The company remains under family ownership, with Dennis and Ted Belden (grandsons of founder Clark David Belden) listed as sole owners since 1994, and there are no external institutional investors or public filings.

Lomanco's product portfolio is organized across exhaust vents — Whirlybird turbines (dual ball bearing, lifetime/forever guarantee, since 1978), OmniRidge and OmniRoll ridge vents, multiple static roof-vent series, LomanCool power vents, and Omni Solar attic and gable vents — intake vents such as Deck-Air and Cirk L, and specialty products including foundation/crawlspace vents, Bath PRO and Kitchen PRO roof jacks, cupolas, weather vanes, and (from 2025) Universal Flat Tile Roof Vents. Manufacturing is conducted at a 10+ acre Jacksonville, AR complex and at Lomanco West, a wholly-owned subsidiary in Kingman, Arizona established in 1980, with a 65,000 sq ft warehouse expansion completed in 2023 and a further 68,000 sq ft expansion under construction in 2026. The company complements its hardware line with a Vent Selector mobile app for iOS and Android, a web-based ventilation calculator, and PRO Vent Tools for dealers.

Lomanco generates revenue through one-time hardware sales and replacement parts distributed via a direct e-commerce store (Lightspeed backend), toll-free phone sales, and a two-tier wholesale network supplying building products distributors and lumber yards nationwide, supplemented by an Area Market Manager (AMM) program that manages dealer relationships. Pricing is unit-based and ranges from approximately $23 for turbine accessories to roughly $870 for premium solar-powered attic vents. No subscription, software, or recurring revenue model exists. Revenue figures are not disclosed, and there is no API, SDK, or AI/ML product layer.
