Lomanco has specialized exclusively in residential roof, attic, and crawlspace ventilation since 1946. Its lineup includes Whirlybird® turbines, Omni® Series ridge vents, and a full range of intake, gable, and foundation vents, all manufactured domestically. Proper ventilation extends roofing material life and reduces moisture and heat buildup — a detail worth getting right on every job Murphy's supplies.
Why Ventilation Is Part of Every Roofing Job
Lomanco has done one thing since 1946: attic and roof ventilation. That singular focus, starting with an adjustable louver invention, has grown into a full ventilation catalog manufactured out of Jacksonville, Arkansas and shipped nationwide.
Ventilation doesn't get the attention shingles or membranes do, but it directly affects how long a roofing system lasts. Poor airflow traps heat and moisture in the attic, which accelerates shingle aging from underneath and increases the risk of mold, rot, and ice dams in colder climates.
Balanced Airflow
Intake and exhaust products are engineered to work together, reducing attic temperatures and moisture buildup that shortens roofing material life.
Corrosion-Resistant Builds
Galvanized steel, aluminum, and durable plastics stand up to heavy rain and UV exposure across coastal and inland climates alike.
No-Maintenance Turbines
Whirlybird® turbines use upper and lower ball-bearing construction, turning in the slightest breeze without regular upkeep.
Product Lineup
- Whirlybird® turbines — 12" and 14" wind-powered turbine vents, internally or externally braced

- Solar & power vents — Omni Solar Vent and Omni Solar Gable Vent, no electrician required
Where It Fits on the Job
Lomanco products go on virtually every re-roof and new construction job, regardless of shingle brand — ventilation isn't brand-locked to the roofing material above it. Getting the intake-to-exhaust ratio right matters for warranty compliance on many shingle lines, and it's worth confirming Lomanco's balanced ventilation math on complex or multi-level roofs.

FAQ
What's the difference between a ridge vent and a turbine?
Ridge vents run continuously along the roof ridge for passive exhaust ventilation. Turbines are wind-powered spot vents that actively pull air out of the attic and turn in even a slight breeze.
Are Lomanco products made in the USA?
Yes. Lomanco manufactures its ventilation products domestically, operating primarily out of Jacksonville, Arkansas.
Is Lomanco available at Murphy's?
Yes. Lomanco is one of Murphy's stocked manufacturer lines. Ask our counter team which vent types are on hand at your branch.
