Ventilation is the part of the roof system that gets skipped, mixed, or guessed at - and it is the part that quietly decides how long the roof and the home hold up. That is the work we focus on.

Training and certification - Hands-on Lomanco training for crews and sales teams. Contractor training events. Lomanco Ventilation Certification. Hosted with local distributors. Job-site troubleshooting - On the roof, looking at the actual problem. Ventilation inspections. Intake problems and blocked soffits. Wrong or mixed exhaust vents.

Hot, wet attic air that cannot get out cooks shingles from below, drives moisture into the deck, and works against the home year-round. A balanced system pulls fresh air in low and lets hot air out high - continuously, without power. Intake low, exhaust high - Air enters at the soffit and exits at the ridge or high vents. Blocked or missing soffit intake starves the whole system. 50 / 50 balance - Half the required ventilation at intake, half at exhaust. More exhaust than intake pulls conditioned air - and weather - from the house. Do not mix exhaust types - Ridge vent, turbines, and box vents on the same roof can short-circuit each other, with the higher vent pulling air from the lower one instead of the soffit. Size it to the attic - The math starts with attic floor area and the 1:150 or 1:300 rule - then it gets checked against the vents actually being installed. Try it below.

This is Aron's take-off calculator, cleaned up for the web. Start with the roof size and pitch - it works out the attic area, the total ventilation required, and exactly how many Lomanco vents it takes, intake matched to exhaust.
Use the take-off calculator above: enter the roof square footage and predominant pitch and it estimates the attic area, then figures total net free area at the 1:300 rate - (attic sq ft / 300) x 144 - split evenly between intake and exhaust. From there it tells you how many of each Lomanco vent it takes and the intake to match. Confirm the published NFA of the vents you choose before installing.
Missing or blocked intake. Homes get exhaust vents added while the soffits are painted shut, covered by insulation, or were never vented at all - so the system can't breathe. Mixing different exhaust types on the same roof runs a close second.
