Homeowners often ask whether they need soffit vents or ridge vents. The real answer: you need both, balanced correctly. Here's how attic airflow actually works in Florida.

It's one of the most common questions we get: 'Should I add soffit vents or ridge vents?' The question itself reveals the misunderstanding — they're not competing options. They're two halves of one system, and in Florida's heat, getting that balance right protects your roof, your energy bill, and your attic.
Hot air rises. A properly vented attic uses that simple fact: cool air enters low through the soffit vents (intake) along the eaves, rises as it heats up, and exits high through the ridge vents (exhaust) at the peak. This continuous flow flushes heat and moisture out of the attic all day long, with no electricity required.
Soffit vents sit in the underside of your roof overhang. They pull in cooler, fresh air at the lowest point of the attic. Without adequate intake, even the best ridge vent can't move air — there's nothing to replace the air leaving the top.
A ridge vent runs along the peak of the roof, hidden under the cap shingles. It lets the hottest air escape at the highest point. Ridge vents are continuous and low-profile, which makes them more effective and better-looking than scattered box vents.
The #1 ventilation mistake in Tampa Bay homes: ridge vents installed with blocked or insufficient soffit intake. The result is a system that barely moves air — and sometimes pulls conditioned air from the house instead. Intake and exhaust must be balanced.
The general target is a balanced system — roughly equal intake (soffit) and exhaust (ridge) net free area, with at least 1 square foot of total ventilation per 150 square feet of attic floor (or 1:300 with a vapor barrier). If anything, slightly more intake than exhaust is ideal, so the system never starves for air.
When we replace a roof or soffit in Tampa Bay, we check the whole ventilation system — not just the part you called about. Adding a ridge vent without confirming clear soffit intake is a recipe for callbacks, so we make sure both ends actually work together.
It's never soffit vents versus ridge vents — it's both, balanced. Intake at the eaves, exhaust at the peak, sized to your attic. Get that right and you extend your roof's life, lower your cooling costs, and keep moisture and mold out of your attic, which matters enormously in Florida's climate.
