O'Hagin Fire & Ice
Rohnert Park, CALow-profile attic vents for tile, comp shingle, shake, slate and metal roofs.
They say: Designed for superior airflow with ember protection, per O'Hagin.
Roofs catch embers first. Low-profile roof vents keep attic air moving through a small, shielded opening instead of a tall vent cap.
Protection is RF1's read of published tests, not a lab rating. Prices are rough ranges based on a 2024 California study, not RF1 quotes.
How it works
The vent sits low on the roof, so wind-blown embers have less to hit.
Inside, 1/8-inch metal mesh and a stainless steel filament catch embers before they reach the attic.
O'Hagin says its ridge and off-ridge vents can't be tested under the standard vent test, so they comply through the roof-vent mesh path in California's 2026 code.

What it costs
Rough installed costs, based on the 2024 Headwaters Economics study. Retail prices for O'Hagin vents run roughly $45 to $52 at one retailer we checked.
