This one is a homeowner's question posted on a building forum, not a news story, so there is no finding to report yet. A homeowner with a ranch-style house asked whether installing an AirVent brand edge vent would still work if it gets buried in snow. Edge vents are a type of intake vent installed along the lower edge of the roof deck, used when a house lacks the usual soffit vents (the openings under the roof overhang that let outside air into the attic). Intake vents work with vents at the ridge or top of the roof to keep air moving through the attic, which helps control moisture and temperature.
The homeowner's house is in climate zone 6, a cold region, with a low-slope roof pitch of 3-in-12 (the roof rises 3 inches for every 12 inches it runs). In snowy climates, any intake vent near the roof edge can get covered by snow buildup, which raises the question of whether it can still draw in air when that happens.
No answers had been posted yet, so there is no verified guidance here about how edge vents perform under snow in this situation. If your own house lacks soffit vents and you are weighing an edge-vent product, it is worth keeping in mind that snow cover and roof pitch are both factors worth asking about directly with the manufacturer or someone familiar with your specific roof and climate.
