Help! Range hood roof cap?

Posted by frank04090 (My Page) on

We have a 600 cam range hood that is starting to be installed. The contractor picked up a roof cap, but it's one of those nutone low profile ones. (My contractor sucks, long story but I question everything he touches) I don't think it's good for this application. A small amount of grease will escape out through the vent and this would blow toward the shingles I would think, and could easily be blocked by snow in the winter.

Or is this the correct style?

It's a 5/12 pitch roof. 600cfm peninsula, 8" pipe mostly straight up.

Thank you for your time.

I'm using one of these for our 1266 cfm blower.

My parents have had one for decades, but not in a snowy environment. Grease is not a problem. With snow it would depend on how often you ran it since the warm air would melt the snow around it.

Many like the low profile style because it is low profile. If snow or grease are issues, then an upblast style housing (without the fan and motor) can be used, although available sizes might need to be adapted to a mere 8-inch duct. The flange extension it sits on can be fabricated to meet various roof pitches and anticipated snow depths.

The cover of the linked document illustrates what an upblast housing looks like.
