Had used ridge vent on this home as it was recommended by three people I trust. Happy I used it but have thoughts on it.
Call Airvent up to ask about snow as had seen your posts here the odd time how does it work in the snow. Was told in Colorado it does not work now but it will work up to about 22" of snow.
The theory is it has turbulance and pushes the snow away. From the ground I cant see and since I don’t trust anyone I went up yesterday.Not the best to be on a roof with 3" of snow at this time of the year.
Probably 80 percent of the vent was plugged or covered over completely. One area where it is warmer down near the chimney was all clear. The rest was mostly covered with a few little holes poking through.
So I called up again and said it was supposed to clear itself, I have enough soffit cutouts as it is cut continous all the way around the home at the bottom back edge of the facia board.
This last person said it will get covered but it will still breath through the snow. I said how much? She said don’t know but you won’t get your 18" of air.
I don’t think anything was done wrong and guess I will have to go into the attic to look around a bit but at this point it seems to me that the stuff does get covered with a minimal amount of snow.
If someone understands it inside and out would you explain it to me or if I am missing something.
People scoffed at whilrly birds and there was one other style like a whirly bird with no moving parts that I bought to consider to put three before the ridge vent entered the picture.
Without looking it up think it is Shingle Vent II. It is hard plastic, four foot sections, covered in shingles, has tons of little slots in it and a fine mesh I guess to stop the snow from getting in.
