Now that`s different. Excessive noise that you hear inside or outside your home is not normal. When the wind blows hard, it lifts the air in your attic out of the ridge vent faster than radiant lifting when there is no wind. Draws it in throuigh the soffit vents. ( prop vent should be installed at least the first three feet) In the attic you can hear the air flowing durring strong winds.

If the noise you described did not exist prior to the ridgevent installation, the faster flow durring wind is probably vibrating loose debris or vent joints, I`ve also encountered shingle tape not cut off at the top and vibrating in the wind.

Louder noise shouldn`t be the vent itself, unless it is one of the metal kind that don`t need cap shingles over it. Not installed correctly can rattle them around and it`s noticeable throughout the house or yard.

Ideally you should close off the gable end vents, (recommended) from the inside, they counter the flow from bottom to top.

Again, check for debris or loose material vibrating, have a pro go on the roof to check if you find nothing inside.

You should see daylight at the tip top cutout, and the bottom where the floor meets the roof. (soffit vents) Turn off the light to check.

Otherwise,...I`d have to be there, and I`d go up on the roof too.

Let us know after.

CoreVent has baffles in their vent products that might reduce this problem for you

Just encountered something very similar last night after having new roof with ridge vents installed earlier this year. In my case, listening from inside the attic, I was able to isolate the source to a short section of vent between a couple of trusses. Feeling about I found that the top course of shingles terminated something like 3/4" below the open plywood edge and the GAF DeckArmor I'd specified instead of felt was protruding unattached about that distance. I cut some short sections of aluminum seam tape I happened to have, folded them lengthwise so that I was able to tuck the tape up in there and secure it to hold the DeckArmor down. My confidence in this solution isn't yet 100%, but so far so good. I believe that flap was vibrating in the wind producing an intermittent groaning noise; it seems not unlikely that wind could have a similar effect on ordinary roofing felt.

Yeah I need a new roof as well, it's never good when you got leaks coming in. My cousin just got his roof done last fall and he loves it. I think he found some San Jose roofing contractors to install it.

You have to be sure when talking to contractors. There are a lot of scam artists out there. Make sure you get referrals and do research on different companies before hiring. My cousin recently got a new roof and did a ton of research on different Indianapolis Roofing Contractors before choosing their new roof and found the right one for him. You just have to put the time and effort into it.
