I live in coastal Delaware and it is time to get a new roof. We have two turbines installed within a foot of the ridge that even on a still day are in motion. I have two questions:

1. One roofer quoted a ridge vent installation with removal of the turbines, saying to have both is counterproductive. Another roofer quoted a ridge vent without removing the turbines. When I asked him, he said, "The roof turbines can draw air out of the ridge vent but they help on the overall air flow of your attic" and whether I keep them or remove them is my preference. Should I remove them or keep them?

2. I was trying to find an answer to the above on the internet, and the information seemed to indicate I need intake area equal to the venting area. I have only one small louvered eave vent, about 7"x7" or less. This does not seem sufficient. Can I be missing something?

FYI, the house was built in 1984, and I'm told this area did not have building codes at that time.

Thank you.

Added information to above. I now see I also have triangle louvered vents at the ends of the house just below the peak of the roof, about 12" high and 18" wide.
