We have had several roofers out to look at our attic space to increase ventilation: we had a pretty big problem with attic condesation. We have a hip roof on a 2200 sq foot ranch house- huge attic space! the house has soffits & a ridge vent currently. We have installed 3 turbines which greatly improved the ventilation, but we are still getting minor condesation on really cold days or days without wind.
We want to eliminate this problem completly to ensure we get a long life on our roof - it's only 3yrs old - put on by the previous owners which appears to have started the problem. We don't want to keep calling roofers in and throwing money at it when it doesn't completly eliminate the problem. I feel like the roofers are "guessing"
Who should I call to do a thorough assesment of the whole ventilation & insulation system together to fix the issue once & for all?
