We live in Arkansas where it is very hot and humid in the Summer. We have a vaulted ceiling. Our roof is 15 years old. The previous roof had powered turbine vents. Our current roof has non-powered vents. We have 3 of those and soffit vents EXCEPT for where our vaulted ceiling is. We have some mildew/mold on the Sheetrock on the half of our vault that does not have open attic below it and on our wood beam at the peak. We have had 2 contractors give us approaches on what is needed. The first contractor says we need to put in a ridge vent on the roof over the vault as well as add soffit vents. They want to cut out all Sheetrock and install baffles (although we can’t tell for sure, we don’t think there are baffles). Of course, this is very expensive. The second contractor wants to add a ridge vent, soffit vents, but says he doesn’t think we need baffles because of the age of the house (30+ years) and that the insulation would be compressed. He also wants to install turtle vents along that peak. I am concerned about this approach - everything I have read says not to install both of these as they will work against one another.
We currently have 3 non-powered turbine vents for the other parts of the roof.
We don’t know how to proceed at this point. We don’t mind spending the money to permanent fix the problem, I am just concerned that we will spend 7k+ to add vents, pull Sheetrock, repaint, etc only for the problem to recur. I don’t remember this being a problem before this roof - when we had powered turbine vents. That may solve the problem, may not, since we don’t have any soffit vents in that section. We are just wanting to make the best decision on how to proceed.
