I had my roof replaced 2003. I was told ridge cap venting is really good and will help keep the house cooler during summer. Paid extra for it. The ridge cap had to be replaced within a couple years. Then in 2008 we noticed moisture. Contractor came out and attic was full of moisture and plywood destroyed. We were told that adequate venting along the eves was the problem. Previous owner must of had insulation blown into the attic and covered some of the vents. My wife and I unplugged all the vents. I was also asked to put humidity thermostats on the attic fans on both ends of the roof. I did that and the problems were determined resolved. A new roof was installed on warranty replacing all the plywood and ridge cap venting was installed again.
Within a few weeks of install we got warm weather at about 70 degrees and the attic fans ran. This happened several times so I called the contractor back. I told him that was really unusual and never had the fans come on till it got hot 80 to 90 degrees. I was told everything is to code and should be good. I still asked why is it doing this?? That was 2008.
I haven't looked in the attic for some time figuring it is all working fine. Well recently one attic fan comes on and stays on for 24 hours. After a couple hours of it running I got a ladder and removed the attic access panel. Got a light and was very displeased with the attic. It is all wet with moisture and mold.
I had a roofer working on a local house come look at it. He told me they don't recommend ridge cap venting and have seen a lot of houses with the same problem. Also with attic fans they should of never installed the ridge cap venting. The roofer told me this roof is in really bad shape and needs to be replaced real soon. He said it is a real health risk. He advised me to get the person who installed it out and fix it right or get an attorney to go after them.
The original roof did not have moisture issues of any kind. The original roof had the conventional metal mushroom shaped vents. The roofer told me the Ridge Cap venting is not working and he could feel warm heat in the attic which tells him it is not ventilating properly. Also ridge cap venting gets build up on it that eventually blocks air flow. He agreed if I already had an issue with the attic fans coming on with mildly warm weather then it must of not been properly ventilating since installed.
Now I have to try to get the company that replaced the roof a second time in 2008 to replace it again due to improper install of ridge cap venting. I can't see anything else causing this problem. All the eve vents are open as requested prior to replacing the roof in 2008. The only other possible reason is the ridge cap venting not letting the roof breath properly.
