I read the good article on building a vaulted ceiling — too late
I read the good article on building a vaulted ceiling. However, that is too late for me since I already have vaulted ceilings throughout my house.
In the areas where there is unobstructed venting from the soffit to the ridge vents all is well. But in three places I also have large dormers framed into the vaulted ceiling. Where the rafters intersect the valley rafters it creates a dead space where there cannot be any air circulation although in each case there is a ridge vent. The rafters are TGI 14" with R30 insulation batts sealed with visqueen. However, the finished ceiling is tongue and groove spruce.
After researching on your website I now know the mistakes made in construction. But, what can I do now to alleviate the condensation problem? I am in zone 5B at 8,000 feet altitude and even though there is much snow in winter it is still very dry. And I keep the humidity low in the house 10-20% but still get condensation and then thawing in spring and dripping down the walls. I am attaching pictures.
Any help will be appreciated.
