Rainscreen venting connected to cold roof/back vented channel
Thoughts on connecting the vertical rainscreen vent channel to the cold roof/back venting channel on the roof or separating them.
I saw this last winter where the two channels are connected:
The solar washing of the siding caused subsequent ice damming even on a cold roof, due to the warmer air that comes from behind the siding was escaping up, under and out the roof peak. Anyone else encounter this?
Have you seen details that could eliminate this, but still provide an easy pathway for the vented air to escape?
