- Noticed the same thing with metal roofs—condensation’s a real issue, especially in colder climates.
-
“I had to add a vapor barrier and extra insulation in the attic after my first winter with metal.”
That’s pretty much what I’ve had to do on a few properties. Vapor barrier plus R-38 insulation seems to keep things under control, but I still get nervous during freeze/thaw cycles.
- One thing I’ve seen: even with good insulation, if the attic isn’t ventilated right, moisture finds a way in. Had a place last year where the ridge vent was blocked by snow for weeks—ended up with minor mold on the rafters. Not fun.
- Curious if anyone’s tried those powered attic fans with metal roofs? I’ve heard mixed things—some say they help, others say they just pull warm air out and make the condensation worse.
- Also, anyone dealing with ice damming under metal? I thought metal would solve that, but apparently not if the insulation/ventilation isn’t dialed in.
