I’ve run into the same thing after switching to peel-and-stick on my place a few years back. Didn’t get full-on condensation, but I did notice a bit more dampness in the attic during the first winter. For me, it turned out to be a mix of the new underlayment and some old soffit vents that weren’t pulling their weight. Once I beefed up the ventilation, things balanced out. It’s easy to blame the underlayment, but airflow really is a huge factor—especially if your climate swings between humid and cold.
Yeah, that’s pretty much spot on. I see folks get all worked up about the underlayment, but honestly, if your attic’s breathing like a heavy smoker, you’re gonna have issues no matter what you slap down. Had a buddy who swore his new synthetic stuff was “sweating”—turns out he had a family of squirrels blocking half his vents. Sometimes it’s the simple stuff, right? Glad you got it sorted.
Yeah, ventilation gets overlooked way too often. Folks blame the underlayment when really, if the attic’s not moving air, you’re just asking for trouble—doesn’t matter if you’ve got the fanciest synthetic or old-school felt. Seen a lot of “sweating” complaints that turned out to be blocked soffits or critters nesting up there. Glad you figured it out before it got worse. Sometimes it’s not about what you put down, but what’s going on above and below it.

Couldn’t agree more. I’ve swapped underlayments a few times thinking it’d solve moisture issues, but turns out, a family of squirrels had set up shop and blocked half the vents. Lesson learned: always check for furry freeloaders before blaming the materials.
