I’ve seen the same thing—perfect insulation, but vents totally useless from being packed with debris. Ever run into situations where adding more ventilation actually made things worse, like too much cold air causing pipes to freeze? Just curious how you balance that.
I’ve actually seen that happen—too much airflow and suddenly the bathroom pipes are freezing up in January. It’s like, you want to keep the attic cool, but not turn it into a walk-in freezer. I think it’s all about finding that sweet spot... not just cramming in more vents because “more is better.” Sometimes less is more, especially in older houses where the insulation isn’t perfect.
That’s spot on—too much ventilation can backfire, especially in these drafty old houses. I had a place last winter where we added a couple extra roof vents thinking it’d help with ice dams, but then the upstairs bathroom pipes froze solid. Turns out, the insulation around those pipes was never great to begin with, and the extra airflow just made it worse. I’ve found it’s usually better to focus on sealing up gaps and making sure the insulation is actually doing its job before messing with venting. Sometimes less tinkering is the way to go.
I get where you’re coming from, but I’ve actually had the opposite experience in my place. When we moved in, there was barely any ventilation and the attic would get crazy warm even in winter, which led to some nasty ice dams. After adding a ridge vent and making sure the soffits were clear, things improved a ton—no more leaks or icicles hanging off the gutters. I do agree insulation’s key, but for me, getting the airflow right made a bigger difference than just sealing gaps. Maybe it depends on the house layout or climate?

That’s what I keep wondering too. I’m in upstate NY, and our winters are brutal—lots of snow, big temp swings. My attic was always freezing cold, but I never had much trouble with ice dams until we beefed up the insulation a couple years ago. After that, weirdly enough, we started seeing more icicles and even a small leak near the chimney. I thought better insulation would help, but maybe we messed up the airflow somehow?
Curious if anyone else has run into that—like, can you actually over-insulate and make things worse if you don’t have enough venting? Or is it just a sign we missed some air leaks somewhere? Our roof’s got a pretty low pitch too, which probably doesn’t help. Just feels like there’s no one-size-fits-all answer with this stuff...
