Sometimes it’s not an either/or thing—it’s more like a balancing act.
You nailed it. I’ve seen folks obsess over sealing every crack, then wonder why their attic’s still a swamp. Especially with older houses, original ventilation is almost always lacking. I’m with you—if you don’t get enough airflow, you’re just locking in problems. It’s not just your luck; these old builds rarely play by the book.
That’s a good point about airflow. I’m still trying to wrap my head around how much venting is actually enough, though. Like, is there ever a risk of adding too many vents and messing up the balance? My uncle’s old place had a bunch of random roof vents added over the years, but it just seemed to make drafts worse in winter. Anyone else see that, or did they just do it wrong?
I’ve actually seen that happen—too many vents can mess things up, especially if they’re not balanced between intake and exhaust. My dad’s house had a bunch of extra roof vents added over the years, and in winter you could feel cold air moving through the attic way more than before. I think it’s less about the number and more about where they’re placed and making sure you’ve got enough soffit vents to match. Just slapping on more roof vents doesn’t always help, sometimes it just pulls in more cold air.
Had to laugh reading this—reminds me of my old place before we moved. The previous owner must’ve been a vent fanatic because there were more roof vents up there than I could count. Thought it’d help with heat in the summer, but all winter long you could practically feel a draft if you stood under the attic hatch. My wife used to joke we should just store ice cream up there.
Turns out, like you said, it’s not about cramming as many holes in the roof as possible. We had barely any soffit vents, so all those roof vents just sucked in cold air and made things worse. Ended up paying someone to block a couple off and add proper intake down low—problem solved. Funny how sometimes “more” just means “colder” when it comes to roofs... Live and learn, I guess.
- Had the same issue in my last house—thought adding a bunch of roof vents would help, but it just made the upstairs freezing in winter.
- Figured out later it’s all about balance. More exhaust doesn’t work if there’s no intake down at the soffits.
- Ended up sealing a few vents and installing more soffit vents. Made a noticeable difference, especially with ice damming.
- It’s weird how easy it is to overdo it... Sometimes less really is more when it comes to ventilation.
