just read about roof issues popping up after winter - are you checking yours?

I’m right there with you on the “it’s not always as simple as just adding more vents” point. We’ve got a 1960s ranch with a low-pitch roof, and when I first moved in, I figured more ventilation would be a quick fix for the attic getting stuffy in summer. But after poking around up there, it turned out the soffit vents were almost completely blocked by old insulation. No amount of new roof vents would’ve helped until I cleared that up.

I did end up tracking attic temps and humidity for a while - just cheap sensors from the hardware store. Before I fixed the airflow, the attic would hit 120°F on sunny days, and humidity stayed high even in winter. After unblocking the soffits and adding a couple of gable vents (and making sure they were sealed properly), temps dropped by about 10-15 degrees and humidity leveled out. Didn’t totally solve ice damming, though. That only improved after I sealed up some gaps around light fixtures and added more insulation above the ceiling. Turns out, a lot of heat was escaping from the house itself, not just getting trapped in the attic.

I’ve heard folks say more vents are always better, but honestly, if you don’t have balanced intake and exhaust - or if you’ve got weird airflow patterns because of the roof shape - it can backfire. And yeah, leaks are no joke if you don’t seal things right. I tried to DIY one vent and ended up calling a roofer anyway after it dripped during a storm.

If you’re on a budget like me, sometimes just improving what’s already there (like clearing soffits or sealing air leaks) gives you more bang for your buck than cutting new holes in the roof. And those sensors are worth it for peace of mind... at least you know what’s actually going on up there instead of guessing.

Totally agree with this. I used to think more vents = better, but after dealing with a weirdly shaped attic and some sketchy old insulation, I realized it’s way more about airflow than just quantity. I had a similar issue with blocked soffits - didn’t even notice until I crawled up there and saw the insulation jammed right against them. Cleared those out and suddenly the attic felt less like a sauna. Still get some ice damming too, though... seems like that’s just part of life with these older houses unless you go all-in on air sealing and insulation. Those cheap temp/humidity sensors are clutch for figuring out what’s actually happening up there.

Had the same thing happen with my place - old insulation stuffed right up against the soffits, blocking any chance of airflow. I spent a weekend just pulling it back and adding those foam baffles. Not glamorous work, but it made a noticeable difference. My attic used to get so hot in summer, and now it’s at least bearable.

I still get some ice dams too, especially after a heavy snow year. I’ve patched up a bunch of little air leaks around the attic hatch and light fixtures, but it’s tough to get everything perfect in these older houses. I looked into adding more roof vents, but honestly, after fixing the basics, I didn’t see much improvement from just adding more holes. Sometimes less is more, especially when you’re trying not to blow the budget.

Those cheap sensors are underrated - mine showed me how much temps swing up there. It’s eye-opening. If I had to do it over, I’d focus on sealing and clearing before spending on anything else.

Seriously, those little temp sensors are a game changer. I stuck one up in my attic last year and couldn’t believe the swings - like, it was hotter than my garage in July. I hear you on the old insulation too. Pulled out a bunch of ancient pink stuff that was basically acting like a dam for airflow. Not fun, but worth it. I’ve tried adding more vents too, but honestly, after sealing up the weird gaps and making sure the soffits could breathe, things improved way more than just punching extra holes in the roof. Sometimes it’s the boring fixes that actually work.

That’s been my experience too. I used to think adding more vents would be the magic bullet, but honestly, just sealing up all those random little gaps around pipes and wiring made a bigger difference than I expected. I did the whole temp sensor thing last winter - mine was just a $12 one off Amazon - and it was wild seeing how fast the attic would heat up on a sunny day, even when it was freezing outside.

I’m in an older house with those classic asphalt shingles, and after pulling out some of that old insulation (looked like it had been there since the ‘80s), airflow improved a ton. Not gonna lie, crawling around up there is not my favorite weekend activity, but it beats paying for roof repairs down the line. I do wonder sometimes if I should’ve gone with blown-in insulation instead of batts, but at least now I know what’s going on up there.

Funny how much you can learn from a cheap sensor and a bit of elbow grease...
