If you’re still dealing with moisture after the fan install, it might be worth double-checking that the baffles are clear and actually reaching all the way from the soffit to above the insulation.
- Totally relate to the “attic smelled like wet cardboard for weeks” part. Been there, done that, bought the Febreze.
- I always thought baffles were optional... until my insulation turned into a soggy mess.
- Anyone else have trouble finding baffles that actually fit weird rafter spacing? I swear mine are all over the place.
- Curious—did you notice any difference in summer temps after sealing your attic hatch? I’m debating if it’s worth the hassle or just another rabbit hole.

Yeah, baffles are way more important than most folks realize. I’ve seen so many attics where the insulation just clumps up from trapped moisture. As for weird rafter spacing, I usually end up cutting or overlapping baffles—never found a perfect fit either. Sealing the attic hatch did help with summer heat in my place, but it made the attic even stuffier unless the venting was dialed in. It’s a bit of a balancing act.

That’s spot on. I’ve seen people seal up hatches thinking it’s a win, but without enough intake and exhaust, you’re just trapping heat and moisture up there. Solar fans can help, but if the baffles aren’t installed right or the soffits are blocked, it’s just moving hot air around. I always tell folks—ventilation is a system, not a single fix.
Had a similar experience a couple summers back. I figured sealing the attic hatch and tossing in a solar fan would be a quick win for the upstairs heat—ended up with the attic turning into a sauna instead. Turns out, my soffit vents were almost totally blocked by old insulation and some nests I didn’t even know about. The fan was just spinning its wheels, pulling air from inside the house instead of outside.
Once I cleared out those soffits and made sure the baffles were in place, the difference was night and day. Still, I had to keep an eye on humidity up there—one rainy week and I started seeing condensation on the rafters. Ventilation really is a balancing act. It’s tempting to think one gadget or seal fixes everything, but in my case, it took a weekend of crawling around with a flashlight and a lot more patience than I expected.
That’s a classic attic trap—folks add a powered vent and forget that airflow only works if there’s somewhere for the air to actually come in. I see blocked soffits all the time, especially in older homes where insulation’s been stuffed right over the vents. When you noticed the condensation after rain, did you check if your bathroom or dryer vents were dumping moist air into the attic? I’ve found more than a few “hidden” duct leaks that way... Sometimes it’s not just about outside air, but what’s coming from inside the house too.
