Yeah, the venting thing is easy to overlook until you’re staring at a soffit that smells like a gym bag. I’m with you on the cellulose—used it in my last place and it handled the weird corners way better than fiberglass ever did. Still, I’m a little wary of “smart” vapor barriers. Maybe I’m old school, but I’ve seen them work... and not work, depending on how fussy the install was. Sometimes feels like you need a PhD just to keep your attic dry.

Man, that hits home. I’ve had my share of “science experiments” up there. I get the hesitation with smart vapor barriers—they’re great when installed perfectly, but who’s perfect? Sometimes I think a well-detailed old-school poly is less risky if you know your climate zone. But hey, cellulose for the win on those weird angles.
I hear you on the “perfect install” thing—one missed staple and suddenly you’re chasing moisture for years. I’ve seen poly work fine, but in some climates it just traps more than it helps. Smart barriers are cool tech, but yeah, not exactly forgiving if you mess up. Honestly, I lean toward cellulose too, especially in those oddball spaces where batts just don’t fit right. Sometimes simpler really is better... at least until the next building code update.
Totally get where you’re coming from—sometimes the “latest and greatest” just adds more headaches. I’ve had good luck with cellulose too, especially in those weird angles nobody wants to crawl into. It’s not fancy, but it works, and sometimes that’s all you need.
I hear you on cellulose—definitely a solid choice for those awkward nooks and crannies. I’ll admit, I’m a bit more methodical when it comes to roof replacements, though. If you’re dealing with leaks, I’d start by mapping out exactly where the water’s coming in. Sometimes it’s not even the roof itself but flashing or vent boots that have failed (ask me how many times I’ve chased a “roof leak” that turned out to be a cracked vent pipe...).
Once you’ve got the culprit, I’d recommend stripping back to the decking in that area and checking for rot. No sense putting new material over compromised wood. For insulation, cellulose is great for retrofits, but if you’re already opening things up, rigid foam panels can give you a tighter seal—just depends on your budget and how much hassle you want.
One thing I’ve learned: don’t get too caught up in fancy products unless there’s a clear benefit. Tried-and-true methods usually win out in the long run, especially if you’re not looking to reinvent the wheel. Just my two cents—sometimes boring is best.
