Funny how you can plan a project down to the last detail, and then the attic throws you a curveball. I see this all the time—what looks like a clear run from below ends up being a maze of wires, pipes, or random framing once you’re actually up there. You did the right thing by taking a step back instead of just pushing ahead. It’s tempting to just “make it work,” but that’s where people end up with cut wires or compromised airflow.
When I’m looking at attic installs, I always recommend mapping things out from both sides—outside and inside—before making any cuts. Even then, surprises happen. The bathroom vent thing is a classic one. A lot of folks don’t realize how much those vents rely on clear airflow, and stacking another vent right above can really mess with moisture control in the bathroom. Good catch moving it over.
One thing I’d add: when you’re shifting insulation or moving things around, take a minute to check for any signs of past leaks or rodent activity. Sometimes you’ll find evidence that tells you why something was installed a certain way, or why an area might not be ideal for cutting into. It’s not always obvious until you’re up close.
Honestly, even with all the prep in the world, these jobs rarely go exactly as planned. The key is adapting as you go and not rushing through when something unexpected pops up. Sounds like you handled it better than most would’ve—some folks just plow ahead and end up with bigger headaches down the line.
If nothing else, every project like this adds to your mental checklist for next time... even if it means the “easy” jobs always take twice as long as you expect.
Solar Attic Fan Install Was Supposed To Be Easy... Right?
Man, you nailed it with the “mental checklist” thing. Every time I think I’ve seen it all, the attic throws me a new surprise. Last summer, I was up there trying to run a cable for a security camera and found an old squirrel nest tucked behind some insulation. Never would’ve guessed, but it explained the weird smell we’d been chasing for months. Ended up spending more time cleaning up than actually running the wire.
I totally agree about mapping things out from both sides, but I’ll admit, sometimes I get a little too confident and just eyeball it from below. That’s bitten me more than once—like the time I almost drilled straight into a plumbing vent. You’d think after enough close calls I’d learn, but old habits die hard.
One thing I’ve started doing is snapping a few photos with my phone before I move anything around up there. It’s saved me a couple times when I needed to remember how the insulation or wiring was laid out before I started shifting stuff. Not foolproof, but it helps when you’re knee-deep in fiberglass and second-guessing yourself.
And yeah, those “easy” jobs always seem to balloon. My wife laughs every time I say something will be done in an hour—she knows better by now. But honestly, I kind of enjoy the puzzle of it all, even if it means crawling around in the dust for half a day. At least you end up with a good story (and hopefully no holes in the wrong places).
Funny how the attic always keeps us humble.
Man, you’re not kidding about those “easy” attic jobs turning into a whole ordeal. I’ve lost count of how many times I’ve gone up there thinking I’d be in and out, only to get sidetracked by some mess or weird wiring from the last guy. One time, I cut into a roof deck for a fan install and found an old wasp nest—dead, thankfully, but still made me jump. I’m with you on the photos, though. I started doing that after I re-insulated a section and couldn’t remember where a junction box was buried. Saves a ton of headaches later. Funny thing is, even after years of this, I still underestimate how long these jobs take... guess it keeps us honest.

That hits home. I thought my solar attic fan would be a quick weekend project—just pop it in, wire it up, done. Ended up crawling around for hours because the previous owner had left a maze of old speaker wires and random insulation patches. Had to trace everything just to make sure I wasn’t cutting into something important. The photos idea is gold, though. I started labeling stuff with painter’s tape too, but half the time it falls off in the heat. Maybe I’m overthinking it, but I’d rather spend an extra hour double-checking than pay for a mistake later.

That’s honestly the right call, especially in attics where you never know what’s hiding behind insulation or old wiring. I’ve run into similar messes—sometimes it feels like every attic has its own “surprise” left by the last owner. I usually use a Sharpie to mark rafters or junctions instead of tape, but even then, heat and dust can make things tricky.
Did you run into any issues cutting the roof deck for the fan? I always get a little nervous about hitting a rafter or ending up with a weird gap. Some folks use a hole saw, but I’ve seen others just go at it with a reciprocating saw. Curious if you found one method easier, or if it was just trial and error.
