Tape as a stopgap is pretty much how I’ve handled it too, especially when the weather’s closing in and I can’t get to a full replacement right away. For me, it bought maybe a season—if that—before it started peeling back. If you go this route, pressing the tape down hard on a super clean, dry surface helps, but yeah, it’s still a pain to scrape off later. I’d say it’s worth it if you just need to keep water out for a few months, but don’t expect miracles. Sometimes it just delays the inevitable, but it can save you from interior damage while you line up a proper fix.
Tape’s better than nothing if you’re in a pinch, but honestly, I’ve never seen it last through a full winter—especially if you’re in a spot with big temp swings or lots of rain. Even the high-end flashing tapes start curling on rough or uneven surfaces. I get the appeal when you just need to buy time, but I’d rather see folks use a temporary metal patch with some roofing cement if they can swing it. Messy, sure, but at least you’re not peeling off gummy residue later.
One thing I learned the hard way: if you let that “temporary” tape job go too long, water can still sneak in around the edges and you end up with rot or mold inside the wall. That cleanup is way worse than just fighting with the tape.
If you’re forced to use tape, maybe check it every couple weeks, especially after storms. But yeah, it’s just a band-aid. Aluminum flashing’s not that pricey to replace, and you’ll sleep better once it’s done right.

That’s the nightmare, right there. I tried the “just for now” tape trick on my shed last fall—figured I’d get to it before winter. Fast forward to spring, and I’m scraping off black gunk and cursing my own laziness. Lesson learned: tape buys you a little time, but not much. If you can patch with metal and some goop, even if it’s ugly, you’re way better off.

That’s the truth. I’ve seen so many “temporary” tape jobs turn into permanent headaches. If you spot a flashing issue, here’s my usual routine: peel off the old tape, dry everything out, then cut a patch from scrap aluminum. Slap on some exterior sealant, screw it down, and you’re golden. Might not win any beauty contests, but it keeps the water out. Tape’s fine for a weekend, but after that… you’re rolling the dice.
- Tape’s cheap, but I’ve had it peel up after a couple storms.
- Did the aluminum patch thing last fall—held up way better than I expected, even through winter.
- Anyone tried those rubberized flashing patches? Wondering if they’re worth the extra few bucks or just another gimmick.
