- Been there with the emergency tape jobs. Sometimes you just need something to hold through a rough patch, especially if the weather’s not on your side.
- I’ve had mixed results—guess it depends on the brand and how desperate I was. One winter, I slapped some tape on a leaky gutter joint, and it lasted way longer than I expected. Still, I always keep in mind it’s just a band-aid.
- Totally agree about needing a dry surface. In my experience, even a little moisture under there and you’re asking for trouble later. Once spring rolled around, I pulled it off and found some corrosion starting up... not ideal.
- For anyone dealing with older flashing, sometimes you don’t have much choice but to patch and wait for better weather or more time. Just don’t forget about it—set a reminder or something so you actually go back and fix it right.
- Long-term, nothing beats pulling the flashing and redoing the seal or swapping out the damaged bit. But yeah, life gets busy. Quick fixes have their place.
Funny thing—I once used duct tape in a pinch after running out of proper flashing tape. It held for a week until we got hit by a storm... then not so much. Lesson learned.
Anyway, sounds like you’ve got the right idea: patch when you must, but don’t trust it forever. Aluminum’s tough but not invincible.
That corrosion under the tape is exactly what I see all the time—traps moisture, then you’ve got a bigger headache. Quick patch is fine if you’re in a bind, but I always tell folks: as soon as you can, pull it off, dry it out, and do a proper reseal. Otherwise, you’re just buying time... and sometimes not much of it. Duct tape on flashing? Seen it more than I’d like to admit. It’s like putting a band-aid on a leaky dam—works till it doesn’t.

Couldn’t agree more with this. I’ve lost count of how many times I’ve peeled back tape and found the aluminum underneath looking like it spent a week at the bottom of a lake. Quick fixes have their place, but they’re just that—temporary. I get why people reach for duct tape in a pinch (especially when rain’s coming in sideways), but it’s almost always a short-term win and a long-term loss.
One thing I’ll add: even the “proper reseal” can go sideways if you don’t let everything dry out first. I’ve seen folks slap sealant over damp metal, thinking they’re ahead of the game, but all that does is lock in the moisture and speed up the corrosion. If you can, give it a day or two of dry weather before you patch things up for real.
Not saying I haven’t been guilty of a quick patch myself when time was tight... but every time, I end up regretting it later.
Had to laugh at the “band-aid on a leaky dam” bit—been there, done that. I once used Gorilla tape in a panic and it held for about two weeks, then the whole mess peeled off in one piece after a storm. Lesson learned: shortcuts just make more work later. Letting things dry out is key, but sometimes the weather just doesn’t cooperate and you end up playing whack-a-mole with leaks.

That’s the truth. I’ve tried every quick fix in the book—tape, caulk, even plastic sheeting once. Always ends up being temporary, especially with aluminum flashing. If water gets behind it, you’re just delaying the inevitable. It’s a pain waiting for things to dry out, but forcing a repair in damp weather never worked out for me. Sometimes you just have to bite the bullet and redo it right, even if it means living with a drip for a bit.
