Tape is just my “oh crap” solution when I can’t get to a real repair before winter sets in.
That’s pretty much how I see it too. I’ve tried layering tape under flashing on a couple of jobs, thinking it’d be a nice backup, but honestly, it’s never as watertight as I’d hoped. Once had a spot behind a dormer where the tape actually trapped moisture and made things worse. These days, I focus on getting the flashing lapped right and use a good polyurethane sealant in the tricky corners. Tape’s fine for a quick patch, but for anything long-term, I’d rather trust the metal and caulk combo.

Yeah, I’m with you there. I’ve tried to stretch tape fixes longer than I should’ve, mostly because I didn’t want to shell out for new flashing right away. It always comes back to bite me—either the tape peels up in the cold or, like you said, it traps water and makes a mess. I had a spot over my porch where the tape actually made the wood underneath start to rot. Lesson learned.
I get why folks use it in a pinch (especially when winter’s coming and you just need something to hold), but if you can swing it, replacing the flashing and sealing up with a good caulk is worth it. The upfront cost stings less than dealing with water damage later. Still, sometimes you gotta do what you gotta do... just don’t trust that tape for more than a season or two.
Had to laugh reading this—last fall I slapped some tape over a gap in my flashing, thinking it’d get me through till spring. Fast forward to February, and I’m up there with a hair dryer trying to get the tape to stick back down in 20-degree weather. Not my proudest moment. Metal and caulk’s a pain up front, but at least you’re not chasing leaks every time it rains. Tape’s like putting a Band-Aid on a leaky pipe... works until it doesn’t.
Been there with the “temporary” tape jobs… they always seem to turn into a winter project. I swear, every time I try to save myself some hassle, I end up doing twice the work in worse weather. Metal and caulk’s a pain, but at least you’re not up there in February with frozen fingers and a roll of tape.

Man, that hits home. I’ve patched more than a few leaks with “just for now” tape, thinking I’d get back to it before the cold set in. Next thing you know, it’s January, the wind’s howling, and I’m up there cursing my past self. Metal and caulk can be a pain, sure, but at least you’re not fighting with tape that won’t stick because your hands are numb. I’ve learned—if you can swing it, just bite the bullet and do the proper fix before winter. It’s never as quick as you hope, but it beats the alternative.
