I've seen flashing tape hold up okay, but yeah, in hotter climates it can get gummy and slip a bit after a few seasons. Flexible gasket's usually sturdier long-term. Curious though, anyone tried sealing primers underneath to boost tape adhesion? Heard mixed things about that...

Yeah, I've tried primer under flashing tape on my porch roof last summer. Quick thoughts:
- Primer definitely improved initial adhesion—tape stuck way better right off the bat.
- But after a year of Texas heat, still noticed some slipping and gummy edges. Not as bad as without primer, but not perfect either.
- Flexible gasket would've probably been better long-term, wish I'd gone that route from the start.
Honestly, tape seems fine for quick fixes or cooler climates, but if you're dealing with serious heat or direct sun exposure, gasket's the smarter bet. Learned this the hard way...rookie homeowner mistake.
Primer helps, but it's not magic. Seen plenty of tape jobs fail after a couple hot summers. Flexible gasket or metal flashing usually holds up way better long-term...especially if you're somewhere sunny. Learned that lesson myself—twice, unfortunately.
Totally agree—primer alone won't cut it long-term. I've seen tape degrade pretty fast, especially in hot climates. Metal flashing is solid, but flexible gaskets can be a lifesaver if your roof has any movement or settling issues. Learned that the hard way when my green roof shifted slightly after a heavy rain season... gasket held up perfectly, tape not so much. Regular checks and choosing the right materials really do pay off over time.
- Good points on the gasket vs tape issue, I've had similar experiences.
- Tape's cheaper upfront, but man, it doesn't last long in harsh weather. Learned that lesson after a storm ripped through here last summer.
- Metal flashing has been my go-to since then—costs a bit more initially, but fewer headaches later.
- Curious though, anyone tried those liquid rubber sealants? Seen mixed reviews online; some swear by it, others say it's messy and unreliable.
- Wondering if it's worth experimenting with or just sticking to what's proven...
