Replacing is usually the way to go, but it depends on the extent of the damage. If it's just minor dents, sometimes you can gently tap them out from behind with a rubber mallet and a wooden block—though aluminum flashing rarely returns perfectly to its original shape.
"Spent hours scrubbing and polishing, and in the end, it still looked wonky from certain angles."
Yeah, polishing won't really help with dents. Aluminum stretches when dented, so once it's warped, you're fighting physics. Replacement sections aren't too expensive anyway, and you'll save yourself a headache.
Honestly, I feel your pain on this one. Aluminum flashing is just one of those materials that never quite forgives you once it's bent outta shape. I tried the same thing last summer—spent a whole afternoon trying to tap out a dent and polish it smooth. At first glance it seemed okay, but as soon as the sun hit it at certain angles... yeah, still wonky.
Like others mentioned, aluminum stretches when dented, so you're kinda stuck with that deformation no matter how careful you are. Replacement sections really aren't too pricey, and if you factor in all the time and frustration saved, it's probably worth biting the bullet and swapping it out. Plus, you'll get peace of mind knowing it's done right.
Still, props for giving it a solid effort—sometimes you just gotta try things yourself to know for sure.

Yeah, totally relate to this. As a first-time homeowner, I'm constantly running into stuff like this and wondering if it's worth the DIY hassle or better to just replace it outright. Aluminum flashing seems especially tricky... is it always this unforgiving? I haven't tackled mine yet, but now I'm thinking twice about trying to straighten out the dents from the previous owner.
Curious though—does anyone know if there's a specific tool or method that professionals use to smooth aluminum flashing without stretching it further? Or is replacement pretty much the standard go-to solution every time? Either way, good on you for giving it a shot. Sometimes you learn more from these little setbacks than from getting it right on the first try.
Honestly, aluminum flashing can be a real pain to straighten out once it's dented or kinked. I've seen homeowners spend hours trying to smooth it out, only to end up with something that still looks pretty wonky. Sure, there are specialized sheet metal tools—like hand seamers or rollers—that pros use to gently reshape flashing without stretching it too much, but even then, it's tricky and takes practice.

Couldn't agree more... but in this case, I'd say replacement usually saves you a headache. Flashing isn't super expensive, and starting fresh gives you peace of mind knowing it's watertight and properly installed. Plus, you avoid the frustration of trying to make damaged aluminum look decent again (trust me, been there).
If you're determined to DIY, though, maybe grab a small piece of flashing and practice first? At least then you'll know what you're getting yourself into before tackling the real thing.
Yeah, aluminum flashing can definitely test your patience. Have you tried using a rubber mallet with a flat surface underneath? Sometimes gentle taps can help smooth out minor dents without stretching the metal too much. But honestly, if it's kinked badly, replacement might save you some frustration. Either way, don't beat yourself up—flashing is tricky stuff, and even seasoned pros have their moments with it...
