"Most issues I see aren't really about the material itself but more about poor installation or lack of maintenance—like debris buildup causing moisture to linger."
Yeah, this makes sense. I'm pretty new to homeownership and just dealt with some flashing issues myself. Turns out the previous owner never cleaned the gutters, so leaves piled up and trapped moisture against the aluminum flashing. Once I cleared everything out and patched a couple small spots, it was fine. Copper looks nice, but honestly, regular upkeep seems way more important than fancy materials...
Totally agree that upkeep matters more than material choice. But I'm curious—did you check if the flashing was properly angled after clearing the debris? I've noticed sometimes even minor shifts or bends can cause water to pool again pretty quickly. Had a similar issue myself, and just cleaning wasn't enough until I adjusted the slope slightly. Aluminum's fine, but installation details seem to make a huge difference...
Good point about the angle—it's easy to overlook. Did you also check if the flashing edges are still sealed properly? I've had situations where the slope was fine, but tiny gaps or worn sealant let water sneak underneath. Ended up having to reseal a few spots after cleaning and adjusting the angle. Aluminum holds up pretty well overall, but those little details can make or break it...
"tiny gaps or worn sealant let water sneak underneath"
Exactly this. Had a similar issue last year—thought the slope was the culprit, but turns out it was just old sealant cracking. Quick reseal job saved me from a bigger headache down the line... aluminum's tough, but details matter.
Had a similar experience, but honestly, resealing was just a temporary fix for me. Thought I'd solved it, but after a heavy storm season, water found its way back in. Ended up pulling the flashing completely and redoing it properly—bit more hassle upfront, but haven't had an issue since. Aluminum's solid stuff, sure, but relying too much on sealant alone can be risky...
