"Better to bite the bullet now and redo it properly—saves you from climbing back up there every few months."
I get where you're coming from, especially with aluminum being sneaky about corrosion. But do you think galvanized steel is always the best alternative? I've seen situations where galvanized steel starts rusting quicker than you'd expect, especially in coastal areas or places with heavy rainfall. Sure, aluminum can corrode quietly, but steel isn't immune either—it's just more obvious when it happens.
Have you ever considered copper flashing instead? Yeah, it's pricier upfront, but it lasts forever and develops a protective patina over time. I had a customer who switched to copper after multiple headaches with aluminum and steel, and they've been super happy since. Just something else to think about before committing fully to galvanized steel...
Good points about copper—I've seen it hold up impressively well, especially in older homes. But one thing to keep in mind is compatibility with existing materials. Copper can react negatively with aluminum or galvanized steel if they're touching directly, causing galvanic corrosion. You'd definitely want to use some kind of barrier or separation material. Just something to consider before making the switch...
Totally agree on the galvanic corrosion point—learned that the hard way when I first moved in and thought I'd DIY some flashing repairs. Thought copper would be a classy upgrade until someone mentioned the whole "metal drama" thing. Ended up using a rubberized asphalt barrier tape between the copper and aluminum, worked pretty well so far. Just something to keep in mind if you're set on copper. Plus, it gave me an excuse to buy more tools...which is always a win.
Good call on the barrier tape—I had a similar experience a couple years back. Thought I'd save some cash and just patch up the aluminum flashing with whatever was handy...ended up mixing metals without realizing it. A few months later, corrosion city. Lesson learned, now I always double-check compatibility. Rubberized asphalt tape is a lifesaver, though—easy to apply and holds up surprisingly well. Plus, fewer headaches down the road.
Glad you mentioned the rubberized asphalt tape—I've heard good things but haven't tried it myself yet. Does it hold up well in extreme weather, like heavy snow or intense summer heat? I've been burned before by products that promise durability but then peel off halfway through winter... Also, is it easy enough for someone who's not exactly a DIY pro? I'm decent with basic fixes, but if it requires surgical precision, I might be in trouble, haha.
