I hear you on the freeze/thaw cycles—I'm in the upper Midwest too, and that’s where I’ve seen the most issues. Galvanized fasteners on my porch roof started showing rust after about three years, especially near the gutter where water pooled. Ended up swapping those out for stainless, even though it hurt the wallet a bit. If access is tough, I’d rather pay more up front than fight with corroded screws later. Still, for spots that stay drier, galvanized has held up just fine for me. The tricky part is predicting where the trouble spots will actually be...
Predicting those trouble spots is always a headache, especially with our weather swings. I’ve seen gutters and valleys go first—anywhere water lingers or snow piles up. Stainless is pricey, but like you said, it’s worth it if you don’t want to mess with replacements in tight spots later. Sometimes I’ll use a mix: stainless for the high-risk areas, galvanized everywhere else. It’s not perfect, but it keeps costs down and headaches to a minimum. Funny how the “dry” spots can surprise you after a rough winter...

Right? I swear, the spots I thought were totally safe ended up with the worst rust streaks last year. It’s like the roof has its own secret water routes nobody tells you about. I get the mix-and-match approach—stainless where it matters, galvanized for the rest—but sometimes I wonder if we’re just playing whack-a-mole with leaks.
Ever tried any of those recycled rubber or green roof patches in the valleys? I’ve been experimenting with them on my shed (not brave enough for the main house yet). They’re supposed to help with runoff and insulation, but I’m still waiting to see how they handle hail. Not sure if it’s genius or just another thing to babysit.
Anyway, I’m with you on stainless being worth it in the worst spots, but man, that price tag stings. If only roofs came with a “trouble spot” map...
Funny you mention that—last spring I patched a spot I thought was cosmetic, then a random “dry” corner started dripping after the next storm. I haven’t tried the rubber patches yet, just those cheap aluminum tapes. They held up okay, but hail still left a dented mess. Stainless is great, but yeah, my wallet cries every time I price it out. Sometimes I think my roof’s just trolling me at this point...
Yeah, those aluminum tapes are a mixed bag. I used them on a seam over my porch—looked fine until the first big hailstorm, then it was all crumpled and half-peeled. Tried a rubber patch kit last fall and it’s holding up better so far, but nothing’s perfect. Stainless is tempting, but man, the price tags make me wince every time too. Sometimes I swear the roof waits for payday to spring a new leak...
