I’ve seen those polymer coatings hold up okay on small stuff, but I’m still a bit wary. Maybe it’s just my luck, but I’ve had spots where the rust crept back in under the edge after a couple winters. The fasteners, though—totally agree. I learned the hard way that saving a few bucks on washers means you’re crawling around up there way sooner than you’d like. If you can swing it, stainless or at least coated hardware is worth every penny, especially with all the freeze-thaw we get here.

Man, I’ve been there. Thought I could get away with the cheap stuff on my dad’s shed—ended up chasing leaks every spring. The freeze-thaw here just finds any weak spot. Stainless hardware’s pricey, but it’s saved me so much hassle.

I get the temptation to go cheap, especially when you’re staring at the price tags in the aisle. But after dealing with a couple of leaks in my own place, I’m convinced it’s just not worth it. The first winter here, I used whatever washers were on sale for a quick gutter fix—big mistake. By March, water was dripping right into my mudroom. Ended up spending more on repairs than if I’d just bought the better stuff to start with.
Honestly, I think people underestimate how brutal freeze-thaw can be. It doesn’t matter how “weatherproof” something claims to be if the hardware rusts out or cracks after one season. Stainless isn’t perfect (and yeah, it’s not cheap), but it’s held up way better for me than anything else.
If you’re already up there replacing stuff every year, that’s your answer right there—just bite the bullet and get the good hardware. You’ll thank yourself next spring when you’re not patching things up again.
I hear you on stainless lasting longer, but I’ve actually had good luck with galvanized hardware—at least for green roof installs. It’s not as bulletproof as stainless, but if you use a proper waterproof membrane and keep up with seasonal checks, it holds up surprisingly well. Plus, the cost difference adds up fast when you’re covering a big area. For me, the key’s been layering: membrane first, then hardware, then soil and plants. The plants help buffer hail and temp swings too. Not saying stainless isn’t great, just that there are ways to make other options work if you’re careful about the setup.
Galvanized hardware can definitely hold up if you’re careful with the install and maintenance. I’ve seen a bunch of green roofs where the membrane and plant layers do most of the heavy lifting against hail—plants really do act as a buffer. Still, in spots with constant moisture or where water tends to pool, I’ve noticed galvanized stuff rusts out sooner than expected, even with seasonal checks. Stainless is pricey, yeah, but sometimes worth it for those trouble spots.
I’m curious what climate you’re in? Around here (Midwest), freeze/thaw cycles seem to speed up corrosion on anything that’s not stainless or at least really well coated. But I get the cost concern—on big projects, every dollar counts.
Have you ever had to replace any fasteners after a few years? I’m always torn between saving upfront and having to go back later to fix things... especially when access gets tricky once everything’s grown in.
