That’s spot on about the fasteners—my neighbor’s roof looked fine from the street, but up close, the screws were rusted to bits after just a few years. I totally get the temptation to save money with galvanized, especially when you’re already stretched thin with coastal property costs. Still, after seeing how quickly the cheaper stuff can fail, I’m starting to think the extra upfront cost for aluminum or better-grade stainless is worth it in the long run. Maintenance only goes so far when the salt’s relentless... tough lesson for sure.
I hear you on the sticker shock for stainless or aluminum fasteners, but after a couple rounds of roof repairs, I’m not convinced the “cheap now, pay later” plan is worth it. My place is about four blocks from the water, and I went with galvanized the first time. Looked fine for maybe three years, then I started noticing brown streaks down the siding—yep, rust from the screws. Tried to stay on top of it with touch-ups, but honestly, the salt air just doesn’t quit.
Second go-round, I bit the bullet and paid for marine-grade stainless. Not cheap, but I haven’t seen a single fastener rust in five years. If you’re already up on a ladder every year scraping and sealing, it’s just not worth the hassle. One thing I’d add: make sure whoever’s installing knows to use the right washers too. I learned the hard way that a stainless screw with a bargain-bin washer still means leaks.
If you’re close to the ocean, shortcuts just seem to come back and bite you. Still, I get wanting to save a buck—just depends how much you like climbing roofs, I guess...
I get the argument for stainless, but I’ve had decent luck with hot-dipped galvanized if I keep up with yearly maintenance. My place is about a mile from the coast, so maybe that extra distance helps. The upfront savings were significant, and I don’t mind touching up every couple years. Not saying it’s perfect, but for folks who don’t mind a little upkeep, it might be a reasonable tradeoff. Stainless is great, just not always in the budget.
I hear you on the budget side—stainless was just too much for me, too. I’m about three blocks from the water and my galvanized stuff started rusting after maybe four years, even with touch-ups. What kind of paint or sealant are you using for maintenance? I’ve tried a couple brands but nothing seems to last more than a season or two.

Honestly, I’m starting to think most of those “marine grade” paints are just marketing. I used Rust-Oleum’s oil-based stuff last year and it looked solid for about eight months, then the rust crept back in around the seams. Are you sanding down to bare metal every time, or just spot prepping? Wonder if powder coating would hold up better, but that’s not exactly cheap either.
