Roofing near the ocean—did you know salt air eats metal?

You nailed it—green roofs sound great on paper, but the logistics can be a beast, especially near the ocean. I tried something similar on my place (not as big), and the waterproofing alone kept me up at night. The maintenance is no joke either. Still, I get why folks are drawn to the idea. If you ever revisit it, maybe start small—like a test patch or something.

I get where you’re coming from, but honestly, I've seen green roofs hold up surprisingly well even near the coast—if you’re picky about materials and drainage. That part about waterproofing keeping you up at night?

—yeah, that's real, but sometimes I think folks overcomplicate it. I helped a buddy install a sedum patch on his garage, and after three years, no leaks, no salt damage, just some weeding. Maybe it’s about scale and not going too wild with plant choices. Maintenance is still a thing, but it’s not always a nightmare.

That’s encouraging, but I wonder if the smaller scale makes a big difference. Did you use a root barrier or just rely on the membrane? I’ve seen some folks skip that step and regret it later. Curious if you noticed any issues with fasteners or flashing corroding over time—salt air seems to find every weak spot.

We did the root barrier—my buddy's pretty paranoid about stuff growing where it shouldn't. It was just a thin layer, nothing fancy, but I think it made a difference. I’ve seen a few jobs where folks skipped it and, yeah, roots started poking through the membrane after a couple years. Not a fun patch job.

On the salt thing, we used stainless fasteners and aluminum flashing, but even then, I noticed a bit of white corrosion on the flashing edges after the first winter. Nothing major yet, but you can tell salt air is relentless. I grew up a few blocks from the beach and my parents’ old shed roof basically dissolved after ten years—galvanized nails just turned to powder.

Small roofs probably get away with more, but if you’re anywhere near the ocean, I'd say overkill is just standard practice. Skimping on materials is like begging for leaks and rusty bits.

Man, salt air is just brutal, right? I used to think stainless was the magic bullet too, but even that stuff gets a little crusty after a while. Makes you wonder if anything actually lasts out there. I’ve seen folks try to save a few bucks with regular nails and it’s like, why bother? Might as well just sprinkle rust flakes on your roof from day one. You’re spot on about overkill—near the ocean, it’s just called “doing it right.” Ever tried any of those fancy coatings or is it all just delaying the inevitable?
