Yeah, rock wool's decent but definitely not a silver bullet. Had a buddy who swore by it until he botched the vapor barrier—ended up with a mini rainforest in his attic, lol. Personally, I've had better luck combining rock wool with meticulous sealing and proper venting. Wild weather needs a layered approach anyway; no single product's gonna magically fix everything. Just gotta embrace the DIY grind...and maybe keep a bucket handy just in case.
Totally agree—rock wool alone isn't foolproof. Curious if anyone's tried pairing it with a green roof setup? I've seen some impressive results with vegetation layers buffering extreme weather...might be worth exploring.

I've managed a couple properties that went the green roof route, and honestly, it's been pretty solid. The vegetation layer definitely helps moderate temperature swings and absorbs a surprising amount of rainfall—great for stormwater management. But heads up: maintenance isn't exactly set-it-and-forget-it. We had to deal with irrigation issues during dry spells and occasional weed invasions (nature finds a way, right?). Also, structural considerations are key—make sure your building can handle the extra weight, especially when saturated after heavy rains.
Pairing rock wool insulation underneath could be interesting though...haven't personally tried that combo yet. Might help offset some of the moisture concerns we've run into before. If anyone does give it a shot, I'd love to hear how it holds up over time.
Totally agree on the maintenance side—it's definitely not hands-off. We've had decent luck using drought-resistant sedums and native grasses to cut down irrigation headaches. Also, adding a thin gravel perimeter helped keep weeds from creeping in as much. Haven't tried rock wool insulation either, but we did use a moisture barrier membrane underneath that worked pretty well...might be worth looking into if moisture's a concern.
"adding a thin gravel perimeter helped keep weeds from creeping in as much."
Interesting idea with the gravel perimeter—never thought of that. Does it hold up well during heavy rains or strong winds, though? I'd worry about gravel scattering everywhere. Also curious about the moisture barrier membrane you mentioned... did you notice any issues with condensation buildup underneath? We've had mixed results with membranes, so I'm always a bit skeptical. Still, sounds like you're onto something solid here.
