I’ve managed a few properties with stone-coated metal, and I’d actually push back a bit on the heat thing. In my experience, the attic insulation and ventilation make a bigger difference than the roofing material itself—especially in direct sun. One building had both bare metal and stone-coated sections, and honestly, the temp readings inside weren’t that far apart once we factored in proper airflow. Moss is definitely an issue in shaded spots, though. We’ve had to pressure wash every couple years, even with “algae-resistant” coatings. Not a dealbreaker, but it’s something to budget for if you’re in a damp area.

That lines up with what I’ve seen, especially in hotter climates. I’m curious, though—when you’re thinking about wildfire risk, do you find the moss buildup on stone-coated metal ever becomes a fire hazard? I know it’s not super flammable, but I’ve read that organic debris can sometimes catch embers. Wondering if anyone’s actually seen that happen or if it’s more of a theoretical risk.
I’ve wondered about that too, actually. We just bought our place last year and the inspector pointed out some moss on the north side of our metal roof. He didn’t seem too worried, but I started reading up on fire risk (paranoid first-timer here) and saw a few warnings about dry moss or leaves catching embers.
Honestly, I haven’t seen any real-life stories where moss itself started a fire, but I guess if it gets thick enough and dries out, it could be like tinder? The bigger issue for us has been all the pine needles that collect in the valleys—those definitely seem sketchier than moss. I spent a Saturday up there with a leaf blower and felt like I was prepping for some weird reality show: “Will It Burn?”
Anyway, I’m not convinced moss is a huge hazard unless you let it get out of control, but the debris buildup is probably worth keeping an eye on. Still learning as I go...
I get why you’re not super worried about moss, but I actually think it’s riskier than it looks—especially on a metal roof. Where I am (PNW), we get these dry spells and the moss goes from squishy to crunchy fast. I’ve seen patches flake off and pile up in gutters, which is basically kindling if an ember lands there. Pine needles are definitely bad news, but I wouldn’t write off moss either. It’s sneaky... doesn’t look like much until you realize how much is hiding under the edges or around vent pipes. I’d rather spend an hour scraping it off than wonder if it’ll be the weak link during fire season.

That’s a good point about moss being “sneaky.” I didn’t realize how much could pile up until I started poking around my own gutters. Metal roof here too, and honestly, the stuff just hides everywhere. Not as easy to ignore as I thought...
