Switched to metal panels a few years back, and honestly, the noise isn’t as bad as folks warned me. Maybe depends on attic insulation?
I’ve had the same experience with metal—folks always say it’s going to sound like a drumline in a thunderstorm, but with decent insulation and an attic that’s not just open rafters, it’s really not that dramatic. I think a lot of it comes down to how much air gap you’ve got between the panels and your living space. I put in R38 batts when we did our roof, and that made a big difference.
That temp swing you mentioned is real, though. Metal reflects heat, but once it gets hot, it radiates down pretty fast if there’s not enough ventilation. We ended up adding a solar attic fan last summer, and it actually dropped the upstairs temp by about 3 degrees on those brutal July afternoons. Not a miracle cure, but it helped.
Rubber roofs are interesting—I looked at them for our garage. Sound-wise they’re great, but like you said, anything overhanging will scuff them up quick. I saw some folks online using sacrificial mats under trees just to keep the worst of the gouges away. Not sure if it’s worth the hassle unless you’ve got a ton of branches overhead.
My dog still hates storms, but at least I don’t have to patch leaks every spring... trade-offs, I guess.
Trade-offs is right. My old asphalt shingles were a constant patch job every spring—never failed, always some sneaky leak around a vent or flashing. Metal cost more up front (almost double what asphalt was quoted), but honestly, not having to budget for repairs every year has made up for a lot of that pain.
If you ever want to tweak the temp swings upstairs, check your attic airflow first—ridge vents or gable fans can go a long way without breaking the bank. And for what it’s worth, my dog still hides under the bed when it rains too... some things just don’t change no matter what roof you put on.

That’s fair, but I still wonder if folks overlook green roofs too fast. I put sedum trays on my shed and, yeah, it was a project, but it’s been super low-maintenance and keeps the inside temp way more stable than the metal on my main house. Not for everyone, but the insulation is wild—barely notice storms or heat swings. The upfront cost was in the same ballpark as metal for me, but I get some nice shade and pollinators out of it too. Just tossing it out there since most people skip right past living roofs.
Green roofs are definitely interesting, but I’d be careful jumping in on a larger scale without factoring in the structural load. Most residential roofs aren’t designed for that extra weight, especially once you add saturated soil. I’ve seen a few projects stall out because the engineering costs ballooned. Metal’s more predictable for most properties, at least in my experience. That said, for sheds or flat roofs, I can see the appeal—just not sure I’d risk it on a main house unless it was built for it from the start.
That’s exactly what tripped me up when I first started looking into green roofs. I thought it’d be a cool way to add some insulation and maybe grow a few herbs, but the moment my inspector mentioned “load calculations,” I realized my 1960s ranch wasn’t up for it. Ended up going with a basic shingle replacement instead. Maybe if I ever build a shed out back, I’ll try the green thing there... but for now, just keeping water out is enough of a project.

Yeah, I ran into the same wall. My house is late 50s and the joists just aren’t beefy enough for anything heavier than asphalt shingles. I actually had an engineer buddy look at it—he laughed and said, “You want to put a garden up there? You’ll have a garden in your living room.”
I get the appeal of green roofs, but unless you’re building new or doing some serious retrofitting, it’s a tough sell for older places. Shed idea sounds way more doable. I did a little “living roof” on my chicken coop last year—just sedum mats and some lightweight soil. It’s held up through two winters so far and honestly, it was way less hassle than I expected.
Waterproofing is definitely underrated. After chasing leaks for months, I’m convinced keeping things dry is half the battle. Green roofs can wait until someone else is footing the bill...
