This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?
Just post some stuff and don't spam.
I've ripped off my fair share of pitch and gravel roofs, that's definitely not the kind of stone you'd normally use (but it could still be). When you see granules or rocks on a roof, it's usually meant as a heat sink to stop the tar or shingles from cracking and degrading. Otherwise, I've also ripped off slate roofs, and they used lead wide head roofing nails, though at some point they had just tarred over the whole thing, and eventually we put basic ashpalt shingles on it.
This guy roofs.
He's clearly a dog.

No. Roof.

As much as I respect the standard 3-tab, I'm more engaged by the high-albedo options.
I...what is this fresh language you speak
It's roofer speak. Standard asphalt shingle is properly called architectural 3-Tab. High-albedo means that the roof material is highly reflective, which has a bunch of benefits in terms of environmental applications.
This is not a flat roof though, it's sloped.
That size was a style back in the day. The house my dad built in the late 50s had one. I believe they were often lava rock.
Pitch of that roof would need a membrane under shingles, no?
Depending on where you live in the American southwest, that’s the norm. Shingles are weird.
This is in central Saskatchewan. Presumably those southwest roofs are flat - this isn't.
Low slope, so considered flat for most codes, can’t use shingles. Basically every commercial roof has rocks, but In the last decade they’ve shifted to a vinyl. Lighter, handles more snow load.
They probably could use shingles, there are plenty of surrounding houses with about the same pitch that do.
From one to next they look really similar.
2:12 is low slope iirc. So 3:12 can use shingles, but not 2:12.
You’re right though, could just be a look choice on a higher slope. Could be a “trial” roof or something who knows.
Weird. I would assume that rocks would be problematic for snow and would just encourage snow to stick and add street to the framing.
The only rock roofs I’ve ever come across are in temperate places that don’t get snow.
On metal roofs they actually add grips so the snow can’t slide right off.
A sheet of snow isn’t light, you DO NOT want that sliding off and hitting you, but it’ll also fuck your eavestrough up.
"Eavestrough" is some hardcore Midwest levels of dialect
Canadian, eh?
Michigander, so close enough.
Slate shingle roofs used to be the norm.
Not in this part of the world though.
But slate is flat and can be overlapped. How would this even work?
you see this all over Europe with clay roofs, they put large rocks to weigh down the tiles to prevent winds from lifting them. But, usually just around the edges of the roof.
Ok that makes way more sense.
Doubt it, thatch and wattle and daub are the norm. Slate needs to be mined, it doesn't just grow near you.
Yes and in some parts of the world it's really easy and cheap to mine surface slate.
I grew up in Phoenix in the early 80s and I saw many of these.
Saw something similar to this in Tempe last year, but I didn't see any lawns like this in the area, I don't think I saw much of any green the 3 weeks or so I was there.
Weird. I a few months ago I stumbled upon two mid century apartments in my town that both had rock roofs.
I wonder OP’s roof didn’t used to be painted.

It's not instead of shingles, that's a tin roof instead of shingles. This is a design aesthetic.
Souns like I'd go deaf at the thought of rain.
A tin roof sounds absolutely wonderful in the rain. My cottage has one.
Hot rocks in your area

Phar out. I wonder what they use for waterproofing?
I wonder how they get them to stay in place. It's not a steep slope, but it's definitely not a flat roof. So far I have resisted the urge to ring the doorbell and ask about the roof.
They must have used some type of resin/ epoxy.
They use tar.
You would think the tar would ooze downward on very hot days. (Yes, we get them here.)
The gravel stabilizes the tar somewhat. But yes. And gravel washes off the roof too. And then the roof leaks the next time you get rain. They're typically initially installed with hot asphalt and then patched with tar until the homeowner gives up and buys shingles. There's a good reason you don't see gravel roofs very much.
The roof in the picture isn't just gravel, it's got fist size rocks in it as well. Gravel alone I could understand.
EPDM is the most common material for modern rubber/stone roofs in commercial applications.
