      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.
