What are your thoughts on the different kinds of roofing? SE Oakville custom homes have asphalt of course, but there's a decent amount that use metal standing seam, some with metal tiles, I think some with cedar (?) and even a few that seem to use slate (mostly just ultra-high end). I can't think of any that use clay tile, for whatever reason those seem to be very uncommon around here.
I like natural materials, so wood (cedar), stone (slate), clay, and metal.
Asphalt shingles were a sort of invention for the time of the "democratisation" of home ownership following the Second World War. So, cheap, because the explosion in home ownership after the war was amongst people who had no business owning anything and would not have been able to afford owning before it was made easier through government policy. Anyway, they're ugly, cheap, and of low quality in my very extensive practical experience. This is not a subjective opinion, allow me to say.
Clay isn't used a lot around here because it can lead to issues with ice build up and the freeze-thaw cycle. That's why it was used more as an ornamentation for facades whilst roofs were done in slate, for example.
Cedar was the poor man's roof before shingles came along though....I sometimes laugh when wealthy Toronto homeowners get it done instead of slate, say. It's not a very good material as it has a relatively short lifespan compared to slate, metal, and clay.
You simply cannot beat a roof clad in stainless or copper for longevity and functionality.
But even a slate roof is good for well over a century. The problem with the old slate roofs is not the quality of the material used but the fact that in the early 20th century, steel nails were used instead of the long-since standard copper nails.
Steel nails obviously rusting out, causing slate to fall out. Copper nails on the other hand will last longer than the slate they hold.
Most slate should be good for ~120-150+ years.
I've been involved with slate roof refurbishments even where the century old slate is reused and reinstalled with copper nails.
But yeah, shingles are lowest common denominator stuff.
