Ultra-white ceramic cools buildings with record-high 99.6% reflectivity::undefined
NightAHawkinLight on youtube has been working on something similar. same kind of snow-like nanostructure to reflect light away, but with the added benefit of a paint that emits light in a wavelength that travels through the atmosphere without interacting with any of it.
so if you point a painted tile at the sky it will actually cool below ambient temperature, it’s pretty wild www.youtube.com/watch?v=N3bJnKmeNJY

You know what also cools houses down super efficiently?
Trees

Excellent - how many trees can I grow on my roof? Can they be retrofitted?

Is your roof flat? Many. /s

Trees? Not many. Grasses, herbs, wildflowers, and shrubs? Tons of them. And you can pretty easily retrofit over an existing sloped roof. And the weight is no more than a tiled roof.

Kind of
There are eco apartments (planning idk about practice); grass on the roof and trees growing up the side
Lakehead University Orillia was going to do this but I don’t know if they have

You know what cools down roofs and generates electricity? Magic!

What about Ultra white ceramic trees?

True though this is still practical for folks who live in deserts and other treeless places

but trees look gross
