Have you EVER seen a house with white shingles? Beige? Light Yellow?

If this is such a good idea, why hasn't someone done it?

The reason is the roof looks ghastly after but a short while from
deposited air pollution.

In Rome, where they have a lot of public sculptures, there are
traveling pressure-washer crews that do nothing but blast the soot
(and pigeon ****) off all the statutes. The Vatican has its own
full-time crew for just that purpose.

The only place where you'll see a light-colored roof is somewhere
where you CAN'T see it, like the flat roof of a commercial building.

Or in places like New Mexico where the extreme heat and arid
conditions work against the mildew that causes the discoloration. See
my response in this thread about not being able to find white
shingles.

Ah, right. The environment is a significant factor.
