Roof cleaning - pointless?

[Grandfit]

Not sure if this is just a local fad, but we seem to have a number of houses locally having their tiled roof cleaned. Taking them from a nice weathered brown, to bright clay orange.
I assume this is purely an aesthetic fad?
Perhaps it's just a personal preference, but not quite sure why someone wants to take a well weathered 1930s roof and make it look like a new build. I thought the general advice for clay tiled roofs was if it's not broke, don't touch it.

It does seem to be a growing trend, but you're right that many experts advise leaving clay-tiled roofs alone if they’re not causing any issues. The weathered look actually helps protect the tiles and adds character to older homes. Cleaning a roof purely for aesthetic reasons can sometimes do more harm than good, as it may damage the tiles or reduce their lifespan. While some people may prefer a brighter, “new build” look, it’s generally recommended that if the roof isn’t broken or in need of repair, it’s best to leave it as is.
