pressure washer on roof tile or not ?

[Linus_E]

I have to wash the roof and am considering washing it with a high-pressure washer. I've heard both good and bad things about this.

The roof tiles are made of eternit from the 60s...

If I do it now in the spring, it shouldn't matter much since they will dry before the cold comes again...

What do you think?

No. Not asbestos cement. Whether it is flat or corrugated. It will dissolve on the surface and the fibers will spread in nature. Environmental hazard and prohibition.

but what about when it rains then?

oh well.. how do you get the dirt clean...
moss and stuff...
