That's no real issue and can easily be removed. I quite like to see
a certain amount of lichens on roof tiles. It makes them look more
interesting.....

I agree.


Apparently lichens only grow in places of low atmospheric pollution,

That's not true.


but is the same true about moss?

No.

In fact, are moss and lichen synonymous?

No.
