I've searched and read all the posts I can find about this and the general consensus seems to be don't.
So, I recently bought a 1930's end terrace. The roof is red Rosemary clay tiles, the originals I'd say. A builder has moved in next door - a tenant I think so I'm a bit puzzled about his plans. He says he's going to jet wash his roof and seal it, didn't say with what. The terrace is a row of four, the end two (mine and the other end) aren't very mossy at all. The centre two (his and his neighbour other side) have a bit more but not what I'd call bad in my strictly non-professional opinion. We're on top of a windy hill so the roofs are regularly blasted by the wind and rain.
I think he's a decent person and would probably offer to do mine at the same time but I'm a bit concerned about the process based on what I've read here. My loft is currently dry. Is cleaning and sealing likely to significantly extend the life of the roof and is it likely to do any harm?
Grateful for any thoughts.
