Has anybody any experience of having their roofs pressure washed?
Ours is a 70's house with concrete tiles and is covered in moss etc.
I was keen to get it cleaned this spring as the moss fall out around
the house is getting worse. However Im not sure how damaging
this process can be, and if a good stiff brush is better? Although I
a pressure washer I would have somebody else do this as Im not keen
on climbing over a roof. Any idea of cost?
