Hi
My house is a detached built in 1993. While I clean the gutter, there are always some granules (brown sand-like stuff). I think they are washed down from the roof tiles (double Roman tiles maybe?) by the rain. The slope of the gutter is not so good hence there is always some standing water and these granules.
My question is, are the tiles supposed to lose granules like this? What is expected life span of tiles?
many thanks for any reply.
