roof cleaning

Hi, this is a house in Edgbaston Birmingham UK which has a sloped roof. The roof has not been cleaned for a number of years and there is spots of moss growing on it. I need someone to climb onto the roof and clean off the moss with a stiff broom. Sloping ladders will be needed and some safety equipment. The gutters will then need to be cleaned to ensure the drains are not blocked. This should be a days work for a couple of people. Thanks for considering this job
