Getting the roof coated

A couple of weeks ago our roof was covered in moss and was the worst looking roof in the street. Dad was considering entering a job on RatedPeople.com when out of the blue a guy knocked on the door asking to quote for doing the roof! The timing was bizarre but perfect. We are getting the roof cleaning, tiles mended or replaced and the whole thing coated so as to prevent moss returning. Now it's the best looking roof in the street!
