When did you last have your roof cleaned? The idea of needing to clean one’s roof had never even entered our heads before living in France. At least two of our neighbours have had their rooves cleaned. There was no moss or any particular problem, but the job required a young man to climb 10 meters from the ground, spray on a product to loosen the dirt, clean that off and then coat the roof with something that would protect it. When I asked why they needed it done, it was an ‘Il faut le faire’, moment. It must be done! (See MUST)
