A line would run across peak of roof with holes in it to spray water out on to roof ,a pump and dispenser for moss killer at ground level . Turn it on once a week or so and no Moss whould have a chance!!

       Add a bit of copper chloride, and you've got something that will work. It will also kill a number of plants located directly beneath your eaves. Plain water will only increase the likelihood of moss growing and harming your shakes.   

       Alternatively, a copper ridge-cap will solve the problem without affecting your electric bill.

       The DIY version involves a length of electrical cable with the insulation stripped off. It woiks surprisingly well.

       More copper, I think, Angel. Or were you proposing an Aluminum wire solution?

       No, I was just suggesting an alternative (cheap!) source of copper.

       [thumb]: Shame on you for suggesting such a thing! Actually, when I rewired part of my house I realised about £30 from the scrap copper.
Truro Cathedral has a copper roof, so I don't think lightning is likely to be too much of a problem. Having said which, Truro Cathedral also has a lightning conductor.

       Bump.   

       I just had this same idea today, seemed “new to me” - but I searched HB and see it here. Surprised that for all the annos nobody linked information on existing real-world implementations.   

       My implementation was just going to have it spray water for a few seconds, every hour, every day - not just for moss but other crud that accumulates on the roof. I’d only add roof cleaning chemicals occasionally. And it could be optionally turned on to a constant flow during fire-risk season.   

       Seems like someone must have done this somewhere - or is there really a fatal flaw to the idea?

       But, I like moss on roofs.

       The dispenser could be filled with moss nutrient.
