dont think it will work on a roof that is not under water. I thi nk it all the algea dies and sinks to the bottom, then the vac sucks it up and its out of the pool. It would also cost alot of money to treat a roof with that, But i might be wron g

I think these little critters need a moist environment to survive, but since moss & algae also like moist environments It could be ok. The moss / algae dose not sink to the bottom of the water in the case of the pool demo, the little critters eat it and fart the gasses out basically, when there is no more to eat they die. they use it on commercial kitchen floors to eat grease and dirt, drains, concrete surfaces etc
any way just put it up for you to look at always looking for more enviro friendly ways of doing things, the less chemicals I have to work with the happier I am
It gets so hot here in Texas, the enzymes might die of heat stroke or dry out before doing their job. hahahahaha j/k
