nice to have smething growing down from the moss covered roof. Any
ideas?

Have googled extensively but can find no reference to a plant
called 'smething'

Probably because you didn't press the "Any" key.

But regarding the planting, I'd forget trying to have something growing
down from the roof, nothing for it to root into and to get feed and
water from.
You could however put a row of troughs along the edge of the roof and
grow hanging plants such as trailing geraniums, nasturtiums etc. over
the summer months but remember you will have to block the lower side to
keep the troughs upright, and they will need frequent watering.
