water pooling on roof

[iaink]

i have just fitted new facias and sofits,the top of the facia is slightly higher
than the osb board.(no tiles or battens on yet)how do i keep the water running off the roof rather than it pooling on the felt?
or will this be solved when the tiles go on?

why? you have built a pond.

From the fact that you state tiles I assume that it is a pitched roof rather than a flat one. The tiles keep the water out not the felt so you shouldn't have a problem, the fascia needs to be higher than the sarking board (I see you're in Glasgow so of course scottish practice observed) to support the bottom of the tiles / slates
