Fascia forting to garage

[round01]

I'm thinking of capping over the timber fascia on my garage to make it look a bit neater but have a few questions...

The felt roof over hangs onto the fascia and looks pretty tight to the timber. Is their a way of fitting the fascia up and under the felt or is their another way of doing it?

Thanks for your help

Just noticed the title should be fitting not forting.....
