Edit: having just re-read your last post, to sum up, trying to sort this by drilling holes in bits of wood for drainage is a right bodge and you'll end up with the same problems you have now. Fix the UPVC gutter behind the fascia, dress the membrane into it and drain it with a downpipe through...

I have put photos on an album on my profile. Is that the way to do it?[/img]

A bitumen sealant covers 12 inch of the roof down to the holes under the membrane. You can see the damp that has occurred with water coming back on itself instead of exiting through the holes.
