Thanks for the response as you can see, the trim edge is close to the Fascia. it is about a 10m gutter run, so at one end the trim is below gutter rim and it’s above at the other end. The problem is in the middle where they are at same height and capillary action is pulling water around the trim edge and onto the gutter edge and then fascia thanks

I had a felt flat roof replaced a few years ago by GRP. I have noticed that water is curling up behind the edge trim and round the back of the guttering onto the fascia. Some of this is making its way over the top of the fascia and into the roof structure. I think the crux of the problem maybe that the gap between the inner lip of the edge trim and the fascia is only circa 10mm. This means the gutter edge in places is mm away from the edge trim. I have removed the gutter in case it is too high and impacting the water flow, but it makes no difference. How do I solve the problem? Packing out behind the edge trim would increase the gap, but from testing it with a hose, it is not the solution as I gain maybe 7 or 8mm. Fiddly, but the best idea I have come up with is using a self adhesive flashing like AluFlash and stick it to the inside of the edge trim over the batten under the roof lip and down a portion of the fascia before trailing it in the gutter. Apart from having the edge of the roof refitted, is this my best solution or can anyone think of anything else I could do? Thanks Steve
