GRP Valley Question

[Rolyberkin]

Hi

Has anyone got a picture or diagram of how a grp valley falling into an internal 90 degree gutter corner should look when completed correctly.

I am getting a leak into my soffit which I am told may be that the valley does not extend far enough into the gutter.

Also should the valley be cut square at the end which extends into the gutter.

Thanks in advance for any advice.

on alot of the valleys we do with grp we keep the grp valley up the roof about a foot and fit a piece of lead under grp valley and into gutter

Thanks for your reply, this is what I had actually done but there seems to be a leak into the soffit, I noticed today after a particularly heavy downpour that the water was shooting down the valley and jumping over the gutter, not sure whether this was just sheer volume of water, think I will have to strip it back and see if there is an obvious issue?!
