Hello all, I am currently having an extension built and we have come to a bit of a stop with the roof. I won't bore you with the whole story but basically my builders have made a poor job of the valleys where the new roof meets the old roof (at a right angle) the pitch on the existing roof and on the extension is 22.5 degrees and the tiles are a square section large interlocking (designed for the pitch).
The open GRP valleys have been finished very poorly with uneven cuts and very thick uneven mortar beds. The guys have tried to tidy it up a couple of times but it just seems to be getting worse so I have decided to get a local roofing company to re do the valleys and parts of the new and existing roof.
They have recommended the use of a GRP Central up-stand rib trough type 'dry' valley where the cut edge of the tiles sit against the central rib. They also want to strip back the new roof to re gauge the tiles.
The only thing that worries me is that I have a large willow tree close the the house and i'm concerned that these closed type valleys will get blocked up with leafs and tree debris which will compromise the weathering of the roof which is already quite a low pitch. Should I be concerned?
Any advice would be appreciated.
