Why wern't you keen cumbrianroofer? I've specified them plenty, assumed they were cheaper. Never had complaibnts from roofers or clients.....

yet! :p
 
i dont mind fibreglass valleys but these dry ones leave no gap so there seems t me there could be a build up of leaves and such under the tiles so then you could get a build up of water under the tiles of course does away with cement which is always a good thing this time of year anlead is more expensive but surely you get whatyou pay for
 
ive used a few but always cemented the valley but ive also been on jobs where the valley hasnt been cemented up with a lead valley.

yes ive done the standard fibreglass valleys and always cement them but these have a upstand down the centre of the valley and you cut to the upstand no cement to be used but they do look a bit ugly just wondered if any one had had any bad experiences with blockage cos dont want to go back to 90 houses cos valley gutters are blocked after 12 months
