Hi.
I am about to have the roof coverings fitted and would like to get some info on the different valley details.
I have recently seen a new build where the tiles have been cut very close together and you cannot see the valley at all. I have been told that this is a dry valley trough. I would personally like to have this as it looks the neatest way of forming the valley.
A roofer that I had to give me a quote said that I do not need one of these. He said that I can either use lead or a GRP trough and he will cut them tight together.
However, after speaking with a manufacturer they have told me that a normal GRP trough/Lead needs to have the sides cemented, so they can't be cut close together.
After telling the roofer this, he said that, that is what they advise, but he doesn't advise it. When the mortar finally breaks down it lodges in the valley and creates leaks, so he never cements the sides. He said he has been roofing for over 30 years and has never had a problem doing it the way he does.
Is he advising me correctly or should I just by the dry valley trough and make sure it's done the right way.
Cheers.
