Membrane in a lead valley


Co1

Recommended Posts

Morning everyone. I could do with a bit of guidance on how to lay the roofing membrane into a lead valley. I’ve searched the internet and can’t seem to find anything that is clear. Any help would be appreciated. 
Thanks

You need A1f building paper This will stop the lead from sweating 

At £70 a roll many roofers will just Chuck a length of membrane in there 

But if you are going to do that you may as well use the cheap plastic valleys that all the mass produced houses are now using

Thanks a lot. So that goes between the roofing membrane and the lead?

don,t forget to fit the lead valley in lengths --NOT one piece

about 1.5m each bit and overlap  them

this will stop any problems from expansion of the lead  when roof is hot

also easier to get a long valley looking good
