Co1 Posted September 8 Share Posted September 8 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 Col Link to comment Share on other sites More sharing options...
nod Posted September 8 Share Posted September 8 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 1 Link to comment Share on other sites More sharing options...

So that goes between the roofing membrane and the lead? Link to comment Share on other sites More sharing options...

scottishjohn Posted September 8 Share Posted September 8 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 1 Link to comment Share on other sites More sharing options...
