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

Just joined the site. I’m Col, electrical engineer by trade but been around the building game my whole life. About to embark on a couple of self build extension where I will be doing it all single handed, so hoping to get loads of advice on here. Thanks.
