So, I have a downpipe that has come adrift above my kitchen extension that is now causing water to leak into the kitchen below. I need to be able to get onto the extension roof to reaffix the downpipe as shown in the attached pictures. I have a normal set of ladders but obviously they wont help here as I need to actually walk on the extension roof so I am wondering whether I need some special ladders to be able to access? Something like conservatory ladders would do the job maybe? Is there something I could buy or hire that I could attach to my existing ladders that would allow me to walk up onto the roof to repair the downpipe? Any suggestions greatly appreciated?
