I want to leave a ladder on my rear extension roof semi-permanently, to give me access to the roof from an upstairs balcony.
I've looked at roof ladders, but they only seem to have hooks suitable for attaching to roof ridges. Unfortunately at the top of the roof where I want to lay a ladder is a small party wall, perhaps a foot or more in height.
Is there any other sort of ladder attachment I could use that would safely secure itself to the wall while still distributing its weight evenly over the roof?
Thanks,
Chris
