Access to sloping roof with a flat top

[p.millson]

My house is at the corner of a forked junction and is therefore wider at one end than the other. It has a conventional tiled sloping roof, but at the top there is a leaded flat section, which is about one metre wide at one end and two metres at the other.

My question is: how can I (or anyone else) get access to the roof for repair when the hook on a roofing ladder is too narrow to fit over the apex of the roof? Is a scaffolding tower going to be necessary every time I need to replace a tile (which is quite often as the roof is old)? Does anyone have any suggestions? I don't suppose there is some sort of special roof ladder that will be safe to use with my roof?

Thanks

Peter

p.millson,
Sounds like you will need the scaffold tower every time.
If the tiles on your roof are that old a conventional roof ladder will probably break even more tiles where the support bars touch the roof.
