Our house has a long dormer, surfaced with some sort of weatherboard (I suspect synthetic).
There are joints in this, which look to be leaking when rain is driven from the south.
The roof pitch is a bit steep to walk on, and the roof is made of quite old eroded concrete tiles.
The dormer is about 1.5m back from the gutter and there is about a 3m drop to the ground.
I'm trying to work out how to get access to the dormer front.
Only half decent idea I have is to use a roofing ladder to go up the back of the house, another roofing ladder laid going past the dormer and then walk along the dormer flat roof. Not overkeen on this due to potential for damage to flat roof (but I suppose I could lay planks on it).
That's not a great solution though, because the dormer is taller than the length of my arms.
I did wonder about a 'conservatory access ladder', but these seem to be a bit short.
