If it's tiled then its very easy to get to by sliding/pushing back a few roof tiles. Colorbond will require unscrewing the sheet. Are your eaves 450mm or 600mm? If 600mm I'd advise to put the noggin to avoid sag in the sheet. It is tiles. Eaves are 450mm. Because we are on a slope this corner of the house is pretty high and will require about 4m long ladder, which I don't have. So, I'll go with toggle bolts.
