I use a hook ladder if the roof is unwalkable, like the ones from the fire station to climb on the roof when needed, yep its a special ladder that hooks over the peak of the roof. I wrapped the hooks so they wouldn't damage the peak. I only use this if I have to. I did two metal roofs last wk and they turned out nice. I used a weak sh mix. I treated the roof and used a twenty foot extended pole with a soft brush. scrubbed the roof and hosed of with a garden hose. here are the pics. I don't like to do metal roofs at all but I charge a high price and I let the owners no if its to bad I may not be able to make it perfect but much better.

 Bob, you mentioned that you use a hook ladder and wrap the hooks so they won't damage the peak. I don't own ladder hooks but have seen them and wondered if they cause damage. Just out of curiosity, what did you use to wrap them?
