You can make big bucks on a highly pitched roof, but you can also make one small mistake and be on the ground with a tibula or femur sticking out your skin and wonder how you will work now.
In my area, they charge plenty extra for high pitched roofs and they have the needed equipment and the expertise. Local roofers won't touch it.
I would really think this over thoroughly.
But, in answer to your question, you can rent those roof jacks, and you can get safety harness's and other gear, but you still have to know what your doing.
