[BlindHandyMan] Replacing a roof

[David Sexton]

Lucky me! I get to replace a shingle roof this summer. I have basic idea 
of how to go about this, but if y'all can send me some articles, tips, 
and what tools would make the job easier I'd be ever so grateful.
This is the standard tar shingles  not sure what they're called.
I need to take off what's there, and put new shingles on, don't know if 
I need to replace tar paper, wood or anything like that.
Maybe there is something better than shingles that is about the same price?
