As old as your roof is, it might not have any "Ice & Water Shield", which is a peel and stick underlayment. Designed to be used continuous on roofs below 3/12 pitch as an underlayment, and along all roof edges, eaves, valleys and the like (24" horizontal from the inside of the wall is code here in Michigan).
This underlayment is also granulated and I've seen some people try to use it as an exposed roofing, but do not recommend this as I have not tried to get away with this myself.
A true "flat roof" roofing would be better with such a low pitch, follow the directions and recommendations of what ever you select. Shingles on such low pitches tend to curl up, much the same way they do on totally vertical surfaces.
My first thought when I saw your roof was to go metal, but metal is not something you want to do yourself.
Above all:
Follow the manufactures instructions and directions.
