pitch is the rise (or fall) in the run. A good draining roof in the south is one foot of fall per twelve feet of run. (for water drain) Northern areas need much more as they have ice and snow accumulations. As steep as possible is a good rule, but not so steep you can't stand on it to shingle it.

Take a steel square (big model),place the longer end flat
on the roof with the other end sticking up. On the bottom section mark the one foot spot. Then on the end sticking up mark either 2,4,6,8. This will give you a pitch of
2on twelve,4 on twelve and so forth.

an 5/12 pitch for example would mean that for every foot you come in from the rafter will rise 5 inches. so if it was 6 feet from the outside of your house to the face of the beam your rafters sit on the it will be 30 inches up from the top of your exterior wall since the top of your beam should be level with the top of your wall.(6x5=30)

they make special square's & anglefinders for this. apparrently you'll need a class on how to use them. go to home-depot, the classes are free. then depending on where you are; you'll set the correct pitch, ie; N.Y. mountains need 45 degree of pitch. good luck!

if you have to ask a question like that, sounds to me that you don't know how to build a roof... i'd suggest hiring someone that does.
