100 square foot of coverage

So, if my roof measures 24 x 36 x 2 1,730 square feet equally 17.3 squares?

At least.

Pitch of roof factors in (stepper the more expensive), as well as how
many linear starting feet are needed (if you have a simple peaked roof
it's cheaper than a colonial with a separate peak for each upstairs
window, etc.

Best way is to get a few pros out to give you a free estimate.
