If the slope is 9 inches per foot (run), then the roof is 15" per foot run.
I suppose rake factor is the ratio of roof length to rise, which works out to 1.25 in this case.
The roof area (for one sloping face) is therefore
(15"/9")*10'*30' long
= 500 sq. ft.
If the roof has another sloping face, then double the above.
