How much MATERIAL to add for pitch increase

as in does your roof area increase as the pitch increases?

Yes it does

oohhh…now i get the question. Get a ladder and measure the plain of each roof. from ridge to drip edge…from rake to rake, multiply. that is your square footage.

why are there 3 different threads asking the same question?

width x length x pitch factor add 5%

thank you Z

gweedo.
