To find the sq. ft of a roof you have to measure the length and the width and multiply those figures together. Then you divide that figure by 100 and it will tell you how many squares of shingles it will take to cover it.

Your house is 1350 square feet how many shingles do you need?

The square footage of your house is not the same as the square footage of your roof if there is any pitch. If you are asking aboutasphalt shingles, generally each bundle covers 33.3 square feet. Therefore find the square footage of your roof, divide it by 33.3 to find the number of bundles, then multiply the original square footage by 5-10% to get the number of additional bundles for cutoffs and starter strip. The variation in percentage accounts for the number and length of valleys of the roof. Example:[@5%]roof =1500 ft2 --> (1500/33.3=45.05) (1500x.05=75 -->75/33.3=2.25)45.05 + 2.25= (48) bundles
