It always takes a little more than you think because extra shingles go on the cap, first corner, and front edge of the roof. I just did the front half of my small house, and I learned by watching videos on Bob Vila's website. He has lots of videos and articles so it will take quite a while to find the best videos. I did an area about 168 sq. feet, and it took 7 bundles. You can always return any unused bundles to the homecenter. The bundle will say how much area it covers - i.e. 32 sq. feet or whatever. I found that I needed a little more than the estimate.
fourteen. 1 ft. = 12 in. 168/12 = 14 in.
14 ft.
14 ft X 12 ft = 168 Sq. Ft /9 = 18.67 (19)
A square covers 100 sq. ft. so 7 squares plus 2 bundles for the starter course and the ridge cap.
14 ft = 168 inches
100
168 in.
5.85 squares + 15% waste = ~6.75 squares of material needed 1/3 square per bundle of shingles 20 - 21 bundles of shingles (buy 21 and return the extra if necessary - it's i'mportant to have shingles from the same pallet/factory for matching purposes.
Do you mean inches well in ft it`s 14 ft. In inches it`s 168 inches.
136' x 168' = 22,848 square feet
168 square feet.
general rule is 3 bundles of shingles cover an area 10 ft by 10 ft (known as a square).
