13 square. 1 square of shingles is 100sq feet.
That depends on the size of the shingles. ************************************************************** Size of shingles makes no difference. Shingles are sold by the bundle and the amount of bundles per square depends on the weight of the shingles. So you could have 3 bundles, 4 bundles or 5 bundles per square but they still add up to a (100 sq ft) square. The only difference would be if you are dealing with metric shingles, which is not going to make a big difference in the area covered. A square of shingles covers 100 sq ft. So for a 672 sq ft roof you will need 7 squares. Dave
i think it should take 7 bundles
each bundle does 33.3 sq ft.
It says on the side of the box of shingles how many square foot it willl cover so figure that out and multiple tilll.you hit two hundred say each box did ten square foot you would nned twenty boxes,
A square covers 100 sq. ft. so 7 squares plus 2 bundles for the starter course and the ridge cap.
a square in roofing stands for 100 sq ft. so in this case you have 192 sq ft or 1.92 squares. you must also allow for the starter row, cap, and waste. i good rule is to add 10% to your measurements. 192 x 1.10 = 211.2 sq ft or 2.1 squares. this would be 7 bundles of most shingles ( 3 bundles/square)
With composition shingles of lighter weight, three bundles will do a square (one hundred square feet). Heavier shingles often come packaged as four bundles per square. Some of the shingles come in as much as 7 bundles per square like the GAF-Elk Camelot they are more expensive but look good and have a lifetime warranty.
There are 3 times 7 = 21

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.
