When applied properly 3 bundles will cover 100 square feet.
25 x 14 = 350 sq ft.
350 /100 x 3 = 10.5 bundles. So you need 11 bundles, assuming little to no waste.
You need to estimate the size of the roof in square feet.A bundle of shingles will cover 33 square feet, so divide the square footage of the roof by 30and that's how many bundles of shingles you'll need.The extra 10% will end up getting used as starters and the cap.Shingling a roof isn't difficult, complete directions are printed on every bundle.But if you've never shingled a roof before you might want to pick up a couple of extra bundles.You can always return them after.
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
You just have to measure it. Height times width and double that for simple roofs. Lots of angles or dormers will have to be allowed for. 3 bundles in a square. 1 square covers 100 square feet. Height times width gives you the square footage and do the math. Assuming you are talking about asphalt shingles they can be up to 5 bundles per square if you are using dimensional shingles. the standard flat three tab shingles are 3 bundles per square. You can calculate roof area just based on the dimensions taken on the flat. There are different multipliers to use that depend on the pitch of your roof.
384 square feet - without using a calculator !
If the dimensions are in feet then 16 times 16 = 256 square feet

at least 25 bundles With an average of 3 bundles per square(100 square feet) an 8 square roof would need 24 bundles plus 1 for cuts and shorts.
4 bundles for 15 year. 3 bundles for 25 year.
How much area would 15 bundles of shingles cover. Standard duty shingles use 3 bundles for every 100 square feet so 15 bundles would cover 500 square feet.
4 bundles
26 bundles should be about right.
8 bundles
Roughly 24 SQ. Which is 2400 Square feet. Depending on waste, valley's etc. There is 3 bundles to a square. So the answer is 72
73 bundles

100 square feet is called a 'square'. Given that, you roof is 36 'squares'. Shingle coverage for 20, 25, and 30 year shingles is 3 bundles per square. 40 and 50 year shingles are 4 bundles per square. Say the shingle you select has a coverage of 3 bundles per sqaure: the number of bundles you need would be 3 * 36, plus the amount for caps (which cover the 'peaks' and 'hips' in your roof. To estimate the amount of bundles you need for peaks, assume one bundle for every 25 feet of 'hip' or 'peak' you need to cover.
