Measure all sides of your roof. Width times Length.
Add up all the square footage you have.
Add 10% for waste
If you are using a 20, 25 or 30 year 3-tab, each bundle covers 33 1/3 square feet.
If you are using #1 or #2 cedar shingles, each bundle covers 25 square feet.
Divide the number of square feet you have by either 33.3 or 25 depending on the type of shingle you want.
A side note: Most roofing manufacturers have an upper end shingle. 40 and 50 year laminate composite shingles. These cover less square feet per bundle. Typically 25 square feet. These types of shingles are thicker and will last longer.

1. find out how many bundles are in a square of the brand of shingle you want. 2. length x the distance from the gutter to the peek on both front and back sides of the house. 3. add 2 bundles for under starter course and a bundle for every 25' of length for cap shingles. 4. a square is 100 square feet. 5. divide your total roof size by 100 that will be how many squares of shingles you will need.

depends how big the shingles are, and how big the roof is, measure the roofs lenght and width and multiply that, and u get the total square feet area, go to the store and see how much square feet a pack of shingles covers and divide that number by the total area of the roof, and get that many packs, ps. make sure u have the right measurements and units such as Feet or Centimeters u dont want to come out short or buy ten times more, so if u measure ur roof in feet convert the measurements into feet or u can get a contractor to do the whole thing

Measure length times width of your actual roof areas. One square is 100 square feet. Shingles come standard or metric. When you select your shingle at your home improvement store the package will tell you how many bundles will make a square. Standard is 3 bundles per square. Metric shingles are 4 bundles per square. Dont forget your starter row.

Wow Gary had a very nice answer.
Didn't think someone would add that 10% waste. However if your roof doesn't have any valleys or hips then you don't have to go that high. But you can always return any unopened bundle. SO more is better, it always sucks having to go back for another bundle.
Just measure it up from. Usually 3 bundles to a square. 10 square roof, 30 bundles.
ALso 3 sheets of plywood equals a square if that gives you a visual.

Length X Width = Area
Make sure you measure actual surface areas and not just the perimeter of your roof. When estimating, factor in cutting, slope, ridge lines, and extra for a dog house.
Three bundles of shingles make a "square". A square theoretically covers 100 square feet.
