Measure the area to be covered carefully and take into consideration the clope of the roof.
Roofing materials are measured by the "square" instead of using "square feet" and the number of bundles will depend on the type of shingle that you are planning to use.
A "square" equals one hundred square feet, so you are looking at four squares of shingles (including sixteen square feet of waste which is about right).
Standard asphalt shingles of average weight require three bundles per square so if using this type of material you would obviously purchase twelve bundles.
However, if you are using the more attractive and longer-lasting dimensional shingle, this material require four bundles per square and your needs would be sixteen bundles. These shingles also require twice as many nails and the warranty from the manufacturer is void if you use fewer nails or staples.
Also consider using thirty pound felt instead of the usual fifteen pound felt commonly used to save money. In the long run the roof will last longer with the thicker felt and thirty pound felt is actually easier to install than its lighter cousin due to the fifteen pound felt's tendency to tear during installation.

Roofing shingles are measured in "squares". One square is 100 square feet. *ASSUMING YOUR ROOF IS FLAT OR NEARLY FLAT* 16' x 80' = 1280 square feet. You'll need 12.8 (or 13) squares of roofing shingles. The majority of roofing shingle bundles are 3 bundles per square. 13 squares times 3 bundles per square = 39 bundles (minimum). Good luck!
A 30x50 roof has 1,500 square feet which is 15 squares. 3 bundles of shingles equals 1 square so you will need about 45 bundles.
