You measure the roof to get the square feet. There are 100 square feet in a square. On a straight single peak roof it's height times length on one side and double it. Then divide the total square feet by 100. This final number will give you the number of squares you have.
If the roof is a flat, commercial roof, it is the same (100 sq. ft = 1 SQ). However, if it is a metal panel commercial roof, you need to add in "stretch factor" or the added amount of square footage if the panels were to be stretched flat. A good estimate for this is: If the ribs on the metal panel are 1" tall, add 10% to your square footage; if the ribs are 1.5" tall, add 15% to your total square footage. So, if you have a metal roof that is an R-panel (_/-\_), the ribs are 1.5" tall and the roof is 100 SQ (or 10,000 sq ft), take 10,000 sq ft + 15% (1500) = 11,500 sq ft (115 Squares).
