How to Measure a Quonset Roof

Mathematical Method

• 1

  Measure the horizontal width of the Quonset roof to determine the diameter. Measure from the base at each side across either end.

• 2

  Multiply the diameter dimension time 3.14, referred to as "pi," and then divide the result by 2 to determine the circumference measurement of the Quonset roof.

• 3

  Measure the overall horizontal length of the Quonset roof and multiply this dimension times the circumference determined in Step 2 to define the area of the Quonset roof in square feet.

Direct-Measure Method

• 4

  Extend a cloth or flexible metal tape over the outside diameter of the Quonset roof and measure the dimension between the base of the curve on each side. This measurement will define Quonset roof's circumference dimension.

• 5

  Measure the overall horizontal length of the Quonset roof.

• 6

  Multiply the dimension determined in Step 1 times the length dimension defined in Step 2 to calculate the area of the Quonset roof in square feet.
