To calculate the roofing material requirements, you need to know the total roof area. The formula for calculating the roof area is:
Length = Roof length in feet
Width = Roof width in feet
Once you have the roof area, you can determine the number of shingles or tiles required. Typically, one square (100 square feet) of roofing material covers a certain amount of area, depending on the type of material.
