Age 5Explain it to a 5-year-oldStart with a picture
Imagine measuring a building job before shopping so you can estimate how much material the job needs. Estimate sloped roof area, roofing squares and shingle bundles from plan dimensions and pitch.
Age 15Explain it to a 15-year-oldConnect it to the formula
Estimate sloped roof area, roofing squares and shingle bundles from plan dimensions and pitch. A pitch factor converts horizontal plan area to sloped roof area. Waste is added before dividing by 100 square feet per roofing square and the chosen bundles per square. Change one input or choice at a time and compare the result to see which part of the rule it controls.
