One hundred square feet of roof area, which is the unit roofing material and labour are counted in. A twenty-four square roof is 2,400 square feet — measured on the slope, not on the footprint of the house, so a steep roof holds far more squares than its plan area suggests.
In FieldQuo — Measure from the sky
FieldQuo returns roof area and pitch from the address, so the squares are counted before anybody gets on a ladder.
