How The Calculation Works
Formulas, material coverage assumptions, waste buffers, and rounding standards.
Exterior siding is quantified in standard construction "Squares" (1 square = 100 square feet).
Calculates deductions for exterior doors (21 sq ft) and windows (15 sq ft).
Provides accessory requirements including starter strip linear feet and J-channel trim.
