Fórmula

## How to Calculate Roof Area ### Formula **Roof Area = Footprint Area × Pitch Factor** **Pitch Factor = sqrt(1 + (Rise/12)²)** | Pitch | Factor | |-------|--------| | 4/12 | 1.0541 | | 5/12 | 1.0833 | | 6/12 | 1.1180 | | 8/12 | 1.2019 | | 10/12 | 1.3017 | | 12/12 | 1.4142 | This method converts the horizontal footprint into the actual surface area by accounting for the roof slope.

Ejemplo Resuelto

A building 50 ft by 30 ft with a 6/12 roof pitch.

  1. 01Footprint area = 50 × 30 = 1,500 sq ft
  2. 02Pitch factor = sqrt(1 + (6/12)²) = sqrt(1.25) = 1.1180
  3. 03Roof area = 1,500 × 1.1180 = 1,677 sq ft
  4. 04Roofing squares = 1,677 / 100 = 16.8 squares
