The vertical measurement displays how steep the roof is and contributes to the overall pitch ratio. It’s essential to ensure that these measures are as exact as possible, as even minor inaccuracies can have an result on the overall pitch and consequently, the roof's efficiency.
Once each the rise and run measurements are established, the pitch can be calculated by forming a ratio. This course of may embody simple mathematical operations. For example, if the vertical rise is 5 toes and the horizontal run is 12 feet, the pitch ratio would correspond to five:12. This fraction offers clear insight into the roof's design.
