The vertical measurement reflects how steep the roof is and contributes to the general pitch ratio. It’s essential to make certain that these measures are as precise as attainable, as even minor inaccuracies can affect the general pitch and consequently, the roof's efficiency.
Once both the rise and run measurements are established, the pitch could be calculated by forming a ratio. This course of may embody simple mathematical operations. For instance, if the vertical rise is 5 feet and the horizontal run is 12 ft, the pitch ratio would correspond to five:12. This fraction offers clear insight into the roof's design.
