The vertical measurement reflects how steep the roof is and contributes to the general pitch ratio. It’s essential to ensure 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 process may embody simple mathematical operations. For example, if the vertical rise is 5 toes and the horizontal run is 12 ft, the pitch ratio would correspond to 5:12. This fraction provides clear insight into the roof's design.
