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 exact as possible, as even minor inaccuracies can have an effect on the general pitch and consequently, the roof's performance.
Once both the rise and run measurements are established, the pitch could be calculated by forming a ratio. This course of might include simple mathematical operations. For example, if the vertical rise is 5 feet and the horizontal run is 12 feet, the pitch ratio would correspond to 5:12. This fraction provides clear insight into the roof's design.
