Next, the vertical rise should be determined. This rise is measured from the very best point of the roof down vertically to satisfy the horizontal run measurement. The vertical measurement displays how steep the roof is and contributes to the general pitch ratio. It’s crucial to ensure that these measures are as precise as attainable, as even minor inaccuracies can affect the general pitch and consequently, the roof's performance.
Once both the rise and run measurements are established, the pitch can be calculated by forming a ratio. This process may embody easy mathematical operations. For instance, if the vertical rise is 5 ft and the horizontal run is 12 ft, the pitch ratio would correspond to 5:12. This fraction offers clear insight into the roof's design.
