FAQs
1. What does a 4/12 pitch mean?
A 4/12 pitch refers to the slope of the roof, where for every 12 inches (or one foot) of horizontal run, the roof rises 4 inches. This is a common pitch for residential roofs.
2. Can the calculator be used for different roof pitches?
Yes, the formula can be adapted for different roof pitches by adjusting the value of θ. Whether it’s a steeper or shallower pitch, the calculator can provide accurate measurements accordingly.
3. How do I measure the span of the roof?
To measure the span of the roof, simply measure the distance horizontally from one end of the roof to the other. This will give you the total span, which is used in the calculation formula
