How tall is the peak of a house?

Common Peaks Are 60 to 84 Inches The most common pitches for houses are 5/12 and 6/12 and the most common runs are 12 or14 feet, for roofs 24 or 28 feet wide. A 12-foot run has a peak of 60 inches with a 5 pitch, 72 inches with a 6. A 14-foot run would have comparable peaks of 70 and 84 inches.

How do you determine the slope of a roof?

If you know the roof’s angle in degrees, you can find the roof pitch by converting the angle in degrees to a slope, then finding the rise by multiplying the slope by 12. First, find the slope by finding the tangent of the degrees, e.g. slope = tan(degrees). Then multiply the slope by 12 to get the rise.
