Roof Pitch Values

Roof pitches are read as a fraction or ratio, usually using the number 12 as the denominator. The numerator is the vertical height of the roof, and the denominator is the horizontal length (i.e. 4/12 = for every 12 horizontal feet, the roof drops (or rises) 4 feet).

Here are some recommended roofing materials for some of the more common roof pitches in Indiana:

1:12 to 3:12

These pitch values are in the lower range. Conventional shingles are not recommended for low pitched roofing systems because of the risk of moisture accumulation, which can lead to a long list of roof damages, including mold, mildew, algae, and moss growth. Low-pitched roofs have reduced water draining capabilities, which prevents shingles from being able to dry out thoroughly. Instead, you would need a water-tight seal, which can be achieved with a built-up and “torch-down” roofing, or standing seam metal roofs.
