How Your Roof Shape Affects the Material You Choose

Just like the climate you live in can affect the type of roofing material you use, so can the actual shape of your roof. Not every material can be fitted to accommodate certain angles and slope of your roof while still looking uniform and being functional. It’s important to determine your pitch in order to then pick your material.

Determining Your Pitch

Take the vertical height of your roof (the numerator) and place that number on top of the horizontal length of the roof (the denominator) to make a fraction — for example, 4/12 — and there you go, you have your pitch. (It’s important to note that the denominator is always 12.)

Different Pitches and Materials

.25/12 to 3/12 Pitches

These roofs have a lower angle and are typically seen on urban buildings or more modern homes. Several roofing materials are best for these pitches such as rubber membrane or standing seam metal.

4/12 to 20/12 Pitches

This is a common pitch for many residential homes and most often uses asphalt shingles. 4/12 to 20/12 roof pitches are a kind of middle ground for roofs since they are not too low or high-angled.

5/12 to 12/12 Pitches

These are higher-angled pitches that most often use wood or slate shingles. However, it’s important to note that some wood roofing materials don’t lock as well as other alternatives.
