There are several factors to consider when building a roof for a new construction. To protect those inside the building from the elements, contractors must create the proper pitch for the building materials used. If you’re designing a roof, learn more about this concept to understand why it’s important.

What to Know About Roofing Pitch

What does it mean?

Pitch refers to the roof’s steepness, which measures the angle of the surface’s vertical rise in proportion to its length.

Structures can be either mostly flat or pitched. A ratio of 8:12 means the surface rises at a 33° angle. The higher the first number, which indicates rise, the steeper the surface is. 

Does pitch affect shingle choice?

Yes, the pitch impacts the material options you have for construction.

For example, a flatter surface can’t receive tile or metal, as these materials may sustain moisture damage from pooling water. More common on commercial builds, flat roofs require moisture-resistant materials, such as gravel. A steeper slant allows rainfall to filter into the gutters, preventing water damage.

What are the most common pitches?

Low-slope pitches usually have 1 to 4 inches of rise to every 12 inches of length. Medium-level versions, which are the most common, have 4 to 9 inches of rise per foot of run. 

Any rise higher than these levels qualifies as steep, which may require extra fasteners to secure. Roofs can also have single pitches or several throughout their structures.

What’s the advantage of a steeper pitch?

Higher pitches are more effective at draining rain and snow, preventing leaks and increasing their materials’ life spans. This also helps prevent clogging in roof-mounted drains and vents. 

Steeper roofing has a distinct, elegant quality, and can even make an attic roomier by creating a higher ceiling.
