Steepness of roofs climate.

Pitch is a measure of the steepness of a roof. A reputable roofing contractor will be familiar with the pitch required by these codes. Steep slope roofing is defined as any roof pitched greater than 3 in 12 or 14 degrees or 25. For example a 6 12 roof pitch means that the roof rises 6 for every 12 moving inward.

The pitch of a roof refers to its steepness and states how many inches the slope rises for every 12 inches it runs horizontally. Pitch of your roof.

It s the measure of the steepness of a roof or its slope. For example extra precautions such as using a hoist may become necessary.
