Roof Pitch Vs Angle

For most home styles roof pitches fall in a range 4 12 a moderate slope up to 8 12 fairly steep.

Roof pitch vs angle.

Roofs having a lower pitch have a greater chance of creating water leaks as well as ice damming and so they require an intensive waterproofing system. Pitch rise run 1 5 6 25. Put again this value into an angle. Examples of extreme slopes range from 1 4 12 almost flat to 12 12 sloping down at a perfect 45 degree angle.

Lastly you can have the roof pitch in the form of x 12. Angle arctan pitch arctan 0 25 14. Compute the roof pitch as the percentage of rise and run. Now it is 3 12 and can be written as 25 or 14.

The tilt angle in degrees is used when determining the performance of a solar system. High and low pitch examples two examples at each end of the spectrum. X pitch 12 0 25 12 3. Roof pitch and roof angle degrees the tilt angle of the solar array is taken into consideration when the system is being designed.

Two most common methods 4 12 or 4 12 are used for marking the pitch of a roof. The combination of two numbers are used to display or show the roof pitch. Roof pitch angle and slope factor charts. In the roofing trade the go to term is pitch and it is expressed in terms of 12 inches so the pitch of a roof is determined by how many inches the slope rises for every 12 inches it runs horizontally.

If the solar system is being ground mounted or tilted up on a flat roof top the tilt angle is also used to determine the row spacing of the array so the front row of modules will not shade the row of modules behind it. Roof pitch is a term describing how steep or flat your roof slope is.
