Roof Pitch Options

Anything above 6 12 is a steep roof pitch since it becomes harder to walk on the roof.

Roof pitch options.

This is one of the rare pitches where the numerator is greater than the denominator with a slope as high as 18 12. Finally a higher pitched roof is more visible something you should consider when deciding between a painted or galvalume roof for more on color choices see the panel options section. The picture below shows the pitch of a 7 12 roof slope meaning that for 12 of horizontal measurement roof run the vertical measurement roof rise is 7. Low pitched roofs also have some definite advantages in certain situations.

Pitches lower than 4 12 have a slight angle and they are defined as low slope roofs. This pitch might be as low as 1 12. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. Think of a classic addams family haunted house with its soaring peaks and you have a picture of a high pitched roof.

The most commonly used roof pitches fall in a range between 4 12 and 9 12. Visually this roof appears flat. 4 12 is quite typical. Roofs on victorian era houses were often sharply angled with a steep pitch.

Anything under 3 12 is a low pitch roof. Pitches of less than 2 12 are considered flat roofs even though they may be very slightly angled. First of all they require less material and therefore cost less. So you would need to pick the right option as most regular standing seam metal roofs will require a roof pitch of 2 12 or even 3 12 at a minimum.
