Roof Pitch Options

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.

Roof pitch options.

Roofs on victorian era houses were often sharply angled with a steep pitch. Pitches lower than 4 12 have a slight angle and they are defined as low slope roofs. 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. Anything under 3 12 is a low pitch roof.

Anything above 6 12 is a steep roof pitch since it becomes harder to walk on the roof. 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. A 3 12 roof pitch angle is about 14 so on and so forth. Pitches of less than 2 12 are considered flat roofs even though they may be very slightly angled.

Think of a classic addams family haunted house with its soaring peaks and you have a picture of a high pitched roof. Visually this roof appears flat. Pitches above 9 12 are very highly angled and are designated steep slope roofs. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.

This is one of the rare pitches where the numerator is greater than the denominator with a slope as high as 18 12. There are some standing seam metal roofing options available from atas and other manufacturers that can be installed on a roof with pitch of 1 12. First of all they require less material and therefore cost less. This pitch might be as low as 1 12.
