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 pitch might be as low as 1 12. Pitches of less than 2 12 are considered flat roofs even though they may be very slightly angled. Pitches lower than 4 12 have a slight angle and they are defined as low slope roofs. Anything under 3 12 is a low pitch roof.

Pitches above 9 12 are very highly angled and are designated steep slope roofs. This is one of the rare pitches where the numerator is greater than the denominator with a slope as high as 18 12. 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. First of all they require less material and therefore cost less.

Low pitched roofs also have some definite advantages in certain situations. The most commonly used roof pitches fall in a range between 4 12 and 9 12. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. 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.

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. 4 12 is quite typical. Visually this roof appears flat. 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.
