Steep pitch vs. low pitch styles As an example, 8/12 means that for every foot, the rooftop rises 8 inches. Slopes around 6/12 are the most common, while anything below 4/12 is typically considered a low pitch.
Is 8/12 a common roof pitch?
Most roofs have a pitch in the 4:12 to 9:12 range. A pitch over 9:12 is considered a steep-slope roof, between 2:12 and 4:12 is a low-slope roof, and less than 2:12 is a flat roof.
What is the most common roof pitch?
Conventional slope roofs are most common with residential roofs. This means the slope has a pitch between 4/12 and 9/12 on most homes. Roofs with a pitch exceeding 9/12 are called steep slope roofs.
What does 4/12 mean for the pitch of the roof?
Roof slopes are most commonly defined by the rise-over-run ratio. If a roof slope “rises”, say, 4 inches when measured 12 inches along the bottom of a horizontal roof truss, the roof slope is said to be 4:12; i.e., 4 inches of rise per 12 inches (one foot) of run.
What is a 8x12 pitch roof?
The 8/12 or 8 on 12 roof pitch are most common types of residential roof pitch which are a sloping surfaces with an angle of usually 33.69° degrees steepness of a roof with it's vertical rise of 8 inches over its 12″ or 1 foot horizontal distance or run in building construction.
What is the easiest roof pitch to build?
Gable Style Shed Roof A gable style is the easiest to build, but offers very little storage in the attic. Unless of course you have a very steep pitch on your trusses or rafters. Then you will have more storage. The steeper the pitch though, the harder it is to put shingles on!
What is the best roof pitch for a shed?
I always recommend at least a minimum pitch of 1 in 40. This translates into a fall of just under 2.5" on an 8 foot roof. Fix your roof deck and you are done!
How do I convert roof pitch to degrees?
- To convert a roof slope expressed as “X-in-12″ to a roof slope expressed in degrees, find the arctangent of (rise/run).
- Divide the rise (that's the “X”, yours will vary) by the run (always 12).
- Using a scientific calculator, find the arctangent of the result.
How do you calculate pitch degree?
For a pitch expressed in inches per foot, convert to a fraction first, e.g. a 4 in 12 pitch becomes 4/12, then divide. Next, find the degrees by finding the slope's inverse tangent, e.g. degrees = arctan(slope).
What is a 22.5 degree pitch?
A 6 in 12 slope = 26.5651 degrees, and 4.97056 in 12 slope = 22.5 degrees.
What degree is a 4x12 pitch?
approximately 18.4 degrees

How do you convert angle to pitch?
If you know the roof's angle in degrees, you can find the roof pitch by converting the angle in degrees to a slope, then finding the rise by multiplying the slope by 12. First, find the slope by finding the tangent of the degrees, e.g. slope = tan(degrees). Then multiply the slope by 12 to get the rise.
What is a 3/12 pitch in degrees?
This means that the roof rises 4 inches for every 12 inches it runs. ... So, the 4/12 roof pitch angle is about 18.4°. A 3/12 roof pitch angle is about 14°, so on and so forth.
