Roof pitch designations are comprised of two numbers indicating a ratio.
Roof 18 percent pitch.
Roof pitch refers to the slope which the rafter creates.
A pitch over 9 12 is considered a steep slope roof between 2 12 and 4 12 is considered a low slope roof and less than 2 12 is considered a flat roof.
Calculate the rafter length substituting these values into the following formula.
Roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run.
It s just a little math.
For budget conscious homeowners metal shingles will run about 7 to 10 per square foot.
Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs.
The following table shows how the same common roof slopes can be expressed using rise in run ratios degrees and percentages.
How roof pitch manifests itself in various roof types.
Roofing terminology for roof pitch are.
The table below shows common roof pitches and the equivalent grade degrees and radians for each.
What is a roof pitch examples.
You can assess this in two ways either as the roof pitch angles which the rafters make with the horizontal or the proportion between the run and the rise of the roof.
On blue prints architects engineers usually display the pitch of a roof in the format shown on the image where number 4 represents a rise and number 12 represents a length.
Calculate the roof pitch as the proportion of rise and run.
Roof pitch defined and explained.
This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.
The ratio can be indicated by a division slash separating the numbers such as 2 12 or 7 12.

Pitch is the term used to describe the angle slope or slant of your roof.
4 12 roof pitch 18 angle 18 43 degrees details.
To determine your roof pitch calculator.
Most roof s have a pitch in the 4 12 to 9 12 range.
No you cannot install metal shingles on a low slope roof.
To see roof pitch to degrees equivalents.
See the image below for more explanation on rise run and pitch.
Pitch rise run 1 5 6 25.
5 pitch 22 5 degrees 4 pitch 18 5 degrees 3 pitch 14 degrees 2 pitch 9 5 degrees 1 pitch 4 5 degrees 0 pitch 0 degrees.
A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally.

See below after the table for directions on how to convert any roof slope from one form to another even roof slopes not shown in the table.
A 12 in 12 pitch is a steep 45 degree angle roof.
Or the colon can replace the slash as in 2 12 or 7 12.
Measure the rise of your roof.
Let s say it is equal to 1 5 m.
Often you express roof pitch as the ratio between the rise and the run in the form of x 12.
