Roof 18 percent pitch.

See the image below for more explanation on rise run and pitch. 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. 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.

Roof pitch designations are comprised of two numbers indicating a ratio. Or the colon can replace the slash as in 2 12 or 7 12. Most roof s have a pitch in the 4 12 to 9 12 range. Pitch is the term used to describe the angle slope or slant of your 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. To see roof pitch to degrees equivalents. Also see our page quick reference. Degrees to roof pitch rise in run to see a table.

Roof slope roof angle and pitch degrees. What is a roof pitch examples. A 12 in 12 pitch is a steep 45 degree angle roof. 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.

Calculate the rafter length substituting these values into the following formula. The ratio can be indicated by a division slash separating the numbers such as 2 12 or 7 12. 4 12 roof pitch 18 angle 18 43 degrees details. For budget conscious homeowners metal shingles will run about 7 to 10 per square foot.

Calculate the roof pitch as the proportion of rise and run. Measure the rise of your roof. Let s say it is equal to 1 5 m. 5 12 roof pitch 22 angle 22 62.

Roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run. A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally. This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees. To determine your roof pitch calculator.

Often you express roof pitch as the ratio between the rise and the run in the form of x 12. Roofing terminology for roof pitch are. Roof pitch refers to the slope which the rafter creates. 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.

The examples below provide visual examples of roof pitch. No you cannot install metal shingles on a low slope roof. To see how pitch impacts the look of a garage and changes cost click the design center button on our pole barn kits page. Roof pitch defined and explained.

The table below shows common roof pitches and the equivalent grade degrees and radians for each. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs.
