24 X 12 Roof Pitch

The table below shows common roof pitches and the equivalent grade degrees and radians for each.

24 x 12 roof pitch. 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. 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. With that as background you are now ready to estimate how many shingles you will purchase for your roof project. In the united states a run of 12 inches 1 foot is used and pitch is measured as the rise of the roof over 12 inches.

This roof shingle calculator requires four basic inputs. If you want to find the roof pitch in the form of x 12 simply calculate the pitch and substitute 12 for the run length. The value displayed as the rise will be your x. Slope the slope of a roof is represented as x 12 where x is the number of inches in rise for every 12 inches of run this is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares.

Measure the run length it is the horizontal distance between the roof ridge and the wall of the building. To find the amount of plywood needed to cover a roof start by finding the area of the roof. A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally. It is often compared to slope but is not exactly the same.

4 12 roof pitch 24 in. Built with spf or syp for added durability. Roof length measured in feet roof width measured in feet roof pitch. Complete your building project work easier by using this roof pitch center roof truss.

See the image below for more explanation on rise run and pitch. This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees. On center roof truss 269520 the home depot. Roof pitch degree table.

Most roof s have a pitch in the 4 12 to 9 12 range. Find the area of a roof. There are also 29 standard sized shingles measuring 12 inches by 36 inches in each one of these. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs.

Once the area is known divide by the area of a 4 8 sheet to find how much sheathing is needed. We included a roof pitch chart below the 7 12 example image and the calculator below that. A 12 in 12 pitch is a steep 45 degree angle roof. Angle the angle of a roof is the same as the roof s slope except instead of being.

Let s assume it is equal to 6 m. Image 1 12 to 12 12 roof pitch 7 12 pitch. Roof slope calculator example of use. Multiply the length of the roof in feet by the width of the roof in feet to find the area of the roof in square feet.
