2 10 Roof Pitch

Pitch is the term used to describe the angle slope or slant of your roof.

2 10 roof pitch.

An example for a steep sloped roof is 8 12. 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. The combination of two numbers are used to display or show the roof pitch. A roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 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. The first is from the top of the roof. Enter run the flat level length then click pitch angle or rise to select then enter other known dimension angle or pitch. Roof pitch designations are comprised of two numbers indicating a ratio.

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. The slope of a roof or pitch is determined by how many inches the roof rises over 1 foot or 12 inches. Two most common methods 4 12 or 4 12 are used for marking the pitch of a roof. Resilient asphalt shingles lie much flatter to the substrate than slate tile and concrete which keeps water from being easily blown under them.

There are two suggested ways to measure a roof pitch. Simply mark a. Roof pitch refers to the slope which the rafter creates. To put it in perspective the angle of this slope would be around 30 degrees.

The ratio can be indicated by a division slash separating the numbers such as 2 12 or 7 12. This means that the rise of the slope goes up or down 8 inches for every 12 inches.

Or the colon can replace the slash as in 2 12 or 7 12. Roof pitch defined and explained. Pitch is thus the ratio of the rise in inches to a 12 inch run and is often expressed using a semicolon for example 6 12. A pitch of 2 12 is the minimum pitch for shingles made of asphalt so your roof just barely makes the cut off for one of the most popular roofing material options.

This means for every 12 horizontal units the roof must rise a minimum of 2 vertical units. Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot. Sometimes pitch is also expressed in. Asphalt shingles can only be installed on roof slopes of 2 12 or greater.

Asphalt shingles minimum roof slope roof pitch r905 2 2. Often you express roof pitch as the ratio between the rise and the run in the form of x 12.
