2 10 Roof Pitch

The combination of two numbers are used to display or show the roof pitch.

2 10 roof pitch.

The triangle diagram will be re drawn to scale with all dimensions marked. 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. The first is from the top of the roof. Often you express roof pitch as the ratio between the rise and the run in the form of x 12.

Drag sliders to animate the results and diagram. Simply mark a. Roof pitch defined and explained. Roof pitch refers to the slope which the rafter creates.

Two most common methods 4 12 or 4 12 are used for marking the pitch of a roof. This means for every 12 horizontal units the roof must rise a minimum of 2 vertical units. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. An example of a roof pitch would be a 6 12 pitch which means that the roof rises 6 for every 12 inward towards the peak or ridge.

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. Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot. A roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 pitch.

An example for a steep sloped roof is 8 12. This means that the rise of the slope goes up or down 8 inches for every 12 inches. Roof pitch or slope tells you how many inches the roof rises for every 12 inches in depth. Enter run the flat level length then click pitch angle or rise to select then enter other known dimension angle or pitch.

To put it in perspective the angle of this slope would be around 30 degrees. 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. 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. 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.

Asphalt shingles can only be installed on roof slopes of 2 12 or greater. There are two suggested ways to measure a roof pitch. The slope of a roof or pitch is determined by how many inches the roof rises over 1 foot or 12 inches. Or the colon can replace the slash as in 2 12 or 7 12.

Resilient asphalt shingles lie much flatter to the substrate than slate tile and concrete which keeps water from being easily blown under them. Sometimes pitch is also expressed in.
