2 12 Roof Pitch Angle

A steep roof usually sheds water quickly which is quite difficult to work on.

2 12 roof pitch angle. Often you express roof pitch as the ratio between the rise and the run in the form of x 12. Pitch angle incline slope they all can be used to refer to the steepness of a roof. Roof pitch basics a 2 12 roof slope means your roof has 2 inches of vertical drop for every 12 inches of horizontal distance. Two most common methods 4 12 or 4 12 are used for marking the pitch of a roof.

This is the slope of geometry stairways and other construction disciplines or the trigonometric arctangent function of its decimal. 2 12 roof pitch angle 9 46 degrees. The pitch of a roof is its vertical rise over its horizontal span. 45 this is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations.

That means the roof doesn t shed water as easily as steeper roofs which is why choosing the right type of roofing material is so important. Roof pitch defined and explained. 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. Most roof s have a pitch in the 4 12 to 9 12 range.

Enter any pitch or fraction of pitch to find angle. Enter any angle or fraction of angle to find pitch. Generally such roofs have a pitch ranging from 1 2 12 to 2 12. Common roof pitches and equivalent grade degree and radian angles.

The combination of two numbers are used to display or show the roof pitch. Roof pitch designations are comprised of two numbers indicating a ratio. In the roofing trade the go to term is pitch and it is expressed in terms of 12 inches so the pitch of a roof is determined by how many inches the slope rises for every 12 inches it runs horizontally. Or the colon can replace the slash as in 2 12 or 7 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 ratio can be indicated by a division slash separating the numbers such as 2 12 or 7 12. The roof pitch angle greatly factors into the replacement cost 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.

However most often a ratio of pitch also fraction is slang used for the more useful slope of rise over run of just one side half the span of a dual pitched roof. If a roof rises 2 in a length of 12 this is 2 12 roof pitch.
