Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot.
Pitch roof for 6 foot space.
A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally.
A roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 pitch.
However pitched roofs are still used as roof trusses are a very economic way of spanning between side walls.
So the pitch of a roof is determined by how many inches the slope rises for every 12 inches it runs horizontally.
So 2400 x 1 12 2 688 2 88 sqs added for pitch.
If a roof increases in height by four inches for every foot of horizontal run it is considered to have a 4 in 12 pitch or just a 4 pitch talk in terms of pitches and you will always be understood in the roofing universe.
Steeper roof pitches are better at shedding rain and snow and are used more frequently in wetter colder areas 2.
Most economical when the.
See the image below for more explanation on rise run and pitch.
Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs.
Our roof rafter calculator tools are handy for calculating the number of rafters needed rafter length calculator lineal feet of rafter board feed in ridge and sub facia and the total board feet in the roof.
Outside of the u s a degree angle is typically used.
Having a steeper pitched roof allows.
Angle the angle of a roof is the same as the roof s slope except instead of being.
Pitched roofs are attractive and also can be used for additional space for a shed loft.
Also in pairs with their high ends abutting on extremely long spans with a support underneath the high end.
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.
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 measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.
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.

Rise and run means that a 6 12 pitch roof has 6 of rise vertical for each foot of run horizontal.
It is often compared to slope but is not exactly the same.
Mono used where the roof is required to slope only in one direction.
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 12 in 12 pitch is a steep 45 degree angle roof.
