Pitch of a roof math problem.
Roof pitch refers to the slope which the rafter creates.
Often you express roof pitch as the ratio between the rise and the run in the form of x 12.
For example given a roof with a rise of 4 feet and a span of 24 feet the pitch is 1 to 6 pitch which can be expressed as the fraction of 1 6.

In the uk the typical house has a pitch between 40 50 although 45 should be avoided.
In the usa the range of standard pitches is anywhere between 4 12 and 9 12.
Let the slope the hypotenuse c.
On the figure below the various permitted pitches for different roof materials are depicted.
Add 2 feet for overhang and you have 15 44 feet rounded off to be 16 feet for the rafters length.

A roof slope of 7 12 is also good and can provide the additional benefit of helping minimize the effects of wind driven rain.
This will be a right triangle.
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.
You can put this solution on your website.
The pitch fraction represents a certain amount of vertical rise over the entire span.
However from the wind uplift mitigation perspective a 7 12 roof slope can be considered as a two story building due to the higher overall steepness and profile of the roof.

A 12 to 24 pitch is expressed as 1 2.
Take 12 half the depth of the home x 1 120 and that equals 13 44 feet.
This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.
The roof s pitch is its vertical rise divided by its horizontal span or run called slope in geometry or the tangent function in trigonometry.
There is no standard universal roof pitch.

For example in the case of rolled metal roofs it can be a minimal of 5 as shown on the graph.
Roof pitch varies depending on culture climate style and available materials.
Take 16 x 64 60 feet long plus 2 feet overhang each end which equals 1 024 square feet for the front roof area.
Contemporary houses often have flat roofs which shouldn t be completely flat but should be around 1 40.
