This will be a right triangle.
In general slope y 1 y 2 x 1 x 2 y 2 y 1 x 2 x 1 now don t you wonder anymore about how to find the slope.

Find the pitch of the roof shown.
For example in the case of rolled metal roofs it can be a minimal of 5 as shown on the graph.
This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.
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.
Roof pitch varies depending on culture climate style and available materials.
Often you express roof pitch as the ratio between the rise and the run in the form of x 12.
There is no standard universal roof pitch.
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.
Roof pitch refers to the slope which the rafter creates.
Take 16 x 64 60 feet long plus 2 feet overhang each end which equals 1 024 square feet for the front roof area.
Find out how well you understand this lesson.
A roof slope of 7 12 is also good and can provide the additional benefit of helping minimize the effects of wind driven rain.
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.
Use the pythagorean theorem to solve.
The pitch fraction represents a certain amount of vertical rise over the entire span.
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.
Contemporary houses often have flat roofs which shouldn t be completely flat but should be around 1 40.

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.
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.
Add 2 feet for overhang and you have 15 44 feet rounded off to be 16 feet for the rafters length.
