Using an online calculator.
How to figure out the slope of a roof.
Measure the rise of your roof.
Even if you want to use a flat roof pitch calculator system you will be able to find one.
Calculate the roof pitch as the proportion of rise and run.
Here are the steps to follow for the roof angle calculator.
This is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares.
To accurately calculate the area of your roof you must first determine its slope or pitch.
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.
Write the roof slope as the ratio of rise over run or vertical distance over horizontal distance.
If you want to know how to find the pitch of a roof then start with a calculator.
Then enter the value of the run and choose the unit of measurement from the drop down menu.
For example if your tape measure found a 6 inch vertical distance to the 12 inch mark on your level the slope is 6 12 or 6 in 12.
This will allow your project to carry the depth and detail in the roof that you wanted as well as make sure that it will maintain a sturdy and effective nature throughout.
The slope of your roof is the ratio of the vertical distance or rise of the roof to the horizontal distance or run.
The horizontal distance in the ratio will be 12 while the vertical distance is the measurement you took from the rafters.
Outside of the u s a degree angle is typically used.
That gives you 5 590 square feet which is the actual area of the surface of the roof.
A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally.
It is often compared to slope but is not exactly the same.
And that s the number you were looking for.
Take the area of the roof s footprint say it s 5 000 square feet and multiply 5 000 by 1 118.
Calculate the roof slope.
Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs.
Finally enter the value of the rafter length and.
For instance a 7 12 roof pitch means that the roof rises 7 inches for every 12 horizontal inches.
Let s say it is equal to 1 5 m.
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.
First enter the value of the rise and choose the unit of measurement from the drop down menu.
And for a roof with a slope of 6 12 that number 1 118 is your roof slope multiplier.
