How To Figure Out The Slope Of A Roof

Pitch rise run 1 5 6 25.

How to figure out the slope of a roof.

First enter the value of the rise and choose the unit of measurement from the drop down menu. Measure the rise of your roof. The slope of your roof is the ratio of the vertical distance or rise of the roof to the horizontal distance or run. 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.

Here are the steps to follow for the roof angle calculator. Calculate the roof pitch as the proportion of rise and run. Using an online calculator. For instance a 7 12 roof pitch means that the roof rises 7 inches for every 12 horizontal inches.

It is often compared to slope but is not exactly the same. 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. Rafter rise run 1 5 6 2 25 36 38 25rafter 38 25 6 18 m. The horizontal distance in the ratio will be 12 while the vertical distance is the measurement you took from the rafters.

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. Calculate the roof slope. That gives you 5 590 square feet which is the actual area of the surface of the roof. Calculate the rafter length substituting these values into the following formula.

Then enter the value of the run and choose the unit of measurement from the drop down menu. Write the roof slope as the ratio of rise over run or vertical distance over horizontal distance. Take the area of the roof s footprint say it s 5 000 square feet and multiply 5 000 by 1 118. A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally.

If you want to know how to find the pitch of a roof then start with a calculator. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs. Outside of the u s a degree angle is typically used. Finally enter the value of the rafter length and.

Even if you want to use a flat roof pitch calculator system you will be able to find one. And that s the number you were looking for. Let s say it is equal to 1 5 m. To accurately calculate the area of your roof you must first determine its slope or pitch.
