How To Work Out The Slope Of A Roof

Remember to convert units so they are the same.

How to work out the slope of a roof.

You can obtain all the necessary values for the pitch of a roof a drainage slope a steep path an access ramp etc. It can be measured as an angle in degrees radians or gradians or as a percentage the width to height ratio multiplied by 100. Outside of the u s a degree angle is typically used. For instance a 7 12 roof pitch means that the roof rises 7 inches for every 12 horizontal inches.

If you are trying hard to work out how to figure roof pitch measurements the calculator takes away all of those problems for you more or less instantly. Roof slope calculator example of use. Calculate the roof slope. If you are trying to learn how to measure roof pitch calculations accurately you should really consider the importance of using a calculator.

The method that follows may not be the most mathematical way to work out the ratio gradient of a slope but it is really simple and has always worked for me. There are a number of ways that you can calculate the roof slope of your home and you need to be aware of this. 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. Roof pitch is used to describe the slope or angle of the roof.

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. Find the inverse tangent of the pitch to find the angle in degrees. Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot. Let s assume it is equal to 6 m.

It is often compared to slope but is not exactly the same. Angle the angle of a roof is the same as the roof s slope except instead of being. 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. Divide the first part of the ratio by 12 to work out the pitch.

The roof pitch is important in determining the appropriate installation method and how much roofing material will be needed. Roof pitch calculator results explained. To work out the gradient of an existing slope you will need the distance of the slope run and the height of the slope rise. Measure the run length it is the horizontal distance between the roof ridge and the wall of the building.

When you want to replace or repair your roof you need to know about the slop of the roof the reason for this is the simple fact that roof slope can affect the overall cost of replacing or repairing the roof. Write the roof slope as the ratio of rise over run or vertical distance over horizontal distance.
