How do you work out pitch of a roof.

First find the slope by finding the tangent of the degrees eg. Then enter the value of the run and choose the unit of measurement from the drop down menu. Rafter rise run from the pythagorean theorem. If you can t get to your attic you can measure slope on your rooftop as long as it s safe to go up there.

After measuring the slope estimate the roof pitch by dividing the slope by 2 if you have a simple gable roof. The next step is to punch in 1 whatever your tangent is to find the angle of your roof pitch. The easiest way to do this is by accessing a rafter in your attic if you can. First enter the value of the rise and choose the unit of measurement from the drop down menu.

Pitch tan angle where angle is the roof pitch expressed in degrees. Then multiply the slope by 12 to get the rise. If you are trying to learn how to measure roof pitch calculations accurately you should really consider the importance of using a calculator. Slope tan degrees.

Once you have these two measurements you ll need to grab hold of a calculator and divide the rise by the run to work out the tangent. Either way it is important that you are safe when carrying out all measurements to avoid causing. Rise run pitch where pitch is expressed in percent. If you know the angle of the roof in degrees you can find the roof pitch by converting the angle in degrees to a slope then finding the rise by multiplying the slope by 12.

Before you calculate roof pitch you ll need to measure the slope of your roof. 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.
