Ways To Determine Pitch In A Roof

For example if a roof has a pitch of 4 12 then for every 12 inches the building extends horizontally it rises 4 inches.

Ways to determine pitch in a roof. You can also use these values with a roofing calculator. Divide the first part of the ratio by 12 to work out the pitch. The 7 means that the roof rises 7 for every 12 it runs. If you don t know the rise and run of your roof you will have to measure to get these values.

The pitch is commonly defined as the ratio of rise over run in the form of x 12. Before you calculate roof pitch you ll need to measure the slope of your roof. The rise is the height of the roof and the run is the horizontal span as pictured above. Simply mark a level at 12 hold it perfectly level and measure from the roof surface to your 12 mark this.

A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally. The roof pitch is the slope of the rafter. How do i calculate roof pitch. All you need to do is just enter the calculate button.

The easiest way to do this is by accessing a rafter in your attic if you can. Often you express roof pitch as the ratio between the rise and the run in the form of x 12. Example a the measurements are taken from on top of the roof. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs.

First of all you have to enter the value of the rise in the given place. To measure the roof pitch you ll need an 18 or 24 inch level a tape measure and a pencil.

Then in the attic place the end of the level against the bottom of a roof rafter and hold it perfectly level. 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.
