Whats My Roof Pitch

 
How to Determine Your Roof Pitch

The angle, or pitch, of a roof is calculated by the number in inches the roof rises vertically for every 12 inches it extends horizontally. Your roof pitch is a measurement of the roofs rise in relation to the horizontal measurement of the roof, known as the run. Also known as 'rise over run'.

For example, a roof that rises 6 inches for every 12 inches of run is known as a six-twelve pitch, or 6/12.


Follow the steps below to find your roof pitch. This will inform you whether you will need a base extension on your cupola or not.

1. Print a Pitch Guide Below
Determine which set of pitches your roof pitch most resembles and print the image. If your pitch appears to fall somewhere around the 10/12 or higher range, you may want to print both.

Note: If your pitch is clearly shallow like the 4/12-7/12 pitches, you will not need to continue on. You will not need a base extension.



2. View Your Gable from a Distance
With the printed guide in hand, stand at a fair distance from your gable. Try to stand directly in front of the structure holding the guide up in front of you and select the pitch that best resembles your roof pitch.

3. Cut Along the Pitch Lines
Now that you have determined which pitch closest matches your roof pitch, cut this pitch out and from you vantage point see if you can visually fit the angle on the paper with your roof pitch.

4. Now You Know Your Roof Pitch
If your pitch falls at a 10/12 or below you will NOT need to purchase a base extension. If your pitch is 11/12 to 12/12, you will only need to purchase ONE base extension. If your pitch is 13/12 to 14/12, you will need to purchase TWO base extensions. 

Note: Our Shed Cupolas fit up to a 7/12 pitch, if your pitch is between 8/12 and 12/12, you will only need to purchase one base extension for the shed cupolas.
