On blue prints architects engineers usually display the pitch of a roof in the format shown on the image where number 4 represents a rise and number 12 represents a length.

Standard roof pitch degrees uk.

However if you to do the process using your own knowledge you can still convert pitch to degrees by dividing the rise and run and get its corresponding measurement. Although there is no single standard roof pitch used on all sloped roofs factors such as roofing materials and local climate help to determine the appropriate range of pitches for a given building. The table below shows common roof pitches and the equivalent grade degrees and radians for each. The pitch of your roof will not just have an effect on the way the house looks.

As a result the tiles must be able to cope particularly at the lower end of the slope with the greater expected volume of water and lower speed of water movement. The lower the pitch the greater the amount of water that the roof slope will collect and discharge. Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio. A pitch over 9 12 is considered a steep slope roof between 2 12 and 4 12 is considered a low slope roof and less than 2 12 is considered a flat roof.

This part is well known as slope in geometry tangent function or stair construction in trigonometry.

The picture below shows the pitch of a 7 12 roof slope meaning that for 12 of horizontal measurement roof run the vertical measurement roof rise is 7. Roof pitch is a measurement of a roof s slope expressed as a ratio. This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.

The roof pitch is described by the vertical rise divided by horizontal span. Contemporary houses often have flat roofs which shouldn.
