A 4 12 pitch is around 18 5 degrees but not exactly.
Degree lean to roof pitch.
Roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run.
But since there is still a wide variety of slate roofing systems there are occasions when the minimum pitch can go down to as low as 15 0 depending on the uniqueness of the roof.
Although there s isn t any standard pitch of a roof used on all kinds of sloped roofs you can determine the range of pitches by using a roof angle calculator and by considering factors like the local climate and roofing materials.

Angle the angle of a roof is the same as the roof s slope except instead of being.
Roof pitch calculator results explained.
Most roof s have a pitch in the 4 12 to 9 12 range.
In the usa the range of standard pitches is anywhere between 4 12 and 9 12.
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.
To put it in perspective the angle of this slope would be around 30 degrees.
The slope of a roof or pitch is determined by how many inches the roof rises over 1 foot or 12 inches.
Thus a 4 12 pitch would be a 33 slope.
Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio.
Enter this measurement into the calculator and select a roof pitch and the length of the rafter will automatically returned along with the rise.
An example for a steep sloped roof is 8 12.
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.
You can also divide the rise over run multiply by 100 and get a percentage.
Contemporary houses often have flat roofs which shouldn t be completely flat but should be around 1 40.
This means that the rise of the slope goes up or down 8 inches for every 12 inches.
The table below shows common roof pitches and the equivalent grade degrees and radians for each.
A ratio is the most common way of expressing roof pitch or roof slope but degrees are also possible.
