First, find the slope by finding the tangent of the degrees, e.g. slope = tan(degrees). Then multiply the slope by 12 to get the rise. You can then express the pitch as inches per foot.
Simply so, How do you find the rise and run pitch? How to Calculate Roof Pitch in Degrees
- First, you need to measure the run of your roof. …
- Next, you need to figure out the rise. …
- Now, divide the rise by the run. …
- Then, divide 1 by your tangent.
- Finally, multiply this result by 180/π and you’ve calculated your roof pitch!

Subsequently, What is a 12 6 roof pitch?
Roof pitch (or slope) tells you how many inches the roof rises for every 12 inches in depth. An Example of a roof pitch would be a “6/12 pitch” which means that the roof rises 6 ” for every 12″ inward towards the peak (or ridge).
Can the run be negative?
When calculating the rise of a line’s slope, down is always negative and up is always positive. When calculating the run of a line’s slope, right is always positive and left is always negative.

What is the minimum pitch for a lean to roof?
The smallest pitch of a roof is 1/4:12, which translates to 1/4 inch rise to 12 inches of run. Such a small pitch can only work with built-up roofing or specialized synthetic roofing. Covered porches that are near trees or in areas with heavy rains should not be covered with a low-slope roof.
What is a good pitch for a shed roof? As well, seams are often elevated at least 2” off the surface of the roof and, thus, away from moisture. What is this? A quarter-inch slope is the lowest you would go with a metal roof – experts recommend at least a half-inch minimum to ensure a weatherproof interior for your shed.

What is the most common roof pitch? Conventional slope roofs are most common with residential roofs. This means the slope has a pitch between 4/12 and 9/12 on most homes. Roofs with a pitch exceeding 9/12 are called steep slope roofs.
What is a 512 pitch?
What is a 5/12 roof pitch? 5/12 or 5 on 12 roof pitch is define as roof rafter that vertical rises 6 inches for every 1 foot or 12 inches of horizontal distance or run is said to have a “5 on 12” slope, “5 in 12” slope or 5/12 roof pitch and their pitch roof angle is about 22.62°.
What is the most common roof pitch angle?
The most commonly used roof pitches fall in a range between 4/12 and 9/12. Pitches lower than 4/12 have a slight angle, and they are defined as low-slope roofs. Pitches of less than 2/12 are considered flat roofs, even though they may be very slightly angled.
Is Rise Over Run always positive? If the slope is positive, then the rise and the run need to either be BOTH positive or BOTH negative. In other words, you will be going up and to the right OR down and to the left. … If the slope is negative, then the rise and the run have to be opposites of each other, one has to be positive and one has to be negative.
Does rise or run go on top?
If you « rise up », the number is positive; if you « rise down », the number is negative. Now, you ALWAYS « run over »! If you follow the procedure correctly, you will always run over to the right.
How do you graph a rise over run?
How many degrees is a 4/12 roof pitch? Roofs with a pitch of 4/12 are approximately 18.4 degrees, depending on how exact you’d like to be in your measurement. Check out our roof angle chart for more examples of the exact angles (expressed in degrees) of common roof pitches.
What is the lowest slope for a metal roof?
The minimum slope for a metal roof with exposed fasteners and seams without sealant is 3:12, which means 3” of drop for every 12” of horizontal run. Roofing with exposed fasteners and lapped seams with sealant can go lower – ½:12.
How many degrees is a 5/12 roof pitch?
| Roof Pitch Degree Table | |
|---|---|
| 1-12 | 4.76° |
| 5-12 | 22.62° |
| 6-12 | 26.57° |
| 7-12 | 30.26° |
Do flat roofs have a slope?
A flat roof is a roof which is almost level in contrast to the many types of sloped roofs. The slope of a roof is properly known as its pitch and flat roofs have up to approximately 10°. Flat roofs are an ancient form mostly used in arid climates and allow the roof space to be used as a living space or a living roof.
Do roof pitches have to match? Unless you’re absolutely sure of the effect you’re after, avoid combining different roof pitches. More often than not, varied pitches look disorganized or, worse, like a construction error. Stick to a uniform pitch, and rely on the size and arrangement of roof masses for effect.
