The following diagram will let you easily convert roof pitch to degrees; a 7:12 pitch equals 30.26 degrees.
Is 7/12 A good roof pitch?
Roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run.

What is a 7 12 angle?
Answer: 7/12 roof pitch equivalents roof rises 7″ in a length of 12″. 7/12 roof pitch angle = 30.26 degrees.
What roof pitch is 45 degrees?
A 12/12 pitch roof has a pitch angle of 45°.
Which roof pitch is best?
Conventional slope roofs, with a pitch between 4/12 and 9/12, are the most common in residential work. Roofs with a pitch exceeding 9/12 (37 degrees) are termed steep slope roofs. In commercial work, low-slope roofs (with a pitch between 2/12 and 4/12) are most common.
What is the most common roof pitch?
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.
What is the angle of a 9 12 pitch?
Answer: 9/12 roof pitch equivalents roof rises 9″ in a length of 12″. 9/12 roof pitch angle = 36.87 degrees. 9/12 roof pitch angle to 36.87 degrees.
Is there a minimum roof pitch?
Traditionally, a minimum roof pitch of 20° was recommended in BS 5534, but modern tiles and slates have now been designed for applications as low as 15°. It is uncommon to find a roof below 15° but for those very low pitch applications, there are interlocking clay pantiles available, suitable for use down to 12.5°.
Is a 4/12 roof pitch good?
As well, a slope of 4:12 is most commonly considered the lowest slope for “standard shingle installations”. Most manufacturer and industry recommendations require, or at the very least recommend, special underlayment or other considerations on roofs between 2:12 and 4:12.
What angle is a 4.5 12 pitch?
This means if a roof rises 4′ in the length of 12′, your Roof Pitch would be 4/12 or 18.43 degrees.
What does a 4/12 pitch mean?
A roof that rises 4 inches for every 1 foot or 12 inches of run is said to have a “4 in 12” slope. … The slope ratio represents a certain amount of vertical rise for every 12 inches of horizontal run. For example, a “4 in 12” slope can be expressed as the ratio of 4:12. A “6 in 12” slope is expressed as 6:12.
What does a 2 12 pitch mean?
A 2/12 roof slope means your roof has 2 inches of vertical drop for every 12 inches of horizontal distance. Simply put, it’s a shallow roof. That means the roof doesn’t shed water as easily as steeper roofs, which is why choosing the right type of roofing material is so important.
What does a 4/12 roof pitch look like?
A 4/12 is a roof slope that rises by 4 inches for every 12 inches across. This forms an angle of 18.5° between the horizontal section and the roof, and creates a gentle incline that is seen as a midpoint between a low-pitch and medium-pitch roof.
