1 12 Slope Roof

If a roof rises 1 in a length of 12 this is 1 12 roof pitch.

1 12 slope 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. At 1 12 pitch you are right at the threshold where standing seam becomes impermissible i mean true standing seam with a rolled lock seam and soldered flat seams must be used. Metal roofing on 1 12 pitch the pitch is only 1 12. The table below shows common roof pitches and the equivalent grade degrees and radians for each.

The exact roof slope in degrees is given by the arctangent. I have read some articles that state this type of metal will work fine and others that implicitly state not to use metal for such a low pitch. Roof slopes are identified using the gradient method described above where the rise varies but the run is usually 12. Low slope roofs have gradients of 3 12 or less.

Simply put it s a shallow roof. 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. Pitch is the term used to describe the angle slope or slant of your roof. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.

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. A very low pitch roof can also be done in metal. 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. In degrees 10 2 in 12 or 1 in 6 is considered a minimum.

Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio. A 2 12 roof slope means your roof has 2 inches of vertical drop for every 12 inches of horizontal distance. Most roof s have a pitch in the 4 12 to 9 12 range. Roof pitch designations are comprised of two numbers indicating a ratio.

Arctan 3 12 14 0 the primary purpose of pitching a roof is to redirect water and snow. Roof pitch defined and explained. 1 12 roof pitch angle 4 76 degrees. Or the colon can replace the slash as in 2 12 or 7 12.

The ratio can be indicated by a division slash separating the numbers such as 2 12 or 7 12. In some very steep roofs you may see the gradient inverted so that the run varies but the rise is held as 12.
