1 12 Slope Roof

Simply put it s a shallow roof.

1 12 slope roof.

If a roof rises 1 in a length of 12 this is 1 12 roof pitch. 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. Thus pitch is typically greater in areas of high rain or snowfall. The ratio can be indicated by a division slash separating the numbers such as 2 12 or 7 12.

Or the colon can replace the slash as in 2 12 or 7 12. Pitch is the term used to describe the angle slope or slant of your roof. 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. In degrees 10 2 in 12 or 1 in 6 is considered a minimum.

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. 1 12 roof pitch angle 4 76 degrees. A 2 12 roof slope means your roof has 2 inches of vertical drop for every 12 inches of horizontal distance. 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.

Most roof s have a pitch in the 4 12 to 9 12 range. A soldered flat seam metal roof won t be cheap and must be done by an artisan but it lasts a very long time. The exact roof slope in degrees is given by the arctangent. Metal roofing on 1 12 pitch the pitch is only 1 12.

Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio. 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. Definitions vary on when a roof is considered pitched. Roof pitch defined and explained.

This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. Low slope roofs have gradients of 3 12 or less. The table below shows common roof pitches and the equivalent grade degrees and radians for each. Arctan 3 12 14 0 the primary purpose of pitching a roof is to redirect water and snow.

In some very steep roofs you may see the gradient inverted so that the run varies but the rise is held as 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.
