1 12 Slope Roof

Mineral surfaced roll roofing can only be installed on roof slopes of 1 12 or greater 8 slope.

1 12 slope roof. Roof slopes are identified using the gradient method described above where the rise varies but the run is usually 12. 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. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio.

To obtain an accurate roof pitch measurement properly measure the rise and run. This means for every 12 horizontal units the roof must rise a minimum of 1 vertical unit. 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. What is a 1 12 roof pitch if a roof rises 1 in a length of 12 this is 1 12 roof pitch.

1 12 roof pitch angle 4 76 degrees. Using a tape measure make a pencil mark 12 inches from the end of a carpenter s level.
