There are advantages and disadvantages to having a steep pitch versus a shallow, or low, pitch_,_ the most obvious of which is the roof's ability to shed or withstand heavy snow, rain or wind. basically, the steeper the pitch, the better it can shed snow and rain .. Gable shed roof framing a gable style is the easiest to build, but offers very little storage in the attic. unless of course you have a very steep pitch on your trusses or rafters.. Shed the shed roof, or lean-to, is a roof having only one slope, or pitch. it is used where large buildings are figure 2-2.—roof framing terms. 1/8 pitch is given, so 24 x 1/8 equals 3, or unit of rise in inches. if the unit of rise in inches is 3, then the cut is when the rafter is in its proper position. framing square learning.
How to determine the pitch for a shed roof rafter. sometimes it's necessary to cut a shed roof type rafter when you only know the height of the knee-wall or the difference between the two walls and the run. difference in height in inches divided by run in feet = pitch .. Mono-pitched roofs (pitched here means a roof plane rather than a slope and implies it is not a flat roof) mono-pitched roof (shed, skillion, lean-to roof): a roof with one slope, historically attached to a taller wall.. However, minimum slope for a flat roof by building code here is 2%. (1/4" per 1'). you have more than enough slope for your roof, however you will likely need some sort of membrane roofing since it is very low slope. there are profiled metal roof cladding systems specifically designed for low-slope application..
