Sloped Lean To Shed Roof Pitch

This slope works well for sheds that are fairly narrow like 4 to 6 feet but for sheds that are 8 or wider the shed roof becomes unsightly high.

Sloped lean to shed roof pitch.

This free roof pitch calculator will take your roof width see the picture and rise the height of the roof and will calculate the roof pitch both as numeric value. Roof pitch refers to the slope which the rafter creates. Often you express roof pitch as the ratio between the rise and the run in the form of x 12. You can assess this in two ways either as the roof pitch angles which the rafters make with the horizontal or the proportion between the run and the rise of the roof.

A relatively steep pitch in excess of 40 degrees to be waterproof. Remember roof pitch isn t just for aesthetics. Some builders even choose to match it directly especially if the shed s roof is attached to the house on the high side and just one simple span pitch. This means that for every 12 inches of horizontal distance across the shed the roof will rise 4 inches.

Asphalt shingles typically have a minimum slope rating of 4 in 12. More modern tiling and felt shingle systems can achieve lower slopes down to about 20 degrees. Another widely used method is to follow the house s roof pitch on one side building the ridge off center then sloping down more drastically on the shorter side which will be closer to the house. The roof is typically sloped down from the connecting wall if the shed is attached to the side of your house or garage.

The slope of your roof is vital as a moisture barrier among other things and having a roof that is too flat can potentially cause your shed to cave in. Furthermore a roof in a forest should have. However if you choose to build a freestanding shed and use this style of roof you should plan the slope of your roof in such a manner as to slope down from the front to the back of the shed. The run for a lean to shed rafter ending into a wall should account for the ridge board nailed into the wall where the tops of the rafters rest into.

Roof pitch calculator is great for calculating the pitch of your shed roof. The roof pitch measures the steepness of your shed roof and typically takes values from 1 to 12.
