Lean To Shed Roof Pitch

If the roof pitch is very steep at all then it will rise to a height that becomes unsightly.

Lean to shed roof pitch.

This ugly design is most often avoided by installing a low slope roof to keep the rise of the roof at a minimum. Pitched roofs can also be used to incorporate roof lights angled in a specific direction or dormer windows. Much depends on what your intended use for the shed actually is. 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.

Lean to shed roofs develop an interesting problem as they get larger. Some may say it is ugly. The loft space would be much larger with a roof pitch of 45 degrees. I cut rafters out of 2x8s frame this pole barn lean to.

When all the 2 4 s are cut that need to be build the roof framing according to your blueprint tip. As stated in the video speed squares have useful markings on them from 0 to 12. Remember that pitch is calculated as the height or rise of a roof pitch over 12 inches of horizontal run. If you are only trying to keep a wood pile dry or storing a few outdoor tools and light machinery out of the weather then you might consider a simple single pitch roof since most everything inside will be stored at ground level and pulled out from the outside of the shed.

Basically a steeper pitch is better at shedding rain and snow. Often you express roof pitch as the ratio between the rise and the run in the form of x 12. Roof pitch refers to the slope which the rafter creates. Therefore if your roof rises 4 inches over the course of 12 inches of horizontal run then your roof pitch is 4 12.

Having a steeper pitched roof allows for more space in a shed loft. This image shows a relatively shallow roof pitch of 15 degrees. In other words if there is a 1 1 2 ridge board nailed into the wall and the width of the lean to is 96 then the run will be 94 1 2 96 1 1 2 94 1 2. 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.

It will be easier to build this in place on top of the shed but if you can t build it on the ground then put into place before adding the sheathing. If you ve wondered how to frame a lean to roof off a pole barn this video will show you how i did it. There are advantages and disadvantages to having a steep pitch the most apparent of which is the roof s ability to withstand or shed heavy rain snow and wind.
