Pitch For Gable Shed Roof

The gable style pitched roof is not only one of the most common styles of shed roof but it is also one of the easiest to build.

Pitch for gable shed roof.

Roof pitch for the shed roof pictured above the back has a 5 12 pitch. Pitch for a gable roof the most common is generally 1 4 or 1 3. It can be made by bending plywood over ribs or arch cut rafters. You can do this by making a simple jig.

Don t forget to cut the ends of each board to the appropriate angle to allow them to fit together at the peak. If you have to go with a roof pitch less than 3 12 then it would either have to be a metal roof or a roof covered with a rubber membrane to prevent water penetration. Consider different roof designs when building a shed but understand that pitch is pitch whether you have a 3 12 gable roof or lean to roof the physics of moisture penetration won t change even though the style is different. For instance a 4 12 pitch denotes a roof rising 4 inches for each 12 inches.

The loft space would be much larger with a roof pitch of 45 degrees. Read this post if you want to change the roof pitch to 4 12 or 5 12 make the trusses now because you ll need two of them to build the gable end walls in the next step. The flip side to this is that it also becomes more expensive to build both in materials and logistical difficulty. A gable roof has the same pitch on each side as well as the same length.

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. Whereas a hip roof and other popular roof types have at least two sides the shed roof has a single slope that can vary in steepness depending on the design. It s important that all your trusses be the same height and width so that the ridge line of your new shed will be symmetrical.

This image shows a relatively shallow roof pitch of 15 degrees. Which is equal to 1 4 or 1 3 the total span of the building not counting any overhang. This is based on how much rain and snow you are likely to get in an average year. Having a steeper pitched roof allows for more space in a shed loft.

Think of a shed roof as a flat roof at a steeper slope you can also think of it as one half of a traditional gable roof. A curved shed roof design offers a mix of the flat and gable roof style creating the curve or arch. It is often used to increase headroom without adding much height. Pitch also has its own denotation determined by the rise in inches in 12 inches.
