Pitch For Gable Shed Roof

The first thing you need to do is determine the correct pitch for your area.

Pitch for gable shed roof.

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. Having a steeper pitched roof allows for more space in a shed loft. 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. A curved shed roof design offers a mix of the flat and gable roof style creating the curve or arch.

Pitch also has its own denotation determined by the rise in inches in 12 inches. 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. 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.

The loft space would be much larger with a roof pitch of 45 degrees. This image shows a relatively shallow roof pitch of 15 degrees. For instance a 4 12 pitch denotes a roof rising 4 inches for each 12 inches. Don t forget to cut the ends of each board to the appropriate angle to allow them to fit together at the peak.

Pitch for a gable roof the most common is generally 1 4 or 1 3. If you re planning on building a gable roof with a pitch of 4 12 for a shed that s 200 inches 510 cm wide your rafter boards would need to be 105 3 inches 267 cm long on each side. The flip side to this is that it also becomes more expensive to build both in materials and logistical difficulty. Roof pitch for the shed roof pictured above the back has a 5 12 pitch.

This is based on how much rain and snow you are likely to get in an average year. It can be made by bending plywood over ribs or arch cut rafters. Which is equal to 1 4 or 1 3 the total span of the building not counting any overhang. 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.

Basically the steeper the pitch the better it can shed snow and rain. 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. You can do this by making a simple jig. It is often used to increase headroom without adding much height.
