Shed Roof Pitch For Snow

Therefore if your roof rises 4 inches over the course of 12 inches of horizontal run then your roof pitch is 4 12.

Shed roof pitch for snow.

This is based on how much rain and snow you are likely to get in an average year. The first thing you need to do is determine the correct pitch for your area. Having a steeper pitched roof allows for more space in a shed loft. A medium pitched roof is one that has a pitch of between 3 12 and 7 12.

This range makes up the bulk of new roofs being built on homes and outbuildings in the u s. 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 safely measure the roof pitch from inside your attic with a level that is either 18 or 24 inches a tape measure and a pencil. If you live in an area with a lot of annual snowfall consider creating a also remember that metal roofs tend to shed snow more easily than shingled roofs.

The slope that works best seems to be 5 12. Constructing a new shed roof at the desired pitch is as easy as knowing how to use a speed square. Remember that pitch is calculated as the height or rise of a roof pitch over 12 inches of horizontal run. Steeper roof pitches are better at shedding rain and snow and are used more frequently in wetter colder areas.

Once in the attic hold your level against the bottom of a roof rafter ensuring that all bubbles are resting in the center. As stated in the video speed squares have useful markings on them from 0 to 12. This allows the snow to stay on while venting the roof system. 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.

Basically the steeper the pitch the better it can shed snow and rain. Pitched roofs are attractive and also can be used for additional space for a shed loft. The higher the roof pitch the more often the snow slides off. So in general the shallower pitch can be more dangerous with bigger slides.

The flip side to this is that it also becomes more expensive to build both in materials and logistical difficulty. Snow tends to accumulate more on roofs with pitches of 14 degrees or less 3 12 or less because it cannot easily slide off. They also plan to use the snow as an insulation blanket and design a cold roof system to stop ice dam concerns at the eave. Begin by measuring 12 inches on your level and marking it with a pencil.
