Flat Shed Roof Pitch

Basically a slanted roof style is a flat roof tilted high up at one edge to create a very steep slope.

Flat shed roof pitch.

This image shows a relatively shallow roof pitch of 15 degrees. Significantly cheaper to build than a gable or multi slope roof since there s less material in the roof. In the case of a shed roof a layer of roofing felt usually. A flat roof is more likely to allow rain to pool and this can cause damage especially if the roof is made of a porous substance like wood.

Skillion roofs are one of the simplest roof styles used in shed building. 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. The reason for a pitched roof is to cause rain to run off the roof surface. Saltbox roofs look like skillion roofs but with an extra short slope opposite the long angled plane like an upside down check mark.

Having a steeper pitched roof allows for more space in a shed loft. The loft space would be much larger with a roof pitch of 45 degrees. It s similar to a shed or lean to roof or a clerestory roof but has one visible difference. As well the shallower the pitch the more you ll need to consider more moisture resistant roofing materials and underlayment.

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. A pitch of 10 degrees or less is typically regarded as a flat roof. A skillion roof is made up of a single flat plane which slopes gradually from top to bottom.
