Shed roof pitch chart.

Knowing how to calculate roof pitch rise run and ridge board height is essential to any shed construction. Set the level on the edge of the speed square as shown below then place the heel of the speed square on a rafter or gable edge of the roof. A 12 in 12 pitch is a steep 45 degree angle roof. Rafter length using pitch v r 2 sqrt 1 p 2 where v overhang r roof span p pitch use our online rafter length calculator to quickly compute the length of the shed roof rafter by entering the measurements of overhead length of roof span pitch or angle.

A speed square and level can be used to easily find the pitch of a roof. A roof pitch calculator can make things much easier. 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. The roof pitch calculator is a convenient online tool you can use to quickly assess the pitch of your roof to determine the length of rafters you need.

The calculator above can handle much of this math. A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally. Much depends on what your intended use for the shed actually is. The minimum roof pitch for shedding snow is around 30 or a 6 12 or 7 12 slope although this is not a definite as the material of your roof the direction of the snow and wind are some factors that can affect whether or not snow will slide as roofs of as little as 10 have been reported to shed snow.

Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs. The roof pitch measures the steepness of your shed roof and typically takes values from 1 to 12. Measure with a speed square. Simply plug in the values of your roof and it will show you slope percentage degree and even length.
