How To Decide A Roof Angle For Basic Shed

If you ve chosen to build a backyard shed yourself rather than buying a premade model from a hardware store you re going to have to decide on a shed roof design.

How to decide a roof angle for basic shed.

As a guiding point remember that with a pitched roof each truss is going to be triangular in shape. This is the geometric shape that will provide the greatest stability. These are also the most common pitches for shed roofs. Use a handy tool like snow load calculator to help you determine if your roof can handle the weight of snow based on its pitch.

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. Beyond that you re free to choose whatever slope best fits your plans for your shed. This free roof pitch calculator will take your roof width see the picture and rise the height of the roof and will calculate the roof pitch both as numeric value. Any roof from 4 12 to 9 12 is considered an ordinary angle for a roof.

A slope of 6 12 for example means that for every 12 inches 30 cm of length the angle of your roof rises 6 inches 15 cm. If your roof pitch is greater than 3 your roof is considered pitched read more about roof pitch at wikipedia. Whichever roof pitch you choose make sure that you select a roof covering that is designed to be waterproof at the angle that you eventually select. There will typically be a 30 degree angle at the top of the peak and then a 60 degree angle at the point where the truss meets the wall.

The roof pitch measures the steepness of your shed roof and typically takes values from 1 to 12. Some builders even choose to match it directly especially if the shed s roof is attached to the house on the high side and just one simple span pitch.
