Shed roof framing is the process of constructing a solid frame to which a shed roof can be fixed. You can complete this without any input from a professional carpenter. This is because outside storage sheds are constructed with a flat roof or a low pitch, because no flat roof is entirely flat.
Step One – Measurements
Before any work can be carried out it is important that the shed construction is measured accurately. These measurements include the rise of the shed, which is the difference in measurements from the base of the shed to the top of the roofline at the front and back of the shed.
The span is the measurement along the longest side of the shed. The pitch will also need to be measured. This is the level of the roof and the minimum level for a shed roof is 3 inches and can be increased if snow and weather conditions are influencing factors within a particular region. Check relevant building codes, as they will provide information about the correct pitch for a shed roof.
Step Two – Rafters
The length of the rafters is determined by the size of the shed. Make sure they are an extra foot long for both the back and front of the building. For instance, if the shed construction is 10ft wide, then the rafters will need to be 12ft long. Use a hacksaw to cut a notch into the front and back of the rafters so that they will lay snugly into the front and back walls of the outdoor storage shed. The notches can be marked using a framing square, but it is essential that all of the rafters are identical to each other to promote a perfect fit.
Step Three – Installation
Before setting the rafters into place, use a framing square to mark out their desired location. The framing square will be able to measure the width of the rafters which will make it easier to mark out. Once the markings have been completed for all rafters, they can be put into place for the shed roof framing process.
Start at one end the shed construction and ensure that the notches allow the rafters to fit snugly into position on the front and back of the shed. Always use a long type of nail secure it into place. Repeat this process with all of the rafters.
Step Four – Framing
Secure lengths of fascia board to the rafters to complete the shed roof framing process. The boards should be the same length as the rafters. They should also be the same width as the rafters, but must also include spacing. For instance, if the rafters are 6 inches wide and are spaced 6 inches apart, then the fascia boards should be 12 inches wide. Once all the fascia boards have been installed, start applying the storage shed roof which will be made from asphalt rolls plus an underlayment.
