Notching Roof Rafters

This trick worked for me.

Notching roof rafters.

Notching roof rafters to headers. Up here notching the gable end truss is common it is done to support the lookouts and fascia on the end of the gable. Measure as precisely as possible down to the 1 4 inch 0 64 cm 1 8 inch 0 32 cm or 1 16 inch 0 16 cm. Before you start cutting you first need to determine how long your roof rafters need to be and the angles at which you ll cut the top and bottom of the rafter.

The new roof will start at the back of the house go up to a peak and then down to rest on the entrance header to the kitchen. I cut rafters out of 2x8s frame this pole barn lean to. We are changing our flat roofs to peaked ones. If is wasn t for this joint a rafter or roofing joist would only balance on top of the wall plate making fixing difficult not to mention the fact that there wouldn t be any solid connection between the roof and the supporting walls below.

Please consult a professional before making any cuts i am not a professional framer or roofer nor do i claim to be. I noticed that the lumber don t know whether to call them joists or rafters comes down from the peak and they had to notch it. Using a block of wood as a ruler mark the ends for cutting. At the top where the rafters meet they are either angled to meet at a point or attached to a horizontal ridge beam.

If you ve wondered how to frame a lean to roof off a pole barn this video will show you how i did it. Each beam is notched at the bottom called a birdsmouth so that it rests flat on top of each wall. Use a tape measure to measure the entire width of your building. Birdsmouth joints cut into roofing rafters and mounted in place on top of the wall plate.

Then force the rafter s tip snugly against the house wall. More truss makers are switching to drop gables where the only notching is on the 2x6 outrigger itself.
