Notching Roof Rafters

Up here notching the gable end truss is common it is done to support the lookouts and fascia on the end of the gable.

Notching roof rafters.

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. 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. Then force the rafter s tip snugly against the house wall.

This trick worked for me. Each beam is notched at the bottom called a birdsmouth so that it rests flat on top of each wall. Using a block of wood as a ruler mark the ends for cutting. 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.

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. To cut sloping rafters for a house attached patio roof lay a rafter board so it rests on its edge on both the ledger and the beam parallel to the ledger. More truss makers are switching to drop gables where the only notching is on the 2x6 outrigger itself. I cut rafters out of 2x8s frame this pole barn lean to.

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. Birdsmouth joints cut into roofing rafters and mounted in place on top of the wall plate. At the top where the rafters meet they are either angled to meet at a point or attached to a horizontal ridge beam. Since the webbing in the truss is vertical it is considered by building inspectors to be ok.

A ridge beam runs the length of the shed roof connecting every pair of rafters. Notching roof rafters to headers.
