Notching roof rafters. 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. 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. This trick worked for me. A ridge beam runs the length of the shed roof connecting every pair of rafters.

Then force the rafter s tip snugly against the house wall. 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. At the top where the rafters meet they are either angled to meet at a point or attached to a horizontal ridge beam. Use a tape measure to measure the entire width of your building. Each beam is notched at the bottom called a birdsmouth so that it rests flat on top of each wall.

Notching roof rafters to headers. Since the webbing in the truss is vertical it is considered by building inspectors to be ok.
