For a 6-in-12 roof, mark 12 in. on one side for the rise and 24 in. on. the other edge for the run. Connect the marks to complete the triangle.Oct 22, 2018 · The bearing walls that are parallel with to a ridge beam must have the stiffness to resist the the outward pressure exerted on the walls by the joists. This can be provided by horizontal ceiling rafters that connect between the walls or a concrete block wall with a tie beam. So a ridge board does not have to be supported. In a roof with a structural ridge beam, there is not lateral thrust, i.e. the rafters aren't trying to push the walls out. The roof load is carried on the ridge and on the walls, and there is no need for collar ties or ceiling joists to resist lateral thrust. In a roof with a ridge board, there is lateral thrust.

Create a brace for your ridge board by nailing a 2-by-4 board up the center of the gable-end wall. The board should measure taller than the wall and roof rise combined.

This can be provided by horizontal ceiling rafters that connect between the walls or a concrete block wall with a tie beam. So a ridge board does not have to be supported. Ridge Beam Calculation Formula. RidgeBeamLoad = (RoofLoadArea * UnitLoad) / BeamLength. Where: RoofLoadArea is the total roof area supported by the beam. UnitLoad is the combined dead and live load per square foot. BeamLength is the length of the beam in feet. Ridge Beam Calculation Formula. RidgeBeamLoad = (RoofLoadArea * UnitLoad) / BeamLength.

BeamLength is the length of the beam in feet.If you have a 30-foot span, it is important to know just how long a beam you will need for support. There is a good rule of thumb for this: divide your span (in inches) by 20. So, if your span is 30 feet (or 360 inches) you would divide that by 20 to come to 18 feet. Generally, it will be between a third and half of your overall depth.Saw. Installing the Ridge Beam: Step-by-Step. Positioning: Begin by placing the ridge beam horizontally along the roof’s peak.
