under a rafter to find the pitch. This is a special tool and can also be used to find level, plumb, or any angle in between.Another method is to use a level and framing square from on top of the roof. Place a framing square on the up hill side of the roof with the body level...
To provide ventilation in a roof that is insulated, install special rafter vents. These are stapled to the underside of the roof sheathing, between rafters. They allow air to move behind the insulation so the roof stays nice and cold while the room inside is insulated against the cold. Make...
How to Cut Rafters with a Rafter Angle Square Determine the building’s width and length and the rafter span in order to evaluate how many rafters are needed. Then determine the pitch. Divide the rafter’s span by two to find the rafter’s run. As an example, a building that’s 24 ...
Definition of Rafter Span: the un-supported length of the rafter along its slope - the diagonal or hypotenuse of a right triangle. In our sketch the "rafter span" is referred to as the RAFTER LINE LENGTH. Definition of Roof Span: normally a roof span is the same as the building width ...
