Then, trace the short side of the framing square with a pencil to mark the tail cut. After you’ve done that, rotate your framing square 180 degrees so that the 8-inch mark on the long side of the framing square intersects the line for the tail cut. Make sure the other stair gauge is resting against the rafter and use your pencil to trace the length of the tongue. Then, reposition your framing square so that the stair gauge of the tongue is on the pencil mark you made to indicate the full diagonal length of the rafter. Once you’ve marked the lines, use your pencil to draw the diagonal length on the rafter. Next, set the framing square on top of the rafter beam and use a pencil to trace the outside edge of the framing square’s tongue. To cut roof rafters, start by fixing the stair gauges on your framing square to the dimensions of your pitch. The calculator (or math equation, if you’re writing it out longhand) will only calculate the diagonal measurement to the edge of the building. Keep in mind that, if you want your rafters to overhang past the edge of the building wall, you’ll need to add that measurement in separately.For example, there’s a free roofing calculator at. If you’d rather not purchase one, there are many available for free online. Roofing calculators are commonly used by professionals.You’ll also need to purchase a copy of a roofing ready reckoner: a manual with rafter length tables. If you’re not using a roofing calculator, you’ll need to perform some complex trigonometry to calculate the rafter length.In this example, it will be 39.81 inches (101.1 cm). Press the “Diagonal” key, which will calculate the diagonal measurement between your structure’s outside wall and the top of the ridge beam. If you’re using a roofing calculator, it will use the information you’ve already input (run measurement and pitch) to calculate the length for each rafter.
