Hip to valley. the only method that is 100% foolproof to find the values for all jack rafters, no matter what the pitch or even if they are on different pitches is to physically measure the long rafter and the short rafter and then divide the difference by the number of spaces. this calculator returns the first 16 jack rafters.

How To Calculate Hip Valley And Jack Rafter Lengths Protradecraft More steps to calculate hips and jacks. [hip val] = hip and valley length again, excluding the tail: 22’ 4 ⅞”. if you punch [hip val] again, you get the plumb cut angle of 19.5 degrees. brrr. punching it again gives you the level cut or the seat cut—a much more civilized temperature. Just by putting in your roof’s pitch and run, the cm5 can calculate all of your jack rafters for you 🥳1️⃣ input the pitch and push the pitch button2️⃣ enter. There are 2 ways to calculate jack rafter lengths. whether you pull from the king common or the corner, the construction master pro makes these calculations. To lay out my jack rafters, i use a pattern made from a common rafter. so the first step in calculating the true length of the common rafters is adjusting the run for the thickness of the ridge (see "determine adjusted run," calculation above). the span of this building was 15 feet 8 13 16 inches. i subtracted out the 2x8 ridge (1 1 2 inches.

The hangers used to mount the valley jacks to the valley rafter are skewable. an unskewed one is lying flat on the floor beneath one i bent and tack nailed to the side of the valley rafter. using the skewable hanger eliminates the need to make an angle cut on the valley jacks. they can just be square cut to the short point measurement. Rafter length = run ÷ cos (angle) the rafter length is equal to the run divided by the cosine of the roof’s angle. another method is to use the rise of the roof using this formula: rise² run² = rafter length². meaning that your rafter length will equal:.
