WebMar 9, 2024 · Suppose the base of the actual roof is measured to be 40 feet. You can set up the following equivalence: base of triangle/base of actual roof = hypotenuse of triangle/hypotenuse of roof. Plugging in the numbers, you get 1/40 = 1.06 /x, where x is the required rafter length. Solving for x, you get x = (40) ( 1.06) = 42.4 feet.
