Abstract
The foreman of one of my first framing jobs asked me if I knew how to build a California roof. I didnt', but soon learned. When framing two gable roofs that meet at right angles, and when one of the roofs has a lower ridge than the other, the common approach is to use a supporting valley rafter that extends from the wall plate to the main roof ridge, and a shorter nonsupporting valley rafter that intersects it. But jack rafters must then be cut. The blind valley, or California roof, is less complicated. The technique makes sense when framing an addition because the new roof can be framed directly on the old roof. It also works well on new construction. The article shows how to build one roof on top of the other and skip the valley rafters.
