Sheathing blocking is added along the valley and the sheathing pieced in for both roof planes.

A truss base is a closed polyline that defines the area in which valley fill roof trusses are to be built across and above the tops of normal full size roof trusses. All four valleys formed by the intersection converge at a central peak. A disadvantage of the hip roof is that it is more difficult to construct than a gable roof. Type of roof because it is braced by four hip rafters.

The rise or height of the roof at its peak is the altitude of the triangle. Intersecting the intersecting roof consists of a gable and valley or hip and valley. And the line length measurement from the roof peak to the building wall is the hypotenuse. After they re up you can snap a line to mark and trim the tails in a nice straight line to make up for any ridge warp or marking cutting and fixing errors.

In a pure cross gable roof two ridges both at the same elevation intersect at 90. The valley is formed where the two different sections of the roof meet generally at a 90 angle. At the low end of the valley the subfascias of the two roofs are mitered with a block filling in the roof framing.
