Picture of ridge line meeting a roof valley.

The three methods to shingle a roof valley. The top end of each rafter is cut at an angle so that it meets flush with one broadside of the ridge board and the ridge is sandwiched between the rafters. Blind valleys simplify framing. If you re saying they should be off center please explain.

To keep the porch roof framing as simple as possible we installed a structural ridge supported by posts at each end with the common rafters landing on top of the ridge. Part 1 a guide to roof construction covers an overview of flat and pitched roofs. Your observation is correct about the h v line meeting the inside corner of the fascia instead of the outside. This recommendation includes iko s premium shingles.

This type of roof is also called broken back hip and valley roof because the main hips are intconeected by the rafter of gables on one side and the rafter of the valley on the other. A hip and valley roof may be part of an irregular structure. Part 3 of the four part guide to roof construction covers pitched roof detail. Using a pitch measuring tool that i d made we also determined that the exact pitch of the shed roof was 3 1 2 in 12.

Ridge boards and beams. In traditional house framing also called stick framing a basic roof frame consists of opposing pairs of sloping rafters that meet at their top ends at a ridge board or ridge beam. Such buildings may have more than four hips in the roofs and they form valleys at the inside corners. The hip valley members are 1 1 2 thick and my intent was to show the bottom surface of roof sheathing meeting at their centers.
