Double Gable Roof Valley

An m shaped roof is double pitched roof.

Double gable roof valley.

To build your gable roof you ll need wooden boards cut into joists rafters supports and a ridge board in addition to sheathing felt paper and shingles. Determine the gable pitch. The valley rafter is marked for a 12 in 17 pitch and then cut with a double bevel to fit into the ridge intersection. Keeping all of the crowns pointing up prevents waves from marring the finished roof.

Where two gable roof lines meet the intersection forms inside corners called valleys. The roof rests on two bearing walls with two sloping walls meeting in the middle to form an m shape. Sheathing blocking is added along the valley and the sheathing pieced in for both roof planes. At the low end of the valley the subfascias of the two roofs are mitered with a block filling in the roof framing.

In order to shingle this kind of roof valley a roofing professional has to install both roof faces at the same time which is quite slow.

To transition the eaves the horizontal fascia extends to the last rafter tail and a vertical return finishes the transition. Essentially a double gable.

A gable roof is a simple symmetrical triangular roof. Because most framing lumber is not perfectly straight i check each piece and mark the crown before i start cutting the lumber into rafters. Valleys are typically found where gable dormer roofs meet the main roof or when a house has angled wings or additions where two roof sections in different planes meet. Provide some drainage slope if the two gable sides will intersect at a valley.

Both sides can slope the same or have differing pitches often done in craftsman houses. If repairs are needed the contractor has to remove and then reweave multiple shingles to replace a single one. The valley area of a roof the straight lines formed when two different planes of the roof meet is a critical area that handles a tremendous amount of water run off.
