Gable roof lookouts.

In wood frame construction the primary structural members of a gabled roof frame are the ridge board and the rafters. The procedure for erecting a simple gable roof. Typically in a more conventional roof you d support the barge with lookouts but in this situation there are 2 rafters outside the walls on each side 3 overhang 2 oc rafters so lookouts don t make sense if they ever do with i joist construction so best i can tell is that the rim fascia is supporting the outer two rafters. After the gable is framed lookouts extend from the first rafter inside the gable wall out over the plates to support the overhanging barge rafter.

Framing a dropped gable wall one of the keys to framing the rake with my system is building a dropped gable end wall the top of which is 3 1 2 inches below the tops of the rafters. A gable roof consists of two sloped planes that meet at the ridge or peak and rest on the top plates of 2 parallel exterior walls. If a truss roof is used with this method the gable truss is manufactured 3 shorter than the others. A horizontal timber or metal resting at the peak of the roof the rafters and trusses are connected to the ridge board for a cohesive framework.

Section 2 1 3 4 c states rake overhangs shall not exceed the lesser of one half the purlin length or 2 feet and makes an exception for rake overhangs using lookout blocks which shall not exceed 1 foot design of gable rake overhangs may also have an impact on the design of the framing of the gable below. Then the barge or fly rafter is attached to the end of the cantilevered outlooker.
