Gable Roof Lookouts

The procedure for erecting a simple gable roof.

Gable roof lookouts.

The original gable roof lookout was built in 1932 and replaced with a standing flat roof in 1964. It is a waterproofing layer made of regular felt stacked above the solid. 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. Then a 2 4 outlooker is placed over the dropped gable and butted into the side of the adjacent full height truss.

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. 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. If a truss roof is used with this method the gable truss is manufactured 3 shorter than the others. In wood frame construction the primary structural members of a gabled roof frame are the ridge board and the rafters.

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. A composite decking made of solid materials it resembles real wood and particularly strong and stable for bearing heavy load.
