Louisiana Residential Roofing (7-803) Practice Test

On a pitched roof, two roof planes meet along the ridge. The outside angle created by that intersection is described as the external angle. This name fits because it identifies the angle visible on the exterior of the roof at the ridge, as opposed to the inside angle seen from the attic. The term hip refers to the external edge where two planes meet along a roof corner, not the ridge itself, and internal support structures or gutters aren’t describing this angle.
