A fellow inspector and I looked at a 50+ year old bungalow this morning with a significantly sagging roof (at the ridge and also along the plane of the roof). On inspection of the attic, we found that the ridge board was not continuous. It was made of twinned 1x4 cut to approximately 4 foot lengths. At either end of each four foot length, the rafters (2x4’s) were twinned and bolted together.
Has anyone seen this before? It was obviously done intentionally as the construction was very uniform.
