fractures at opposing rafters (near ridge)
fractures at opposing rafters (near ridge)
(OP)
Hello. I have two rafters in a log cabin structure that are fractured near the ridge. The two affected rafters oppose each other. The rafters are not water-stained and fractures are not in areas of knots. The rafters span about 17 feet on a 12:12 pitch roof. The rafters are about 3 wide, 7 1/2 inches deep and spaced about 6 feet 5 inches apart. One exterior wall (in near alignment with rafters) has wood rot near its bottom where a deck was once erected (and inadequately flashed) adjacent to the exterior wall. Please see photos attached and let me know what you think caused the rafter cracks. Thanks.

it looks like the rafters moved overtime as they dont appear to be perfectly aligned, could this movement have caused the splitting at the ridge joint?
as previoulsy mentioned the rafters look small
