New built house – ridge tile blown off – ridge batten problem

[Omegassp]

Our house was newly built. In the 13th month, ridge tiles2 & 3 (together with the ridge unions) (photos A1, 2 & B) were blown off. We checked from the loft and found that the ridge batten was a bit weird. Some part (about ¼) seemed to be normal which is placed directly on top of the apex. But the rest seems to be of different material and is not placed directly on top of apex. It seemed to be attached to the side of the truss roof peak. (photo C) We could see the ridge roll (with some holes) along only one side (photo D). Besides, the ridge batten seemed to be not long enough. We did not see any batten directly under tiles 1 & 2 (may be 3 as well).

The builder’s roof contractor just replaced the missing tiles, and reinstalled tile 1. We wondered if the ridge unions could be firmly attached to the ridge batten if the batten was not directly on top of the apex. Yet, the contractor insisted that there was no further work required.

Is the ridge batten properly installed? Should the ridge batten be replaced if a number of the ridge tiles are displaced because the same point cannot be screwed in the second time? To save money, can we engage a roof surveyor just to check the ridge and recommend the repair work required?
