Thank you very much for your response. I agree with the incompentance on all parts of the work done and inspection conducted as well. This facility was built back in 1970s and handed over to us so very little we could have done.

The roofing detail was not done well, as it is evident with this problem.

The white service mast is for the communications service, which is not much of an issue, but the painted (brown) electrial service mast which penetrates the roof is an issue.
