The state will conduct inspections of roofs at schools, designated disaster shelters and other state facilities following Friday’s roof collapse at the Farrington High auditorium, whose cause remains under investigation.

Officials said the 27-year-old roof at Farrington had had no reports of major problems.

Meanwhile, officials had no estimate for how much it would cost to make repairs to the building — described as the centerpiece of Farrington’s campus — and it remained unclear whether it could even be salvaged.

But Gov. Neil Abercrombie told reporters Monday the cleanup would be an “enormous undertaking,” and said the collapse would have surely been fatal had anyone been in the path of the debris.
