LINCOLN, Neb. (AP) — Lincoln school officials say hail and rain from a storm last week caused extensive damage to a middle school that’s under construction.

The May 9 storm punched fist-sized holes into 80,000 square feet of roofing at the future Moore Middle School. It received the most damage among schools in the Lincoln district.

Hail beat through the school’s roofing and insulation while rain poured through still-open windows.

Construction workers patched up some of the holes, but district officials said Tuesday the damaged roof will need to be replaced as it covers a third of the total space. Other schools in Lincoln received minor damage.

Officials say insurance will cover what they estimate to be a six-figure damage cost.
