The roof collapsed at a vacant Nappa Auto Parts store at the corner of Main Street and Rider Avenue in Patchogue on Tuesday morning, according to Suffolk County police and Patchogue village officials.

The ceiling also collapsed at 30 Minute Photo on Fort Salonga Road in East Northport due to water leakage, taking down wires in the process, according to police.

Firefighters responded to the scene in both cases. There were no reported injuries in either collapse.

The incidents come after Smith Haven Mall in Lake Grove was forced to close at 4 p.m. Monday because water leaked into several stores. All but six stores reopened Tuesday afternoon.

A mall spokeswoman said reports that the mall’s roof partially collapsed are untrue. The Fire Marshall has been inspecting the mall.

Smithtown Bowl also suffered a partial roof collapse over the weekend.

Smith Haven Mall in Lake Grove closed its Lifestyle Wing, which includes Payless, Starbucks and Sephora before the rest of the mall was closed by the Fire Marshall at about 4 p.m., according to a spokeswoman for the Simon-operated mall. She also said local media reports of a partial collapse of the mall’s roof were not true.

New York & Co. suffered the worst water damage. It’s unclear what time the mall will reopen Tuesday.

Walt Whitman Mall in Huntington Station, which is also run by Indiana-based Simon, was partially evacuated as well after workers at a nearby construction site mistakenly ruptured a natural gas line, according to a Suffolk County police spokeswoman.
