Investigators suspect that Sunday's storm weather triggered at least two house fires.
In Mansfield, the roof collapsed after lightning struck a home on Poppy Drive. No one was injured.
Mansfield's fire chief said lightning hit about four homes in the town that spans Tarrant and Johnson counties.
Lightning also struck a home in the Trophy Club area Sunday morning. It hit the chimney and caused a fire in the attic.
Three rooms were destroyed, but no injuries were reported.
