A Wesley Chapel firefighter needed medical treatment while battling a Union County house fire Saturday morning. Crews say he was outside the house on Parkstone Drive when part of the roof fell on his legs. He didn't need to go to the hospital. The man who lives here says he woke up at 5:30 to the sound of hissing and realized the house was on fire. He, his girlfriend and her 9-year-old daughter got out safely along with two cats. He says he thinks a grill behind the house caught fire even though it was turned off hours earlier.
