A three-alarm fire ripped across the roof of Lewisville High School's Killough campus yesterday, triggering a massive response from area fire crews and keeping firefighters on scene into the early hours today. The school was empty at the time; no injuries were reported, and firefighters had to cut into the roof to chase stubborn hot spots. Neighbors said they saw thick, black smoke rising as fire units poured into the area.

Emergency crews were dispatched to the Killough campus at about 9:30 p.m. after a neighbor called 911 to report black smoke, according to FOX4. Lewisville Fire Department personnel found an active fire burning on the school's roof and upgraded the call to a three-alarm response as more trucks and equipment arrived.

How crews fought the blaze

Per the Lewisville Fire Department, firefighters cut multiple ventilation holes through a thick layer of roofing material to vent trapped smoke and reach hidden hot spots. Crews mounted a defensive rooftop attack to keep flames from punching into classrooms and hallways, then stayed on scene for hours working overhaul and mop-up.

Damage, investigation and safety

The fire was largely contained to the roof, crews prevented an interior breach and no injuries have been reported. The cause is still under investigation, FOX4 reported. Officials have not yet given a timetable for repairs or for when the campus will be inspected and cleared for use.

Context: Planned work and the campus

Killough was already on the district's maintenance radar earlier this year, when Lewisville ISD folded a major renovation and roof work for the campus into a larger capital package, as detailed in Hoodline. The Killough campus page on Lewisville ISD's site lists the school at 1301 Summit Ave., the address where crews responded last night.

City and district officials are expected to release more information as investigators work to pinpoint where and how the fire started. Anyone with eyewitness video or information from Tuesday night has been asked to contact the Lewisville Fire Department through the city's official channels.
