Houston firefighters fought the flames at a home on Gnarled Chestnut Court near Vermont Green Trail at about 11:15 a.m.

The firefighters were injured when a roof partially collapsed, investigators said.
"We understand there was some partial collapse inside the building. And at that time, the complication may have separated the mask from one of the firefighters," assistant chief Rick Flanagan said.
All three were taken to Memorial Hermann Hospital for treatment.
Brandon Everett, 26, was in stable but critical condition with smoke inhalation.
Abdias Dorville, 37, and David Lee, 45, suffered first- and second-degree burns on their arms and hands. They were listed in good condition.
"Two of those firefighters are fine. They are alert. They are conscious," Flanagan said.
Lee might be released from the hospital Monday night.
Neighbors said they heard a loud boom before the home's garage went up in flames. The fire then spread to the house.
Homeowner Greg Deleon said he rushed to get his wife and daughter out when he spotted smoke.
Deleon said he believes his two dogs in the garage caused the fire when they knocked over the space heater.
Fire officials did not confirm that as the cause, however.
"They all got out in time. The wife's pregnant but she's all right. They're OK right now," neighbor Yolanda Herrera said.
The family's BMW was destroyed.
The cause of the fire is under investigation.
