The Harris County Fire Marshal is investigating a house fire in Northwest Houston.

According to investigators, the blaze broke out around 11:30 p.m. Wednesday night in the garage of a home on Whispering Wood Lane near Golden Wood Lane. Firefighters said flames quickly spread into the attic and through the roof.

Crews got the fire under control shortly after arriving to the scene. According to the fire marshal, the homeowners had left an hour before the blaze broke out, so no one was home at the time. Officials said nobody was injured.

The cause of the fire is still under investigation.
