The worker was trapped on a third-story ledge of the building as the flames engulfed the interior behind him, the Houston Chronicle reported.
Workers in an adjacent building recorded video as the man saved by firefighters and some quick thinking of his own.
While he waited for the ladder truck to come nearer, it appeared as though the flames got too hot for him on the third level, so he dangled from the ledge and dropped down to another ledge on the second floor.
From there, the ladder truck was able to get close enough to pull the man away as portions of the third floor crumbled away above.
The Houston Fire Department said winds of 15 to 20 miles per hour whipped up what started off as a small flame.
"There was a report of a couple of guys working on the roof doing welding," said Houston Fire DepartmentDeputy Chief Greg Lewis. "When our units arrived, there was a small fire and construction workers were attempting to put it out. There was sustained wind of 15 to 20 miles an hour, and it was a wind-driven fire."
