A north Tulsa home caught fire just before 1 a.m. this morning on North Boulder, south of 66th Street North.
Investigators aren't yet sure how the fire started but say there were heavy flames showing when they arrived on the scene.
Fire crews were able to get the fire out quickly, nevertheless.
Authorities said the house isn't a total loss, though there is a gaping hole in the roof right now.
No one was inside when the fire started.
