Three people, including an 84-year-old woman, were injured in the blast on Thursday morning in Clinton Township, Wayne County.
Officials believe a 100-pound propane cylinder outside the home ignited, causing an explosion that also set off two other propane tanks.
According to state police, the 84-year-old woman said she was in the kitchen when the blast happened.
She told investigators her 63-year-old son was upstairs and that she tried to get to him, but the debris on the stairwell made it impossible.
Her son eventually climbed out a window, got onto a roof, and jumped to safety.
The woman's husband was on the porch at the time and was able to get away.
All three were taken to the hospital for treatment.
