The unnamed man had to be airlifted to a nearby medical centre after reportedly tumbling off the roof of the Aerosmith frontman's five-storey house while working on restorations.

Sources tell Tmz.com the man was screaming in agony as he lay motionless on the ground.

Tyler is currently on tour in Asia with Aerosmith.
