The invention relates to the technical field of detection devices, in particular to a detection device for deformation of a roof of a roadway head-on to-be-supported area and a control method. The seven frame air cylinders extend, and the seven frame position switches send out signals that the frame air cylinders extend in place; the five swing cylinders respectively drive the five detection assemblies to swing to first positions, and the five swing position switches send out electric signals; the five double-head air cylinders drive hollow double-head pistons and detection rods to translate towards the rough surface of the roadway, detection contacts abut against the rough surface of the roadway and stop moving due to resistance, the hollow double-head pistons overcome the elastic force of springs and continue to translate, and all the five detection position switches send out electric signals; the five angle sensors collect data. According to the invention, multi-point detection can be realized through one-
