I have a small cement block house, approx 20 X 32. The roofing system/ceiling is stick-built with 2X4 locust. There exists neither electrical wiring (old house) nor equipment in the attic. Some kicker supports are ran from the rafters to the joists in a few places.

Is it possible to remove the ceiling, joists and center, currently supporting, wall, making basically a one room structure, allowing the use of the rafters as an exposed-beam type ceiling? (to be boxed, insulated and finished) Or do I have to remove the roofing system and start over?

Please help with suggestions.

Thanks
