Tent the work area off with tarps. Keep in mind, that when you heat the underside of that steel roof….it WILL drip water everywhere you don’t want it. Spent almost 10 years in a metal Pole Barn…..1/2 had a concrete floor, half of that had a Game Room…..workshop (timeshared with the Barn’s owner) was the other 1/2 of the concrete floored area….one Kerosun Heater didn’t help a whole lot.

Harbor Freight sells a lot of large, CHEAP tarps…...staple them to the ceiling joists, and the walls. Tape the joints where the tarps overlap.
