A transportable insulated blanket roller has a support, and a riser coupled to and extending vertically from the support. A bearing support is coupled to the riser, and has an insulated blanket retaining rod passing through the bearing support. The rod has a bifurcation defining first and second insulated blanket holding rods that are operative to receive an insulated blanket therebetween. A crank produces a rotary motion in the retaining rod, in turn winding the blanket onto the blanket holding rods. The transportable insulated blanket roller is combined with a land vehicle having a trailer hitch receiver or comparable coupling or support, and an insulated blanket. A method of efficiently using the transportable insulated blanket roller at a construction site is also presented, including using the bifurcated roller to roll an unrolled insulated blanket, and then sliding the insulated blanket off of the bifurcated roller.
