A roll-off is an open top dumpster characterized by a rectangular footprint, utilizing wheels to facilitate rolling the dumpster in place. The open top container is designed to be transported by special roll-off trucks. Roll-offs are commonly used to contain loads of construction and demolition waste or other waste types.
The construction debris may originate from a building site where something is being built, renovated, or demolished. Roll-off dumpsters are also used for various clean-out jobs that need much material to be taken away. The material in the roll-off may be taken to a landfill, recycled, or disposed/recovered in some other way.
