Roll off dumpster prices are determined by a number of factors. 1. Equipment Rental – Roll-off delivery trucks and dumpsters are not cheap! A brand new roll off dumpster delivery truck can cost over $100,000 and a new dumpster can cost over $10,000. 2. Fuel – All waste removal and dumpster rental companies are combating increasing diesel fuel costs. Hauling tons of waste burns lots of fuel.
