Keep your cans out on jobs, and keep the contractors who rent them ordering from you.

The usual rental is booked days or weeks ahead: a bathroom gut with a set start date, a move, an estate cleanout after a closing, a roof scheduled for next Tuesday. The homeowner searches by size or by project, compares what each company includes (rental days, the weight allowance, what happens if the load runs over) and books whoever confirms a date and a clear price. Few rentals involve a site visit. The quote happens on the phone or a booking form, so the questions that decide the size (what is going in, how heavy it is, where the container will sit) have to be asked by whoever answers. Then come the urgent calls: a roofing crew whose box filled halfway through a tear-off, a flooded basement, a yard full of storm limbs, a landlord with an eviction cleanout due before the next tenant moves in. Those callers tend to book the first company that picks up and can commit to a time.

The steady volume comes from other trades. Roofers, remodelers, restoration companies, builders and junk haulers without their own containers order again and again, usually to job-site addresses. When the cleanup follows a fire, flood or storm, the homeowner's roofer or restoration contractor often places the order and the cost may become part of an insurance claim, so the invoice needs the address, the drop and pull dates and the weight tickets in a form an adjuster can follow. National booking sites compete for the same searches and hand the order to a local hauler. One of them, Dumpsters.com, says on its hauler partner page that joining is free, that partners get confirmed orders rather than leads, that it pays the hauler when the job is complete, and that it handles "every aspect of the customer relationship, from order placement to invoicing." Those orders can keep idle cans moving with no lead fee. The customer relationship stays with the broker, though, so a repeat rental may well start on the broker's site again.

Demand follows building and cleanup, and the calendar changes with climate. Where winters are mild, building and remodeling keep demand fairly steady through the year. On the Gulf and Atlantic coasts, a storm during the Atlantic hurricane season (June 1 to November 30, per NOAA) can put roofers and restoration crews on many addresses at once, and every one of them wants a container. In northern states, spring brings cleanouts and the first roofing jobs, and winter slows outdoor work and leaves snow and ice where you drop.
