Roll-Off Dumpster
An open-top container designed to be delivered and picked up by a specialized truck, rather than a fixed-location bin serviced on a regular schedule. "Roll-off" refers to how traditional cable-and-rail trucks unload the container by rolling it off the truck bed — the term stuck even as hook trucks became common.
Why it matters: Worth knowing mainly so you're not confused when the container looks nothing like a standard trash bin — this is the term the industry uses, so it's what most listings, permits, and quotes refer to.
Hook Truck
A delivery truck that uses a hydraulic arm to lift a container directly off the truck bed, rather than the cable-and-rail system a traditional roll-off truck uses. Hook trucks generally need less swing room and place containers more precisely. See our FAQ for how this affects delivery to tighter driveways.
Why it matters: This matters most if your driveway is tight or your street has limited turning room — a hook truck's smaller footprint often makes delivery possible where a cable truck couldn't fit.
Cubic Yard
A unit of volume — 3 feet by 3 feet by 3 feet. Dumpster sizes are named by their approximate volume in cubic yards (a "20-yard dumpster" holds about 20 cubic yards), not by weight.
Why it matters: Two containers of the same cubic-yard size can hold very different actual weights depending on the material — this is why sizing by yardage alone isn't the whole story for dense debris like concrete or shingles.
C&D Debris
Shorthand for "construction and demolition" debris — the standard material generated by building, renovating, or tearing down a structure. Most of what's covered in our disposal guides falls under this category.
Why it matters: Knowing this term helps if you're researching disposal rules or facility requirements online — many transfer stations and recycling facilities use it specifically in their acceptance policies.
Weight Allowance
The amount of weight included in a container's base price before an additional per-pound charge applies. Weight allowance is why cubic yards alone don't tell the whole story — see our weight calculator to estimate this before booking.
Why it matters: This is the single number that most determines whether your final price matches your quote — worth confirming up front for any project involving concrete, dirt, or roofing debris.
Overage
The additional charge billed when a container's actual weight exceeds its included weight allowance, based on a certified weight ticket from the disposal facility.
Why it matters: This is the one line item that can genuinely surprise someone who assumed a flat price — knowing it exists ahead of time is the easiest way to avoid it.
Tonnage
Weight measured in tons (2,000 lbs each) rather than pounds — commonly used when discussing weight allowances and overage pricing for larger loads.
Why it matters: Useful to know when comparing your project's expected debris to a container's weight allowance, since allowances and overage rates are usually quoted in tons, not pounds.
Swap
Picking up a full container and dropping off an empty one in the same visit, rather than requiring a new reservation — common on larger projects generating more debris than one container can hold.
Why it matters: Worth asking about for any multi-week project — a scheduled swap is usually more practical, and often cheaper, than renting a second full container from scratch.
Tipping Fee
The fee a disposal facility (landfill or transfer station) charges to accept and process a load, based on weight and material type. This is a real cost baked into dumpster rental pricing, not an arbitrary markup.
Why it matters: This is baked into what you're quoted, not billed separately — knowing it exists explains why prices vary by material and by facility, not just by container size.
Transfer Station
A facility where waste is consolidated and sorted before being shipped to its final destination — a landfill, recycling facility, or specialized processor — rather than a landfill itself.
Why it matters: Worth knowing the difference from a landfill mainly for context — it doesn't change your rental experience, but it explains why waste doesn't go straight from your driveway to its final resting place.
Landfill
A regulated site where waste is permanently buried, used for material that can't be recycled, composted, or otherwise diverted. See our disposal guides for what can realistically be diverted before defaulting to landfill disposal.
Why it matters: Understanding what does and doesn't end up here is part of why our disposal guides walk through sell/donate/recycle options first — landfill space isn't infinite, and diverting what can be diverted is worth the extra step for some materials.
Certified Weight Ticket
An official record of a container's weight, generated at the disposal facility's scale both before and after unloading. This is how overage charges are calculated — not an estimate.
Why it matters: This is the actual documentation behind any overage charge — if a bill ever seems off, this ticket is the record that settles it.
Driveway Protection
Boards or plywood placed under a container to help prevent scratching, cracking, or staining a driveway surface during a rental. NorthPoint includes this as standard on every delivery — see our FAQ for details.
Why it matters: Worth confirming is standard before booking anywhere, since not every company includes it — a scratched or cracked driveway is one of the most common complaints in this industry when it's skipped.
Prohibited Materials
Items not accepted in a standard container regardless of project type — hazardous waste, certain electronics, and specific chemicals. See our full materials guide for the complete list.
Why it matters: Worth checking before you start loading, not after — removing a prohibited item from an already-loaded container is a lot more hassle than setting it aside from the start.
Hazardous Waste
Materials that pose a risk to health or the environment if disposed of improperly — paints and solvents, certain batteries, asbestos-containing material, and similar items. Never accepted in a standard dumpster.
Why it matters: The distinction matters because these items usually need a specific drop-off location — many transfer stations have a separate household hazardous waste collection day — not just a different container.
Debris Box
Another regional term for a roll-off dumpster, more common on the West Coast than in New England — functionally the same container.
Why it matters: Mostly useful if you're comparing quotes or reviews from companies outside New England — same container, different regional name.
Delivery Window
The scheduled timeframe (typically a range of hours, not an exact time) a container is expected to arrive on its delivery date, based on that day's overall route.
Why it matters: Worth asking for specifics if your schedule is tight — most companies, including us, can narrow a wide window down with a call closer to the date.
Dumpster Permit
A local permit sometimes required when a container needs to sit in a street, right-of-way, or other public space rather than private property. Requirements vary by town — see our NH permit guide for specifics.
Why it matters: Worth checking before your delivery date if there's any chance your driveway can't fit the container — this is the one situation where planning ahead genuinely saves a delay.

Common Questions
Do I need to know these terms before booking a dumpster?
No — this glossary exists as a reference, not a prerequisite. Our team can walk you through sizing and pricing in plain language without you needing to know any of these terms first.
Why do dumpster companies use industry jargon like "roll-off" and "tipping fee" instead of plain English?
Some of it is genuinely functional shorthand (roll-off, hook truck) that's faster to say than a full description. Other terms — tipping fee, weight allowance — matter because they directly affect pricing, so it's worth understanding what they mean even if you never use the words yourself.
What's the most important term on this page to actually understand before booking?
Weight allowance, by a wide margin — it's the single biggest factor in whether your final price matches your quote, especially for dense materials like concrete, dirt, or roofing shingles.
Is a transfer station the same thing as a landfill?
No — a transfer station consolidates and sorts waste before it's shipped elsewhere, while a landfill is where waste is actually, permanently buried. Not every load ends up at a landfill; some gets diverted to recycling or specialized processing at the transfer station stage.
Does NorthPoint use hook trucks or cable roll-off trucks?
Hook trucks — this generally means less swing room is needed for delivery and more precise container placement, which matters most on tighter driveways or lots.
What should I do if I don't understand a term used in my quote?
Ask — any of our locations can explain a term in plain language before you book. Nothing here is meant to be confusing on purpose; it's just industry shorthand that becomes familiar with a little context.
Are these terms used the same way by every dumpster company?
Mostly yes, though regional variations exist — "debris box" versus "roll-off dumpster" is one example. The underlying concepts (weight allowance, tipping fees, overage) are consistent across the industry even if the exact wording differs.
Where can I learn more about weight allowance and overage pricing specifically?
Our weight calculator walks through both in more detail, with real numbers you can apply to your own project.
