Short answer
Roll off quotes include a weight allowance, commonly 1 to 2 tons on a 10 yard and 2 to 4 tons on a 20 yard. Material above that is billed at the local disposal rate, typically $50 to $125 per ton. Plaster, tile, concrete, shingles and wet carpet are the usual culprits.
Key numbers at a glance
| Item | Figure | Notes |
|---|---|---|
| 10 yard allowance | 1 to 2 tons | Varies by provider |
| 20 yard allowance | 2 to 4 tons | The most common size |
| 30 yard allowance | 3 to 5 tons | Light debris expected |
| Typical overage rate | $50 to $125 per ton | Tracks the local landfill rate |
| Concrete or damp soil | About 1 ton per cubic yard | Needs a heavy debris container |
| Asphalt shingles | About 250 lb per square | Per 100 sq ft layer |
Why is there a weight limit at all?
Because the truck has one. A roll off truck carrying a loaded container has a legal gross vehicle weight, and the disposal facility charges the provider by the ton.
Your quote therefore has two components bundled into one number: the service, which is fixed, and the disposal, which is not. The tonnage allowance is where the provider draws the line between them.
How is the tonnage measured?
At the scale. The truck is weighed on arrival at the disposal facility and again empty, and the difference is your load. That weigh ticket is the document behind any overage charge, and you can usually ask to see it.
This is why “it looked about half full” is not a defence. Volume and weight are different measurements, and only one of them is being billed.
Which materials cause the problem?
In order of density: concrete, brick, block, soil and asphalt, all around a ton per cubic yard. Then ceramic tile and plaster, which are far heavier than the modern drywall people mentally substitute for them. Then roofing shingles at roughly 250 pounds per 100 square foot layer.
Water is the quiet one. Saturated carpet, drywall and yard waste can gain a third of their weight again in a wet week, which is why a tarp over an open container is worth the trouble.
How do you stay inside the allowance?
Describe the material honestly when you book. A provider told “bathroom gut, including the tile floor” will quote a different allowance than one told “general remodel debris”, and the first quote is the one that will not surprise you.
Then separate. Dense material in a heavy debris 10 yard, general debris in a larger container. Two correctly sized containers reliably cost less than one surcharged load.
What if you are already over?
Call the provider before collection rather than after. Sometimes material can be moved into a second container, or a heavier allowance applied retrospectively at a better rate than the standard overage.
What does not work is loading above the top rail to fit it all in. A heaped container cannot be tarped for transport, so the driver either levels it at your cost or leaves without it.

Questions
How much does going over the weight limit cost?
Typically $50 to $125 per extra ton, depending on the local landfill rate. Ask for that figure when you get the quote, not afterwards.
How do they know what my load weighs?
The truck is weighed at the disposal facility, loaded and empty. The difference is your tonnage, and the weigh ticket is the basis for any overage charge.
Which materials are heaviest?
Concrete, brick, soil and asphalt at roughly a ton per cubic yard. Then plaster, ceramic tile, roofing shingles and water logged carpet or drywall.
Can I avoid overage by not filling the container?
Yes, and with dense material that is exactly the right approach. A heavy debris container is often filled only to a marked line partway up the wall.
Does rain add weight?
Significantly, to anything absorbent. Drywall, cardboard, carpet and yard waste all gain weight in rain. Keep a tarp over the container if the forecast is wet.
Is the allowance negotiable?
The included tonnage sometimes is, especially if you describe the material accurately up front. A higher allowance quoted at booking costs less than overage billed afterwards.
