Roof Tear-Off Dumpster Guide: What Size, and Why Weight Decides It

Roofing is the job that breaks everybody's sizing instincts. People look at a big roof and order a big dumpster, then the load comes in half-full and overweight anyway. Here's the thing to understand: with shingles, you're not buying space. You're buying weight allowance.

Why Weight Runs Out Before Space

Torn-off shingles are one of the densest loads we haul.

A dumpster has two limits: its volume and its included weight allowance. Household junk hits the volume limit first. Shingles do the opposite: they stack dense and heavy, so the load reaches the weight allowance while the box still looks half empty. That's why renting a bigger container doesn't help a shingles-only job. The fix isn't more cubic yards, it's making sure the weight allowance matches the roof, which is a booking conversation, not a size upgrade. The full picture of how allowances and overage billing work is in the weight limits guide.

Picking the Size

Shingles only: 12-yard, usually. Shingles plus decking or framing: 15 or 20.

• Shingles-only tear-off: a 12-yard is usually more than enough space, and the conversation is really about the weight. This is the most common roofing setup we deliver.
• Tear-off plus old decking or framing: now volume matters too, because plywood and lumber are bulky. That's 15 or 20-yard territory.
• Full re-roof with new material packaging: wrappers, pallets, and cut-offs add volume fast on top of the tear-off. Go 20 if the whole job's debris is going in one box.

Two numbers make the sizing exact: your roof's square count (a square is 100 square feet; your roofer knows this number) and how many layers are coming off. A second layer roughly doubles the shingle weight, and it's the detail people forget to mention. Give us both and the size picks itself.

Placement for a Roofing Crew

Close to the roofline, clear overhead, boards if it's nice concrete.

Roofing crews want the dumpster tight to the house so debris goes straight from roof to box, by throw or by chute, usually on the driveway nearest the section being torn off. Book delivery for the day before the tear-off — routes run pickups earlier and deliveries later in the day, so a same-day delivery can land after the crew's already on the roof. Three things to square away before delivery day: confirm the spot with your crew, make sure there's clear space overhead with no low wires or branches (the truck lifts and tilts to place the container), and if it's sitting on nice concrete or blacktop, ask about our optional protective boards. More on all of that in the driveway guide.

Keeping the Overage Off the Bill

Be accurate about the roof, and plan for anything extra you toss in.

With us, overage past your included allowance bills at $150 per ton, prorated, after the load crosses the scale. On roofing jobs, the two ways it shows up: underestimating the roof (squares or layers), and adding other heavy project debris to the room left in the box. Both are fine — just plan for them. Shingles alone usually land near the allowance, so anything extra you load rides on top of that weight: count it in, expect the prorated overage on the heavy stuff, and there's no surprise when the scale ticket comes. Tell us at booking what else is going in and we'll size the box and the allowance to the whole job instead of just the roof.
