What Size Dumpster Do I Need for a Roof Tear Off
What Size Dumpster Do I Need for a Roof Tear-Off?
For most single-layer asphalt shingle roofs, a 20-yard dumpster is the right call. But roofing debris is heavy, not bulky — weight, not space, is almost always what determines the size you actually need. Here’s how to size it correctly based on your roof’s square footage and how many layers of shingles are coming off.
Why Weight Matters More Than Size Here
Roofers measure roof area in “squares” — one square equals 100 square feet. A single square of asphalt shingles weighs 250 to 400 pounds depending on the type: standard 3-tab shingles run lighter, architectural (dimensional) shingles run heavier. That weight adds up fast. A dumpster that looks nowhere near full by volume can already be at its weight limit, which is why a 10-yard dumpster is often physically big enough for a large tear-off but almost never able to hold the weight without an overage charge.
Dumpster Size by Roof Size
These are general sizing guidelines for a single layer of standard asphalt shingles on a typical roof pitch. If you’re tearing off multiple layers, size up — see below.
Up to 15 Squares (1,500 sq ft)
Roughly 3,750–6,000 lbs of debris. A 10-yard dumpster usually covers this size, common on smaller homes or single-section re-roofs.
20–25 Squares (2,000–2,500 sq ft)
Roughly 5,000–10,000 lbs. This is the most common range for a full residential roof, and a 20-yard dumpster is the standard fit.
30 Squares (3,000 sq ft)
Roughly 7,500–12,000 lbs. Larger homes with more roof area typically need a 30-yard container to stay under the weight limit.
40+ Squares (4,000+ sq ft)
10,000–16,000+ lbs. Large or multi-section roofs may need a 40-yard dumpster, or two containers scheduled back to back.
Multiple Layers of Shingles Change the Math
If your roof already has one or two layers of old shingles underneath, tearing off all of them roughly doubles or triples the debris weight for the same square footage. A 1,500 sq ft roof with two layers of 3-tab shingles can weigh over 8,000 lbs total — enough to push what would normally be a 10-yard job into 20-yard territory. Tell us how many layers are coming off when you book so we can size the container correctly the first time, rather than dealing with an overage fee or a second delivery mid-project.
Other Factors That Add Weight
Steeper roof pitches use more material per square foot of footprint, which increases actual roof area beyond what the building’s footprint suggests. Valleys, dormers, and skylights also add complexity and extra material. Heavier roofing types — slate or tile in particular — weigh dramatically more than asphalt and often require a different sizing approach entirely, sometimes with sequential smaller loads rather than one large container.

Frequently Asked Questions
What size dumpster do I need for an average house roof?
Most single-family homes have a roof in the 20–25 square range with one layer of asphalt shingles, which typically fits a 20-yard dumpster. Get the exact square footage and layer count from your roofer before booking to confirm.
How much does a square of shingles weigh?
One square (100 sq ft) of asphalt shingles weighs 250 to 400 lbs depending on whether they’re standard 3-tab or heavier architectural shingles.
Do I need a bigger dumpster if there are multiple layers of old shingles?
Yes. Each additional layer of shingles roughly adds the same weight again for the same roof area, so a job that would fit a 10-yard dumpster with one layer may need a 20-yard with two layers. Tell us your layer count when you book.
What happens if my roofing debris goes over the weight limit?
You’ll be charged a per-ton overage fee, typically $50–$100 per ton industry-wide. Giving us accurate roof size and layer information upfront is the best way to avoid this and get the right container the first time.
