What Size Dumpster for Roof Shingles? (Squares, Layers, and Weight)

A roofing square is 100 square feet of roof. Layers multiply tons. Architectural vs 3-tab is hundreds of pounds per square. The stencil on the box is volume. The scale is the bill.

You do not size a roof dumpster by “always 20.” You size it by squares × layers × shingle type, then you ask what tons are actually included in that box.

Companies do not agree on the box. Dumpsters.com likes a 10-yard filled partway. Angi says 10 or 20, and warns that a too-large dumpster can blow the weight limit. Hometown maps 10 vs 20 by square footage, then jumps to 30- and 40-yard as the squares climb. Dumpsters On Demand (Nashville) is a volume outlier: they will talk about 35–40 squares in a 15-yard. Same pile. Different steel.

This page is the dedicated shingle-size URL. It is not a zip-code form, and it is not a reprint of the 10-vs-20 driveway fight. Where live pages disagree, the disagreement is the point. Every number below is that publisher’s, dated to the fetch, not an “industry standard” we averaged.

If you need the full 10/15/20/30/40 household chart, that is What size dumpster do I need?. If two quotes landed on a 10 and a 20 for reasons that are not a roof, that is 10-yard vs 20-yard.

How to count (do this, not a slogan)

1. Squares = roof square footage ÷ 100.

Dumpsters.com’s shingle-weight page: a square is 100 square feet of roofing material. Hometown’s shingle guide (updated January 19, 2023): same definition. Dumpsters On Demand: same. If the roof is 2,000 sq ft, that is 20 squares of one layer.

Measure the roof, not the footprint of the house. Pitch, hips, and overhangs add area. If you cannot get on it safely, use the tear-off bid. The bid already counted squares.

2. Multiply by layers.

Two layers is two roofs of debris on one footprint. Hometown: two layers doubles it. Dumpsters On Demand: a 25-square roof with two layers is 50 squares of material. Do not guess. Look at the edge, or ask the roofer what they will peel.

3. Ask the hauler what they use for lb/square for your shingle, and what tons are in that box.

Do not pick a blended number from the internet. Live pages do not agree:

Who (fetched Aug 30, 2026) What they publish per square
Dumpsters.com shingle-weight calculator 3-tab asphalt 230–250 lb; architectural 400–430 lb; slate 800–1,000 lb. They also say the exact weight depends on the manufacturer, and older shingles weigh less as they wear.
Hometown shingle guide (Jan 19, 2023) Typically 250–400 lb (3-tab vs architectural). Plus 50–100 lb per square for damaged plywood, felt, or other tear-off extras.
DumpsterBoard roofing guide Overall ~150–350 lb. Their split: ~230 lb 3-tab / ~350 lb architectural. Concrete/clay tile ~750–1,000 lb.
Dumpsters On Demand (Nashville) One square “around 250 pounds.”

Hundreds of pounds per square, on a 20-square roof, is tons. Architectural vs 3-tab is not a style note. It is the difference between a load that fits a 2-ton cap and a load that does not.

Dumpsters.com also says it typically takes three bundles to cover a square, and a bundle is about 33 square feet. Dumpsters On Demand says the same three-bundle rule for standard asphalt. Useful for translating a 10-yard “bundle” claim. Not a tape measure.

What companies actually say (not a blended chart)

These are live recommendations. They are not averaged. Read across a row, then notice the fight.

Source Their roofing box Their squares / area Their lb/square (theirs) What that implies
Dumpsters.com sizes FAQ 10-yard, fill partway. Same page: dense stuff (concrete, brick, dirt, or shingles) belongs in a 10-yard, only partway. Not a square chart on that FAQ. See their calculator row. The small box is the roofing tool because of weight, not because the roof is small.
Dumpsters.com weight calculator “Most common roofing dumpster is 10 cubic yards.” Architectural: 1 of those for <40 squares, 2 for 40–60, 3 for 60–80. 3-tab: 1 under 60 squares, 2 for 60–80. Calculator page: 3-tab 230–250; architectural 400–430. One 10-yard for 40 architectural squares is ~8 tons at their 400 lb figure. That only works if the box is a high-tonnage roofing / heavy-debris 10-yard, not a mixed-waste 10-yard with a 1–2 ton chart allowance.
Dumpsters.com shingle-weight FAQ (same site, different page) 10-yard “Approximately 10 to 15 squares of asphalt shingles, or 4 to 6 squares of slate.” Same 230–250 / 400–430 / 800–1,000 table. 10–15 asphalt squares in a 10-yard is a different answer than “one dumpster under 40 architectural.” Same company. Keep both.
Dumpsters.com 10-yard product page 10-yard “48 to 72 bundles of roofing shingles.” Using their 3-bundles-per-square rule, that is 16–24 squares. Not restated on this page. Average included weight on this page: 2–3 tons. Size chart elsewhere: 1–2 tons. Same page: a 10-yard can safely hold up to 10 tons. Three Dumpsters.com answers for how many squares fit a 10-yard: 10–15 (FAQ), 16–24 (bundles math on their numbers), and <40 architectural (weight-calculator table). The 10-ton figure is what they say the steel can carry, not what a mixed-waste quote includes.
Dumpsters.com sizes hub copy 20-yard “can accommodate … roofing jobs.” — — The FAQ on the same hub still says 10-yard for roofing, fill partway. Even the marketing page disagrees with the FAQ.
Angi, “What Size Dumpster Do I Need?” (updated Jul 9, 2026; live fetch) Roofing 10 or 20-yard. No square table. No lb/square. “Shingles are heavy, so filling up a too-large dumpster can put you over the weight limit. A smaller dumpster will prevent a load that’s too heavy to haul.”
Hometown ultimate guide (updated Nov 10, 2025) 10-yard / 20-yard 10-yard: about 1,500 sq ft single-layer. 20-yard: 2,500–3,000 sq ft single-layer. Not on this page. Typical allowance: 10-yard 2–3 tons; 20-yard 2–4 tons. Area-based, one layer. Two layers is a different job.
Hometown shingle guide (updated Jan 19, 2023, still live) 10 / 20 / 30 / 40, then two 30s Their 3-tab table: 15 squares → 10-yard; 20–25 → 20-yard; 30 → 30-yard; 40 → 40-yard; 50–60 → 2+ 30-yards. 250–400 lb. Average house 1,500–2,000 sq ft (15–20 squares) → 3,750–8,000 lb, roughly 2–4 tons, plus 50–100 lb/square extras. “A 10 yard dumpster is physically big enough to accommodate a large roof tear-off, but it rarely can accommodate the weight.”
DumpsterBoard roofing guide 10 or 20 for most houses; 30 for big or two-layer Most residential 1,500–3,000 sq ft, one layer → 10- or 20-yard. Their chart: 10-yard up to ~1,500 sq ft (~15 squares); 15-yard 1,500–2,500 (~25); 20-yard 2,500–4,000 (~35–40); 30-yard 4,000+ or two-layer (50+ squares). ~150–350 overall; ~230 / ~350 as their 3-tab / architectural. They also say most rentals include a 2-ton allowance, and a 2,000 sq ft two-layer architectural tear-off can generate 4–5 tons.
Dumpsters On Demand (Nashville) 15-yard as their “sweet spot”; 10-yard for smaller 15-yard “typically 35–40 squares” single layer; 10-yard around 25 squares. Later on the same page: 15-yard for jobs “around 2,500 square feet (or 25 squares)” and “around 3,600 pounds.” Their 10-yard shingles page: 10-yard for roofs under 1,500 sq ft (~15 squares) of single-layer 3-tab, “around 3,000 pounds.” “Around 250 pounds.” Volume outlier. 40 squares × their 250 lb = 10,000 lb / 5 tons. Hometown’s 3-tab table puts 40 squares on a 40-yard. Dumpsters.com’s architectural table would send two or three 10-yard roofing boxes for that many architectural squares. Same page also talks 25 squares in a 15-yard. They do not even agree with themselves. Shown, not picked.

The fight is not sloppiness. It is different constraints:

Do not pick a winner from the table. Ask the hauler which row they are living in.

Worked examples (labeled as theirs)

Arithmetic below uses only a named source’s numbers. It is not a blended calculator.

Hometown’s two-layer 15-square example (their math, Jan 19, 2023)

Hometown writes it out:

15 square × 250 lbs × 2 layers + 750 lbs = 8,250 lbs

They say that customer should rent a dumpster with at least a 5-ton weight allowance, preferably 6, to leave cushion against overage. 8,250 lb is a little over 4 tons of debris; the extra tons are the buffer.

Their 3-tab table, one layer, would have put those 15 squares in a 10-yard (3,750–6,000 lb). Two layers moved the problem from volume to tons. The house did not get bigger.

Hometown’s average house (same page)

They put an average home at 1,500–2,000 sq ft (15–20 squares), so 3,750–8,000 lb, roughly 2–4 tons, before the 50–100 lb/square of plywood and felt. A 20-square architectural roof at the top of their 250–400 band is 8,000 lb of shingles alone. Add extras and you are already looking at the high end of a typical 20-yard allowance on their November 2025 size guide (2–4 tons).

Dumpsters.com’s own three answers, on one 10-yard

Take a 10-yard of asphalt shingles, using only Dumpsters.com’s published figures:

At their architectural 400–430 lb/square, 15 squares is 6,000–6,450 lb (3–3.2 tons). Forty architectural squares is 16,000–17,200 lb (8–8.6 tons). Their size chart’s typical 10-yard allowance is 1–2 tons. Their 10-yard product page says average 2–3 tons, and a safe max of 10 tons. The table that allows 40 architectural squares in “one roofing dumpster” is only coherent if that dumpster is the high-tonnage version. The 1–2 ton mixed-waste 10-yard is a different SKU that shares a stencil.

Dumpsters On Demand’s 40 squares in a 15-yard (their numbers)

They say a 15-yard “can typically hold between 35 and 40 squares” of a single layer, and one square is “around 250 pounds.”

40 × 250 = 10,000 lb / 5 tons.

That 15-yard only works if its weight allowance is huge. Hometown’s 3-tab table would put 40 squares on a 40-yard (their estimated 10,000–16,000 lb). Dumpsters.com would send two or three 10-yard roofing boxes for that many architectural squares (40–60 → two; 60–80 → three).

On the same Dumpsters On Demand URL, they also say a 15-yard is for jobs around 2,500 sq ft (25 squares) and “around 3,600 pounds,” and that a 2,500 sq ft roof of 3-tab “can produce up to 5,000 pounds.” Those are three different 15-yard stories on one page. Shown. Not averaged. Not declared the Nashville truth for the rest of the country.

Angi, with no squares at all

Angi’s live article does not publish lb/square. It publishes a fork: roofing 10 or 20, because shingles are heavy and a too-large box can exceed the limit. That is the same lesson as Dumpsters.com’s “fill the 10-yard partway,” written from the other direction.

Why a 10-yard filled partway can beat a 20-yard with a 2-ton cap

Bigger is not safer when the debris is dense.

Dumpsters.com’s size FAQ is blunt: a 10-yard is their recommendation for roofing materials; fill it partway. You cannot put heavy materials in every size. Their weight calculator: most common roofing dumpster is 10 cubic yards. Their glossary: those bins are often small so the total weight stays within what the truck can lift.

Angi, live: filling a too-large dumpster can put you over the weight limit. The smaller dumpster is how you avoid a load the truck will not haul.

Hometown: a 10-yard has the volume for a large tear-off. It “rarely can accommodate the weight.”

Now look at included tons, which is the actual product:

A 20-yard whose quote includes 2 tons has less legal payload for shingles than a 10-yard whose quote includes 3 tons. The extra airspace in the 20 does not help. You hit the cap with daylight still showing, then you pay overage — or you get a load the driver will not take.

Dumpsters.com: going over the included limit is a pro-rated per-ton overage because landfills charge by the ton. Hometown’s shingle guide, still live as of this fetch, dated January 19, 2023: overage $50–$80 per ton typical, as high as $120 in some areas. That is Hometown’s 2023 claim, not a national tariff.

Practical read, not a slogan:

This is not the 14-foot vs 22-foot driveway argument. That lives on 10-yard vs 20-yard. This is weight wearing a volume costume.

Bagster: 800–1,000 sq ft of scrap, not a house

Waste Management’s Bagster is one size. Official FAQ, fetched August 30, 2026: 3 cubic yards / 606 gallons (not 3.3), 8 ft × 4 ft × 2 ft 6 in, 3,300 lb max.

WM’s product page and product-specs page list example fills under that 3,300 lb cap. One of them is 800–1,000 sq ft of roofing shingles (specs page: 30-year asphalt). That is 8–10 squares. It is a small, light, single-layer scrap job — a porch, a dormer, a leftover pile — not a house tear-off.

The heavy-debris rule is official, and it still applies:

The bag is not waterproof. Rain is extra weight against 3,300 lb.

If the pile is a real tear-off, the bag is the wrong product. The comparison of shelf price vs a 10-yard is Bagster vs dumpster. This page will not redo that math.

Felt, decking, wet loads, and mixing the pile

Shingles are not the whole dumpster.

Felt and decking. Hometown’s shingle guide: add 50–100 lb per square for damaged plywood, felt, or other tear-off extras. Their 15-square × 2-layer example baked in 750 lb of that. Dumpsters On Demand lists felt, underlayment, lumber, plywood, flashing, nails, and tar paper as typical roofing debris. Rotten decking is the sleeper. You will not know how much until it is off.

Wet loads. Dumpsters.com’s weight-calculator FAQ: actual weight varies with moisture, density, and how tightly the box is packed. Hometown’s 2023 overage warning is about tons hitting a scale. Bagster’s FAQ: the bag is not waterproof. Wet shingles are still shingles. They just cost more.

Clean load vs mixed. This is a rate problem, not a loading-style tip.

Dumpsters On Demand: tell the company you are throwing shingles. Some haulers want a “clean load” — only shingles, sometimes shingles and felt. Mixing in wood, flashing, gutters, or general trash can contaminate the load and change the fee. On their 10-yard shingles page, they also list lumber, plywood, flashing, and nails as acceptable in a roofing dumpster. Ask which rule applies to this quote. Do not assume.

Dumpsters.com’s glossary: a dedicated roofing dumpster keeps heavy asphalt out of a mixed load, and some facilities prefer that so shingles can go to recycling.

DumpsterBoard: ask about a shingles-only rate; they say many haulers offer flat-rate pricing for a clean shingle load. That is their claim, not a national menu.

A mixed C&D rate on a shingle-heavy box is how a “cheap” 20-yard becomes an expensive 20-yard. Cabinets, household junk, and a fridge do not belong in a shingle-only price.

Older roofs. DumpsterBoard: homes built before 1980 may have asbestos in older asphalt shingles, felt, or cement tile, and that does not go in a standard dumpster. Dumpsters.com’s roofing-dumpster page: most shingles are not hazardous, but asbestos needs an approved facility. Neither is a lab result. If the house is old enough to worry you, ask before the tear-off, not after the box is full.

What to ask the hauler

Get this in the quote. In writing if you can. None of it is a zip form.

  1. Included tons for this debris in this box. Not “the 20-yard.” Shingles-only vs mixed C&D can be different caps. Dumpsters.com’s own 10-yard pages do not agree with each other (1–2 vs 2–3 vs a 10-ton safe max).
  2. What lb/square they assumed, and for which shingle (3-tab, architectural, tile, slate). If they will not say, they are guessing at the same table you already saw disagree.
  3. Layer count they assumed. One vs two is a double.
  4. Overage per ton. Pro-rated? Rounded up? Hometown shingle guide (Jan 19, 2023, still live): $50–$80 typical, as high as $120 — their dated claim. Dumpsters.com: pro-rated after the scale. Ask what here charges.
  5. Shingles-only / clean load vs mixed. What else can go in (felt, flashing, plywood, gutters) without changing the rate. What contaminates it.
  6. Swap / empty-and-return. Dumpsters.com’s answer if the 10-yard fills: swap, or order another. Ask what that costs here before you “save” on one box.
  7. The actual box they will drop. Yard number does not lock tons, and it does not lock length. Ask L × W × H and the weight allowance on the contract, not the blog chart.
  8. Whether this market treats shingles as heavy. Matters for Bagster’s 1-yard cap. Matters for whether they will even put shingles in a 20- or 30-yard.
  9. Rental days and extra-day rate. Roofing crews are often done in a few days; weather is why you still ask.
  10. Prohibited list for this landfill. Paint, batteries, asbestos, mixed household trash. If a prohibited item is in the box, pickup can fail and still cost you.

If two haulers recommend different sizes, ask each what tons, what layers, and what shingle type they assumed. That usually ends the argument.
