If you called us and said nothing but "I need a dumpster," this is what we would send. The 20 yard is 22 feet long, 8 feet wide and 4.5 feet tall, holds about six to eight pickup loads, and includes 3–4 tons. It is the most-rented size in Janesville by a wide margin, and the reason is not just capacity — it is the wall height.
At 4.5 feet, a 20 yard is low enough that an adult can pitch a bag of shingles, a length of deck board or a bundle of drywall over the side rail. Compare that to a 30 or 40 yard, where the walls are six and eight feet and every single item has to be carried in through the swing door at ground level and then stacked. On a two-day tear-off or a weekend cleanout, that difference is measured in hours of labor and a whole lot of arguing. People who have rented a 30 for a job that wanted a 20 remember it.
The 20 is also the size that suits the widest range of real jobs around here: a full roof tear-off on an average Janesville ranch or two-story, a whole-home cleanout, a deck-and-fence removal, a kitchen-plus-bath remodel, an estate clearout with furniture and mattresses. Bulky-light debris is where it shines, because you can genuinely use all 20 yards before you approach the weight allowance.
Flat rate covers delivery, pickup, the weight allowance, disposal and tax — the number we quote is the number you pay. Seven-day standard rental. Driveway protection boards go under the rails on every drop. We load out of our yard at 103 S Grant Ave, so most Janesville deliveries are a short run. Call (608) 531-8367 and we will talk through your pile before you commit.
Right job, right box
What this size is built for
Ideal projects
- Full roof tear-off on an average Janesville ranch or two-story
- Whole-home cleanout of a three-bedroom house
- Estate cleanout with furniture, mattresses and boxed contents
- Deck and fence removal on a typical suburban lot
- Kitchen plus bathroom remodel run together
- Rental property turnover after a rough tenancy
- Garage demolition, wood frame, single or double
- Large yard and landscaping clearout with brush and old fencing
Pick a different size if…
- Concrete, brick, dirt or tile - book the 10 yard instead
- Two or three rooms of plaster-and-lath only - a 10 or 15 yard is cheaper
- A single small bathroom or one-room demo - the 10 yard is plenty
- Full gut remodels and additions with a crew - move up to a 30 yard
- Retail fit-out or warehouse cleanout in volume - see the 40 yard
Not sure? Call (608) 531-8367 and describe what you are looking at. We would rather sell you a smaller container than have you pay for space you do not use.
Capacity in real terms
How much actually fits
| What you're loading | How it fits in a 20 yard dumpster |
|---|---|
| Standard 33-gallon trash bags | roughly 110-130 when crushed down as you load |
| Roofing shingles (architectural) | about 30-35 squares of single-layer tear-off, garage included |
| Kitchen cabinets | two full kitchens of uppers and lowers with doors and drawers removed |
| Furniture from a 3-bedroom home | sofas, beds, dressers, dining set and mattresses, broken down |
| Deck lumber | a 16x20 deck including joists, railings and stair stringers |
| Drywall | roughly 3,500-4,000 sq ft of half-inch modern drywall, far less if it is plaster |
Low walls, throw-over loading, and why it matters
Container capacity gets all the attention and wall height gets almost none, which is backwards for anyone doing the work themselves. A 20 yard's 4.5-foot side is roughly chest height on most people. That means:
- You can throw over the side from ground level, from a wheelbarrow, or off a ladder for roof work.
- You are not walking a hundred round trips to the swing door and back.
- Two people can load from opposite sides at once without getting in each other's way.
- You can see into the container to judge how full it actually is, instead of guessing.
The comparison people wish they'd made
A 30 yard has the same 22-foot footprint but six-foot walls. A 40 yard is eight feet. Those extra yards are all vertical, and vertical capacity only helps you if you can get material up there. For a crew with a skid steer or a conveyor, fine. For a homeowner with a wheelbarrow and a Saturday, the extra height is a tax, not a benefit.
Where a 20's height still bites
Sheet goods and long lumber still need to go in through the door if you want them flat on the floor. Use the swing door for the first layer, then switch to over-the-side once the floor is built. Appliances and anything you should not be lifting to chest height also go through the door.
If your job genuinely needs more volume and you have equipment, look at the 30 yard. If it is heavy debris, the 10 yard is the right call instead.
Sizing a roof tear-off by squares and layers
Roofing is the job where guessing costs the most, because shingles are dense and the numbers add up fast. Roofers measure in squares — one square is 100 square feet of roof surface.
The working numbers
- Three-tab shingles: roughly 200–250 lbs per square per layer.
- Architectural / dimensional shingles: roughly 350–450 lbs per square per layer.
- Add for underlayment, felt, ice-and-water and nails, plus any rotten decking you replace.
What that means for a 20 yard
With 3–4 tons included, a 20 yard comfortably handles a single-layer architectural tear-off up to roughly 30–35 squares, which covers most Janesville single-family homes including a garage. Go to two layers and you have effectively doubled the weight on the same roof — a 20-square roof with two layers behaves like a 40-square roof, and you should plan on a heavier allowance or a swap.
Count layers before you book
Lift a shingle at a rake edge or look at the drip edge thickness. Older Janesville homes frequently have two or even three layers because roofing over was standard practice for decades. Three layers of architectural on a 25-square roof will blow past any single container's weight allowance and is genuinely a two-box job.
Loading tips for tear-off
- Set the container tight to the eave, on protection boards, and tarp what you cannot hit.
- Load evenly front to back; shingles bunched at the door end make the container ride badly.
- Keep the load level with the top rail — an overfilled box cannot be legally transported.

Whole-home cleanouts: a realistic plan
The 20 yard is the default for emptying a house — a downsize, a rental turnover, an estate. A typical three-bedroom Janesville home, cleared of everything the family is not keeping, lands inside a 20 yard about eight times out of ten.
A weekend that actually works
- Friday: container is delivered and positioned door-end toward the garage or the closest exterior door. Walk the house and put a colored sticker on anything staying.
- Saturday morning: work top down — attic, then bedrooms, then main floor. Bag small material as you go; do not carry loose items.
- Saturday afternoon: break down furniture. Drawers out of dressers, legs off tables, cushions separated, bed frames disassembled. This roughly doubles what fits.
- Sunday: basement and garage last, because that is where the dense material lives and you want it distributed over an already-built floor of light debris.
Keep out of the container
Paint, stains, solvents, motor oil, fuel, propane tanks, car batteries, tires, electronics and anything with refrigerant. Fridges, freezers, window ACs and dehumidifiers need the refrigerant recovered by a technician first.
Weight watch
Books, paper files, exercise equipment and waterlogged basement contents are the sleepers — a wall of boxed books can add a ton on its own. Spread them, do not stack them all in one corner.
See our estate cleanout service and the weekend plan for a full checklist.
Fit, access and placement for a 22-foot container
The 20 yard is 22 feet long, which is the point where Janesville's older streets start to push back. Newer east-side subdivisions off Wright Road and out toward Milton Avenue almost always work fine — wide drives, no mature canopy, clean approach. The pre-1940 west side and the neighborhoods near downtown are where you want to check first.
The measurements that decide it
- About 60 feet of straight approach. The truck backs in, tilts the bed and rolls the container off; it cannot do that around a curve.
- Roughly 23 feet of vertical clearance to raise the hoist. Overhead service drops to a detached garage are the single most common reason we cannot place a container where someone wanted it.
- 10–12 feet of width clear of cars, totes and trees.
- Firm ground. Asphalt, concrete or compacted gravel, not turf.
Freeze-thaw
March and April are the risky weeks. As frost leaves the ground, driveways that hold a loaded container all summer will rut in spring. If you are working in that window, tell us and we will look hard at placement.
If it won't fit
Two options. Step down to the 15 yard at 16 feet, which solves a lot of short-driveway problems. Or ask about street placement, which may require a permit from the City of Janesville depending on where you are.
Outside town? We run to Beloit, Evansville and across the whole service area.

Answers
20 Yard Dumpster — frequently asked questions
Why is the 20 yard the most popular size in Janesville?
Two reasons. It matches the volume of the most common local jobs, a full roof tear-off or a whole-home cleanout, and its 4.5-foot walls let you throw debris over the side instead of walking every piece in through the door. That second point is why people who rented a 30 yard for a 20 yard job usually do not do it twice. Call (608) 531-8367 and we will confirm it suits your project.
Will a 20 yard hold my whole roof tear-off?
For a single layer of architectural shingles, a 20 yard handles roughly 30 to 35 squares, which covers most Janesville single-family homes plus the garage. Layers are what change the math. Two layers on a 20-square roof weighs about the same as a single layer on 40 squares. Lift a shingle at the rake edge and count before you book, because older homes here often have two or three layers.
How much space do you need to deliver it?
The container is 22 feet long and 8 feet wide, and the truck needs about 60 feet of straight approach plus roughly 23 feet of vertical clearance to raise the hoist. That overhead figure catches people out; it is the truck's arm, not the box. Low service drops, cable lines and mature boulevard trees are the usual blockers on older Janesville streets. Send a photo of the driveway and we will tell you before delivery day.
Can I fill it right to the top?
Level with the top rail, yes. Above it, no. An overfilled container cannot legally be tarped and transported, so our driver will not be able to take it until you level the load, and that costs you a trip and a delay. If you are getting close and still have material, call us. Swapping for an empty container is straightforward and usually cheaper than the hassle of a failed pickup.
What if my debris is heavy rather than bulky?
Then the 20 yard is probably the wrong box. Concrete, brick, dirt, tile and old plaster-and-lath hit the weight limit long before they fill the space, so you would be paying for 20 yards of air. A 10 yard is our dedicated heavy container for exactly that reason. If you have a mix of heavy and general debris, the usual answer is two containers rather than one compromise.
