Sizing a Dumpster for a Roof Tear-Off in Central Florida
Roofing is where sizing goes wrong most often, and it is always the same mistake: sizing by how the pile looks instead of what it weighs.
The one number that matters: squares
Roofers measure in squares. One square is 100 square feet of roof surface. A typical single-storey Central Florida home is somewhere between 20 and 35 squares depending on footprint and pitch; larger homes out toward Reunion, ChampionsGate and the estate sections of Celebration can run well past 50.
If you do not know your square count, your roofer does, and it is the first thing to ask. Everything downstream — container size, weight allowance, whether you need a swap — follows from it.
What a square of roofing weighs
This is the table that decides your container:
| Material | Approx. weight per square | Notes |
|---|---|---|
| Three-tab asphalt shingle | ~200–250 lb | Older, lighter product |
| Architectural asphalt shingle | ~250–400 lb | The current standard |
| Metal panel | ~50–150 lb | Light but very bulky |
| Concrete barrel tile | ~600–900 lb | Two to three times shingle |
| Clay barrel tile | ~600–1,000 lb | Heaviest common material |
| Underlayment and felt | ~15–30 lb | Adds up on a large roof |
| Roof decking (if replaced) | ~150–250 lb | Only if you are re-sheathing |
Run the arithmetic for a moment. A 28 square architectural shingle roof at 350 lb per square is roughly 9,800 pounds — just under five tons, before underlayment. That is already at or past the included allowance on a 20 yard.
Shingle sizing table
| Roof size | Single layer | Two layers |
|---|---|---|
| Up to 15 squares | 15 yard | 20 yard |
| 15–25 squares | 20 yard | 30 yard |
| 25–35 squares | 20 yard (watch weight) | 30 yard + swap |
| 35–50 squares | 30 yard | 30 yard + swap |
| Over 50 squares | 30 yard + swap | Multiple containers |
Note the wording on the 25–35 row. A 20 yard has the volume for that job comfortably. It is the weight allowance you need to watch, which is why we will quote the overage rate and often suggest the 30 for the top end of that band.
Why barrel tile changes everything
Concrete and clay barrel tile is extremely common across the 1990s and 2000s Central Florida housing stock — Celebration, ChampionsGate, Reunion, Hunters Creek, a great deal of the vacation home market. And it weighs two to three times what shingle weighs per square.
A 25 square tile roof can produce eight to eleven tons of material. Put that in a 20 yard and you are dramatically over what a roll-off truck can lawfully carry, with the container looking about half full.
Tile is also brittle and produces a lot of sharp fragments. Load it deliberately across the floor of the container rather than piling it at one end, both for weight distribution and because a container of loose tile shifts in transit.
The second layer problem
Florida allows a second layer of shingle over an existing roof in some circumstances, and plenty of homes in the older Kissimmee, St. Cloud and Buenaventura Lakes neighbourhoods have one. It roughly doubles the tear-off weight.
The trouble is that people often do not know until the crew is up there. Two practical steps: look at the rake edge from the ground, where a double layer is frequently visible as a thicker band, and ask your roofer to confirm during the inspection.
If it turns out on the day, call us. A swap-out mid-job is straightforward and far cheaper than an overloaded container that cannot be hauled.
Placement: where the container should actually sit
A tear-off crew that has to carry or barrow material an extra thirty feet loses real hours over a day. Placement is worth thinking about properly.
- Tight to the drip line on the elevation being torn off, so material can be dropped or chuted directly in.
- Doors facing the approach so ground crew can walk material in.
- Clear of the eaves overhead. The truck bed needs roughly twenty-two feet of vertical clearance to tip, so low eaves, power drops and trees dictate how close we can actually get.
- On boards. Non-negotiable on any driveway, and doubly so on pavers.
Tell us which elevation you are working on when you book and the driver will plan for it rather than defaulting to the middle of the driveway.
Decking, wet sheathing and the extras
Three things routinely add volume nobody budgeted for.
Rotten decking. Florida roofs that have leaked, particularly around valleys and penetrations, often need sheathing replaced. You will not know how much until the old material is off. Budget a little headroom.
Wet insulation. If there has been a long-term leak, saturated insulation in the attic may come out too. It is heavy and it is bulky.
Old flashing, vents and boots. Small individually, meaningful in aggregate on a complex roof.
And a practical note that is not about the container at all: a tear-off sheds an enormous quantity of nails. A magnet sweep of the driveway, lawn and street at the end of the job is twenty minutes well spent, and it is the single most common complaint homeowners have about roofing work.
Storm season and booking ahead
Central Florida roofing demand is seasonal in a way that matters for scheduling. After a named storm, roofing volume across Osceola County spikes and every hauler in the region is at capacity within days. Containers get scarce and lead times stretch.
If you are a roofing contractor, the single most useful thing you can do is set up a standing arrangement with a local hauler before the season rather than joining the queue on the Monday after landfall. We hold capacity for contractors who work with us regularly, and we are honest during those weeks about what we can and cannot deliver.
If you are a homeowner and your roof is nearing the end of its life, doing the work outside peak season is cheaper and faster in every respect — roofer availability, material lead times and container scheduling all improve.
