Why roofing debris is different
Most household debris fills a dumpster by volume long before it reaches the weight limit. Roofing is the opposite: old shingles, underlayment and nails are dense, and a roof can hit the container’s weight allowance while the container still looks half empty. That is why the weight allowance in your quote matters more than the container size.
Step 1: know your roof in squares
Roofers measure roofs in squares. One square is 100 square feet of roof surface. A roof’s area is larger than the house’s footprint because of the slope and the overhangs, so ask your roofer for the number of squares on their estimate rather than guessing from the floor plan.
Step 2: estimate the weight
According to Dumpsters.com, asphalt shingles weigh roughly:
| Item | Weight | Source |
|---|---|---|
| 3-tab asphalt shingles | about 230–250 lb per square | Dumpsters.com |
| Architectural asphalt shingles | about 400–430 lb per square | Dumpsters.com |
Multiply by the number of squares and by the number of layers. Examples for shingles alone, before underlayment, nails and any damaged decking:
- 20 squares of 3-tab, one layer: about 2.3 to 2.5 tons.
- 25 squares of architectural shingles, one layer: about 5 to 5.4 tons.
- 25 squares, two layers (architectural over 3-tab): roughly 8 tons.
Industry sources commonly cite weight allowances of about 2 to 3 tons for a 10 yard container and 3 to 4 tons for a 20 yard container, but allowances differ by provider and region. Compare your estimate with the allowance in the quote.
Why layers matter – and when a full tear-off is required
Some roofs have been “recovered” – a new layer of shingles installed on top of the old one. Every extra layer adds weight to the tear-off. Building codes limit how far this can go: under the International Residential Code (section R908.3.1.1), a roof recover is not allowed where the existing roof already has two or more layers of any roof covering, where the existing roof is water-soaked or too deteriorated to serve as a base, or where it is slate, clay, cement or asbestos-cement tile. In those cases, the old roofing must be removed. Local codes are based on the IRC but may differ, and your roofer knows what applies.
So if your house already has two layers, plan for a full tear-off and a heavy load.
Step 3: pick the container
- Small roofs and one layer of 3-tab: a 10 yard container is often enough.
- Typical single-family roofs: a 10 to 20 yard container, sized by weight rather than volume.
- Large roofs, architectural shingles or two layers: expect more than one haul or a container with a high weight allowance.
- Tile, slate or concrete roofing: far heavier than shingles. Tell the provider – these often need small containers and several hauls.
Low, short containers are easier to load from a roof edge, and some providers offer containers specifically for roofing loads. Ask what they recommend.
Avoiding overage fees
- Give accurate numbers: squares, layers, shingle type, and whether decking will be replaced.
- Keep the load clean: some providers price a load of only shingles differently from mixed debris, and some recycle clean asphalt shingles. Ask before adding other junk.
- Load evenly and not above the rim. Overloaded containers may not be hauled until leveled.
- Ask about the overage rate: in Houston, for example, Angi lists $100 to $200 per ton above the limit.
A worked example
Say your roofer measures 28 squares. The house has one layer of architectural shingles over one old layer of 3-tab shingles, and a few sheets of decking will be replaced.
- Architectural layer: 28 × about 400–430 lb = roughly 11,200–12,000 lb.
- Old 3-tab layer: 28 × about 230–250 lb = roughly 6,400–7,000 lb.
- Together: about 17,600–19,000 lb, or roughly 9 to 9.5 tons – before underlayment, nails, flashing and decking.
That is far more than a standard container allowance. A provider would likely suggest two hauls or a container with a high weight rating, and possibly a smaller container so it is never overloaded. Knowing this before the tear-off day avoids an overweight container that can’t be picked up, or a surprise charge.
What else ends up in a roofing container
- Underlayment: felt or synthetic, light but bulky.
- Nails and flashing: small, but they add up; some roofers separate metal for recycling.
- Decking: damaged plywood or boards that are replaced. Ask your roofer how many sheets they expect to replace.
- Gutters: if they are replaced at the same time, they add volume, and aluminum can be recycled separately.
Shingle recycling
In some areas, clean loads of asphalt shingles can be recycled, for example into asphalt pavement. Whether that is possible depends on local facilities. If recycling is available, the provider may ask for a load with only shingles – no wood, trash or other roofing materials – and may price it differently. Ask when you book.
Placement and protection
A loaded roofing container is heavy enough to crack a driveway. Ask the provider about boards under the rails, keep the container away from septic tanks and drain lines, and make sure there is room for the truck to set it down and pick it up. Place it close to the roof edge to keep debris off the lawn, and cover landscaping with tarps.
Tear-off day checklist
- Confirm the container delivery for the day before or the morning of the tear-off.
- Move vehicles, and mark the spot where the container should go. Put boards under the rails if needed.
- Cover plants, air conditioning units and patio furniture near the roof edge with tarps.
- Remove fragile items from walls and shelves inside – tear-off vibrations can shake them loose.
- Keep children and pets away from the work area and the container.
- Check that the load is level and not above the rim before pickup, and schedule pickup as soon as the tear-off is done.
- Walk the yard with a magnet sweeper afterwards to collect stray nails.
Who orders the dumpster?
Many roofing contractors include a container in their price. Check the estimate. If the roofer does not include one, coordinate the delivery date with the tear-off day so the container isn’t sitting empty. If the work follows a storm, see our storm debris cleanup guide for how cities handle contractor debris.
How our service fits in
Local Dumpster Network is a free referral service. When you call, you are connected with an independent, local dumpster provider that serves your ZIP code. They recommend a container and confirm the price and weight allowance before delivery. More on roofing dumpsters.
