Roofing debris is heavier than most people expect. A dumpster can hit its weight limit long before it looks full. That is when surprise overage fees show up on your bill.
So, how much does a roofing tear-off weigh? For one layer of asphalt shingles, plan on about 230 to 400 pounds for every square (100 square feet of roof). This guide shows you how to find your roof’s total weight, pick the right dumpster size, and avoid extra fees.
How Much Does a Roofing Tear-Off Weigh Per Square?
Roofers measure a roof in squares. One square covers 100 square feet. Weight per square depends on the material.
| Roofing material | Typical weight per square (one layer) |
|---|---|
| Metal panels | About 150 lbs |
| 3-tab asphalt shingles | 230 to 250 lbs |
| Architectural (dimensional) shingles | 250 to 400 lbs |
| Cedar or wood shakes | About 350 lbs |
| Clay, concrete tile, or slate | About 900 lbs |
These numbers come from several roofing debris weight guides. Sources differ a little, so treat every number as an estimate. For 3-tab shingles, 230 to 250 pounds per square is a common figure.
Architectural shingles are thicker, so they weigh more. Premium designer shingles can weigh even more than the range above.
How Do You Estimate the Total Weight of a Tear-Off?
You only need two numbers: how many squares your roof has, and the weight per square. Multiply them.
For example, a 25-square roof with one layer of architectural shingles at about 350 pounds per square weighs roughly 8,750 pounds. That is about 4.4 tons, before any rotten wood decking is added.
Not sure how many squares you have? Ask your roofer. The estimate should list the total squares. You can also call Titan Dumpster Rental and we will help you size it. Or try our free calculator below, then confirm the result with your dumpster company.

What Makes a Roof Tear-Off Heavier?
The base number is only the start. Four things can push the weight up fast.
Extra Layers
Each layer of shingles adds its own weight. A two-layer roof roughly doubles the tear-off. Look at the roof edge near the gutter to count layers.
Wet Shingles
Water adds weight. Rain-soaked shingles, felt paper, and wood can add 10 to 20 percent. If you can, schedule your dumpster delivery close to tear-off day, and keep the bin covered when rain is coming.
Underlayment, Nails, and Flashing
Your tear-off is not only shingles. It also includes felt paper, metal flashing, and thousands of nails. Any damaged wood decking you replace goes in the dumpster too.
Steep Roof Pitch
A steep roof has more surface area than the house footprint suggests. A common pitch multiplier shows that an 8/12 roof has about 20 percent more surface than a flat measurement. More surface means more shingles and more weight.
How Much Does a Bundle of Shingles Weigh?
Many homeowners search this when they plan a new roof or a repair. Bundle weights vary by brand and product line, but here are common ranges from Pro Craft Home Products:
- Architectural shingle bundle: 60 to 80 pounds
- 3-tab shingle bundle: 45 to 60 pounds
- GAF 3-tab bundle: 45 to 55 pounds
Three bundles usually cover one square. A full pallet holds about 42 bundles, which covers about 14 squares. An architectural pallet weighs about 2,520 to 3,360 pounds. A 3-tab pallet weighs about 1,890 to 2,520 pounds.
For brands like Owens Corning, check the label on the bundle or the maker’s product sheet. Weights change by product line.
What Size Dumpster Do You Need for a Roof Tear-Off?
For roofing, weight matters more than size. A bin of shingles can reach its weight limit while it still looks half empty. Here is a simple starting point for one layer of shingles. Each size links to its page, so you can see the details:
| Roof size (one layer) | Common starting point | Learn more |
|---|---|---|
| Up to about 15 squares | 15-yard dumpster | 15-yard details |
| About 15 to 30 squares | 20-yard dumpster | 20-yard details |
| About 30 to 45 squares, or two layers | 30-yard dumpster or two 20-yard hauls | 30-yard details |
Weight limits depend on the company. Many include roughly 1 to 4 tons depending on dumpster size, and extra weight is billed on top. Overage fees often run about $50 to $100 per ton. Small roofs, like a shed or garage, can fit a 10-yard dumpster.
Very heavy roofs, such as slate or tile, often need more than one dumpster. A 40-yard bin full of shingles can also be too heavy for a truck to haul safely. If your tear-off is large, plan for a swap instead of one oversized bin. For dense debris like tile, brick, or concrete, see our concrete and heavy debris dumpster rental.
How Do You Avoid Overage Fees on a Roofing Job?
Follow these simple steps:
- Count your squares and your layers before you call.
- Tell the dumpster company the shingle type and whether you will replace decking.
- Ask how many tons are included, and what extra weight costs per ton.
- Load only roofing debris. Household junk eats into your weight allowance.
- Load evenly, and do not fill above the top edge.
- Put boards under the bin edges and tarp nearby plants to protect your driveway and yard.
- Keep rain off the load when you can.
Actionable Takeaways
- Find your roof’s total squares from your roofer’s estimate.
- Multiply squares by weight per square (about 230 to 400 pounds for one asphalt layer).
- Add 10 to 20 percent for wet shingles, nails, and underlayment.
- Double the number for a second layer.
- Match the total tons to a dumpster size, then confirm the included tons with your provider.
- Book delivery close to tear-off day.
Conclusion
A roofing tear-off usually weighs 230 to 400 pounds per square for one layer of asphalt shingles. Extra layers, wet shingles, steep pitch, and decking all push that number higher. The best way to avoid surprise fees is to know your squares before you book and ask about included tons.
