This is a rough estimate. Actual weight depends on shingle manufacturer, moisture, underlayment, flashing, and nails. Steeper roofs have more surface area. When in doubt, size up. Call (940) 945-5689 and we will help you pick the right dumpster.
Reference Data
Shingle Weight by Type
One “square” of roofing covers 100 square feet. These are industry-standard weight ranges from major manufacturers.
| Shingle Type | Avg Weight / Square | Typical Use |
|---|---|---|
| Three-Tab Asphalt | 230 – 250 lbs | Budget-friendly, older homes |
| Architectural Asphalt | 400 – 430 lbs | Most new construction, premium look |
| Slate | 800 – 1,000 lbs | High-end, historic properties |
Our 25 & 30 Yard Dumpsters
WillWay carries 20 yard and 30 yard roll-off dumpsters. Both sizes work for roofing tear-offs. The 20 yard includes 2 tons and the 30 yard includes 3 tons. Extra weight is billed at $95 per ton over the included amount.
$250 Roofing Surcharge
Roofing materials like shingles are extremely dense and heavy. A $250 surcharge applies per dumpster for roofing loads. This covers the additional disposal costs for heavy, single-material loads at the landfill.
Pitch Changes Everything
A steeper roof has more surface area than its footprint suggests. We use a standard 6/12 pitch to estimate, but steep roofs (8/12+) can add 20% or more to the total weight. When unsure, round up.
Multiple Layers = More Weight
Some older roofs have 2 or even 3 layers of shingles stacked on top of each other. Each layer multiplies the total weight. Double-layer roofs are common and can double your dumpster count.
