Before ordering: Tell the rental company the roof area, shingle type, number of layers, and whether felt, flashing, wood, or other debris will be mixed in.

How to use the result

Call the rental company with the weight estimate—not only the dumpster size.

A container can have enough physical space but an insufficient included-weight allowance. Tell the provider that the load contains roofing shingles and confirm which mixed materials are accepted.

This calculator provides a planning range, not a guaranteed scale-ticket weight. Product thickness, moisture, extra layers, attached material, and packing change the final load.
