Roofing jobs generate a heavy, dense stream of debris — old shingles, underlayment, nails, flashing and wood. Getting the dumpster size and placement right keeps a St. Catharines re-roof on schedule and helps you avoid weight overages. Here's how to plan a roofing dumpster rental in St. Catharines, Ontario.
Why roofing debris needs special planning
Asphalt shingles are far heavier than they look. A tear-off on an average St. Catharines home can produce several tonnes of material, and that weight adds up fast inside a container. Choosing a size that balances volume with weight allowance is the key decision for a roofing project.
Recommended dumpster sizes for St. Catharines roofing jobs
The right size depends on the roof's square footage and how many layers are coming off. A common approach is one mid-size container for a standard home, with a swap-out or second container for larger or multi-layer roofs.
- 15-yard — small roofs, sheds, garages and single-layer tear-offs.
- 20-yard — the most common choice for an average St. Catharines home re-roof (approx. 25–30 squares).
- 30-yard — larger homes, multi-layer tear-offs or commercial roofing.
- 40-yard — large commercial roofs, though weight limits may require multiple containers.
Weight and overage considerations
Because shingles are dense, roofing loads often approach weight limits before a container is visually full. Going over the included weight allowance can trigger overage fees. If you're tearing off multiple layers or heavy architectural shingles, mention it in your request so your matched provider can advise on weight allowance and container count.
Placement for roofing jobs in St. Catharines
Roofers usually want the dumpster close to the house for fast shingle disposal — often in the driveway or along the street. Driveway placement on private property usually needs no permit; street placement in St. Catharines may require a permit from the City of St. Catharines. Protect the driveway surface with boards and confirm clearance for the truck delivering and picking up the container.
What roofing materials are accepted
Asphalt and fiberglass shingles, underlayment, felt, drip edge, flashing, nails and damaged wood decking are commonly accepted. Confirm accepted materials with your assigned provider, especially if the roof includes specialty materials.
