What pushes a quote up
| Cost driver | Published price | Source |
|---|---|---|
| Tear-off, single layer | $1.00 to $2.50 per sq ft | RoofVista |
| Tear-off and disposal | $1 to $2 per sq ft | All American |
| Dumpster | $500 to $800 | RoofVista |
| Replacing rotted decking | $2.75 to $5.00 per sq ft | RoofVista |

The size of the roof matters most. Cigna Roofing says the average Long Island home has 15 to 30 squares of roof. A steep roof, lots of valleys and dormers, or two layers to tear off all push the price toward the top of the range.
Using these numbers
These ranges come from roofers marketing their own work, so treat them as a guide to where a fair quote lands, not a price. The only way to know your number is to have two or three roofers measure the roof. When the quotes come in, compare them line by line using the checklist on our roof replacement page.
