Estimate the removal portion of a reroof using actual roof surface area, existing material, number of layers and a separate disposal allowance. See the result per roofing square so contractor quotes are easier to compare.
These are broad U.S. planning ranges. Pitch, stories, access, site protection, fastening, multiple layers and local dump fees can move a real bid outside them.
Use roof surface area, not house living area. If you already have a written disposal or dumpster allowance, enter it separately.
Roofers often discuss removal in roofing squares, where one square equals 100 square feet of roof surface. A published removal range of $1–$3 per square foot is equivalent to about $100–$300 per square before project-specific extras. Heavier systems such as tile or slate can be higher.
| Existing material | Broad removal reference | Equivalent per roofing square |
|---|---|---|
| Asphalt shingles / metal | $1–$3 / sq ft | $100–$300 / square |
| Tile / slate | $2–$5+ / sq ft | $200–$500+ / square |
Extra layers increase labor, fastener removal, debris weight and disposal. The calculator applies a planning factor for second and third layers so a one-layer quote is not compared directly with a multi-layer scope. A contractor may price extra layers differently, so replace this assumption with a written unit rate when you have one.
A 2,000 sq ft house is not automatically a 2,000 sq ft roof. Story count, garage area, overhangs and pitch change roof surface area. Use the Roof Pitch Calculator or Roofing Square Calculator if roof quantity is still uncertain.
For a 2,000 sq ft roof with one asphalt layer, the broad $1–$3 per sq ft reference equals about $2,000–$6,000 for removal before adding a separate disposal allowance. The wide range is intentional: this tool is designed to show what assumptions should be replaced with local written pricing.
Removal benchmarks are cross-checked against HomeGuide roofing material costs and HomeGuide roofing labor costs. Safety and scope questions should also be reviewed with a qualified roofing contractor.
A broad 2026 planning reference is about $100–$300 per roofing square for shingles or metal before project-specific factors, while heavier tile or slate removal can run higher. One roofing square equals 100 square feet.
A second layer increases labor and disposal, but there is no universal multiplier. This calculator uses a planning adjustment so the extra layer is visible; replace it with your contractor’s written additional-layer rate when available.
Sometimes. Quotes may bundle removal and disposal or list dumpsters and dump fees separately. The calculator keeps disposal visible so you can avoid counting it twice.
Use actual roof surface area. Living area can differ significantly from roof area because of pitch, garages, porches, overhangs and story count.
Often, but the scope varies. Verify the included number of layers, material type, disposal, site protection and how concealed decking repairs will be handled.
