How to Use This Calculator
Start on the Quick Estimate tab by entering your total roof area, the number of existing shingle layers, and the type of roofing material currently installed. The calculator instantly produces a tear-off cost range including labor, dumpster rental, and disposal fees. Asphalt is the cheapest to remove; tile and slate cost significantly more.

Switch to the Detailed Breakdown tab for a line-by-line cost analysis. Here you can factor in roof access difficulty, asbestos testing needs (important for pre-1980 homes), and dumpster sizing. The calculator estimates total debris weight, recommends the number and size of dumpsters, and calculates disposal fees based on your state. If asbestos abatement is needed, the cost impact is shown separately.

The DIY vs Pro tab helps you decide whether to tackle tear-off yourself. It compares your estimated time investment (based on helpers and roof complexity), the cost of renting a roofing shovel, safety harnesses, and a dumpster versus hiring a contractor who includes everything. For most homeowners, professional tear-off is worth the cost because it is faster, insured, and includes cleanup — but DIY on a single-story walkable roof can save $1,500-3,000.

The Formula
Debris Weight = Roof Area x Material Weight per sq ft x Number of Layers Asphalt: 2.5 lbs/sq ft/layer, Wood: 4 lbs/sq ft, Tile: 10 lbs/sq ft, Slate: 8 lbs/sq ft Dumpster Count = Debris Weight / Dumpster Weight Capacity 10-yard: 3,000 lbs, 20-yard: 4,000 lbs, 30-yard: 5,000 lbs, 40-yard: 6,000 lbs Tear-Off Labor = Roof Area x Labor Rate per sq ft x Access Multiplier Access Multiplier: Easy = 0.85, Standard = 1.0, Difficult = 1.30 Dumpster Cost = Count x Rental Rate ($300-600 per 20-yard) Disposal Fee = Debris Weight / 2,000 (tons) x Tipping Fee ($40-80/ton) Total Tear-Off = Labor + Dumpster Rental + Disposal + Asbestos Testing (if any)
Example Calculation
For a 2,000 sq ft roof with 2 layers of asphalt shingles, standard access:
• Debris weight: 2,000 x 2.5 x 2 = 10,000 lbs (5 tons)
• Dumpsters: 10,000 / 4,000 = 3 x 20-yard dumpsters (or 2 x 30-yard)
• Tear-off labor: 2,000 x $1.75 = $3,500
• Dumpster rental: 3 x $425 = $1,275
• Disposal: 5 tons x $55/ton = $275
• Total tear-off: $5,050 (range: $4,200-$6,000)
• Compare: Same roof single-layer = ~$2,800-$3,500

Frequently Asked Questions

How much does roof tear-off cost per square foot in 2026?
Asphalt shingle tear-off costs $1.00-1.75 per sq ft for a single layer and $1.50-2.50 per sq ft for two layers in 2026. This includes labor, dumpster rental, and disposal fees. Wood shake removal runs $1.50-3.00 per sq ft because shakes are nailed more densely and create bulkier debris. Tile and slate tear-off is the most expensive at $3.00-6.00 per sq ft due to the extreme weight (9-12 lbs/sq ft for tile vs 2-4 lbs for asphalt) and need for additional dumpsters or specialized equipment.
When is tear-off required vs. an overlay?
Tear-off is required when: (1) there are already 2 layers of shingles (building code maximum in most jurisdictions), (2) the existing roof deck needs inspection for rot or damage, (3) you are switching to a heavier material like tile or slate, (4) the existing shingles are severely curled or buckled making a flat overlay impossible, or (5) local code requires full tear-off for warranty or wind-resistance compliance (common in Florida and coastal areas). An overlay saves $1.00-2.00 per sq ft but hides deck problems and adds weight.
How long does a roof tear-off take?
A professional crew of 4-6 workers can tear off a typical 2,000 sq ft single-layer asphalt roof in 4-8 hours. Double layers add 3-4 hours. Tile or slate removal takes 1-2 full days for the same area because each piece must be removed individually and the debris is much heavier. DIY tear-off with 2-3 helpers typically takes 2-3 times longer — plan for a full weekend for an average roof, and have tarps ready in case you cannot finish before weather arrives.
What should I expect during a roof tear-off?
Expect significant noise from prying and hammering, debris falling into protective tarps below, and dust. The crew will deliver a dumpster the day before or morning of, set up ground-level tarps and plywood sheets to protect landscaping, and use roofing shovels or powered shingle removers to strip the roof in sections. Each section is cleared to the deck, inspected for damage, and covered with underlayment before end of day. Nails are swept with magnetic rollers both on the roof and around the property. Keep vehicles, pets, and children well away from the work zone.
Do I need a permit for roof tear-off?
In most US jurisdictions, a permit is required for any re-roofing project, which includes the tear-off phase. The permit cost is typically $150-500 and is usually bundled into the overall roofing permit — you do not pay a separate tear-off permit. Some municipalities require a separate demolition permit for tear-off of very heavy materials (tile, slate) or if asbestos is involved. Your roofing contractor typically pulls the permit as part of their scope, but confirm this before signing the contract.
