Roof Replacement Cost Calculator
Estimate what a new roof might cost based on the roof area, material type, pitch, and how many stories the home has. Adjust the inputs to see your illustrative range update instantly.
Estimates use US customary units (square feet / roofing squares) and USD. 1 roofing square = 100 sq ft.

Request contractor quotesWhat drives roof replacement cost
The biggest cost factors are roof area (more squares means more material and labor), material choice (asphalt shingles are the budget-friendly baseline; metal and tile cost significantly more but last longer), pitch (steep roofs slow down crews and require safety gear), and stories (multi-story homes add scaffolding time and risk). A tear-off adds meaningful cost but is often the right call.
Choosing the right roofing material
- Asphalt 3-tab shingles: Lowest upfront cost, typically last 15–20 years. Less common in new installations today.
- Asphalt architectural (dimensional) shingles: The most popular choice. Better wind resistance and a richer look than 3-tab; typically 25–30-year lifespan.
- Metal roofing: Higher upfront cost but 40–70-year lifespan, excellent in snow or high-wind areas, and often more energy-efficient.
- Concrete or clay tile: Premium look, very long lifespan, but heavy — some homes require structural reinforcement to support tile.
How to use this calculator
- Enter your roof area in square feet (or convert from roofing squares).
- Choose the material you are considering.
- Select the number of stories and roof pitch.
- Toggle tear-off on if old shingles need to be removed.
- Select your state for an illustrative regional adjustment.
What's not included
This estimate covers standard replacement on a typical residential roof. It excludes deck repair or replacement (rotted sheathing), structural repairs, skylight installation or relocation, gutters, chimney or dormer flashing upgrades beyond normal, and any sales tax that may apply in your state. Always ask your contractor for a written, itemized quote that covers these potential extras.

Frequently asked questions
How much does it cost to replace a roof?
It depends on roof size, material, pitch, and local labor rates. Asphalt architectural shingles on a moderate-pitch single-story home are the most common mid-range scenario. Use the calculator above for an illustrative range tailored to your inputs, then confirm with local roofing contractor quotes.
What is a roofing square?
A roofing square equals 100 square feet of roof surface. Roofing materials and contractor bids are typically quoted per square. A 2,000 sq ft house often has 2,000–2,400 sq ft of actual roof surface depending on pitch and overhangs.
How much does a steep roof pitch add to the cost?
Steep and very-steep pitches require special safety equipment, slow down installation, and can require extra underlayment. Labor costs can increase 15–40% compared to a moderate-pitch roof. The calculator applies an illustrative surcharge per square for steep and very-steep pitches.
Should I tear off the old roof or re-roof over it?
Most building codes allow a maximum of two shingle layers. If you already have two layers, a full tear-off is required. Even with one existing layer, many roofers recommend tear-off so they can inspect the deck for rot or damage and start with a clean surface. The calculator adds tear-off labor and disposal cost when that toggle is on.
Are these prices verified?
No. All figures are illustrative planning estimates compiled for demonstration purposes, not verified current market pricing. Roofing costs vary significantly by region, season, and contractor. Always get multiple written quotes from licensed local roofing contractors before budgeting.
