Roof replacement cost calculator

Build a realistic budget before you request quotes. We estimate roof area from your home, then adjust the installed range for material, stories, pitch, complexity, and tear-off.

This is a planning estimate. Hidden decking damage, code upgrades, specialty flashing, permits, access constraints, and contractor pricing can materially change a real quote.

Roof cost by house size

How much does roof replacement cost by home size?

These examples use a one-story home, standard roof pitch, moderate complexity, architectural asphalt shingles, and removal of one existing roofing layer. They are planning examples, not contractor quotes.

Finished home sizeEstimated roof areaPlanning range
1,000 sq ft1,230 sq ft$6,200–$11,700
1,500 sq ft1,850 sq ft$9,100–$17,300
2,000 sq ft2,460 sq ft$12,100–$22,800
2,500 sq ft3,080 sq ft$15,000–$28,400
3,000 sq ft3,700 sq ft$18,000–$33,900

Under these assumptions, the model places a 2,000 sq ft one-story home at roughly $12,100–$22,800. A two-story home with the same finished square footage can have a smaller roof footprint, while steep pitch, complex rooflines, and difficult access can increase labor cost.

Roof cost by material

Asphalt shingles vs. premium asphalt vs. metal roofing

Material choice is one of the largest cost drivers. The table below keeps the same 2,000 sq ft one-story example and changes only the new roofing material.

Roofing materialPlanning range
3-tab asphalt$10,800–$19,100
Architectural asphalt$12,100–$22,800
Premium / luxury asphalt$15,800–$27,800
Metal roofing$21,900–$40,100

Actual product lines can vary widely within each category. Flashing, ventilation, underlayment, warranty level, decking repair, permits, and local labor conditions can also change the final price.

What moves the number

Why two similar houses can get very different roofing bids

Roof size matters, but contractors also price labor difficulty and risk. A steep two-story roof with dormers, valleys, multiple penetrations, and two layers to remove is not the same job as a simple one-story gable.

  • Material: architectural asphalt is usually less expensive than premium asphalt or metal.
  • Pitch and access: steep and elevated roofs generally require more labor and safety setup.
  • Complexity: valleys, dormers, skylights, chimneys, and intersecting roof sections increase labor.
  • Tear-off: removing old roofing adds labor, disposal, and uncertainty about the decking underneath.
Questions worth asking

Before you accept a roofing quote

Why doesn't the calculator give one exact number?

A project cannot be priced precisely without an inspection. Decking condition, flashing details, access, local labor conditions, permits, warranties, and product choices can all change the final price.

Does the estimate include damaged roof decking?

No. Unknown decking repair is deliberately excluded because it is often discovered during tear-off. A contractor should state how replacement decking will be priced if it is needed.

How should I use this number?

Use it as a planning range and as a reasonableness check. Then compare contractor bids on the same material, tear-off scope, flashing, ventilation, cleanup, warranty, and decking terms.
