How Much Does a New Roof Cost?

Part of Decks, Fences & Roofing

Quick answer

A new asphalt-shingle roof runs roughly $5,500–$16,000 installed for a typical house (US national average, June 2026), or about $450–$750 per roofing square (100 ft²). Metal, tile and slate cost two to five times more. Roof size, pitch, material and tear-off drive the price.

Roofers price by the "square" — 100 square feet of roof surface. A new roof's cost is the price per square (material plus labor) times the number of squares, plus tear-off of the old roof and any deck repairs.

Installed cost per square by material

Roofing materialInstalled cost per square (100 ft²)
3-tab asphalt shingles$350–$500
Architectural asphalt shingles$450–$750
Wood shakes$700–$1,200
Metal (standing seam)$900–$1,600
Clay / concrete tile$1,000–$2,000
Slate$1,500–$3,000

Typical total by roof size (architectural asphalt)

Roof area is the sloped surface, not the floor plan — a steeper pitch adds surface and cost. Use the roof's footprint and pitch in the roofing calculator to get the squares, then multiply by a per-square figure above.

What else moves the price

  • Tear-off: removing one old layer adds roughly $100–$150 per square.
  • Pitch and height: steep or multi-story roofs need staging and cost more in labor.
  • Complexity: hips, valleys, dormers, skylights and chimneys mean more flashing and waste.
  • Deck repair: rotten sheathing found during tear-off is an add-on, often $70–$100 per sheet.

FAQs

How much does it cost to replace a roof?

For a typical home with asphalt shingles, about $5,500–$16,000 installed including tear-off, or roughly $450–$750 per roofing square. Larger, steeper or more complex roofs and premium materials cost more.

Why is a new roof so expensive?

Most of the cost is labor — tearing off the old roof, hauling debris, and installing on a sloped, elevated surface — plus underlayment, flashing, drip edge and the shingles themselves. Steep and cut-up roofs take more time and waste more material.

Is it cheaper to overlay or tear off?

Overlaying (a second layer over the old shingles) saves the tear-off cost but is allowed only once, hides deck problems, and shortens the new roof's life. A full tear-off costs more upfront but is the better long-term value.
