Cost to Replace a Roof by House Size: 1,500, 2,000 and 2,500 sq ft
Roof replacement cost for common house sizes from named cost sources, how roof area differs from floor area, and how pitch and stories change the number.
For a 2,000-square-foot house with an asphalt shingle roof, the cost sources put a replacement at roughly $7,000 to $16,000 for typical shingles, and far more for premium shingles or metal. Modernize reports $8,000 to $16,000 for a 2,000-square-foot home with asphalt (page updated October 6, 2026) 2. Fixr reports $7,200 to $38,400 for the same house size across every shingle grade, from basic 3-tab to luxury (updated January 21, 2026) 1.
The house's floor area is only a starting point. Roofers price the roof's surface, which is larger than the floor area on a one-story home and can be smaller on a two-story one, and it grows as the roof gets steeper. The tables below show the sources' figures for common house sizes, and the sections after them show how to get from floor area to roof area. For prices by material, see the roof replacement cost guide.
Asphalt shingle roof cost by house size
| House size (sq ft) | Fixr, roof size assumed | Fixr, all shingle grades | Modernize, asphalt |
|---|---|---|---|
| 1,500 | 1,800 sq ft 1 | $5,400 to $28,800 1 | $7,000 to $15,000 2 |
| 2,000 | 2,400 sq ft 1 | $7,200 to $38,400 1 | $8,000 to $16,000 2 |
| 2,500 | 3,000 sq ft 1 | $9,000 to $48,000 1 | not listed |
| 3,000 | 3,600 sq ft 1 | $10,800 to $57,600 1 | $12,000 to $25,000+ 2 |
Modernize also lists $9,000 to $18,000 for a 2,200-square-foot home 2. Fixr's wide ranges reflect its spread of $3 to $16 per square foot from 3-tab to luxury shingles 1; Modernize's narrower ones are for a standard asphalt roof. More detail is in asphalt shingle roof cost.
Metal roof cost by house size
| House size (sq ft) | Fixr, metal (Jan. 23, 2026) |
|---|---|
| 1,000 | $4,800 to $36,000 3 |
| 1,500 | $7,200 to $54,000 3 |
| 2,000 | $9,800 to $73,500 3 |
| 2,500 | $12,200 to $91,500 3 |
| 3,000 | $15,600 to $117,000 3 |
Fixr says a 1,000-square-foot home needs about 1,200 square feet of roofing and a 2,000-square-foot home needs 2,400 to 2,500 3. The range is wide because it runs from corrugated steel to copper. See metal roof cost.
Roof area is not floor area
Three things separate the two numbers:
- Stories. A one-story 2,000-square-foot house has a footprint of about 2,000 square feet. A two-story house with the same floor area has a footprint of about half that, so its roof can be much smaller. Modernize, for a 2,000-square-foot home, reports $9,000 to $14,000 for a single-story house and $10,500 to $16,000 for a two-story one 2, so a smaller roof does not always mean a smaller bill. The source does not say what drives the difference; ask the roofer.
- Overhangs and shape. Eaves extend past the walls, and garages and porches add roof. Modernize says roof area is typically 20% to 30% larger than the home's footprint 2. Fixr's own example assumes a 1,700-square-foot home with about 2,000 square feet of roofing 4.
- Pitch. Fixr says steeper roofs increase total roofing square footage even when the interior space stays the same 4.
A pitch multiplier, worked through
Pitch is written as rise over a 12-inch run, such as 6/12. The roof surface is longer than its flat footprint by a factor that follows from the right-angle triangle each rafter makes. By our arithmetic, that factor is about 1.054 for a 4/12 roof, 1.118 for 6/12, 1.202 for 8/12, and 1.414 for a 12/12 roof. This Old House's quick estimate uses 1.12 when the pitch is unknown 6.
An example, by our arithmetic: a one-story house with a 2,000-square-foot footprint and a 6/12 roof has about 2,000 × 1.118 = 2,236 square feet of roof, or about 22 squares, before overhangs. At Fixr's overall range of $3.75 to $11 per square foot for a roof replacement 4, that is about $8,385 to $24,596. It is a rough planning number, not a quote; a roofer measures the real roof.
The same roof size, different materials
This Old House, using Homewyse data, prices a 2,000-square-foot roof (roof area, not floor area) at $10,320 for asphalt, $26,300 for wood shake, $38,600 for metal and $44,420 for clay tile 5. At 1,500 square feet, its figures are $7,740, $19,725, $28,950 and $33,315 5. Those assume builder-grade material, medium labor costs and a low-slope, standard-shaped roof 5.
Getting a number for your house
Ask each roofer to state the measured roof area in squares, the pitch, the number of existing layers to remove, and the material and grade. If two quotes for the same house show very different square counts, ask why before comparing prices. Roof replacement cost per square foot explains the unit conversions, and how to choose a roofing contractor covers what to ask the company. You can compare quotes from roofing companies for your house.
