Cost to replace a 3,000 square foot roof, by roofing type
Roofers price by the square, and one square is 100 square feet, so a 3,000 square foot roof is 30 squares. The table multiplies 30 squares by the low and high installed cost of each roofing. The last column adds tearing off the old roof at $100 to $500 per square, which is $3,000 to $15,000 on this roof.
| Roofing | Per square foot | Per square | 30 squares, no tear-off | With tear-off |
|---|---|---|---|---|
| Asphalt shingles | $4 to $12 | $400 to $1,200 | $12,000 to $36,000 | $15,000 to $51,000 |
| Standing seam metal | $4 to $30 | $400 to $3,000 | $12,000 to $90,000 | $15,000 to $105,000 |
| Wood shingles | $7 to $15 | $700 to $1,500 | $21,000 to $45,000 | $24,000 to $60,000 |
| Clay shingles | $12 to $25 | $1,200 to $2,500 | $36,000 to $75,000 | $39,000 to $90,000 |
| Slate | $12 to $25 | $1,200 to $2,500 | $36,000 to $75,000 | $39,000 to $90,000 |
These are HomeAdvisor's national ranges for materials and installation together, not prices for your area. On 30 squares, every $100 a roofer adds or takes off per square moves the total by $3,000. The starting prices come from the store listings and cost guides under Sources, last checked in October 2026. Prices vary by region and season, so change any price to match your store or your quote.
What moves the price on a 3,000 square foot roof
At 30 squares, the choice of roofing moves the total more than anything else. The gap between the low end of asphalt and the high end of standing seam metal on this roof is tens of thousands of dollars, so settle the material before you collect quotes.
Next to what most people pay
HomeAdvisor says most homeowners spend $6,138 to $13,994 on a new shingle roof, $10,066 on average. Even the low end of this roof's asphalt estimate with a tear-off, $15,000, is more than the top of that range, so a roof this size costs more than most homeowners pay. Spread over 3,000 square feet, the average of $10,066 would be only $3.36 per square foot, below the $4 to $12 the cost guide gives for the roof alone.
It also says labor is about 60 percent of a new shingle roof, at $1.50 to $4.00 per square foot, which is $4,500 to $12,000 on 30 squares. Booking in peak construction season can add 15 to 30 percent; on the middle of this roof's asphalt estimate, $33,000, that is $4,950 to $9,900.
Planning a 3,000 square foot roof
Get at least one quote in asphalt and one in the metal you are considering. HomeAdvisor gives standing seam at $4 to $30 per square foot because the figure covers metals from steel to copper, so ask which metal and what gauge.
How the 3,000 square foot estimate is worked out
- Squares = 3,000 ÷ 100 = 30
- New asphalt shingle roof = 30 × $400 = $12,000 at the low end, and 30 × $1,200 = $36,000 at the high end
- Tear-off = 30 × $100 = $3,000 at the low end, and 30 × $500 = $15,000 at the high end
- Estimate = $12,000 + $3,000 = $15,000 at the low end, and $36,000 + $15,000 = $51,000 at the high end
If a quote already includes the tear-off, choose No tear-off in the calculator above so it is not counted twice.
Shingles for a 3,000 square foot roof, materials only
Doing it yourself, the shingles and felt cost about $4,769: 99 bundles of architectural shingles at $44.99 and 9 rolls of #15 felt at $34.99, with 10 percent waste, at McCoy's Building Supply prices checked in October 2026.
| 3,000 square foot roof in asphalt shingles | Cost |
|---|---|
| Shingles and felt, materials only | About $4,769 |
| Installed by a roofer, no tear-off | $12,000 to $36,000 |
| Installed by a roofer, with tear-off | $15,000 to $51,000 |
The gap of $7,231 to $31,231 is the roofer's labor and costs, plus the nails, drip edge, flashing, vents, ridge cap, delivery and tax the materials figure leaves out. The 3,000 square foot shingle order has the full list.
Is your roof really 3,000 square feet?
The most common mistake in a roof estimate is using the floor area as the roof area. This table works back from a 3,000 square foot roof to the house under it, 4 feet long for every 3 wide with 12 inch overhangs.
| Roof pitch | Pitch multiplier | Flat area covered | House that fits | Floor area |
|---|---|---|---|---|
| 4 in 12 | 1.054 | 2,846 sq ft | 59 by 44 ft | 2,596 sq ft |
| 6 in 12 | 1.118 | 2,683 sq ft | 58 by 43 ft | 2,494 sq ft |
| 8 in 12 | 1.202 | 2,496 sq ft | 55 by 41 ft | 2,255 sq ft |
| 10 in 12 | 1.302 | 2,305 sq ft | 53 by 40 ft | 2,120 sq ft |
| 12 in 12 | 1.414 | 2,121 sq ft | 51 by 38 ft | 1,938 sq ft |
At 6 in 12, a 3,000 square foot roof sits over a house of about 58 by 43 feet, with 2,494 square feet of floor. Going the other way, a one-story house with 3,000 square feet of floor has about 3,606 square feet of roof at the same pitch and overhangs. In asphalt shingles with a tear-off, that roof is about $18,000 to $61,300, close to the figures for a 3,500 square foot roof.
A two-story house with 3,000 square feet of floor space has about 1,500 on each level, so its roof is about 1,857 square feet, close to a 1,800 square foot roof. A garage or porch adds its own roof area; the roof area calculator measures yours.
Before you sign
Get both warranties in writing. The shingle maker's warranty covers the shingles, and the roofer's own warranty covers the work, and on a roof this size the work is most of the bill. Ask how long the roofer stands behind leaks from the installation, and what voids the shingle warranty.
Other roof sizes
In asphalt shingles with a tear-off, a 2,500 square foot roof is $12,500 to $42,500 and a 3,500 square foot roof is $17,500 to $59,500.

Common questions
How much does it cost to replace a 3,000 square foot roof?
About $15,000 to $51,000 with asphalt shingles and a tear-off, or $12,000 to $36,000 without, by HomeAdvisor's national figures. Quotes from roofers in your area are the only firm number.
How much does a 3,000 square foot metal roof cost?
For standing seam metal, about $12,000 to $90,000 before tear-off, at HomeAdvisor's $4 to $30 per square foot installed. The range is wide because it covers metals from steel and aluminum up to zinc and copper.
How much does it cost to tear off a 3,000 square foot roof?
About $3,000 to $15,000, at HomeAdvisor's $1 to $5 per square foot for removing and hauling away the old roofing. Some quotes already include it.
Is a metal roof worth it on a 3,000 square foot roof?
It depends on how long you will stay. HomeAdvisor puts standing seam at $4 to $30 per square foot installed, against $4 to $12 for asphalt shingles, and says most asphalt shingles last 15 to 20 years. Price both on your roof before you decide.
Why is my roof quote more than the average roof cost?
The average covers smaller roofs too. HomeAdvisor says most homeowners spend $6,138 to $13,994 on a new shingle roof, and a 3,000 square foot roof is well past that even at the low end of the per-square cost.
Is a 3,000 square foot roof the same as a 3,000 square foot house?
No. A one-story house with 3,000 square feet of floor has about 3,606 square feet of roof at 6 in 12 with 12 inch overhangs, and a 3,000 square foot roof fits a one-story house of about 2,494 square feet.
