Cost to replace a 1,500 square foot roof, by roofing type
Roofers price by the square, and one square is 100 square feet, so a 1,500 square foot roof is 15 squares. The table multiplies 15 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 $1,500 to $7,500 on this roof.
| Roofing | Per square foot | Per square | 15 squares, no tear-off | With tear-off |
|---|---|---|---|---|
| Asphalt shingles | $4 to $12 | $400 to $1,200 | $6,000 to $18,000 | $7,500 to $25,500 |
| Standing seam metal | $4 to $30 | $400 to $3,000 | $6,000 to $45,000 | $7,500 to $52,500 |
| Wood shingles | $7 to $15 | $700 to $1,500 | $10,500 to $22,500 | $12,000 to $30,000 |
| Clay shingles | $12 to $25 | $1,200 to $2,500 | $18,000 to $37,500 | $19,500 to $45,000 |
| Slate | $12 to $25 | $1,200 to $2,500 | $18,000 to $37,500 | $19,500 to $45,000 |
These are HomeAdvisor's national ranges for materials and installation together, not prices for your area. On 15 squares, every $100 a roofer adds or takes off per square moves the total by $1,500. 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 1,500 square foot roof
The time of year matters as much as the size here. HomeAdvisor says booking during peak construction season can raise the price by 15 to 30 percent, and that spring or fall is usually the most affordable time.
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. Spread over 1,500 square feet, the average of $10,066 works out to $6.71 per square foot, all in. That sits in the lower half of the $4 to $12 the guide gives for the roof alone, before the $1 to $5 for a tear-off.
It also says labor is about 60 percent of a new shingle roof, at $1.50 to $4.00 per square foot, which is $2,250 to $6,000 on 15 squares. Booking in peak construction season can add 15 to 30 percent; on the middle of this roof's asphalt estimate, $16,500, that is $2,475 to $4,950.
Planning a 1,500 square foot roof
If the roof is not leaking yet, get quotes in the slow season and book ahead. On a roof this size, 15 to 30 percent can be the difference between the low and the middle of the estimate on this page.
How the 1,500 square foot estimate is worked out
- Squares = 1,500 ÷ 100 = 15
- New asphalt shingle roof = 15 × $400 = $6,000 at the low end, and 15 × $1,200 = $18,000 at the high end
- Tear-off = 15 × $100 = $1,500 at the low end, and 15 × $500 = $7,500 at the high end
- Estimate = $6,000 + $1,500 = $7,500 at the low end, and $18,000 + $7,500 = $25,500 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 1,500 square foot roof, materials only
Doing it yourself, the shingles and felt cost about $2,425: 50 bundles of architectural shingles at $44.99 and 5 rolls of #15 felt at $34.99, with 10 percent waste, at McCoy's Building Supply prices checked in October 2026.
| 1,500 square foot roof in asphalt shingles | Cost |
|---|---|
| Shingles and felt, materials only | About $2,425 |
| Installed by a roofer, no tear-off | $6,000 to $18,000 |
| Installed by a roofer, with tear-off | $7,500 to $25,500 |
The gap of $3,575 to $15,575 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 1,500 square foot shingle order has the full list.
Is your roof really 1,500 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 1,500 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 | 1,423 sq ft | 41 by 31 ft | 1,271 sq ft |
| 6 in 12 | 1.118 | 1,342 sq ft | 40 by 30 ft | 1,200 sq ft |
| 8 in 12 | 1.202 | 1,248 sq ft | 38 by 29 ft | 1,102 sq ft |
| 10 in 12 | 1.302 | 1,152 sq ft | 37 by 28 ft | 1,036 sq ft |
| 12 in 12 | 1.414 | 1,061 sq ft | 35 by 26 ft | 910 sq ft |
At 6 in 12, a 1,500 square foot roof sits over a house of about 40 by 30 feet, with 1,200 square feet of floor. Going the other way, a one-story house with 1,500 square feet of floor has about 1,857 square feet of roof at the same pitch and overhangs. In asphalt shingles with a tear-off, that roof is about $9,300 to $31,600, close to the figures for a 1,800 square foot roof.
A two-story house with 1,500 square feet of floor space has about 750 on each level, so its roof is about 967 square feet, close to a 1,000 square foot roof. A garage or porch adds its own roof area; the roof area calculator measures yours.
Before you sign
A 1,500 square foot roof on a two-story house is not the same job as on a one-story ranch. HomeAdvisor says high roofs, such as on multi-story houses, cost more, so compare quotes for your actual house.
Other roof sizes
In asphalt shingles with a tear-off, a 1,200 square foot roof is $6,000 to $20,400 and a 1,800 square foot roof is $9,000 to $30,600.

Common questions
How much does it cost to replace a 1,500 square foot roof?
About $7,500 to $25,500 with asphalt shingles and a tear-off, or $6,000 to $18,000 without, by HomeAdvisor's national figures. Quotes from roofers in your area are the only firm number.
How much does a 1,500 square foot metal roof cost?
For standing seam metal, about $6,000 to $45,000 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 1,500 square foot roof?
About $1,500 to $7,500, at HomeAdvisor's $1 to $5 per square foot for removing and hauling away the old roofing. Some quotes already include it.
When is the cheapest time to replace a 1,500 square foot roof?
HomeAdvisor says spring or fall is usually the most affordable time, and that peak construction season can add 15 to 30 percent. Booking ahead, before the roof starts to leak, gives you the most choice.
How much more does a 1,500 square foot roof cost on a two-story house?
There is no fixed figure, but HomeAdvisor says high roofs, like those on multi-story houses, cost more to shingle because they are harder and riskier to reach. Expect the quotes to land higher in the range.
Is a 1,500 square foot roof the same as a 1,500 square foot house?
No. A one-story house with 1,500 square feet of floor has about 1,857 square feet of roof at 6 in 12 with 12 inch overhangs, and a 1,500 square foot roof fits a one-story house of about 1,200 square feet.
