Cost to replace a 4,000 square foot roof, by roofing type
Roofers price by the square, and one square is 100 square feet, so a 4,000 square foot roof is 40 squares. The table multiplies 40 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 $4,000 to $20,000 on this roof.
| Roofing | Per square foot | Per square | 40 squares, no tear-off | With tear-off |
|---|---|---|---|---|
| Asphalt shingles | $4 to $12 | $400 to $1,200 | $16,000 to $48,000 | $20,000 to $68,000 |
| Standing seam metal | $4 to $30 | $400 to $3,000 | $16,000 to $120,000 | $20,000 to $140,000 |
| Wood shingles | $7 to $15 | $700 to $1,500 | $28,000 to $60,000 | $32,000 to $80,000 |
| Clay shingles | $12 to $25 | $1,200 to $2,500 | $48,000 to $100,000 | $52,000 to $120,000 |
| Slate | $12 to $25 | $1,200 to $2,500 | $48,000 to $100,000 | $52,000 to $120,000 |
These are HomeAdvisor's national ranges for materials and installation together, not prices for your area. On 40 squares, every $100 a roofer adds or takes off per square moves the total by $4,000. 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 4,000 square foot roof
At 40 squares, this is the biggest roof on the list, and every per-square difference between quotes is multiplied by 40. A roofer who charges $50 more per square costs $2,000 more on this roof.
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, $20,000, is more than the top of that range, so a roof this size costs more than most homeowners pay. Spread over 4,000 square feet, the average of $10,066 would be only $2.52 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 $6,000 to $16,000 on 40 squares. Booking in peak construction season can add 15 to 30 percent; on the middle of this roof's asphalt estimate, $44,000, that is $6,600 to $13,200.
Planning a 4,000 square foot roof
A new roof can add to the value of a house when the old one is worn out. HomeAdvisor says that on a house with a 20 to 30 year old roof, a new shingle roof may return as much as 60 percent of its cost. That helps if you plan to sell, but it is not a reason to replace a sound roof.
How the 4,000 square foot estimate is worked out
- Squares = 4,000 ÷ 100 = 40
- New asphalt shingle roof = 40 × $400 = $16,000 at the low end, and 40 × $1,200 = $48,000 at the high end
- Tear-off = 40 × $100 = $4,000 at the low end, and 40 × $500 = $20,000 at the high end
- Estimate = $16,000 + $4,000 = $20,000 at the low end, and $48,000 + $20,000 = $68,000 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 4,000 square foot roof, materials only
Doing it yourself, the shingles and felt cost about $6,324: 132 bundles of architectural shingles at $44.99 and 11 rolls of #15 felt at $34.99, with 10 percent waste, at McCoy's Building Supply prices checked in October 2026.
| 4,000 square foot roof in asphalt shingles | Cost |
|---|---|
| Shingles and felt, materials only | About $6,324 |
| Installed by a roofer, no tear-off | $16,000 to $48,000 |
| Installed by a roofer, with tear-off | $20,000 to $68,000 |
The gap of $9,676 to $41,676 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 4,000 square foot shingle order has the full list.
Is your roof really 4,000 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 4,000 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 | 3,795 sq ft | 69 by 52 ft | 3,588 sq ft |
| 6 in 12 | 1.118 | 3,578 sq ft | 67 by 50 ft | 3,350 sq ft |
| 8 in 12 | 1.202 | 3,328 sq ft | 64 by 48 ft | 3,072 sq ft |
| 10 in 12 | 1.302 | 3,073 sq ft | 62 by 46 ft | 2,852 sq ft |
| 12 in 12 | 1.414 | 2,828 sq ft | 59 by 44 ft | 2,596 sq ft |
At 6 in 12, a 4,000 square foot roof sits over a house of about 67 by 50 feet, with 3,350 square feet of floor. Going the other way, a one-story house with 4,000 square feet of floor has about 4,762 square feet of roof at the same pitch and overhangs. In asphalt shingles with a tear-off, that roof is about $23,800 to $81,000.
A two-story house with 4,000 square feet of floor space has about 2,000 on each level, so its roof is about 2,443 square feet, close to a 2,500 square foot roof. A garage or porch adds its own roof area; the roof area calculator measures yours.
