If your roofing professional discovers structural issues in the rafters after removing your old roof, you could have to pay an additional $1,000 to $10,000.
Roofing Labor Cost Per Square
With a few different variables at play, roofing labor is generally between $1.50 and $3.00 per square foot. If your roofing professional is using Per Square in the bid (10x10 area), their prices for labor will reflect this multiplied out by 100 to show between $150 and $300 per square. According to the United States Census, the average roof is 17 squares or about 1,700 square feet.
Roofing Cost Per Square Foot
When calculating roofing costs per square, asphalt shingles run from $350 and $500 per square, metal or tin roofs costs $600 to $1,200 per square, and concrete or clay costs between $1,200 and $1,800 per square. If you are replacing your current roof, add $125 to $500 per roofing square for old roof removal.

Cost to Replace Asphalt Shingle Roof
Replacing an asphalt roof with new shingles will cost between $5,400 and $9,000, or an average of $7,211 for a 2,000 square foot home not including old roof removal. The actual cost will vary depending on whether it is a composite asphalt shingle roof or a fiber cement (concrete) composite shingle installation.
Asphalt is the least expensive solution, with a cost to remove the previous asphalt roof and install a new one coming to $7,850 for a 1,500 square foot home, while the same project undertaken and installing concrete shingles instead of asphalt will cost $24,950.
Metal Roof Costs

The average price range of metal roofing is $600 to $1,200 per square installed vs. an asphalt shingle roof, which costs $300 to $700 per square installed. The cost to install a metal roof will vary depending on which type of metal is selected, which manufacturer made it, and the size of your home.
| Material | Material Cost (SF) | Total Cost (SF) | Total Cost (1,200 SF) |
|---|---|---|---|
| Galvalume | $1.63 | $6.38 | $7,700 |
| Tin (Terne) | $4.00 | $8.75 | $10,500 |
| Steel Standing Seam | $4.25 | $10.25 | $12,300 |
| Stainless Steel | $8 | $15.50 | $18,600 |
| Copper | $22.50 | $28.50 | $30,600 |
Tin Roof Cost
The average cost to install a new tin roof is $10,500 with most homeowners paying $875 per square. New tin roofs are no longer just made of tin, but made of steel and then coated with tin, and these days they are referred to as Terne.
Steel Roof Cost
The national average cost to install a steel roof is $12,300, or $1,025 per square. For stainless steel, which can maintain its appearance for 60 years, you can expect to spend around $18,600 or $1,600 per square.
Copper Roof Cost
Copper roofing is generally the most expensive roofing solution with pricing around $30,600 or ranging from $1,500 to $2,000 per square. Since it's installed less often, not every roofer has significant experience in working with it, and the labor tends to cost a little more.
Roof Tile Replacement Cost
Roof tile replacement costs between $1,400 and $1,600 per square on average for concrete tile, Spanish tile, and clay tile. Tile roofing tends to weight a lot and will cost $1,000 more if your entire roof framing needs an upgrade to support the extra weight.
Clay Tile Roof Cost
Clay roof tiles are right up there with entry-level copper in regards to price, which averages around $1,500 per square. The average cost to install a new clay tile roof costs between $15,000 and $45,000 depending on your roof size.
Concrete Roof Tile Prices
Like clay tiles, concrete tiles also carry a $1,500 per square price, with the average installation costing $22,500 to $30,000. Depending on the current structural integrity of the roof framing, it is possible some repair or strengthening work will need to be done on the rafters to support the extra weight of these heavier products.
Spanish Tile Roof Cost
Spanish roof tiles generally have a little more design to them than entry-level clay or concrete, and you can expect to pay in the region of $1,500 to $1,600 per square for the install, and around $1,000 first if your entire roof framing needs work to support the added weight.
Slate Roof Cost
Slate roofing is one of the more expensive materials with a national average cost of between $22,200 to $37,000 with most homeowners spending from $14,800 to $44,400. Slate roofing costs $1,480 per square for materials and professional installation. Because it is a natural stone, outside of direct impact from severe storms causing damage from significantly large branches, etc., a slate roof is regarded to be something which will last anywhere from 70 to 200 years, as long as the roof framing underneath remains intact.
Wood or Cedar Shake Roof Cost
The national average for wood or cedar shake roofing is between $12,000 and $16,000, or $800 per square. The anticipated life span for most wood shake roof installations is between 30 and 40 years.
Wood shake is available in a range of thicknesses, which will affect the price as well as the protection they offer. Additional treatments are available for a class C fire rating at $0.85 per square foot, and a wood shake roof will require maintenance to clean off debris before the rainy season starts to prevent mold and moss accumulating. While they are most commonly made from cedar, followed by spruce and treated pine, you can also get synthetic cedar shake like Brava Cedar Shake from Brava which have a 50-year lifespan and requires no maintenance.
Flat Roof Replacement Cost
Flat roof replacement costs $50 to $400 per square depending on your choice of roofing materials. Instead of sheets of metal, shingles, or tiles, layers of plastic or rubber are laid down on a flat roof and sealed by melting with the flame from a blowtorch; or a compound is sprayed over the entire surface of the roof to create a weatherproof finish. Flat roofing solutions also have an impact on reducing heat loss through the roof.
- Modified Bitumen Roof Cost – Modified bitumen is an asphalt product fortified with either a polyester or fiberglass matting to add strength and increase its useable lifespan. Using Bitumen on a flat or low slope roof and costs between $150 and $400 per square.
- PVC Roof Cost – PVC as a membrane roof solution is installed in widths of 6’ to 18’ wide and usually laid on top of an insulation board, and sometimes requires additional edge fastening which causes a minor spike in the labor costs—making the range of roll roofing cost go from $70 to $110 per square installed.
- Built-Up Roof – In a built-up roof, after a few layers of sheet ply are laid down, they are fused together with melted asphalt, leaving the top layer the option to be a brighter color to reflect heat instead of absorbing it. Costs range between $50 to $80 per square
- Spray-On Roof – With a spray-on roof, polyurethane solution is evenly applied for as little as $30 per square, acrylic for $60 per square, or the premium option of silicon spray averages $85 per square or more.
Rubber Roofing Cost
- TPO Roofing – TPO roofing costs between $550 and $950 per square or between $5.50 and $9.50 per square foot installed. Thermoplastic polyolefin roofing, which is not plastic but a rubber, is sold in rolls of either 6’ or 6’6” wide and 100’ long as well as rolls of 3’ wide for edging and 12’ wide for commercial or large roofs.
- EPDM Roofing – The national average cost for EPDM roofing is $760 per square for materials and $1,110 per square installed. For the 0.45 loose membrane, and for the 0.60 adhered membrane it is $970 per square and $1,450 installed, with another $510 per square for the adhesive or $650 per square for the adhesive applied.
Solar Roof Cost
At $21.85 per square foot, the cost of a Tesla solar roof is between $52,000 and $70,600 with an additional $17,100 for 2 Powerwall batteries. Over 30 years, solar tiles will generate approx. $49,000 worth of free energy and homeowners can take advantage of government tax credits of 30% of the install cost.
- -$70,600 Cost of roof
- -$17,100 Cost of 2 Powerwall batteries
- +$49,000 Value of energy generated over 30 years
- +$21,400 Tax credit
- $17,300 Net cost over 30 years
With the Tesla solar roofing tiles, you have to request a consultation regarding the installation and labor costs, which are estimated to be around an additional $8,000 to $10,000. Calculations are based on an estimated 2,160 square foot roof. Data provided by Google Project Sunroof.
Calculating Roofing Cost
Any calculations for your new roofing system could include the need to replace flashing, soffits, sheathing, repairs around skylights, mold removal, framing strengthening, or repairs you won’t know about until the roof is exposed or inspected by a professional.
One of the essential elements in working out the cost for your new roof is factoring in the pitch of the roof. The angle of your roof will most likely have a pitch between 4/12 and 9/12 (18.4 degrees and 36.9 degrees).
- Slope - Slope is the incline of the roof expressed as a ratio of the vertical rise to the horizontal run, where the run is some portion of the span. This ratio is always shown as inches per foot.
- Pitch – Pitch is the incline of the roof expressed as a fraction derived by dividing the rise by the span, where the roof span is the distance between the outside of one wall's top plate to another.
If you want to measure the pitch of your roof before you engage with roofing contractors to get quotes, you can check this article from InterNACHI on how to calculate the pitch and slope of a roof.
When considering your roofing options, try using the following formula:

| 2,400 | $792 – $1,704 |
| 3,400 | $1,122 – $2,414 |
Roofing Permit Cost
A roofing permit costs $150 to $500 depending on where you live and the scale of your roofing replacement project or repair work. Local governing authorities like building departments typically require a permit for replacing a roof, and in some cases for roofing repairs that go beyond an area of 60 to 80 square feet.
Roof Removal Costs
Roof removal costs $1.63 per square foot for a single-story home and as much as $1.96 per square foot for a 3-story townhome. Most homeowners spend between $1,500 and $3,000 total when hiring a professional and the cost goes up from there for high-end materials like slate or other stone tiles which are heavier.
On older homes, or homes that have been impacted by severe storms, additional roofing structure issues may be discovered by your roofing professional, which could result in an additional cost for the project in the range of between $1,000 to $10,000. You may not see this as a separate cost in the bid for your roof replacement; it may say that it's included.
Average Price of Replacing Your Roof vs. Repairing
The national average cost to repair a roof ranges from $200 to $3,000, with most people paying between $225 and $1,150 depending on the extent of the damage, and the type of roofing materials on the roof that needs repairing. If there is either extensive damage or your roof is about 20 years old, and it needs replacing, the average price to replace your roof is around $7,211.
| Roof Repair Extent | Average Cost |
|---|---|
| Small Roof Repairs | $200–$500 |
| Medium Roof Repairs | $500–$1,500 |
| Big Roof Repairs | $1,000–$3,000 |
Roof Repair vs. Replacement
Your roof could still be in good condition, and not show any signs of leaking, but if it is 20 years old or older, you can prevent an extensive amount of damage to the interior of your home and its contents by having someone come out to assess the situation. According to building supplies manufacturer Owens Corning, the following is a list of signs you're roof needs to be replaced:
- Shingle edges are curled, or shingle tabs are cupped or cracked.
- Bald spots where granules are missing
- Your roof is at least 20 years old.
- The roof looks old and worn.
- Dark streaks from airborne algae
- Moss
Cost to Redo a Roof with a Different Type
If you are replacing your existing asphalt roof with a roof type that is heavier, like slate or stone tiles, the potential exists where you may need some structural reinforcement for the rafters and joists in the roof framing structure to support the additional weight. The reinforcement alone will average between $500 and $1,500 depending on the size of the home and the amount of reinforcement needed. Add the cost for your chosen roofing material plus labor on top of that.
Roofing Warranty
Many roofing warranties are 25-years, but a small subset of roofing material manufacturers provides a lifetime warranty which typically applies to high-end products. Some insurance companies offer discounts if you install impact-resistant shingles because of the reduced likelihood of damage causing claims. Check with your insurance broker before beginning your project to see if they offer any discounts and if they are restricted to specific brands.
Roofing Insurance Considerations
After high winds or severe hailstorms rip off or damage tiles in your area, you’ll find inexperienced roofers going door-to-door trying to talk you into letting them replace the roof over your home. They’ll take care of working with the insurance company. Most of these companies will have disappeared within a year or two of doing the work, and you can forget about the warranty.
Always check online reviews, reputation, plus longevity before you choose your roofer, no matter what price is offered at your door. All roofing contractors are happy to inspect your roof and show you photos of any damage they find, and also to work with your insurance company.
Another thing to consider is the amount your home insurance will increase per month after a claim. If your roof can be replaced with asphalt tiles and the entire job costs a few thousand, it might be worth paying for it yourself vs. paying a deductible and higher payments over the next five years.
Frequently Asked Questions
How Much Roofing Do I Need?
The amount of roofing materials it takes to cover an incline is more than if the area was completely flat. If you have a flat roof, then the square footage of the uppermost floor of your house is the total for materials needed plus 10% more for waste.

DIY Roof Replacement vs. Hiring a Roofer
For homeowners looking at replacing their roof instead of hiring a professional, an asphalt roof will cost $3,000 less (for 3-tab shingles) to $6,000 less (for architectural shingles). However, while small roof repairs are cheap and relatively easy to carry out by the homeowner, as long as safety precautions are taken, roofing a home is better done by professional roofers. The downsides of completing the work as a DIY project are:
- In removing the original roof, you may cause issues that will lead to leaks.
- Once the old roof is off, you could miss structural issues or things that will contribute to more leaks.
- You might not create a perfect weather seal to protect your home from the rain when installing the new roof.
- You could introduce issues that translate to increased utility costs from heating or cooling.
- You could fall from your roof.
- You could negatively impact the resale value of your home.
Your roof is the single biggest surface barrier between you and the elements. Given the importance of the roof, and the potential for significant problems, we suggest looking for bids from the roofing professionals we have on HomeGuide before making a final decision to do the work yourself.
