How Much Does a Metal Roof Cost?
Hello, my friend, hello again; today we come together to talk about How Much Does a Metal Roof Cost? and hope the blog can help you.
Think beyond shingles and slate: Metal roofs are durable, energy efficient, and surprisingly affordable. With some planning and budgeting, you can have something unique that suits your house and saves on the overall metal roof cost.
Highlights
- The typical cost range to install a metal roof is $5,659 to $17,314, with a national average cost of $11,452.
- The exact cost will depend on the type of metal, the roof size and style, the cost of labor and permits, and the home’s geographic location.
- The benefits of installing a metal roof include lower homeowners insurance premiums, longevity, energy efficiency, resistance to weather and fire, and return on investment.
- Metal roof installation is not a project for a casual DIYer; not only can metal roof installation be dangerous for inexperienced homeowners, but DIY installation can void the roof’s warranty.
Time for a new roof? You’ll find lots of options on the market. If you’re tired of the default asphalt shingle roof but not interested in the high maintenance of wood shakes or the structural work needed for heavy tile or slate, consider the option of a metal roof. Once relegated to industrial and agricultural applications, metal roofs are popping up in residential areas with increasing frequency. That’s because metal roofs offer a bevy of benefits: They’re environmentally friendly, energy-efficient, come in a wide range of styles, and last between 70 and 100 years. The fact that the initial outlay for metal roofing is a bit higher than some roof types is justified by the fact that you’ll probably never need to replace it. These roofs can be designed and installed to create almost any look a homeowner wants.

Metal Roof Cost: How to Calculate the Cost of a Metal Roof
You may know the size of your home, and you may even know the square footage of your roof—but calculating the cost of a metal roof is a little more complicated. Roofing prices change with the demand for materials and the cost of acquiring them, and labor costs vary regionally and seasonally. As a base calculator, use the following formula:
Materials + Labor and Installation in My Area + Overhead = Total Cost of Metal Roofing Near Me
Each of these three components should make up one-third of your project cost.
As you begin calculating, keep in mind that roofers use a unique unit of measure called a roofing square to calculate material prices, equivalent to 100 square feet (a 10-foot by 10-foot square). This calculation will itemize the total material cost for that section, so the number of squares needed to cover your roof will drive the rest of the expenses. To accurately estimate, plan on over-ordering material by 5 to 20 percent to account for waste on cuts and any pattern matching. Labor costs will vary, so plan to collect multiple estimates with itemized cost lists before you choose. Overhead will include costs such as shipping, tools, permits, and insurance.
Factors in Calculating Metal Roof Cost
How much does a new roof cost? To accurately plan and budget for a metal roof, you’ll need to consider many of the same elements as you would with any other roofing style. Some of these costs are nonnegotiable, while others can be increased or reduced based on selections and some thorough price comparisons.
Geographic Location
Material and installation costs vary significantly based on where you live. New England, the West Coast, Hawaii, and Alaska are where roofing installation is most expensive. Prices tend to be lower in the Midwest and southern rural areas. Since your home location isn’t something you can change, your best plan is to seek out numerous estimates to make sure you’re getting the most competitive contract if you live in one of the more expensive regions.
Material Type and Form
Not all metal roofs are the same: There is actually a relatively wide range of metal materials that can be fashioned into roofing sheets or tiles, and what you choose can significantly influence the cost. The least expensive is an alloy called Galvalume, which can cost as little as $75 to $200 per roofing square. Galvanized steel will increase the cost to $150 to $350 per square, and aluminum can range from $150 to $600 per square. Steel, stone-coated steel, zinc, and tin all gradually increase in price, and the luxury materials like stainless steel ($400 to $1,200 per square) and copper ($800 to $1,500 per square) round out the higher end of the material costs. Lead tops the list at more than $1,000 per square, depending on the core material in the lead. Those materials do boast a longer lifespan and less maintenance, though.
Roofing Style
Metal roofs are available in several different configurations. The most basic style is sheet metal, which can be flat, ribbed, or crimped to change the appearance and function. Sheet metal, on average, costs $75 to $600 per roofing square, depending on the material. Standing seam metal roofs are strips or panels of metal whose edges have been folded together to create a ribbed seam. The additional craftsmanship of this style raises the cost to $200 to $1,000 per roofing square and results in a higher installation cost. Finally, metal roofing is available as strips that are pressed or stamped to look like individual shingles, shakes, or tiles, costing between $200 and $600 per roofing square.
Roof Size, Slope, and Pitch
The size of the roof will determine how much material you need to order and how much time it will take to install. Large roofs with complex designs and many sides will require a larger crew or more time, increasing labor costs.
The pitch of the slopes on the roof affects the amount of material you need to order, the method of installation, and the amount of safety equipment installers will need to use. Roofs with a steep pitch (greater than a 3-inch rise per foot) will cost more in labor, as it is more dangerous to work on, takes longer, and requires additional material. Roofs with a lower pitch (less than a 3-inch rise per foot) are the easiest to work on, as they are usually walkable and need less safety equipment and material. The most expensive roof pitch is a curved one: These roofs require additional safety equipment because it’s easier to lose one’s footing on a curved surface, and applying panels or shingles to a curved roof without damaging the materials is tricky and requires extra time and skill.
Underlayment
If your installer were to mount a metal roof directly onto the studs and sheathing of your home, you’d never sleep during a rainstorm again (and you’d also have leaks everywhere). Specially designed underlayment creates a barrier between the house and the roof, muffling sound, providing insulation, and stopping leaks. If your roof has exposed fasteners, specialized peel-and-stick gummy underlayment should be used to prevent leaks from fasteners subject to the weather. Underlayment will cost between $4 and $5 per square foot. Check with your contractor—this cost may be incorporated into the material or installation of the metal roof cost within the contract.
Labor and Installation
The labor cost for metal roof installation is significant—it can be as much as three to seven times the cost of the materials. The average labor cost is $3,000, but adding in pitched angles, complex structures, and size, this cost can range up to $10,000 or more. This should include the finish pieces of the roof like drip edges, ridge caps, flashing, fasteners, gable edges, ridge caps, and coatings.

Permits
Nearly every local government will require a building permit for a new roof. Because the roof is such a critical component of a house’s structure, the building department will want to ensure the building’s quality and materials (and assess the property taxes on your home if the roof constitutes an improvement). Consult your town’s building department for permit rates. If you live in a dues-paying homeowners association, there may be additional permits or approval to request if you’re changing the material or color of your roof; check these at the same time, so you don’t incur a fine later.
Additional Costs and Considerations
The materials, installation, and permits for a new metal roof aren’t the only costs to consider. Quality preparation and finish work can make the difference between a roof that just covers the house and one that complements the home and wows neighbors. While some of these elements are optional, they’re all essential to consider.
Painting or Coatings
Metal roofing arrives with a coating of zinc or a combination of aluminum and zinc. This will protect your roof for a while. Still, it’s an option to add an additional polymer coating layer for extra protection and longevity and to prevent hazing, which can occur as the metal oxidizes. Alternatively, some homeowners have a particular image of a metal roof in their mind that can’t be met with bare metal, and those homeowners have the option to paint their roof. The average cost to seal or paint a roof ranges between $300 to $1,500 based on the size of the roof and the grade of the coating selected.
Cost to Remove an Existing Roof
If you’re replacing an existing roof, you’ll need to include the cost of removing the old one and carting away the debris. Removal will add $1,000 to $1,500 to the total project budget. Depending on the type of roof being removed, there may be some additional permits required to dispose of the material—a contractor should have this information, but it’s a good idea to check with the town to be sure.
Accessories
Most new roof installations will include gutters and hardware, but if you have skylights or solar panels, you’ll need to factor in the cost of replacing them or removing and reinstalling them. Your contractor may choose different configurations of panels to accommodate solar arrays or skylights, and other custom accessories will require careful planning, placement, materials, and labor.
Flashings, Vents, and Chimneys
One of the most important functions that a roof performs is to keep water and extreme temperatures out of a home—but it also allows an HVAC system and plumbing to work. The plumbing vent stack, vents for air conditioning units and laundry appliances, and chimneys from boilers may all egress through the roof. Working around these features will require expert installation methods. If a house is older, replacing the chimneys and vents themselves may be an added cost. The flashing around all of these items, as well as around windows, skylights, dormer windows, and roof valleys, add material and labor costs.
Metal Roof Cost: Types of Materials
The range of materials available for metal roofing is wider than you might think. Each material type and style has a unique look, along with individual benefits and drawbacks. You’ll want to consider the look you’re going for, the style of your home, and in some cases, how long you plan to remain in your home. While metal roofs are not significantly more expensive than other types, in the long run, the initial cost is a bit higher. If you’re planning to move soon, a luxury material for a metal roof may not be the best option.

Steel
A basic steel roof can cost as little as $75 to $350 per roofing square. Usually galvanized or coated in Galvalume, steel roofs are efficient, inexpensive, and available in both panels or shingles.
On the other hand, stainless steel is one of the more expensive options—$400 to $1,200 per roofing square—but with good reason. Stainless steel roofing, which comes in both sheets and tiles, resists rust and corrosion and is durable. It is used as the roofing and facing on large office buildings and skyscrapers (including the Chrysler Building in New York City) because it holds up well to weather and remains glossy and attractive.
Galvanized
A zinc-coated steel core results in a low-maintenance, durable roofing material that increases a home’s energy efficiency. Ringing up at $150 to $350 per roofing square, galvanized material resists impact denting (so it’s ideal for areas with frequent hail) and develops a patina over time. It can suffer from corrosion and may require some additional maintenance and recoating.
Galvalume
Galvalume also features a steel core but is covered with a material that is a combination of zinc and aluminum. It’s less expensive than galvanized material at $75 to $200 per square but is more corrosion resistant than plain steel. Galvalume is available in many colors (although without regular resealing, colors can fade) and is quite flexible compared to other materials, so it can be helpful in applications where curves or shaping are necessary.
Tin
Tin used to be a common roofing material, especially in situations where waterproofing was important. Today, most tin products are actually a steel core with a tin and zinc or tin and lead coating called Terne. Extremely durable and resistant to corrosion, Terne develops a gray patina with time and costs around $350 to $1,500 per square.
Aluminum
The cost of an aluminum roof varies heavily depending on whether you select sheets or shingles, running as little as $150 per square for sheets or as much as $600 per square for shingles. Naturally reflective, flexible, and recyclable, aluminum is one of the most naturally energy-efficient materials you can choose for your roof. You may see references to aluminum roof panels when you’re shopping; these products are designed to cover patios or porches and are sheets of aluminum with a foam core. Available in a range of colors and styles, these panels are insulated and come in DIY kits for $3,000 to $5,000.
Copper
Copper has a rich natural beauty, and combined with its long, low-maintenance lifespan and rust-free properties, this material is one of the most expensive roofing materials you can choose. In addition, copper is easily warped or dented during installation (though quite solid after it’s properly in place), so it requires a skilled professional and extra time to install. At $800 to $1,500 per square, it’s a classic, lovely option for many homes and an investment that will last.
Zinc
Zinc is used as a coating for other metal roof materials but can also stand alone as a covering. Zinc forms its own coating as it ages and oxidizes and has the unique quality of healing itself and reseal dents and scratches when they occur. It’s durable and long lasting. Zinc shingles fall at the lower end of the cost range ($600 per square), while standing seam installations can reach or surpass the higher end ($1,000 per square).
Lead
Although you don’t want it in your paint or water, lead makes an outstanding roofing material. While manufacturers have performed studies that show lead is a safe roofing material, it’s a good plan to check with the EPA or your local building department before purchasing to ensure there’s no problem installing it in your area. Most lead roofing features a copper or other metal core and a lead coating to cut down on the weight without losing the insulation value of the material. Lead installs well on flat and highly pitched roofs, resists corrosion, and develops a deep and beautiful patina. It’s available in shingles or panels and has the benefit of being easy to bend or form against unusual shapes, so it’s ideal for curved roofs or tight fits. At $1,000 or more per square, it’s a luxury choice, but one that will stand the test of time.
Rusted Metal
A rusty metal roof probably doesn’t sound appealing at first, but this material isn’t disintegrating or full of holes—it’s made from a type of steel called Corten that is pre-weathered to have a uniform rusted color. The rust layer actually protects the steel core while looking charmingly rustic. It’s available in panels of various textures. This choice is not ideal for coastal areas; while the roof will repel water, snow, hail, and other weather, the blowing saltwater near the ocean will cause the rusted metal to deteriorate quickly.
Sheet Metal
Most of the material types are
