Metal Roofing: Costs, Types, and What to Expect
By Jake Morrison, 8+ years in residential and commercial construction across Dallas and Fort Worth
·
A metal roof on a typical single family home runs $15,000 to $35,000 installed, against $8,000 to $20,000 for asphalt shingles. Metal costs roughly two to three times more upfront and lasts two to three times as long, 40 to 70 years versus 20 to 25.
Over a 30 year window the two land close together, because asphalt needs replacing once inside that window and metal does not. Metal wins outright on hail, wind, and cooling load. It loses on upfront cash, on low slope roofs, and on any building you plan to sell inside ten years.
Most metal roofing pages either sell you a roof or bury the number. This one gives you the arithmetic, shows where the figures come from, and tells you when metal is the wrong call.
- Metal runs $15,000 to $35,000 installed; asphalt runs $8,000 to $20,000.
- Over 30 years the gap narrows to roughly $3,000, because asphalt gets replaced once in that window and metal does not.
- Standing seam runs $10 to $18 per square foot and is the system most cost searches are actually about.
- Class 4 impact resistance is the highest rating under UL 2218, and it can qualify for an insurance discount in hail states, Texas included.
- Metal is the wrong call on roofs under a 3:12 pitch without a specialty system, on tight budgets, and on short holding periods.
What a metal roof costs
Installed cost depends on roof size, system type, deck condition, and how complex the roof is. Valleys, dormers, penetrations, and steep pitch all add labor. The range below reflects a typical single family home with a straightforward roof.
Contractors quote by the square. One square is 100 square feet of roof surface. Per square foot pricing is the cleanest way to compare systems, because it strips out the effect of roof size:
| System | Installed, per sq ft | 2,000 sq ft roof | Typical lifespan | Best for |
|---|---|---|---|---|
| Standing seam | $10 to $18 | $20,000 to $36,000 | 40 to 70 yrs | Long term ownership, modern exteriors, maximum weather resistance |
| Metal shingles | $7 to $14 | $14,000 to $28,000 | 40 to 60 yrs | Traditional appearance with metal performance |
| Corrugated / exposed fastener | $7 to $12 | $14,000 to $24,000 | 25 to 40 yrs | Outbuildings, barns, workshops, budget driven projects |
| Asphalt shingles | $4.50 to $8 | $9,000 to $16,000 | 20 to 25 yrs | Lowest upfront cost, short holding period |
Metal versus asphalt over 30 years
Upfront price is the wrong comparison, because the two systems are not replaced on the same schedule. A 30 year window is long enough to capture one asphalt replacement and short enough to stay realistic about how long people own buildings.
Two honest caveats on that chart. It uses midpoints, so a cheap asphalt job against an expensive metal job reverses the result. And it ignores the cost of money. $25,000 today is worth more than $14,000 today plus $14,000 in year 23. If you are financing, asphalt's advantage is larger than the bars suggest.
Either way, the sticker price gap overstates the lifetime gap by a wide margin.
Types of metal roofing
Standing seam
Vertical panels joined by raised seams, with fasteners concealed beneath the seam. No exposed screws means no exposed gaskets to dry out, which is why standing seam carries the longest warranties and the fewest leak complaints. At $10 to $18 per square foot installed it is the most expensive metal system, and it is what most people mean when they search for metal roof pricing.

Metal shingles
Stamped panels that mimic slate, tile, or wood shake while weighing a fraction as much. At $7 to $14 per square foot they sit between standing seam and corrugated, and they are the choice when a homeowners association or a historic district rules out the standing seam look. See metal roof shingles.
Corrugated and exposed fastener
Ribbed panels screwed directly through the face, $7 to $12 per square foot installed. Cheapest to buy and fastest to install, but the exposed neoprene washers degrade and typically need retorquing or replacement every 10 to 20 years. Common on barns, workshops, warehouses, and porch covers. Related: corrugated decking and corrugated steel decking.
Material choice underneath the profile
Galvanized steel, Galvalume, aluminum, copper, and zinc all behave differently on cost and corrosion. Aluminum resists salt air and suits coastal installations; steel is cheaper and stronger; copper and zinc are architectural grade and priced accordingly. Comparison: best metal roof types for durability and weather.
What drives the price up
| Factor | Effect on cost | Why |
|---|---|---|
| Roof size | Largest single driver | Priced per square (100 sq ft). Material and labor both scale directly. |
| Pitch | Steep roofs cost more | Above roughly 6:12, crews need staging and fall protection, slowing installation. |
| Complexity | Adds materially | Valleys, dormers, chimneys, and skylights each need custom flashing and cut panels. |
| Deck condition | Adds if rot is found | Rotted sheathing must be replaced before panels go down. See cost to replace roof decking. |
| Tear off | Adds, or avoided | Some jurisdictions allow metal over existing shingles. See installing over existing decking. |
| Gauge | Thicker costs more | 24 gauge is standard residential; 26 gauge is thinner and cheaper; 22 gauge is commercial. |
| Finish | PVDF costs more than SMP | PVDF (Kynar 500) resists chalk and fade far longer. See metal roof colors. |
| Insulation | Optional add | Affects both condensation control and cooling load. See metal roof insulation. |
The deck matters more than most owners expect. Panels are only as flat as what they sit on, and a soft deck telegraphs every dip through the finished roof. If your roof is old enough to need metal, budget for the possibility of deck work. Background: metal roof decking, decking thickness, and metal roofing without decking.
Lifespan and warranty
Read the warranty carefully. Manufacturers issue separate warranties for the substrate (the metal itself, against perforation) and the finish (against chalk, fade, and peel). A "50 year warranty" usually refers to the substrate. Finish warranties commonly run 25 to 35 years and are frequently prorated. Neither covers workmanship. Workmanship comes from the installer, and it is where most real world metal roof failures originate.
When leaks do appear on metal, they are almost always at fasteners, seams, or flashing rather than through the panel. See fixing a leaking metal roof and metal roof sealant.
When metal is the wrong choice
Most roofing pages skip this section. These are the cases where the honest answer is to pass on metal.
Below about 3:12, standard standing seam is not rated at all. You would need a mechanically seamed or specialty low slope system, which costs more and narrows your contractor pool. Below 2:12, most metal is off the table entirely.
Metal's advantage is amortized over decades, so a short holding period changes the math. Selling within ten years means paying the premium and handing the benefit to the buyer. Resale value recovers some of it, not all.
A tight budget with a failing roof is the other classic case. A well installed asphalt roof beats a cheap metal roof every time. If the choice is between quality asphalt and budget metal with exposed fasteners, take the asphalt.
Heavily shaded, debris loaded roofs are worth a pause too. Organic debris trapped against panel seams holds moisture. Manageable, but it means real maintenance rather than the install and forget pitch.
Check HOA and historic district rules before you buy. Metal shingles sometimes pass where standing seam does not.
If you are unsure whether your existing roof needs replacing at all, start with a roof inspection.
Regional cost variation
Installed pricing moves with local labor rates, permit costs, and code requirements far more than with material cost. The same standing seam roof can differ 30 to 40% between metro areas. California averages $10 to $16 per square foot, San Antonio $9 to $16.
In hail exposed states (Texas, Oklahoma, Colorado, Nebraska) the calculation shifts, because Class 4 impact resistance is the highest rating issued under UL 2218, and many carriers discount premiums for it. Metal roofing commonly achieves Class 4; asphalt tops out at Class 3 in most product lines. Over a 40 year roof life the premium discount is not a rounding error.
Discount amounts vary by carrier and by state, so confirm with your own insurer before counting on it. There is no universal rate. Texas owners: wind ratings matter alongside hail. Systems rated to 140 mph are available, against roughly 130 mph for typical architectural asphalt. Before filing anything, read what homeowners insurance covers on roof decking, hail damage roof repair, and the insurance payout guide.
Frequently asked questions
Standing seam runs $10 to $18 per square foot installed, roughly $20,000 to $36,000 on a 2,000 square foot roof. It sits at the top of the metal range because of concealed fastener labor and panel fabrication. Roof size, pitch, and complexity move the figure more than the panel choice does. Detail: standing seam metal roofing.
Forty to seventy years for a properly installed system, against 20 to 25 for asphalt shingles in hot, humid climates. Standing seam reaches the upper end; exposed fastener corrugated sits lower, at roughly 25 to 40 years, because the fastener washers degrade before the panels do.
Over a 30 year window the total cost difference is roughly $3,000 in favor of metal, because asphalt gets replaced once inside that window. Whether that is worth it depends on how long you are staying. Past about fifteen years of ownership, metal is usually the better financial decision. Under ten years, usually not.
Often yes, depending on deck condition and local building code. It saves the cost of tearing off the old roof and the landfill fees. It is a bad idea if the existing deck is soft or the shingle layers are uneven, because panels telegraph every irregularity underneath. Many jurisdictions cap total roofing layers at two. See installing over existing decking.
A reflective cool roof cuts cooling energy use by up to 15% according to the U.S. Department of Energy, with the largest savings in hot, sunny climates on buildings with poorly insulated attics. Manufacturer and trade association figures run higher, at 20 to 25%, but those are best case marketing claims rather than independent measurements. The saving comes from the reflective coating and the airspace beneath the panels. A dark metal roof with no reflective coating saves far less. Insulation choices matter as much as the panel.
Not on a residential installation. The noise reputation comes from barns and sheds where panels are fastened to open purlins with nothing beneath them. A house has solid decking, underlayment, insulation, and a ceiling between you and the panel. Indoors it sounds about the same as asphalt.
No. Lightning strikes the tallest conductive path to ground, which is governed by height and geometry, not roof material. Metal does not burn, so if a strike does occur, a metal roof is less likely to ignite than asphalt.
24 gauge is the residential standard for standing seam and the right default for most homes. 26 gauge is thinner and cheaper, acceptable for outbuildings and low exposure applications, but more prone to oil canning and denting. 22 gauge is heavier and generally commercial. Lower gauge number means thicker metal.
Yes, though a factory PVDF finish will outlast any field applied coating. Repainting is a legitimate way to extend a roof whose substrate is sound but whose finish has chalked. Full method: painting metal roofs.
