Aluminum roofing is a lightweight metal roof that will not rust, and it costs $7 to $18 per square foot installed, or $14,000 to $45,000 for most full replacements, per HomeGuide’s aluminum roofing cost guide (December 2025). Aluminum is sold by decimal thickness (.024, .032, .040 inch) rather than the steel gauge scale, and it comes as standing seam panels, interlocking shingles, stamped shakes, or corrugated panels.
The reason to pay more than galvanized steel ($5 to $13 per square foot in HomeGuide’s metal comparison) is salt. Englert’s sample U.S. roof warranty offers no warranty at all on prepainted or mill finish Galvalume within one-half mile of the seacoast, salt water, or brackish water, but still offers a 25-year paint warranty on prepainted aluminum in that zone (35 years farther inland). For a coastal or tidal-marsh home, that difference decides the roof.
How much does an aluminum roof cost in 2026?
An aluminum roof costs about $7 to $18 per square foot installed, or $14,000 to $45,000 for most homeowners, per HomeGuide’s December 2025 guide. Fixr’s aluminum roof guide (updated January 29, 2026) quotes a lower $4 to $12 per square foot and puts labor at 40% to 60% of the total. Material alone runs $3.50 to $6.50 per square foot in Western States Metal Roofing’s material price list. Aluminum standing seam sits at the higher end; corrugated panels and shingles run less.
Price moves with thickness, profile, and coating. A mechanically seamed .040 inch panel with a Kynar 500 (PVDF) finish costs more than a .024 inch exposed-fastener panel with a basic polyester paint, and HomeGuide adds $4 to $5 per square foot for underlayment, flashing, fasteners and trim when they are not already in the quote, plus $150 to $500 for permits.
| Aluminum roof type | Material per sq ft | Installed cost per sq ft | 2,500 sq ft roof, installed | Source |
|---|---|---|---|---|
| Screw-down / corrugated panel | $4 to $6 | $7 to $13 | $17,500 to $32,500 | HomeGuide, Dec 2025 |
| Interlocking shingles | $4 to $8 | $7 to $16 | $17,500 to $40,000 | HomeGuide, Dec 2025 |
| Standing seam | $5 to $10 | $10 to $18 | $25,000 to $45,000 | HomeGuide, Dec 2025 |
| Insulated panels | $12 to $14 | $17 to $21 | $42,500 to $52,500 | HomeGuide, Dec 2025 |
| Corrugated / shingles / standing seam (Fixr) | Not split out | $4 to $8 / $4 to $10 / $7 to $12 | $10,000 to $30,000 | Fixr, Jan 2026 |
The 2,500 square foot column multiplies each per-square-foot range by 2,500. Galvanized steel runs $5 to $13 per square foot installed in the same HomeGuide comparison, so aluminum’s premium is largest at the standing seam end. For a full cross-material breakdown, see our metal roof cost guide.
Aluminum roofing cost per square
Contractors usually quote metal roofs by the square, where one square equals 100 square feet. Multiplying HomeGuide’s December 2025 ranges by 100, an installed aluminum roof runs about $700 to $1,800 per square, and up to $2,100 per square for insulated panels. Corrugated panels sit near the bottom, standing seam near the top, and shingles and shakes in between.
| Aluminum profile | Installed cost per square (100 sq ft) | Material per square | Notes |
|---|---|---|---|
| Corrugated / exposed-fastener panel | $700 to $1,300 | $400 to $600 | Lowest cost, screw-through fasteners |
| Aluminum shingles and shakes | $700 to $1,600 | $400 to $800 | Four-way interlock, slate, shake or tile looks |
| Standing seam | $1,000 to $1,800 | $500 to $1,000 | Hidden clips, coastal and long-run standard |
| Insulated standing seam panels | $1,700 to $2,100 | $1,200 to $1,400 | Foam core between aluminum skins |

Aluminum roofing decision table
| If your home or roof has | Then | Rule source |
|---|---|---|
| Location within one-half mile of seacoast, salt or brackish water | Price aluminum; Englert offers no Galvalume warranty there, and a 25-year (not 35-year) paint warranty on prepainted aluminum | Englert sample U.S. roof warranty (2/2021) |
| Location 1,500 ft or less from salt water, or in sea spray | Expect some Galvalume finish warranties to be void; JD Metals’ 25-year Galvalume warranty excludes this zone | JD Metals Galvalume warranty |
| Inland site in a frequent-hail area | Steel resists denting better at the same thickness; if you choose aluminum, specify .040 inch | HomeGuide: hail areas may need thicker aluminum panels |
| Slope from 1/2:12 up to 2:12 | Use a mechanically seamed panel (Petersen Tite-Loc, Tite-Loc Plus or PAC-150 double lock are evaluated to 1/2:12) | ICC-ES ESR-4173, Table 3 |
| Slope 2:12 or steeper | Snap-lock standing seam (Petersen Snap-Clad minimum 2:12) or shingles become options | ICC-ES ESR-4173, Table 3 |
| Slope flatter than 1/4:12 | Use a low-slope membrane; Englert’s paint warranty does not apply below 1/4:12 | Englert sample U.S. roof warranty |
| Copper or lead flashing, piping or runoff onto the roof | Isolate or reroute it; Englert excludes areas with runoff from or contact with lead or copper | Englert sample U.S. roof warranty |
| Dormers, hips and valleys on a cut-up roof | Interlocking aluminum shingles ($7 to $16 per sq ft installed) waste less than long panels | HomeGuide, Dec 2025 |
Types of aluminum roofing: standing seam, shingles, and shakes
Aluminum roofing comes in four main forms, priced by HomeGuide (December 2025) at $10 to $18 per square foot installed for standing seam, $7 to $16 for interlocking shingles, $7 to $13 for corrugated screw-down panels, and $17 to $21 for insulated panels. Standing seam hides its fasteners under raised seams and sheds water best; shingles and shakes stamp aluminum into slate, tile, or cedar-shake looks that suit complex rooflines; corrugated panels are the budget, screw-through option common on outbuildings. All four resist red rust equally because the metal contains no iron.
Aluminum shakes are pressed to mimic split cedar shakes while weighing well under a pound per square foot of metal (see the thickness table below). Fire class for metal roofs is an assembly rating to ASTM E108 or UL 790: Petersen’s aluminum panels, for example, reach Class A in ESR-4173 only over the listed barrier board or deck, so ask for the listed assembly for any aluminum shake. Zappone’s aluminum shingle, a four-way interlocking shingle nailed directly to the deck, carries a 50-year transferable warranty per Zappone’s product page. The same corrosion-proof aluminum stock also forms exterior metal wall panels and metal siding panels, so a coastal home can carry one metal across roof and walls.

Aluminum vs steel roofing: which is right for your home?
Aluminum wins on corrosion resistance and weight; steel wins on price and dent resistance. Aluminum will not rust, so it is the better metal within Englert’s one-half mile salt-water zone, where Englert offers no Galvalume warranty. Steel is harder and costs $5 to $13 per square foot installed versus $7 to $18 for aluminum in HomeGuide’s guides, so it makes sense inland where corrosion is not the main threat and hail or falling debris is.
Steel is the stiffer, harder metal, so a steel panel resists denting from hail and foot traffic better than aluminum of the same thickness. Aluminum’s density is about one-third of steel’s (about 2.7 g/cm3, per Kloeckner Metals), which eases handling and reduces structural load, but it dings more easily. Residential steel panels typically run 24 to 29 gauge per Englert’s steel and aluminum explainer.
| Factor | Aluminum | Steel (galvanized / Galvalume) | Source |
|---|---|---|---|
| Rust resistance | No iron to rust; no metallic coating needed | Relies on zinc or Galvalume coating | Englert explainer |
| Warranty within one-half mile of salt water | 25-year paint warranty (prepainted aluminum) | No warranty on Galvalume | Englert sample warranty |
| Density | About 2.7 g/cm3 (about 1/3 of steel) | About 3 times aluminum | Kloeckner Metals |
| Dent resistance | Lower (softer metal) | Higher | HomeGuide aluminum guide |
| Cost per sq ft installed | $7 to $18 | $5 to $13 (galvanized) | HomeGuide aluminum and zinc roof guides |
| Typical lifespan or warranty | 40 to 60+ years lifespan | Galvalume substrate warranty 20 years (AZ50) or 25 years (AZ55) inland | HomeGuide; Englert sample warranty |

Why aluminum beats steel on the coast
Aluminum is the standard coastal metal roof because it does not corrode in salt air the way coated steel does. When aluminum is exposed to oxygen it forms a thin, tight aluminum-oxide layer that seals the surface and re-forms if scratched, and there is no iron to rust. Steel and Galvalume rely on a sacrificial zinc-based coating that salt slowly consumes, especially at cut edges and fastener holes, which is why Englert’s warranty drops Galvalume coverage entirely within one-half mile of salt or brackish water. Petersen’s PAC-CLAD catalog goes further for coastal jobs: its finish warranty requires aluminum panels with stainless steel clips. For aluminum vs Galvalume cost near the Florida coast, see our Florida metal roof cost guide.
If the home sits within one-half mile of the ocean, an intracoastal waterway, or a salt marsh, ask the panel maker in writing whether its steel or Galvalume warranty covers that address (Englert’s does not; JD Metals excludes 1,500 feet or less), and price aluminum as the alternative. More than one-half mile inland, steel or Galvalume is usually the lower-cost choice.
Watch galvanic corrosion. Pairing aluminum with dissimilar metals like copper roofing, or using standard steel fasteners, can trigger galvanic corrosion where the two metals meet in the presence of salt moisture, and Englert’s finish warranty excludes areas with runoff from or contact with lead or copper. Use aluminum or coated stainless fasteners and keep aluminum isolated from copper flashing and gutters. If you are matching rainware to the roof, our steel vs aluminum gutters comparison weighs the same corrosion trade-offs.
Aluminum roofing thickness: why it is not measured in gauge
Aluminum is specified in decimal inches, not the gauge numbers used for steel, so panels are called out as .024, .032, or .040 inch. Thicker aluminum resists oil canning and denting but costs more. ICC-ES ESR-4173 (reissued September 2025) requires ASTM B209 aluminum at least 0.032 inch thick for Petersen’s evaluated standing seam panels, and Petersen’s Tite-Loc panels are offered in .032 and .040 aluminum in lengths up to 64 feet, per the PAC-CLAD catalog.
Common minimums: exposed-fastener aluminum panels start around .024 inch, and aluminum standing seam should be at least .032 inch, matching the ESR-4173 floor, with .040 inch preferred for wide pans, high-wind coasts, and hail areas, where HomeGuide notes thicker panels may be needed.
| Aluminum thickness | Sheet weight per sq ft (per square) | Typical use | Source |
|---|---|---|---|
| .019 in | 0.27 lb (27 lb) | Light-duty panels, some shingles; budget tier, more prone to oil canning | Editorial guideline |
| .024 in | 0.34 lb (34 lb) | Exposed-fastener corrugated or ribbed panels | Editorial guideline |
| .032 in | 0.45 lb (45 lb) | Standing seam minimum | ICC-ES ESR-4173 |
| .040 in | 0.56 lb (56 lb) | Premium standing seam, wide pans, high wind, hail | Petersen Tite-Loc offering |
Weights are calculated as thickness x 0.0975 lb per cubic inch (2.70 g/cm3) x 144 square inches, sheet metal only, before seams and laps. If you are comparing gauge across metals, our metal roofing types overview lines up panels, profiles, and metals side by side.
Aluminum shingles vs aluminum standing seam
Aluminum comes in two main residential forms: standing seam panels with hidden fasteners and raised interlocking seams ($10 to $18 per square foot installed per HomeGuide), and aluminum shingles that mimic slate, shake, or tile and lock together on all four edges ($7 to $16). Mechanically seamed standing seam is evaluated down to 1/2:12 in ESR-4173; shingles handle complex rooflines and steep, cut-up roofs where long panels waste material.
Standing seam is the premium choice for wind and water performance because nothing penetrates the panel face; Petersen’s snap-on panels run up to 35 feet long with a 35-year non-prorated finish warranty available, per PAC-CLAD. Aluminum shingles trade some of that for design flexibility and easier work around dormers, hips, and valleys. HomeGuide puts aluminum roof lifespan at 40 to 60+ years with proper installation.
- Aluminum standing seam: hidden clips, best water shedding, cleanest look, $10 to $18 per sq ft installed, ideal on coasts and long straight runs.
- Aluminum shingles: four-way interlock, slate or shake looks, better for complex roofs, $7 to $16 per sq ft installed, more seams.
Pros and cons of aluminum roofing
Aluminum’s core advantage is corrosion resistance at low weight; its main drawbacks are cost and softness. It is one of the more sustainable roofing metals: Zappone notes that 75 percent of the aluminum produced over the last 100 years is still in use, and HomeGuide lists aluminum roofing as fully recyclable at end of life. HomeGuide also puts aluminum at 2 to 3 times the cost of asphalt shingles.
- Pros: will not rust, density about one-third of steel, 40 to 60+ year lifespan (HomeGuide), 25-year paint warranty available even within one-half mile of salt water (Englert), recyclable, low structural load.
- Cons: $7 to $18 per sq ft installed versus $5 to $13 for galvanized steel (HomeGuide), dents more easily, can oil-can in thin gauges, expands and contracts more (needs proper clip and fastener detailing), risk of galvanic corrosion if paired with copper or steel hardware.

How long does an aluminum roof last?
An aluminum roof lasts 40 to 60+ years with proper installation and maintenance, per HomeGuide, and it keeps its metal warranty in coastal settings where Galvalume warranties end. Because there is no rust to undermine the metal, the practical limits are the paint finish, the fasteners, and the seam or clip system rather than the aluminum itself. Englert’s 70% Kynar 500 / Hylar 5000 finish carries a 35-year limited warranty inland (25 years within one-half mile of salt water). Our roof lifespan by material report sets those numbers against asphalt, tile, and other systems.
Lifespan depends on thickness, finish quality, and detailing. A .032 or .040 inch standing seam roof with a PVDF finish and stainless or aluminum fasteners outlasts a thin exposed-fastener panel with a polyester paint, whose exposed screws and washers are the first wear points; HomeGuide recommends inspecting an aluminum roof at least twice a year. Englert’s paint warranty defines failure as chalking worse than a rating of 8 (ASTM D4214) or fading more than 5 E units (ASTM D2244). When a factory finish finally chalks, a field-applied aluminum roof coating can extend service life rather than forcing a tear-off.
Aluminum roofing: frequently asked questions
Is aluminum roofing better than steel?
Aluminum is better for coastal homes because it will not rust, and Englert offers no Galvalume warranty within one-half mile of salt water. Steel is better inland, where its lower price ($5 to $13 per square foot installed for galvanized versus $7 to $18 for aluminum, per HomeGuide) and stronger dent resistance matter more.
How much does an aluminum roof cost?
An aluminum roof costs about $7 to $18 per square foot installed, or $14,000 to $45,000 for most homeowners, per HomeGuide (December 2025). Fixr quotes $4 to $12 per square foot (January 2026). Standing seam sits at the high end, at $10 to $18, while corrugated panels and aluminum shingles cost less.
How much does aluminum roofing cost per square?
In per-square terms (one square equals 100 square feet), installed aluminum roofing runs about $700 to $1,800 based on HomeGuide’s December 2025 ranges. Corrugated panels run $700 to $1,300, shingles $700 to $1,600, standing seam $1,000 to $1,800, and insulated panels $1,700 to $2,100 per square.
Why is aluminum used for coastal roofs?
Aluminum forms a self-healing oxide layer that seals its surface, so salt air cannot rust it. Steel and Galvalume rely on a zinc-based coating that salt slowly consumes at cut edges and fasteners. Englert offers no Galvalume warranty within one-half mile of salt or brackish water but still warrants prepainted aluminum paint for 25 years there.
What thickness should an aluminum roof be?
Aluminum is measured in decimal inches, not steel gauge. Exposed-fastener panels start around .024 inch, aluminum standing seam should be at least .032 inch (the minimum in ICC-ES ESR-4173), and .040 inch is preferred for wide pans, high-wind coasts, and hail areas.
How long does an aluminum roof last?
An aluminum roof lasts 40 to 60+ years with proper installation and maintenance, per HomeGuide. Because there is no rust, lifespan is limited by the paint finish, fasteners, and seam system. Englert’s PVDF (Kynar 500) finish carries a 35-year limited warranty, or 25 years within one-half mile of salt water.
