Vinyl wins on lowest upfront cost and is the safe default in mild climates. Metal costs more but lasts far longer (40–60+ years vs 20–40), is noncombustible, and pays back over a long hold. The catch is that “metal” is two very different products: steel excels in hail and high wind but rusts in coastal salt air, while aluminum resists coastal corrosion but dents in hail.
The one-line rule: mild climate or tight budget → vinyl; hail, wildfire, or high wind and a long hold → steel; salt-air coastal → aluminum (but not in hail country). Matching the metal to your climate matters more than metal-vs-vinyl itself.
Metal siding costs more up front — so does its longer life, fire resistance, and hail performance actually pay off versus cheap vinyl? This guide compares vinyl and metal siding (steel and aluminum) head-to-head on installed cost, lifespan, fire, climate fit, maintenance, and appearance — with the sources behind each claim, and the two climate “traps” that catch most buyers.

Read it by climate. The fire and lifespan rows favor metal; the cost row favors vinyl; and the hail and coastal rows decide which metal. Those last two rows are where most metal projects go right or wrong.
🧱 What Each One Is
Vinyl (PVC)
Extruded polyvinyl-chloride panels with color molded through, hung loosely for thermal movement. It's the volume default — cheap, light, never needs paint. Quality vinyl is certified to ASTM D3679 (weatherability, wind load, and impact) through the Vinyl Siding Institute's program, third-party verified by Intertek; model codes require vinyl to meet D3679.
Steel
Galvanized or Galvalume-coated steel panels with a baked PVDF (Kynar) paint finish. The toughest common residential siding — best-in-class for hail and high wind, noncombustible, and long-lived. Its one weakness is coastal salt air, which attacks the cut edges and coating over time.
Aluminum
Lightweight aluminum panels, also PVDF-finished. Naturally corrosion-resistant, which makes it the coastal metal of choice, and noncombustible like steel. The trade-off is softness: aluminum dents easily, so it's a poor pick in hail country. It was the dominant metal siding before vinyl and is still common in coastal and mid-century homes.
🥊 Head-to-Head
Install Cost
Vinyl wins upfront. Installed, vinyl runs about $3.50–$9 per square foot(insulated vinyl higher), steel about $4–$12, and aluminum about $3–$14 — aluminum often prices near vinyl at the low end and climbs with premium profiles. On a typical 2,000 sq ft exterior that's roughly $7,000–$18,000 for vinyl versus $8,000–$24,000 for steel. Published sources disagree most on the top of the metal range (gauge, profile, and PVDF paint systems drive it) — full ranges are in the cost & planning section below.
🌦️ The two metal traps that catch most buyers
If you're leaning metal, the single most important decision is which metal — and two mismatches account for most regrets:
- Steel on the coast = rust. Steel is the toughest siding for hail and wind, but salt air corrodes it at cut edges and fasteners. Don't put bare/standard steel within a few miles of salt water — that's aluminum's job.
- Aluminum in hail country = dents. Aluminum shrugs off coastal salt but is soft; a hailstorm can leave a wall of dimples. In hail alley, steel (or impact-rated vinyl) is the play, not aluminum.
Bottom line: match the metal to your dominant climate risk. Get it right and metal outlives vinyl by decades; get it wrong and it fails faster than the vinyl you skipped.
Lifespan & Value
This is metal's core argument. Vinyl lasts 20–40 years; steel and aluminum reach 40–60+ years. On a cost-per-year basis that narrows — and often closes — the upfront gap, especially if you'll own the home a long time. Neither metal is separately benchmarked in the Cost vs. Value report (vinyl recoups 96.5% in the 2025 edition), so metal's case is longevity and durability rather than a published resale number.
Fire
Steel and aluminum are noncombustible — a real advantage in wildfire (WUI) zones. Vinyl is combustible: it softens, warps, and melts near heat, and can be restricted in the highest fire-hazard zones. If wildfire is a factor, metal (or fiber cement) beats vinyl outright here.
Climate Fit
- Hail / high wind: steel — the toughest of the three; vinyl cracks in cold and metal won't blow off like vinyl can.
- Coastal / salt air: aluminum — naturally corrosion-resistant; vinyl is also fine here, while steel is the wrong choice.
- Wildfire (WUI): steel or aluminum — noncombustible; vinyl is a liability.
- Cold: metal — vinyl gets brittle and can crack in extreme cold.
- Mild / moderate: vinyl — lowest cost with no real durability penalty.
Maintenance
Both are low-maintenance. Vinyl never needs paint — the color runs through the PVC — just an annual rinse. Metal's baked PVDF (Kynar) finish resists chalk and fade for decades, with chalk/fade warranties commonly 30–40 years; a repaint is possible but rarely needed for a long time. Metal can dent (aluminum especially) and steel can rust if the coating is breached, so touch up scratches.
Appearance
Vinyl offers the widest profile and color menu (clapboard, Dutch lap, shake, board & batten) but can read plastic and show seams. Metal delivers crisp, modern lines — standing-seam and board-and-batten metal are popular on contemporary and farmhouse designs — and holds bold, deep colors that vinyl can't (dark vinyl fades and warps). Metal is the more “architectural” look; vinyl is the more traditional, budget-friendly one.
🎯 Which Should You Choose?
- Upfront budget is the priority
- You're in a mild / moderate climate
- It's a rental or shorter hold
- You want the widest color/profile menu
- You're siding it yourself
- You're in hail or high-wind country
- Wildfire (WUI) resistance matters
- You'll hold the home long-term
- You want a modern, deep-color look
- You're not on the coast
- You're in a coastal / salt-air climate
- You want noncombustible siding
- You want a long lifespan, light weight
- You're not in hail country
- You're matching a mid-century home
The quick decision rule: start with budget and climate. Mild climate or tightest budget → vinyl. Long hold plus hail/wildfire/wind → steel. Salt-air coast → aluminum. And never cross the two traps: no steel on the coast, no aluminum in hail country.

❓ Frequently Asked Questions
Is metal siding worth it over vinyl?
If you'll own the home long-term or live in a harsh climate, often yes: metal lasts 40–60+ years versus 20–40 for vinyl, is noncombustible, and handles wind and (for steel) hail far better — which narrows the higher upfront cost on a per-year basis. In a mild climate or a short hold, vinyl's lower cost usually wins.
Steel or aluminum siding — which is better?
It depends entirely on climate. Steel is tougher and better for hail and high wind but rusts in coastal salt air. Aluminum resists coastal corrosion but dents easily, so it's poor in hail country. Pick steel inland (hail/wind/wildfire), aluminum on the coast.
How much more does metal cost than vinyl?
Roughly $1–$5 per square foot more at the middle of the range: vinyl runs about $3.50–$9/sq ft installed, steel about $4–$12, and aluminum about $3–$14. Gauge, profile, and the PVDF paint system drive the top of the metal range, and sources disagree there.
Does metal siding dent in hail?
Aluminum does — it's soft and can dimple in a hailstorm. Steel is much more hail-resistant and is the better metal for hail country. Vinyl can crack in cold-weather hail. If hail is your main risk, choose steel or an impact-rated product.
Will steel siding rust on the coast?
Standard steel can corrode in salt air, especially at cut edges and fasteners. Near salt water, aluminum (or vinyl) is the better choice. If you want steel on the coast, it needs a marine-grade coating and meticulous edge sealing — usually not worth the risk over aluminum.
Which lasts longer?
Metal — steel and aluminum reach 40–60+ years versus 20–40 for vinyl, and their PVDF finishes hold color for decades. Vinyl fades and can grow brittle before it fails outright.
Is vinyl or metal better for fire?
Metal — steel and aluminum are noncombustible, a genuine advantage in wildfire zones. Vinyl is combustible and melts near heat. For the highest fire-hazard areas, metal or fiber cement beats vinyl.
✅ Final Recommendation
There's no universal winner — it's a budget-and-climate call. Go vinyl for the lowest upfront cost in a mild climate, a rental, or a short hold. Go metal when longevity, fire resistance, or harsh-weather durability justify the higher price — and then match the metal to your climate: steel for hail, wind, and wildfire on a long hold; aluminum for salt-air coasts.
Above all, don't cross the two traps: no steel on the coast (it rusts) and no aluminum in hail country (it dents). Get the metal-to-climate match right and metal outlasts vinyl by decades; get it wrong and it fails faster than the vinyl you passed on.
