Asphalt Shingles vs. Metal Roofing: A 25-Year Cost Analysis
Upfront cost, lifespan, insurance impact, and resale value — which actually wins long-term?
Asphalt is cheaper to install and easier to find contractors for; metal lasts 2–3× longer and qualifies for insurance discounts in storm-prone areas. The break-even is usually around year 22 — past that, metal wins on lifetime cost.
At a Glance
Asphalt Shingles
America's default roof — composite shingles in dozens of styles.
- Cost
- $5,500–12,000 (2,000 sq ft roof)
- Lifespan
- 20–25 years (architectural)
Pros
- Cheapest roofing material installed
- Every roofer can install it
- Wide style + color selection
- Easy spot repairs
Cons
- Shortest lifespan of major materials
- Granule loss over time
- Wind damage above 90 mph
- Not great for resale-conscious buyers
Standing-Seam Metal
Steel or aluminum panels with raised seams; 40–70 year life.
- Cost
- $14,000–28,000 (2,000 sq ft roof)
- Lifespan
- 40–70 years
Pros
- 2–3× the lifespan
- Up to Class 4 impact rating = insurance discount
- Reflects heat = cooling-bill savings
- 95% recyclable
- "Lifetime roof" resale story
Cons
- 2–2.5× upfront cost
- Fewer qualified installers
- Noisier in heavy rain (mitigated by attic insulation)
- Hail can dent (not pierce) softer metals

Bottom Line
Asphalt for short-term holds or tight budgets. Standing-seam metal for anyone staying 15+ years, especially in hail/hurricane zones — the insurance discount alone often closes a third of the cost gap, and you skip the next reroof entirely.
Frequently Asked Questions
Is metal roofing really worth 2–3× the cost?
If you're staying in the home 15+ years, almost always yes — you avoid a $10–18K reroof and likely qualify for an insurance discount worth $200–600/yr. If you're selling in <7 years, the math doesn't close.
Will metal hurt my home's resale?
In farmhouse, modern, and mountain styles it raises value; in dense traditional neighborhoods it can be neutral or slightly negative. Standing-seam reads more upscale than corrugated.
Does metal roofing make a house hot?
Opposite — most metal roofs are coated with "cool roof" pigments that reflect 30–60% more solar heat than asphalt, cutting attic temps 30°F+ and reducing AC costs.
Can I install metal over my existing asphalt roof?
Often yes — saves tear-off cost ($1–2/sq ft). Requires code-compliant underlayment and that the existing roof is single-layer and structurally sound.
