Metal roofing costs 2–3× more upfront, but it lasts 40–70 years instead of 20–30. Over a 50-year period, the math often flips. Here's how to think through it.
Short answer: If you're staying in the home 15+ years, metal roofing is usually the better long-term investment. If you're planning to sell within 10 years or have a tight budget, asphalt shingles are the practical choice.
| Factor | Asphalt Shingles | Metal Roof |
|---|---|---|
| Cost (materials) | $100–$150/square | $300–$800/square |
| Cost (installed) | $350–$600/square | $600–$1,200/square |
| Lifespan | 20–30 years | 40–70 years |
| Weight | 2–4 lbs/sqft | 1–2 lbs/sqft |
| Wind resistance | 60–130 mph | 110–160 mph |
| Fire rating | Class A–C | Class A |
| Maintenance | Replace damaged shingles | Minimal |
| Insurance discount | Standard rates | 5–35% discount possible |
| Resale value | Standard | +1–6% home value |
| DIY-friendly | Yes (moderate skill) | No — specialized install |
| Rain noise | Quiet | Louder without solid decking |
| Snow performance | Can ice dam | Sheds snow well |
The simplest comparison: cost per year of roof life. Asphalt shingles at $500/square installed, lasting 25 years = $20/year. Metal at $900/square installed, lasting 50 years = $18/year. Metal wins — barely, and only over a long horizon.
But over 50 years, you'd replace asphalt shingles twice. That means two sets of labor and disposal costs, two rounds of disruption, two re-roofing projects. Metal eliminates one of those completely.
On a 20-square roof (2,000 sqft): asphalt installed twice over 50 years = roughly $14,000–$24,000 total. Metal installed once = $12,000–$24,000. At minimum cost, they're close. At mid-range, metal comes out ahead.
Planning to sell within 10 years. A new asphalt roof gets you the same buyer appeal as metal at half the cost. The 50-year math doesn't help you if you're handing the house to someone else in a decade.
Tight budget. Metal roofing requires significant upfront capital. A quality 30-year architectural shingle roof installed right is a perfectly good choice — it just needs replacing on schedule.
Simple roof geometry with easy access. Asphalt shingles are DIY-friendly on accessible roofs. Metal is not — it requires specialized equipment and skills to install correctly.
High wind areas with insurance maximums. In some hurricane zones, insurers set maximum payouts that don't account for metal's premium cost. Check what your policy covers before upgrading.
Long-term ownership. If you're staying 20+ years, metal's longevity advantage compounds. You avoid one full replacement cycle and all the disruption that comes with it.
Snow country. Metal sheds snow naturally — reducing ice dam risk and structural load. In areas with significant snowfall, this is a meaningful functional advantage.
Fire-prone regions. Metal is Class A fire-rated. In wildfire zones, this can matter for both safety and insurance. Some insurers won't write policies on homes with wood or lower-rated roofing in high-risk areas.
High winds. Standing seam metal can achieve ratings of 110–160 mph wind resistance — significantly higher than the 60–110 mph ratings of most asphalt shingles.
Hate maintenance. Metal roofs require essentially zero regular maintenance. Asphalt shingles need periodic inspection, granule loss monitoring, and individual shingle replacement after storms.
Metal installation: Requires specialized contractors — not every roofing company does standing seam metal. Get at least three bids. Installation quality matters enormously with metal; a poorly installed metal roof leaks at every fastener.
Asphalt replacement: When asphalt shingles hit the end of life, you're paying not just for new materials but for tear-off ($1–$2/sqft), disposal fees, and the disruption of a full re-roofing project.
Ice and water shield: Both roof types benefit from proper underlayment. Metal without a thermal break can cause condensation issues in cold climates — make sure your contractor uses appropriate underlayment for your region.
Over a 50-year horizon, metal roofing is usually cheaper than replacing asphalt shingles twice. Metal also provides better wind and fire resistance, lower maintenance, and potential insurance savings. If you plan to stay in the home 15+ years, the math often favors metal.
Metal roofing typically costs 2–3× more upfront: $600–$1,200 per square installed vs $350–$600 for asphalt. On a 2,000 sqft roof (20 squares), that's $12,000–$24,000 for metal vs $7,000–$12,000 for shingles.
Many insurers offer 5–35% discounts on homeowner's insurance premiums for metal roofs due to superior fire and wind resistance. The savings vary by insurer and location — call your insurance company for specifics before choosing your roofing material.
On exposed fastener or exposed metal panels without solid decking beneath, rain noise can be significant. Modern standing seam metal roofs installed over solid sheathing (with proper underlayment) are often no louder than asphalt shingles.
In most jurisdictions, yes — you can install metal over one layer of existing shingles. This saves tear-off costs ($1–$2 per sqft) and disposal fees. Check local code — some areas require tear-off, and you need to verify the structural load capacity.
Metal roofs actually shed snow and ice better than asphalt shingles due to their slick surface and thermal conductivity. Ice dams are less common on metal roofs. Snow guards may be needed to prevent large snow dumps from sliding off at once.
