Metal Roofing vs. Asphalt Shingles: The Complete Comparison
Metal roofing and asphalt shingles differ most in three places: lifespan, upfront cost, and long-term value. A quality interlocking metal roof lasts 50 to 75 years, resists 120 mph winds, hail, and fire, and is never replaced for most homeowners — but it costs more to install. Asphalt shingles cost far less upfront and are simpler to repair, yet they wear out in 15 to 25 years and are replaced two to three times over the same period a single metal roof serves.
This guide compares both systems side by side — honestly, including where asphalt genuinely wins — so you can decide which is the smarter investment for your home and climate. If cost is your first question, our 30-year cost breakdown digs deeper into the numbers.
Quick Answer
Choose asphalt shingles for the lowest upfront cost, a short ownership horizon, or the simplest repairs. Choose metal roofing if you plan to stay long term, live where wind, hail, wildfire, or salt air punish a roof, or want the lowest lifetime cost, minimal maintenance, and better energy efficiency. Neither is wrong; they solve different problems.
The quick answer: which roof is right for you?
If you plan to stay in your home for more than about 12 to 15 years, or you live where wind, hail, wildfire, or salt air punish a roof, a premium metal roof usually wins on total cost of ownership and peace of mind. If your budget is tight, you expect to move within a few years, or you simply want the lowest possible upfront price, asphalt shingles are the sensible choice. Neither is wrong — they solve different problems.
- Pick asphalt for the lowest sticker price, a short ownership horizon, or the simplest repairs.
- Pick aluminum metal roofing for the longest lifespan, best storm and fire resilience, and lowest cost per year of service.

Metal roofing vs. asphalt shingles: the full side-by-side comparison
The table below compares the two systems across the nine factors homeowners weigh most. Figures reflect typical residential ranges; your quotes will vary by region, roof complexity, and product tier. See our testing reports for the performance ratings behind the metal column.
| Factor | Interlocking Aluminum Roof | Asphalt Shingles |
|---|---|---|
| Upfront cost (installed) | Higher — premium aluminum systems cost more per square foot | Lower — the most affordable mainstream option (asphalt wins here) |
| Lifespan | 50–75 years; often the last roof you buy | 15–25 years; typically replaced 2–3 times in the same span |
| Durability (wind / hail / fire) | Rated to 120 mph wind, UL 2218 Class 4 impact, and Class A (non-combustible) fire | Commonly 60–130 mph; granules dislodge under hail; Class A only with proper assembly |
| Weight | Very light — ~40–70 lbs per square; can often install over an existing roof | Heavy — ~250–350 lbs per square; adds structural load |
| Energy efficiency | Reflective cool-roof Alunar 70% PVDF finishes cut summer cooling costs | Absorbs heat; standard shingles offer limited reflectivity (cool-shingle options exist) |
| Maintenance | Minimal — occasional rinse and inspection; concealed fasteners don't back out | Simple, cheap spot repairs — individual shingles swap easily (asphalt wins here) |
| Appearance / options | Profiles that mimic slate, shake, tile, and shingle; durable colors that hold their finish | Familiar and widely available; 3-tab, architectural, and designer lines; colors fade over time |
| Resale value | Strong ROI and buyer appeal; a transferable Lifetime Warranty is a selling point | Solid, expected baseline; a new roof helps but is not a premium differentiator |
| Environmental impact | High recycled aluminum content and ~100% recyclable at end of life | Petroleum-based; roughly 13 million tons sent to U.S. landfills each year |
Where asphalt shingles genuinely win
We build metal roofs, but a fair comparison names the real strengths of the alternative:
- Lower upfront cost. Asphalt is the most affordable mainstream roofing material. If the first check is the deciding factor, shingles win outright.
- Simpler, cheaper repairs. A blown-off or cracked shingle can be swapped by almost any roofer with materials from any supply house. Metal repairs are far less frequent but can require a specialist and matching panels.
- Universal availability and familiarity. Every contractor installs asphalt, which keeps labor competitive and timelines short.
- Short-horizon economics. If you plan to sell within a few years, you may not stay long enough to capture metal's longevity payoff.
In short, if budget and timeline are tight, asphalt is a rational, honest choice — and there is no shame in it.
Where metal roofing pulls ahead
Metal's advantages compound over time and under stress:
- Lifespan and total cost of ownership. One metal roof commonly outlives two or three asphalt roofs, so metal often costs less per year despite the higher sticker price. See how long a metal roof lasts for the details.
- Storm and fire resilience. A 4-way interlock and concealed fasteners resist uplift to 120 mph; a UL 2218 Class 4 rating resists hail; and non-combustible metal earns Class A fire performance, which can lower insurance premiums in many regions.
- Light weight. Aluminum's ~40–70 lbs per square reduces structural stress and often allows installation over an existing roof, avoiding tear-off cost and landfill waste.
- Energy savings. Reflective Alunar 70% PVDF finishes push heat away, trimming cooling bills in hot and mixed climates.
- Sustainability and rust-proofing. Aluminum won't rust, uses high recycled content, and is roughly 100% recyclable — the greener end-of-life choice. For the full picture, weigh the pros and cons of a metal roof.
The cost picture over 30 years
Comparing sticker prices alone favors asphalt, but roofs are long-term assets. Consider a 30-year window. A homeowner who chooses asphalt will likely pay for a roof once now and again in roughly 18 to 22 years — two roofs, two tear-offs, two disposal bills, plus interim repairs. A homeowner who installs a premium metal roof pays more once and is typically done.
When you divide lifetime cost by years of service, the gap narrows dramatically and often flips in metal's favor. Add potential insurance discounts and energy savings, and the long-term math is why many owners describe metal as "the last roof I'll ever buy."

Which should you choose?
Choose asphalt shingles if your priority is the lowest upfront cost, you expect to move within a handful of years, or you want the simplest possible repairs. Choose metal roofing if you plan to stay long term, live in a storm-, hail-, wildfire-, or coastal-exposed area, want the lowest lifetime cost and maintenance, or care about energy efficiency and sustainability.

Metal roofing vs. asphalt shingles: frequently asked questions
Quick, honest answers to the questions homeowners ask most when weighing metal roofing against asphalt shingles.
Which lasts longer, metal roofing or asphalt shingles?
Metal roofing lasts far longer. A quality interlocking aluminum roof commonly lasts 50 to 75 years, while asphalt shingles typically last 15 to 25 years. Over a home's lifetime, one metal roof usually outlives two or three asphalt roofs.
Is metal roofing or asphalt cheaper?
Asphalt shingles are cheaper upfront and remain the most affordable mainstream roofing material. Over 30 years, however, metal is often cheaper per year because it isn't replaced two or three times and needs less maintenance. Our 30-year cost guide shows the full comparison.
Which roof is better for coastal or high-wind areas?
Metal roofing is generally the stronger choice for coastal and storm-prone areas. Interlocking aluminum panels with concealed fasteners resist wind uplift of 120 mph, and aluminum won't rust in salt air. Asphalt shingles are more likely to blow off or lose granules in severe wind and hail.
Which roof holds up best against hail and fire?
Metal typically wins both. Interlock aluminum panels carry a UL 2218 Class 4 impact rating, the highest hail rating available, and, being non-combustible, achieve Class A fire performance. Asphalt shingles can crack or lose protective granules under hail and only reach Class A with the correct assembly.
Can you install a metal roof over existing asphalt shingles?
Often, yes. Because aluminum is lightweight (about 40 to 70 lbs per square), a metal roof can frequently be installed over one existing layer of shingles where local codes allow, avoiding a costly tear-off and keeping old shingles out of the landfill. A contractor should first confirm the deck condition and code requirements.
Does a metal roof add more resale value than asphalt?
Yes. Metal roofing tends to deliver strong return on investment and stands out to buyers as a durable, low-maintenance, energy-efficient upgrade, and its transferable Lifetime Warranty is a selling point. A new asphalt roof helps a sale but is viewed as a baseline expectation rather than a premium feature.
Is a metal roof noisier than asphalt shingles in the rain?
No, not with a modern system. Interlocking metal roofs are installed over solid decking and underlayment, so they are comparably quiet to asphalt shingles in rain and hail. The 'loud barn roof' myth comes from bare metal panels over open framing.
Which roofing is more environmentally friendly?
Metal is the greener choice. Aluminum roofing uses high recycled content and is roughly 100% recyclable at end of life, while asphalt shingles are petroleum-based and contribute roughly 13 million tons of waste to U.S. landfills annually.
