Metal Roof vs Shingles: Complete Comparison
Metal roofing and asphalt shingles are the two most popular residential roofing options in America. While shingles have dominated for decades, metal roofing now accounts for 18% of the market and is growing fast. This guide compares every factor that matters so you can make an informed decision for your home.
Quick Comparison
| Factor | Metal Roof | Asphalt Shingles |
|---|---|---|
| Cost (installed) | $7-14/sq ft | $3.50-9/sq ft |
| Lifespan | 40-70 years | 15-30 years |
| Maintenance | Very low | Low-moderate |
| Wind resistance | Up to 140 mph | Up to 130 mph |
| Weight | 100-150 lbs/sq | 200-400 lbs/sq |
| Energy efficiency | Excellent | Good |
| Recyclable | 100% | Limited |
| Install over existing | Often possible | 1 layer only |
| Insurance discount | Often yes | IR shingles only |
Cost Comparison
Upfront Cost
Metal roofing costs 2-3 times more upfront than asphalt shingles. For a typical 2,000 sq ft roof:
- Asphalt shingles (architectural): $9,000-$14,000
- Standing seam metal: $16,000-$28,000
- Metal shingles: $14,000-$24,000

Lifetime Cost
The true cost picture changes dramatically over time. A metal roof lasting 50 years means one installation. During that same period, you would need 2-3 asphalt shingle roofs:
- Metal (50 years): $22,000 (one installation)
- Asphalt (50 years): $11,500 × 2 replacements = $23,000+, plus higher energy costs
When factoring in energy savings (metal can reduce cooling costs by 10-25%), insurance discounts, and zero replacement labor, metal roofing often costs less over a 40-50 year period.
Lifespan & Durability
Metal roofing typically lasts 40-70 years, with some premium copper or zinc roofs lasting 100+ years. The key durability advantages are:
- Does not crack, curl, or deteriorate from UV exposure like asphalt
- Impervious to algae, moss, and insect damage
- Does not absorb water
- Non-combustible (Class A fire rating)
Asphalt shingles last 15-30 years depending on the type. 3-tab shingles average 15-20 years, while architectural shingles last 25-30 years. The main lifespan factors are heat exposure, ventilation quality, and weather extremes.
Maintenance Requirements
Metal roofs require very little maintenance. An annual visual inspection and occasional cleaning of debris from valleys is typically all that is needed. Sealants around penetrations may need reapplication every 10-15 years.
Asphalt shingles need more attention. You should inspect for missing or damaged shingles after storms, clean algae and moss buildup (especially in humid climates), keep gutters clear, and replace individual damaged shingles as needed. Read our roof maintenance guide for a complete schedule.
Appearance & Style Options
Metal roofing comes in several profiles: standing seam (clean, modern lines), metal shingles (mimics traditional shingles), corrugated (agricultural/industrial aesthetic), and stone-coated steel (resembles tile or shakes). Metal is available in virtually any color and can complement both modern and traditional architecture.
Asphalt shingles offer the widest range of styles and colors. Architectural shingles provide a dimensional look, while luxury shingles replicate slate or wood. With hundreds of color options and blends, shingles can match any home style. See our guide to choosing roof color.
Energy Efficiency
Metal roofing reflects 25-70% of solar radiation, depending on color and coatings. Cool-metal roofing with reflective pigments can reduce cooling energy costs by 10-25%. This is particularly significant in hot climates like the southern United States.
Asphalt shingles absorb more heat, though light-colored and "cool roof" rated shingles have improved significantly. Energy Star-rated shingles reflect more solar energy than standard dark shingles but still cannot match metal's reflective performance.

Insurance Impact
Many insurance companies offer premium discounts for metal roofing due to its superior wind, fire, and impact resistance. Discounts typically range from 5-35% depending on the carrier and your location.
For asphalt shingles, insurance discounts are generally only available for Class 4 impact-resistant shingles. Standard asphalt shingles do not typically qualify for any premium reductions. See our roof insurance claims guide for more information.
Resale Value
Both materials add value, but the return on investment differs:
- Metal roofing: Recoups 60-85% of cost at resale. The remaining long lifespan is a major selling point for buyers.
- Asphalt shingles: Recoups 60-70% of cost. A new shingle roof is expected by buyers; it maintains value rather than adding premium value.
The Verdict: Which Should You Choose?
Choose asphalt shingles if:
- Budget is your primary constraint
- You plan to sell the home within 10 years
- Your HOA requires a specific shingle look
- You want the widest range of color and style options
Choose metal roofing if:
- You plan to stay in your home for 15+ years
- You live in a hurricane, hail, or wildfire-prone area
- Energy efficiency is a priority
- You want a low-maintenance, long-lasting solution
- You value sustainability and recyclability
Frequently Asked Questions
Is a metal roof louder than shingles during rain?
With proper underlayment and attic insulation, a metal roof is only marginally louder than shingles during rain - about 5-10 decibels more. Most homeowners report they cannot notice a difference. Metal roofs installed over solid sheathing with quality underlayment perform comparably to shingles acoustically.
Do metal roofs attract lightning?
No. Metal roofs do not attract lightning any more than other materials. In fact, metal roofing is safer during lightning strikes because it is non-combustible. The metal dissipates the charge across the entire roof surface. Lightning strikes are determined by location and height, not roofing material.
Can I install metal roofing over existing shingles?
In many cases, yes. Metal roofing is lightweight enough (100-150 lbs per square vs 200-400 for shingles) that it can be installed over one layer of existing shingles using furring strips. This saves the cost and hassle of tear-off. Check local building codes first.
Do metal roofs dent easily?
Quality metal roofing materials are rated for hail resistance. Steel and aluminum panels can dent from very large hail (2+ inches), but stone-coated steel and thicker gauge metals resist denting well. Any visible dents are cosmetic and do not affect the roof's waterproofing performance.
