Benefits of metal roofing
Metal roofing offers a range of advantages that makes it appealing for both new construction and renovations:
Longevity
Metal roofs stand out for their remarkably long life and exceptional toughness. Most metal roofs last 30 to 80 years or more with proper installation and maintenance. This far exceeds traditional asphalt shingles, which likely need replacement every 15 to 30 years.
Durability
Metal roofs are built to withstand harsh conditions. They resist wind, hail, heavy snow, and even fire. Most metal roofs have:
Class 4 impact resistance rating, able to handle hail up to 2 inches in diameter
Class A fire rating, the highest level of fire resistance available for roofing materials
This makes them ideal for areas prone to storms or wildfires.
Energy efficiency
Energy efficiency is another major benefit that can reduce your utility bills. Metal roofs reflect solar heat rather than absorbing it, keeping your home cooler in summer. Many metal roofing materials can reduce cooling costs by up to 25%. They also provide good insulation during winter months, making them an energy-efficient choice year-round.
Eco-friendly
Metal roofs are highly sustainable, an appealing feature to the environmentally conscious homeowner. Most are made from 25% to 95% recycled materials and are fully recyclable at the end of their lifespan. This reduces construction waste and supports green building practices, while other roofing materials often end up in landfills.
Low maintenance
Once installed, metal roofs require little upkeep. Regular inspections and clearing debris are usually all that's needed. Their smooth surface prevents moss and algae growth, and minor repairs are rare, saving you time and money over the roof's lifetime.
Aesthetic appeal
Modern metal roofs come in diverse styles, colors, and finishes. You can choose panels that mimic shingles, tiles, or slate, blending seamlessly with your home's architecture. This versatility allows for unique design statements or more subtle integration.
Disadvantages of metal roofing
While metal roofing offers many benefits, it also has some drawbacks worth considering:
High initial cost
The biggest obstacle for many homeowners considering a metal roof is its expensive initial price tag. Metal roofing costs 2 to 4 times more than asphalt shingles up front. While you save on long-term maintenance and energy, the initial investment is steep compared to other options.
Prone to denting
Metal roofs, especially those made from softer metals like copper or aluminum, can dent from hail or falling branches. Steel roofs are more resistant but not immune to damage. In areas with frequent severe weather, denting can be a concern.
Noise
Rain and hail can be louder on a metal roof than on other roofing materials. Properly installed insulation and underlayment help dampen the noise, but some homeowners still notice the difference. Most people adjust over time, but it's a factor to consider if you're sensitive to sound.
Slipperiness
Wet or snowy metal roofs are slippery. This makes maintenance or repairs more hazardous. Snow guards can help prevent sudden snow slides, but extra caution is always needed when walking on metal roofs.
Color fading
Color fading and staining may occur on metal roofing over time. While modern metal roof coatings are more durable, some color fading is inevitable. Touch-up paint may not match perfectly, and color choices may be more limited than with other materials.
Expansion and contraction
Expansion and contraction can cause fasteners to loosen over time. Metal naturally expands and contracts with temperature changes, potentially leading to maintenance issues if not properly addressed during installation. This factor is another reason professional installation by an experienced contractor is so important.
Climate considerations for metal roofing
Your local climate plays a major role in determining whether metal roofing is the right choice for your home and which type will perform best.
Hot and sunny climates are where metal roofing truly shines. The reflective properties of metal roofs can reduce attic temperatures by 50 to 60 degrees compared to asphalt shingles. This translates to substantial cooling cost savings in areas like Arizona, Texas, and Florida. The cooling effect also reduces strain on HVAC systems and extends their life span.
Cold and snowy regions benefit from metal roofing's snow-shedding capabilities. The smooth surface and heat transfer properties help snow slide off naturally, reducing ice dam formation and structural load concerns. However, thermal expansion and contraction are more pronounced in areas with extreme temperature swings, so proper installation is critical.
Coastal and humid areas require careful material selection due to the salt and moisture in the air. Standard steel can rust, but aluminum, zinc, and galvanized steel with quality paint systems perform exceptionally well in these environments. Copper may develop patina more quickly in high-humidity environments.
Storm-prone regions, including tornado alleys and hurricane zones, benefit from metal roofing's superior wind resistance. Many metal roofs can withstand winds up to 140 mph when properly installed. Steel and aluminum roofs handle hail better than softer metals, making them ideal for areas with frequent severe storms.

Many HOAs have strict guidelines about roofing materials, colors, and styles to maintain neighborhood aesthetics. Before investing in metal roofing, review your HOA rules and restrictions and get written approval for your planned installation to avoid costly conflicts.
FAQs about metal roofing
How long does a metal roof last?
A metal roof lasts 30 to 80 years or more, depending on the material and installation quality. Premium materials like copper and zinc can last 80+ years. This exceptional longevity makes metal roofing one of the most durable roofing options available. Most manufacturers offer warranties ranging from 30 to 50 years, reflecting confidence in their products' durability.
Can you paint a metal roof?
Yes, you can paint a metal roof, but it requires proper preparation and high-quality paint designed for metal surfaces. The existing coating must be cleaned and possibly primed before applying new paint. Professional painting is best to ensure proper adhesion and longevity.
Can you put a metal roof over shingles?
In many cases, yes, you can install a metal roof over existing shingles, which can save on removal costs. However, this depends on local building codes, the condition of existing shingles, and structural considerations. Consult a qualified contractor to determine if this option is suitable for your specific situation.
Are metal roofs better than shingles?
Comparing metal roofing vs. asphalt shingles, asphalt costs significantly less while metal offers superior longevity, durability, and energy efficiency. While a metal roof costs more initially, the long-term value often makes it a better investment than shingles. However, "better" depends on your priorities, budget, and specific needs.
If longevity and low maintenance are priorities, metal roofing is better. If minimizing upfront costs is more important, asphalt shingles may be the better choice for your situation.
Do metal roofs attract lightning?
No, metal roofs do not attract lightning. This is a common misconception. Lightning will always strike the tallest thing around, no matter what it's made of. Metal roofing can actually be part of a lightning protection system when properly grounded. The non-combustible nature of metal provides additional safety compared to other roofing materials.
Does a metal roof increase home value?
Yes, metal roofs can increase home value. They are considered a premium feature and can make your home more attractive to buyers, especially in areas with harsh weather. The exact increase depends on your local market, the quality of installation, and the specific type of metal roofing chosen.
Getting estimates from metal roof companies
Metal roofs require specialized installation techniques and skilled contractors. If you've determined metal roofing is the best choice for your home, follow these guidelines to help you find a qualified metal roof installer near you:
Compare quotes from several reputable companies that have been in business for 5+ years.
Look for members of the Metal Roofing Alliance (MRA) and the National Roofing Contractors Association (NRCA).
Choose a company with a proven track record, specifically in metal roofing installation.
Verify contractor licenses, insurance, manufacturer certifications, and references.
