What Are Pros and Cons of Metal Roofing?
Metal roofing has become one of the most popular alternatives to traditional asphalt shingles. Homeowners, contractors, and property managers often choose it for its durability, energy efficiency, and modern appearance. However, like any roofing material, it comes with both advantages and disadvantages.
This guide covers the pros and cons of metal roofing to help you make an informed decision.
Advantages of Metal Roofing
Metal roofing has been shaking up the roofing world for a while now and not just because it’s loud during rain. People are choosing it for solid reasons.
1. Long Lifespan and Durability
Metal roofs are built to last. While asphalt shingles typically last 15–25 years, a properly installed metal roof can last 40–70 years. Premium metals like copper or zinc can even last over 100 years.
Resistant to cracking, shrinking, and erosion.
Withstand extreme weather, including heavy rain, strong winds, and hail.
Less prone to mold, mildew, and insect damage.
2. Wide Range of Styles and Finishes
Modern metal roofing is available in many styles, colors, and textures.
Can mimic slate, tile, or wood shake.
Available in standing seam panels, metal shingles, or tiles.
Enhances curb appeal with sleek, modern lines.
3. Energy Efficiency
Metal roofs reflect solar heat instead of absorbing it. This can reduce cooling costs by 10–25% in hot climates. Many options also include reflective coatings for better energy performance.
4. Fire Resistance
Unlike wood shingles, metal is non-combustible. Most metal roofing products have a Class A fire rating, offering maximum protection.

5. Low Maintenance
Metal roofing requires less maintenance than asphalt or wood.
No frequent replacements.
Resistant to algae growth.
Occasional inspections, debris removal, and checking fasteners are usually enough.

Disadvantages of Metal Roofs
So, metal roofing sounds like the superhero of the roofing world, right? Well, even superheroes have their bad days.
1. Higher Upfront Cost
Metal roofing costs more than asphalt shingles.
Asphalt shingles: $3–$6 per square foot.
Metal roofing: $7–$14 per square foot (depending on material).
Although the long lifespan offsets the cost, the initial investment can be significant.
2. Noise During Rain or Hail
Without proper insulation, metal roofs can be noisier during heavy rain or hailstorms. Adding underlayment or attic insulation reduces the noise but increases costs.
3. Risk of Dents and Damage
Here’s the honest truth hail can dent metal. It won’t usually cause leaks, but your once-smooth panels may end up looking like someone played whack-a-mole on your roof. In high-wind zones, poorly installed panels can even rip off. That’s rare but happens when contractors cut corners. And although the roof won’t burst into flames if lightning strikes, it still needs proper grounding. Just in case Thor decides to drop by.
4. Expansion and Contraction
Metal expands and contracts with temperature changes. If not installed correctly, this can cause fasteners to loosen or panels to warp. Professional installation is critical.
5. Slippery Surface
Metal roofs shed snow and water quickly. While this prevents buildup, it can create safety hazards. Snow guards or heating cables may be needed in colder climates.
6. Not Ideal for All Climates
Coastal areas: Saltwater exposure can corrode steel if not properly coated. Aluminum is better for coastal environments.
Heavy snow areas: Sudden snow slides can damage gutters or landscaping.
Metal Roof Maintenance: A Pro and a Con
On the pro side, metal roofs are incredibly low-maintenance compared to other roofing types like asphalt shingles or wood shakes. You won’t be replacing cracked shingles every few years or worrying about mold growth after a rainy season. Most metal roofs just need the occasional rinse and visual inspection to stay in great shape. That means fewer repairs, less hassle, and more peace of mind over the long haul.
But here’s the flip side: “low-maintenance” doesn’t mean “no-maintenance.”
You’ll still need to check for loose screws (especially on exposed fastener systems), worn sealant around flashings, and clear off any debris—like leaves, branches, or pine needles—that can trap moisture. Gutters need to be cleaned to prevent snow and water from backing up, and overhanging tree limbs should be trimmed to avoid scratching or denting the panels.
If you live in an area with heavy snowfall or lots of wind-driven debris (hello, Utah), you might need to keep a slightly closer eye on things. And walking on a metal roof isn’t something you want to try unless you know what you’re doing. These panels can dent under pressure, and slippery surfaces make DIY inspections risky. In many cases, you’ll want to hire a roofing pro for periodic inspections something we at Right Way Roofing are happy to help with.
So yes, metal roofs win major points for being less needy but they still deserve a little attention now and then. Stay on top of simple upkeep, and your metal roof will keep doing its job for decades.
Choosing the Right Metal Roof System for You
So, how do you know if a metal roof is your match or a mismatch?
Start with your budget. If you’re planning to stay in your home for decades, the investment makes sense. But if you’re moving in five years, shingles might be fine. Next, think about your local weather. Live somewhere hot? Go for light-colored, reflective panels. Snowy climate? Look into snow retention systems. Also, pick the right installer. Not every contractor knows how to work with metal. One wrong screw and the whole thing’s compromised.
Choose your metal type. Steel is strong, aluminum is rust-proof, copper is expensive but gorgeous, and zinc is low-maintenance but hard to find. Pick what fits your home not what the internet says is the “cool” option.
FAQs
Do Metal Roofs Attract Lightning?
Nope, they don’t. Metal doesn’t attract lightning; it just conducts it safely if it does strike. In fact, many fire departments prefer metal roofs for that reason.
Do Metal Roofs Attract Heat?
They reflect more heat than they absorb. Especially light-colored or coated metal roofs they bounce sunlight away like a tennis ball. However, dark metal? That’s another story. It’ll soak up more heat, just like black t-shirts in summer.
Do Metal Roofs Fade Over Time?
Eventually, yes but very slowly. With high-quality finishes like Kynar 500, the color stays bold for 30 years or more. Lower-end paints or uncoated metals may fade faster.
What Is the Biggest Problem With Metal Roofs?
It’s the cost. Plain and simple. Most complaints revolve around how pricey it is to install. After that, noise and storm dents take second and third place.
