Metal roofing has been growing in popularity among homeowners—and for good reason. It’s durable, energy-efficient, and built to handle everything from intense summer heat to heavy storms. But if you’re considering making the switch, you probably have some questions.

How long do metal roofs last? Are they noisy when it rains? Will they attract lightning? And what about the cost?

At RENCO Roofing, we’ve helped countless homeowners navigate their roofing options, and we know metal roofing comes with a lot of myths and misconceptions. That’s why we’ve put together this FAQ guide—to give you clear, straightforward answers so you can decide if a metal roof is right for your home.

Let’s dive into the most common questions and break down everything you need to know before making the investment.

Metal Roofing Benefits: What to Consider

If you’re considering a metal roof, you’re probably wondering what makes it worth the investment. While there are many benefits of metal roofing, its durability, efficiency, and minimal maintenance stand out.

Unlike traditional asphalt shingles, metal roofing is built to last and can handle just about anything Mother Nature throws its way. Let’s take a closer look at why more homeowners are choosing metal roofs.

Durability & Longevity

One of the biggest advantages of metal roofing is its impressive lifespan. While asphalt shingles typically last 20 to 30 years, a well-installed metal roof can last 40 to 70 years—sometimes even longer with proper maintenance. It’s designed to withstand:

Extreme heat and sun exposure – Perfect for Phoenix’s hot summers.
Heavy rain and monsoons – Water runs off quickly, reducing the risk of leaks.
High winds – Many metal roofs are rated for winds up to 140 mph.
Hail and impact resistance – Certain metals hold up better than traditional roofing materials.

Energy Efficiency & Savings

A metal roof does more than just protect your home—it can also help lower energy bills. Thanks to its reflective properties, metal roofing:

Reflects heat away from your home instead of absorbing it like asphalt shingles.
Reduces cooling costs, especially in hot climates like Arizona.
Provides better insulation options, helping with year-round energy efficiency.

This means your home stays cooler in the summer, leading to potential savings on your electricity bill.

Eco-Friendliness & Sustainability

If you’re looking for an environmentally friendly roofing option, metal is a great choice. Most metal roofing materials are made from recycled content, and at the end of their lifespan, they’re 100% recyclable—unlike asphalt shingles, which often end up in landfills.

Low Maintenance & Fire Resistance

Another big perk of metal roofs? Minimal upkeep. Unlike shingles that can crack or curl, metal roofs require very little maintenance over the years. Plus, metal is a non-combustible material, making it one of the best choices for fire protection—especially in areas prone to wildfires.

Now that we’ve covered the main metal roofing benefits, let’s talk about the cost. While metal roofs are an investment, they often pay off in the long run.

How Much Does a Metal Roof Cost?

One of the first questions homeowners ask about metal roofing is, “How much does it cost?” It’s true, metal roofs tend to have a higher upfront price than traditional shingles. But they also last much longer and require far less maintenance—making them a smart long-term investment.

Factors That Influence Cost

Several factors can impact the total price of your metal roof installation, including:

Type of metal – Steel and aluminum are the most common and affordable options, while copper and zinc tend to be more expensive.
Roof size and complexity – A larger or more complex roof (with multiple slopes, angles, or dormers) will increase labor and material costs.
Installation costs – Professional installation is crucial for long-term performance, and labor costs vary depending on location and roofing company.

Long-Term Cost Savings

While the initial cost of a metal roof is higher than asphalt shingles, the long-term savings often make up for it:

Lower maintenance and repair costs – Unlike shingles, metal doesn’t crack, warp, or require frequent repairs.
Energy efficiency – A reflective metal roof can significantly reduce cooling costs, especially in hot climates.
Increased home value – Metal roofing adds curb appeal and durability, making it an attractive feature for potential buyers.
Insurance discounts – Because of their fire resistance and durability, some homeowners qualify for lower insurance premiums with a metal roof.

So, while the upfront price is higher, a metal roof can actually save you money over time. Now that we’ve covered cost, let’s talk about the different types of metal roofing available and which might be the best fit for your home.

What Types of Metal Roofing Are Available?

Not all metal roofs look the same. Whether you’re aiming for a sleek, modern design or something that blends in with a traditional home, there’s a metal roofing style that fits your needs. Let’s break down the most common options.

Standing Seam Metal Roofs

Standing seam metal roofing is one of the most popular choices for homeowners looking for a clean, modern aesthetic. It features:

Raised seams and hidden fasteners, creating a smooth, streamlined appearance.
Exceptional durability, with strong resistance to leaks and weather damage.
Low maintenance, since there are fewer exposed screws that can loosen over time.

This style is commonly seen on contemporary homes and commercial buildings but works well on many home styles.

Metal Shingles vs. Corrugated Metal Panels

If you want the durability of metal but prefer the look of traditional roofing, metal shingles might be the best fit. These mimic the appearance of asphalt shingles, wood shakes, or even slate, while offering:

A more traditional aesthetic compared to standing seam.
Lightweight yet durable materials that can withstand extreme weather.
More color and texture options to match different home styles.

On the other hand, corrugated metal panels are a budget-friendly choice with an industrial or rustic look. These panels are:

Affordable compared to other metal roofing options.
Easy to install, making them popular for sheds, barns, and modern-style homes.
More exposed to wear and tear, since they use visible fasteners that may require maintenance over time.

Aluminum, Steel, Copper, and Zinc Roofing Options

The type of metal you choose impacts durability, appearance, and cost:

Steel – One of the most common choices, offering strength and affordability. Usually coated to prevent rust.
Aluminum – Lightweight, highly resistant to corrosion, and great for coastal areas.
Copper – A premium option that develops a beautiful patina over time but comes with a higher price tag.
Zinc – Extremely long-lasting and eco-friendly, but also one of the more expensive options.

With so many options, it’s easy to find a metal roofing style that fits your home’s design and your budget. Now, let’s address one of the most common questions homeowners have: Are metal roofs noisy when it rains?

Are Metal Roofs Noisy When It Rains?

In the Valley of the Sun, rain might not be an everyday concern—but when it does rain, it really rains. Monsoon storms roll in fast, bringing heavy downpours, strong winds, and that unmistakable desert scent of wet dirt. If you’re considering a metal roof, you might be wondering: Will it sound like a drum solo in my house every time it rains?

Myth vs. Reality

The idea that metal roofs are loud in the rain comes from images of raindrops hammering on tin sheds or old barns. But modern residential metal roofing is a completely different story. Thanks to insulation and proper underlayment, metal roofs are just as quiet—if not quieter—than asphalt shingles.

Underlayment absorbs sound, reducing noise levels inside your home.
Attic insulation further dampens sound, making rain barely noticeable.
Compared to tile or asphalt roofing, metal roofing produces a similar amount of sound inside the house.

How to Minimize Roof Noise Even Further

If you want to make sure your metal roof stays whisper-quiet during storms, here are a few extra measures:

Add more insulation – The thicker the insulation, the less noise you’ll hear.
Choose the right roof decking – A solid plywood base underneath the metal panels absorbs sound.
Opt for a textured metal finish – Some coatings help reduce vibrations, which can minimize sound.

So, while metal roofs can be noisy in an open-air barn, in a well-insulated home, you probably won’t notice much of a difference.

Do Metal Roofs Attract Lightning?

Arizona’s monsoon storms bring spectacular lightning displays, and it’s natural to wonder whether a metal roof increases the chances of a direct hit. After all, metal conducts electricity—but does that mean your home is more at risk?

Debunking the Lightning Myth

Despite the common belief, metal roofs do not attract lightning. In fact, they may actually make your home safer in the event of a lightning strike. Here’s why:

Lightning is drawn to the tallest object in an area, not necessarily metal. Trees, utility poles, and other structures are more likely to be struck.
Metal is non-combustible, meaning if lightning were to hit your roof, it wouldn’t ignite like a wood or asphalt roof might.
A metal roof disperses electricity safely, helping to reduce the risk of fire or major structural damage.

Additional Protection Against Storms

While metal roofing is naturally resistant to lightning-related issues, here are a few extra steps for maximum safety:

Properly grounding your home – A licensed electrician can ensure your home’s grounding system is up to code.
Impact-resistant materials – Metal roofs can handle hail and flying debris better than most other roofing options.
Regular inspections – Keeping your roof in top shape helps prevent storm-related damage.

So, while metal roofs don’t attract lightning, they can make your home more resilient against severe weather. Speaking of installation, let’s address another common question—can you install a metal roof over existing shingles?

Can You Install a Metal Roof Over Existing Shingles?

In some cases, a metal roof can be installed over existing shingles, eliminating the need for a tear-off. While this can save time and money, it’s not always the best option.

Pros & Cons of Installing Over Shingles

Pros:

Reduces labor costs and speeds up installation.
Provides an extra layer of insulation and soundproofing.

Cons:

Adds weight that could exceed structural limits.
Prevents full inspection of the decking, potentially hiding issues like leaks or rot.
It may not comply with local building codes.

When a Tear-Off Is Necessary

A full tear-off is recommended if:

The existing shingles are significantly damaged.
There are moisture issues, leaks, or rotting decking.
Local codes require complete removal before installing a new roof.

A professional inspection can determine the best approach for your home. Now, let’s take a look at how metal roofs help with energy efficiency, especially in Arizona’s extreme heat.

Are Metal Roofs Energy-Efficient?

With Arizona’s scorching summers, energy efficiency is a top concern for homeowners. A metal roof can help keep your home cooler and lower energy bills, thanks to its reflective properties and insulation benefits.

How Metal Roofing Reflects Heat

Unlike asphalt shingles, which absorb heat, metal roofs reflect the sun’s rays, reducing heat buildup in your attic. Many metal roofing materials come with cool roof coatings that enhance reflectivity, keeping indoor temperatures more stable and reducing reliance on air conditioning.

Best Metal Roofing Colors for Energy Efficiency

Lighter-colored metal roofs—such as white, beige, or light gray—reflect more heat than darker shades. However, modern reflective coatings allow even darker colors to offer energy-saving benefits.

With its ability to reduce cooling costs and improve overall energy efficiency, a metal roof is a smart choice for hot climates. Next, let’s take a look at how long metal roofs last compared to other roofing materials.

How Long Do Metal Roofs Last?

One of the biggest advantages of a metal roof is its lifespan. While traditional asphalt shingles need replacing every 20 to 30 years, a properly installed metal roof can last 40 to 70 years—sometimes even longer with the right maintenance.

Expected Lifespan Based on Material

Not all metal roofs are the same. Lifespan varies based on the type of metal used:

Steel – 40 to 60 years, depending on coating and maintenance.
Aluminum – 50+ years, with excellent corrosion resistance.
Copper & Zinc – 70+ years, developing a natural patina over time.

Maintenance Tips to Extend Roof Life

While metal roofs require less upkeep than shingles, routine maintenance helps maximize their lifespan:

Keep the roof clear of debris to prevent trapped moisture.
Check fasteners and sealants periodically for wear.
Address minor damage early before it leads to larger issues.

With its durability and minimal maintenance needs, a metal roof is a long-term investment in your home’s protection.

Do Metal Roofs Rust?

Rust is a common concern for homeowners considering a metal roof, but modern materials are designed to resist corrosion and stand up to the elements. While untreated metal can rust over time, most metal roofing products come with protective coatings that prevent this from happening.

Rust-Resistant Coatings & Treatments

To keep metal roofs in top shape, manufacturers use coatings that protect against moisture and oxidation:

Galvanized steel – Coated with a layer of zinc to prevent rust.
Galvalume steel – A mix of aluminum and zinc, offering superior corrosion resistance.
Powder-coated finishes – Provide extra protection and a variety of color options.

How to Prevent Rust & Corrosion

A properly installed and maintained metal roof is highly resistant to rust, but here are a few ways to extend its life even further:

Keep gutters and drainage areas clear to prevent standing water.
Avoid direct contact with incompatible materials like copper or treated wood, which can accelerate corrosion.
Schedule periodic inspections to check for scratches or worn coatings that may need touch-ups.

With the right materials and upkeep, rust is rarely an issue.

Do Metal Roofs Increase Home Value?

A new roof is always a solid investment, but a metal roof can add even more value to your home. Beyond just curb appeal, it offers long-term durability, energy efficiency, and potential insurance savings—all of which make your home more attractive to future buyers.

How a Metal Roof Impacts Resale Value

Homebuyers recognize the benefits of a roof that lasts decades with minimal upkeep. A metal roof can:

Increase resale value – Homes with metal roofing often sell for more than those with traditional shingles.
Attract eco-conscious buyers – Many buyers appreciate the sustainability and energy efficiency of metal roofing.
Offer a higher ROI – While metal roofs cost more upfront, their longevity and savings on maintenance can make them a better long-term investment.

Insurance Discounts for Metal Roofs

Because metal roofing is highly fire-resistant, impact-resistant, and durable, many insurance companies offer lower premiums for homes with metal roofs. If you’re replacing your roof, it’s worth checking with your insurer to see if you qualify for a discount.

Now that we’ve covered value, let’s address another common question—can you walk on a metal roof?

Can I Walk on a Metal Roof?

Unlike traditional shingles, metal roofing is smooth and can feel slippery underfoot, which raises concerns about whether it’s safe to walk on. While it is possible to walk on a metal roof, doing so requires caution to avoid damage and ensure personal safety.

Safety Tips for Walking on a Metal Roof

If you need to access your roof for maintenance or inspections, keep these precautions in mind:

Wear soft-soled shoes with good grip to prevent slipping.
Step on the raised portions of metal panels (for standing seam roofs) or near fasteners (for metal shingles) to avoid denting the material.
Avoid walking on wet or dusty surfaces, as metal roofs can become extremely slippery.
Use proper fall protection if working on a steep roof.

Alternative Inspection & Maintenance Methods

For safety, homeowners should limit walking on their roof whenever possible. Instead, consider:

Hiring a professional roofer to handle inspections and repairs.
Using drone inspections to check for damage without climbing onto the roof.

While metal roofs are strong and durable, improper foot traffic can cause dents or compromise protective coatings.

How Do You Maintain a Metal Roof?

One of the biggest advantages of a metal roof is that it requires less maintenance than traditional roofing materials. However, a little upkeep goes a long way in preserving its lifespan and performance.

Regular Maintenance Checklist

To keep your metal roof in the best condition, follow these simple maintenance steps:

Remove debris – Clear leaves, branches, and dirt to prevent moisture buildup.
Keep gutters clean – Clogged gutters can lead to water pooling near the roof’s edges.
Check for scratches or dents – Minor damage can be touched up with manufacturer-approved sealants or coatings.
Inspect fasteners and sealants – Over time, screws and seams may need tightening or resealing.

Seasonal Maintenance Tips

Your metal roof should hold up well year-round, but some extra attention during seasonal changes can help:

Before monsoon season – Check for loose panels and secure any potential weak spots.
During extreme heat – Look for expansion-related shifting and ensure venting is functioning properly.
In colder climates – Prevent ice buildup by keeping valleys and drainage areas clear.

With minimal effort, a metal roof can provide decades of reliable protection.
