Securing longevity with a metal roof

By Katelyn Bilicich, RoofSnap. 

Share the pros and cons of metal roofing with your customers and help them get the most out of their next roof replacement. 

Many homeowners are looking at metal roofs for their next replacement because of their durability and low maintenance costs. While a metal roof easily outlives an asphalt shingle roof, what is the true life of a metal roof and what maintenance is required? RoofSnap prepared a guide to help you answer these questions so your customers can get the most out of choosing and maintaining their metal roof. As a contractor, these tips can also help improve your service department, allowing you to provide maintenance and repair services in addition to the roof’s initial installation.  

How long do metal roofs last? 

Metal roofs can last anywhere from 40 to 80 years, making them a desirable choice for many customers.   

However, the longevity of a metal roof depends on several factors:   

Metal type   

The type of material used in a metal roof affects its lifespan. Customers should be aware of these options.  

• Steel: Commonly used for metal roofs, steel can last about 50 years. It’s durable and a popular choice among homeowners. 
• Aluminum: Aluminum is also a common roofing choice. It’s lighter than steel but offers the same lifespan — typically around 50 years. It’s also less prone to corrosion, making it a better choice in coastal areas.  
• Copper: Copper roofs can last over 70 years. But because of its higher cost, copper is most often used for special features rather than entire roofs.   
• Zinc: With a potential lifespan of over 100 years, zinc is extremely durable and requires minimal maintenance. It’s also becoming more popular in the U.S. and becoming easier to obtain.  

Weather conditions   

The local climate can impact how long a metal roof lasts.   

Areas with extreme weather — like heavy winds, hail or high UV exposure — can affect how long a roof lasts. Always recommend a metal type suited to your local climate.   

Installation quality   

Proper installation is crucial. If a roof isn’t installed correctly, it might have gaps or weak spots where water or wind can cause damage.   

A well-installed metal roof will outlast one that isn’t installed correctly in any situation. 

What are the pros and cons of metal roofs?  

Metal roofs are a great choice for many homes. But like anything else, they have their advantages and their drawbacks.   

It’s important to be familiar with both.   

Pros of metal roofs   

Here are some benefits of metal roofs:   

1 – Longevity: Metal roofs can last from 40 to 80 years. That’s much longer than the usual asphalt shingle roofs that last 15 to 20 years.   

2 – Durability: Metal roofs can take on tough weather. They can even stand up to winds as high as 140 miles per hour.   

3 – Aesthetics: Today’s metal roofs aren’t just strong. They’re also attractive. Your clients can pick from many more styles and colors than shingle or shake roofs offer. They’re sure to find an option that complements the architectural style of their home, whether contemporary or classic.   

4 – Sustainability: Metal roofs are kinder to the earth. They use a lot of recycled materials, which can be recycled again when it’s time to replace them. Plus, you can install them over the old roof as long as it’s in good repair. That means less waste.   

5 – Energy savings: Metal roofs can help keep homes cooler, which means your clients might pay less for air conditioning. They also make a good base for solar panels.   

6 – Safety: Metal roofs are usually given a Class A fire rating. This helps prevent and slow the spread of house fires. If the customer lives in an area prone to wildfire, the roof is a high-risk area of the home. Metal roofs can help mitigate some of that risk.

Cons of metal roofs   

The benefits are many, but there are also disadvantages. Given the lifespan of a metal roof, customers should also be aware of the cons before making a decision.  

1 – Higher up-front expense: Installing a metal roof usually costs more than other types. The price depends on roof size, metal type and labor.  

On average, a new metal roof might cost about $13,200 for 2000 square feet. But the price can vary widely, depending on the factors discussed above. Compare that to an average of $12,500 for the same size shingle roof, and the initial cost can be a little more of an investment.  

2 – Can get dents: Metal roofs are tough, certainly. But some options, like aluminum and copper, are more prone to dents from hail, falling branches and other debris.   

3 – Can be noisy: During a storm, you might hear the rain more on a metal roof than you would with shingles. But putting in the right insulation can help keep things quieter.   

4 – Corrosion: Particularly in coastal locations, some metal roofs might rust. But using materials like Galvalume steel, which mixes steel with aluminum and zinc, or straight aluminum can help stop rust.

What are the signs a metal roof needs to be replaced?   

When you’re checking out your customers’ homes, keep an eye out for these signs that might mean it’s time for a new metal roof:   

1 – Old age: Though metal roofs do last a long time, they don’t last forever. If a roof is getting close to the end of its expected lifespan, it might be time for a new one.   

2 – Leaks: If water is getting inside, it’s a surefire sign that the roof might need replacing. Check inside the house for water stains or drips, especially after it rains.   

3 – Weather damage: Storms can damage roofs. Look for dents, missing pieces or areas where the roof doesn’t look even anymore.   

4 – Flaking paint: If the paint on the metal roof is peeling or flaking off, it’s not just a cosmetic issue. It could mean the roof’s protective layer is wearing out.   

5 –Corrosion: Rust or corrosion is a sign that the metal is breaking down. This can lead to leaks and other problems.   

6 – Sagging: If parts of the roof look like they’re sagging or dipping, it’s a sign that the structure beneath might be weak or damaged.

Maintaining metal roofs for longevity   

Taking good care of metal roofs is key. That’s why offering roof maintenance can be a great service for your clients.   

It helps their roofs last longer and keeps their homes safe. Plus, it’s good for your business too.   

Here are some effective maintenance tasks:   

• Inspect the metal roof: Check the roof a few times a year. Look for any signs of trouble, like rust, dents, or loose or missing parts.  Doing this can help catch small issues before they snowball into big — and expensive — problems.   
• Clean surfaces: When you’ve completed your inspection, wash off dirt, leaves and other things that shouldn’t be there. Keeping the roof clean can stop a lot of problems from developing.   
• Repair damage fast: If you find any damage during the inspection, customers should be advised to have it fixed right away. Don’t delay. Repairs like sealing small leaks or fixing loose parts can make a big difference.  
• Clear debris: Inform customers that they need to keep debris cleared, just like they need to clean out gutters. They should make sure things like leaves and branches are not on the roof. They can hold water, and that’s not good for the roof. Keeping the roof clear also helps water run off like it should. Again, this may be an opportunity to offer them a maintenance package as an added value.
