What Problems Do Metal Roofs Have?

Metal roofs are a popular choice for homeowners and businesses. They last a long time, save energy, and give buildings a sleek, modern look. But no roofing material is perfect.



In this blog, we’ll take a closer look at common metal roof problems. Knowing these issues will help you make better decisions and keep your roof in great shape.

Common Problems with Metal Roofs

Metal roofs come with many benefits, but they also have their share of challenges. Here’s a breakdown of the most common issues and how to address them.

Oil Canning

Oil canning is the visible waviness or distortion in flat metal panels. It’s one of the most talked-about concerns with metal roofs.

• What causes oil canning?

Factors like thermal expansion, improper handling during installation, or overproduction of metal panels can lead to this issue.

• How to prevent it?

Using thicker metal, ribbed profiles, and hiring experienced professionals can reduce the chances of oil canning. Regular maintenance also helps minimize the risk.

Leaks

Leaks can happen with any roof, and metal roofs are no exception. While they’re highly durable, poor installation or damage can cause water to seep through.

• What causes leaks?

Loose fasteners, damaged seams, or improperly installed flashing are common culprits. Severe weather like hail or heavy winds can also lead to leaks.

• How to prevent leaks?

Schedule regular roof inspections to catch small issues before they become big problems. Always ensure proper installation by working with skilled contractors.

Corrosion

Although metal roofs are designed to resist corrosion, they’re not entirely immune to it.

• What causes corrosion?

Moisture, scratches on protective coatings, and the use of dissimilar metals can trigger corrosion.

• How to prevent corrosion?

Apply protective coatings, avoid mixing incompatible materials, and fix scratches quickly to keep rust at bay.

Scratching and Scuffing

Scratches and scuffs can compromise the appearance and longevity of your metal roof.

• What causes scratches and scuffing?

Improper handling during installation, falling debris, or regular foot traffic can create these blemishes.

• How to prevent it?

Use protective measures during installation and maintenance. For example, install guards or lay down padding when working on the roof.

Chalking and Fading

Over time, metal roofs can lose their vibrant color due to chalking and fading.

• What causes chalking and fading?

UV exposure, extreme weather, and aging paint systems can lead to these issues.

• How to prevent it?

Choose high-quality paint systems with UV-resistant coatings. Regularly cleaning and maintaining your roof also helps preserve its appearance.

Preventative Measures and Maintenance Tips

Taking care of a metal roof doesn’t have to be overwhelming. With proper maintenance and preventative measures, you can protect your investment and extend the life of your roof for decades.

Schedule Regular Inspections

Inspect your roof at least twice a year—ideally in the spring and fall—and after severe weather events like hailstorms or heavy winds.

During an inspection, look for:

• Loose or missing fasteners
  
  
• Signs of corrosion, like rust spots
  
  
• Damaged flashing or seams
  
  
• Areas where water may pool

If you’re not comfortable inspecting your roof, hire a professional roofing contractor. They can spot potential issues and recommend repairs before they become costly.

Clean Your Roof Regularly

Over time, dirt, debris, and mildew can collect on your roof, especially in shaded areas or where tree branches hang over. This buildup can lead to staining, moisture retention, or even mold growth.

To clean your roof:

• Use a soft-bristle brush or cloth and a mixture of mild detergent and water.
  
  
• Avoid using harsh chemicals or abrasive materials that could scratch the surface.
  
  
• Rinse thoroughly to remove all soap and residue.
  
  
• Regular cleaning not only keeps your roof looking great but also prevents small problems from turning into major headaches.
  
  

Use Compatible Materials

When making repairs or additions, always use materials that match your roof’s existing metal type. For example, mixing copper and aluminum can cause galvanic corrosion, which accelerates rusting and weakens the metal.

If you’re unsure about material compatibility, consult your roofing manufacturer or contractor to ensure repairs are done correctly.

Apply Protective Coatings

Protective coatings act as a shield against UV rays, moisture, and pollutants. These coatings can also improve your roof’s energy efficiency by reflecting sunlight, reducing heat absorption.

Key tips for applying protective coatings:

• Choose a product designed specifically for your metal roof type.
  
  
• Apply coatings in dry, moderate weather conditions to ensure proper adhesion.
  
  
• Reapply coatings as recommended by the manufacturer, typically every 5–10 years.

Protective coatings are an excellent investment to prolong your roof’s lifespan and maintain its appearance.

Ensure Proper Ventilation

Proper attic ventilation is critical for preventing problems like condensation, mold, and temperature imbalances. Without enough airflow, moisture can build up beneath your roof, leading to rust or even structural damage.

What to check for:

• Make sure soffit and ridge vents are clear of obstructions.
  
  
• Install additional vents if your attic consistently feels humid or hot.
  
  
• Work with a professional to evaluate whether your home’s ventilation is sufficient for your climate.

Good ventilation not only protects your metal roof but also reduces energy bills by keeping your home cooler in the summer and warmer in the winter.

Conclusion

Metal roofs are a great investment, combining durability, energy efficiency, and a sleek design. While they come with a few challenges like leaks, corrosion, and oil canning, these issues are manageable with proper care. Regular inspections, cleaning, and protective measures can extend the lifespan of your roof and keep it looking and performing its best for years.
