Metal Roof Maintenance 101: What You Should Know

Roof Maintenance

Roofs, often overlooked yet undeniably crucial components of any structure, serve as the first line of defense against nature's elements. From rain and snow to scorching sun and gusty winds, roofs shield homes and businesses, providing shelter and safety.

Among the various roofing options, metal roofs have become the go-to choice for many homeowners and businesses. Their appeal lies in their benefits, including durability, energy efficiency, and an aesthetically pleasing finish.

This article provides practical insights into preserving the functionality and longevity of metal roofs, ensuring that they continue to safeguard your property.

5 Metal Roof Maintenance Tips

Roof Maintenance

Regular Inspection

Regular inspections are crucial for maintaining the integrity of your metal roof. It is recommended to hire a professional roofer to conduct a thorough inspection at least twice a year – ideally in the spring and fall.

Roofers visually examine the entire roof surface for any signs of damage, such as dents, scratches, or loose seams. They pay close attention to areas around penetrations like vents, chimneys, and skylights, as these are common spots for potential issues.

They also check for accumulated debris like leaves and branches, which can trap moisture and lead to corrosion. They also inspect the gutters and downspouts to ensure proper drainage and prevent water buildup.

You can inspect the roof on your own, but there’s a chance that you might overlook subtle issues that a trained professional would catch. Hiring a professional roofer for these regular inspections ensures a comprehensive evaluation.


Regular cleaning is essential for preventing corrosion and maintaining the aesthetic appeal of your metal roof. Use a soft-bristle brush or a low-pressure power washer to remove dirt, algae, and other debris. Pay special attention to areas with stubborn stains, as they can contribute to corrosion over time.

Ensure the cleaning process is gentle to avoid damaging the protective coating on the metal. Also, avoid using abrasive materials or harsh chemicals that may compromise the roof's surface.

Regular cleaning not only enhances the roof's visual appearance but also promotes its longevity by preventing the buildup of corrosive substances.

You can clean the metal roof yourself, but hiring a professional is recommended to ensure thorough and effective removal of dirt, debris, and potential contaminants.

Rust Prevention and Treatment

Rust can be a significant concern for metal roofs, especially in areas with high humidity or coastal climates.

Apply a rust inhibitor or primer to any exposed metal surfaces to create a protective barrier against oxidation.

If rust is already present, it is advisable to hire a professional or address it promptly by removing the affected areas with a wire brush and applying a rust converter. Afterwards, apply rust-resistant paint to prevent further corrosion.

Regularly inspect and maintain the protective coating on your metal roof, as a compromised coating can leave the metal vulnerable to rust.

Sealant and Coating Inspection

The sealant and coating on your metal roof play a crucial role in protecting it from the elements. It is recommended to hire a professional or inspect these components regularly to ensure they remain intact and effective.

Look for any signs of cracking, peeling, or deterioration and address these issues promptly to prevent water infiltration.

Reapply sealant or coating as needed, especially after severe weather conditions like storms or if you notice any compromised areas. This proactive approach helps maintain the weather-resistant properties of the roof, preventing leaks and extending its lifespan.

Trimming Tree Branches 

Overhanging branches, especially during windy conditions, can scrape against the roof, leading to scratches that compromise the protective coating. These seemingly minor scratches create openings for rust and corrosion, impacting the long-term durability of the metal.

Additionally, close branches contribute to debris buildup on the roof. Leaves, pine needles, and other debris can accumulate, trapping moisture and fostering the growth of moss and algae. This moisture retention accelerates corrosion, posing a threat to the structural soundness of the metal.

Use proper trimming tools to ensure a clean cut without causing stress to the tree or leaving jagged edges that could damage the roof.

Taking Care of Your Metal Roof

Metal roofs offer several benefits, including enhanced durability, energy efficiency, and an extended lifespan. However, maintenance is necessary to ensure the roof continues to deliver on these advantages.

The following metal roof maintenance tips play a crucial role in preserving your roof's resilience and longevity:

  • Schedule professional inspections twice a year to catch potential issues early.
  • Regularly clean your metal roof to prevent corrosion and maintain its visual appeal.
  • Apply a rust inhibitor or primer to exposed metal surfaces and a layer of rust-resistant paint to prevent further damage.
  • Reapply sealant or coating if you see any signs like cracking and peeling. 
  • Trim overhanging branches to prevent scratches, debris buildup, and potential corrosion.
