How to Care for Your Metal Roof

Metal roofing is an increasingly popular option for homeowners, thanks to its incredible durability and attractive appearance compared to other roofing types.

However, metal roofs, like any other type of roof, are susceptible to damage from severe weather conditions and lack of maintenance. Therefore a metal roof needs regular maintenance in order to keep it looking great and functioning properly.

Here are a few tips on how to care for your metal roof so it will last you for years to come:

Types of Metal Roof Maintenance

There are two things you need to know about maintaining the metal roof of your property. You need to maintain your roof on the outside and the inside. These are:

  • Surface maintenance of metal roofs
  • Structural maintenance of metal roofs

Let’s discuss each of these in more detail.

Surface Maintenance of Metal Roofs

Surface Maintenance of Metal Roofs

Surface maintenance includes tasks that can be performed without conducting a detailed inspection of the roofing structure. These include cleaning, inspection, and repair of any damage or corrosion on the roof.

While some homeowners or building owners may prefer to handle this maintenance themselves, you can always hire professional maintenance services. If you choose to undertake the maintenance by yourself, prioritizing your safety is crucial, mainly when dealing with steep slope roofs.

Roof maintenance varies depending on the environmental conditions, but we recommend it once a year or every 18 months.

Clean the Drains and Gutters

Gutters and drains should be cleared of leaves and debris at least once or twice a year. This can help prevent blockages, which could damage the roofing system and increase the risk of potential water leaks. Additionally, make sure to inspect the drainage systems periodically to ensure that they are working properly.

Inspect and Clean the Panels

Inspect and Clean the Panels

The metal panels should be inspected for broken, dented, and rusted areas. If you notice any defects, repairing or replacing them as soon as possible is important to avoid further damage. Additionally, dirt can accumulate on the surface of the roof over time, so it is recommended that you clean the panels at least once a year.

Clean the Dirt, Stains, Mildew, & Other Elements

Regularly cleaning your metal roof is crucial for preserving its lifespan and appearance. By removing dirt and potentially harmful elements that can accumulate on the surface, you can ensure the longevity and beauty of your roof. While this task may appear simple, it is vital to take the right precautions.

Remove Leaves and Debris Stuck in Dead Spots

Leaves and debris can accumulate in low spots or dead areas of the roof. This accumulation causes moisture to become trapped, which can lead to corrosion. Not only is debris stuck on a roof unsightly, but it can also cause damage to the metal’s paint system, leaving stains and scratches.

Remove Branches, Sticks, or Metal Touching the Roof Surface

Extra caution must be exercised when it comes to homes or buildings nestled under trees. It is crucial to ensure that no branches come into contact with or graze the metal roof’s surface.

Any such contact can potentially result in unsightly scratches or scuffs on the paint system. Also, ensure that there are no other metals or materials in contact with the roof. The interaction between other materials and a metal roof may cause premature degradation and staining of the roof.

Inspect the Roof For Scratches, Flaking, Chipping, Fading and Chalking

Like any surface with a paint system, metal roofing is susceptible to scratching, flaking, scuffing, chalking, and fading throughout its lifespan. It is crucial to promptly identify and address these issues to stop further damage.

Structural Maintenance of Metal Roofs

Structural maintenance is inspecting your roof’s components for any signs of corrosion or wear and tear. This requires experts and professional equipment to identify any problems properly.

It is important to note that performing a structural inspection as part of your regular roof maintenance routine can help you spot potential issues early on, thus preventing costly repairs in the future.

A recommended practice is to schedule professional structural maintenance at least once every two years.

Inspect and Repair Fasteners, Screws, and Rivets

Inspect and Repair Fasteners

The fasteners, screws, and rivets secure the panels onto the structure. These don’t require much upkeep as they tend to be extremely durable. However, it is crucial to regularly inspect these components to ensure they are secure, properly aligned, and not missing.

This becomes even more significant for exposed fastener roof systems, as the expansion and contraction of materials may cause the fasteners, screws, and rivets to loosen over time.

Fixing Loose or Separating Panel Seams

In addition to the fasteners, rivets, and screws, checking the panel seams is important. Loose or separating seam edges can lead to an increased risk of water intrusion, damaging your roofing system and causing leaks.

Examining Flashings and Perimeter Areas

Flashings, such as the ones around vents or chimneys, are an integral part of any metal roofing system. They can become compromised over time due to weather conditions and other factors, which is why it is important to inspect them for signs of damage regularly.

Checking and Replacing Sealant

How to Care for Your Metal Roof

Sealants are used to create a weather-tight seal on metal roofs, effectively keeping out water, dirt, wind, and other unwanted substances. This ensures that the metal roof remains as weather-tight as possible, maintaining its durability and protection.

Checking Areas Around Penetration Points

Penetration points like chimneys, air vents, skylights, and solar panels require specific flashing materials. Inspecting the deterioration of rubber flashings, like vent pipe boots, is crucial as UV rays gradually degrade the material.

Looking For Punctures From Falling Debris

Metal roofs are incredibly durable but can still be damaged by falling debris such as branches or hailstones. It is crucial to inspect the surface of your roof for any punctures or scratches that these impacts may have caused. If you do find punctures,


Regular metal roof maintenance is key to preserving its quality and ensuring that it protects your home or business for many years to come.
