How Do You Restore A Damaged Metal Roof?

Key Takeaways:

  • Metal roofs offer long-term durability and protection against the elements.
  • There are five common metal roof types: aluminum, copper, steel, tin, and zinc.
  • Extreme weather conditions, exposure to moisture, and airborne contaminants can cause corrosion on metal roofs, leading to roof leaks and other problems.
  • You can restore metal roofs using one of these methods: flute-fill and membrane roof over, hat channel method, retro-R panel, and silicon coatings.
  • Each method has its advantages and disadvantages, so choose wisely based on the type of metal roof you have.
  • JB Commercial Roofing LLC offers a premier metal roof restoration system to restore the metal roof and protect it from the elements.

Living in Ohio, we’re all too familiar with the harsh weather conditions that can take a toll on our properties, especially our roofs. From severe storms and hail damage to regular wear and tear over time, if any material could withstand the test of time – it is metal.

Metal roofs are highly durable and require less maintenance than other roofing materials. They also have the most extended lifespan of any roofing material, lasting up to 50 years without any major repairs needed. Moreover, metal roofs resist fire, wind, rain, and hail damage. They also reflect heat from the sun better than asphalt roofs, making them more energy efficient.

Metal roofs require occasional maintenance and repair despite their impressive longevity and durability. Even the strongest metals can succumb to the elements, and regular checks are necessary to keep your metal roof in top condition.

Types of Metal Roofs

· Aluminum

Aluminum is a lightweight, rust-resistant material often used for residential metal roofs. It can be painted in any color to match the aesthetic of your home. Aluminum is also an energy-efficient material, reflecting heat from the sun and keeping your house cool in the summer months.


· Copper

Copper roofs are among the most durable and reliable metal roofing materials. They require minimal upkeep, and copper can last up to 100 years. Copper is also an environmentally friendly choice, as it’s fully recyclable and retains its strength and durability no matter how many times it’s recycled.

· Steel

Steel is another popular choice for metal roofs and is available in several different varieties. It can be galvanized – a zinc coating that helps protect against rust and corrosion – or coated with a color-bond finish, which adds extra protection and a decorative finish.

Steel is strong, lightweight, and easy to install. It’s also relatively low maintenance and affordable compared to other roofing materials.

· Tin

Tin is an affordable and durable metal roofing material that is no longer used as much as it once was. It’s easy to work with and requires no special tools or equipment. Tin is very lightweight, making it a good choice for lightweight roof designs.

However, it is prone to rust and is less energy-efficient than other materials. Additionally, rain on a tin roof can be loud.

· Zinc

Zinc is a popular metal roofing material due to its durability and low maintenance. It also has optimal fire resistance, prevents mold and mildew, and is corrosion-resistant. While it can be expensive to install, zinc lasts for several decades if properly cared for. 

Elements That Damage Metal Roofs

The most common issue with metal roofs is rust and corrosion. It is caused by exposure to moisture, which can happen when the roof is not sealed correctly, and water gets in. Additionally, extreme weather conditions and airborne contaminants can also cause metal roofs to corrode.

To prevent this, it’s crucial to ensure that your metal roof is adequately sealed and regularly maintained. Regular inspections can identify any potential issues that need to be addressed before they become too severe.

Metal Roof Restoration – 4 Ways to Restore Metal Roof

1. Flute-Fill and Membrane Roof Over:

Whether your roof has an exposed fastener or R-panel and standing seam, this is the method for you. The procedure consists of laying a membrane across the existing roof, then filling in flutes with a sealant material that forms a continuous membrane over the entire roofing system.

It is an ideal roof restoration method since it offers superior protection against water intrusion while maintaining the existing metal roof.


  • Increases energy efficiency
  • Creates a continuous watertight seal
  • Doesn’t require insulation removal to fit different roof profiles


  • More costly than other methods of metal roof restoration
  • Becomes membrane roofing with different maintenance requirements

2. Hat Channel Method

This method uses hat channels and metal bars with lips on the underside to hold insulation. It’s also a great way to restore a metal roof without removing insulation.

The hat channels are installed over the existing roofing material and fastened in place with fasteners or clips. Drip edges are installed over the eaves and along all rakes to hide the existing roof and give it a smooth finish.


  • You can match your existing roof profile and color, so it will look as if nothing has changed.
  • It can be installed in one day with minimal disruption and is generally less expensive than a complete roof replacement.


  • It has no warranty, so you will have to pay for a complete roof replacement if the material fails.

3. Retro-R Panel

Retro-R Panel is a quick and efficient method for metal roof restoration. This restoration involves covering the existing roof with retrofit panels that are screwed on top of the existing metal roof. These panels feature a built-in factory-applied sealant for superior protection against water intrusion while providing increased insulation.


  • Cost-effective method to restore a metal roof
  • Provides undercoating to prevent rust from transferring to new panels


  • Only fits R-panel roofs
  • Not aesthetically pleasing compared to other roof restoration methods

4. Silicon Coatings

Silicon coatings are a popular and effective way of restoring metal roofs. This technique involves applying a liquid silicone material to the roof’s surface, which provides a protective layer against corrosion and UV radiation.

Silicon coatings are also highly resistant to water intrusion, which can help extend the life of a metal roof. However, this method is more preventative than restorative, so it may not be suitable for severely damaged roofs.


  • Easy application
  • Available in various options for different types of roofs


  • Not suitable for sealing heavily oxidized metal
  • Doesn’t stop leaks
