Is Fibered Aluminum Roof Coating Waterproof? Find Out Here!

Fibered aluminum roof coating is a popular choice among homeowners and building owners due to its effectiveness in protecting roofs against harsh weather conditions.

Fibered Aluminum roof coating

One of the most common questions about this type of coating is whether it is waterproof.

The answer to this question is yes, fibered aluminum roof coating is waterproof.

Fibered aluminum roof coating is made up of a combination of aluminum flakes and fibers that create a reflective and waterproof barrier on the roof.

The aluminum flakes reflect sunlight, which helps to keep the roof cool and prevent damage from UV rays.

The fibers in the coating help to create a strong, durable barrier that is resistant to water, wind, and other elements.

In addition to being waterproof, fibered aluminum roof coating also provides other benefits, such as increased energy efficiency and improved durability.

However, it is important to note that there are limitations to this type of coating, and proper maintenance is required to ensure that it remains effective over time.

Understanding Fibered Aluminum Roof Coating

Fibered aluminum roof coating is a type of roof coating that is commonly used to protect and prolong the life of a roof.

It is made up of a mixture of asphalt, aluminum, and fibers, which are added to increase the strength of the coating and make it more resistant to tears and breaks.

One of the most significant benefits of fibered aluminum roof coating is its ability to provide waterproofing protection to the roof.

The aluminum flakes create a reflective surface that repels water, while the fiber reinforcement provides strength and durability to the coating, preventing cracks that can lead to leaks.

The asphalt binder is also water-resistant.

When applied correctly, the coating forms a tough, reflective, and weather-resistant surface that can help prevent water from penetrating the roof and causing damage.

In addition to its waterproofing capabilities, fibered aluminum roof coating can also help to reflect sunlight and reduce the heat absorbed by the roof.

This can help to keep the interior of the building cooler and reduce the amount of energy required to cool the space.

It is important to note that while fibered aluminum roof coating is highly effective at protecting the roof from water damage, it is not a permanent solution.

Over time, the coating may begin to wear down and lose its effectiveness, which can lead to leaks and other issues.

Regular maintenance and inspections are essential to ensure that the coating performs as intended and identify any potential issues before they become more significant problems.

Chemical Composition

Fibered Aluminum Roof Coating is composed of aluminum flakes and fibers mixed with solvents and resins.

The aluminum flakes give the coating its reflective properties, while the fibers provide added strength and durability. The solvents and resins help the coating adhere to the roof surface and provide a waterproof barrier.

Application Process

The application process for Fibered Aluminum Roof Coating is relatively simple.

First, the roof surface must be cleaned and free of debris or loose material.

Then, the coating can be applied using a brush, roller, or sprayer. It is essential to apply the coating evenly and to follow the manufacturer's instructions for the recommended number of coats.

Once the coating is applied, it forms a protective layer resistant to water, UV rays, and other environmental factors.

The coating is also flexible, which allows it to expand and contract with the roof's movement, preventing cracks and leaks.

Tips for Proper Application

  • Only apply in dry weather with no precipitation expected for 48-72 hrs
  • Ensure roof surface is clean, dry and prepared properly
  • Apply 2-3 coats for best coverage and waterproofing capability
  • Allow each coat to dry fully before adding the next coat
  • Use a brush, roller or airless sprayer to apply coating evenly

Reapplication schedule:

In warm, humid climates, fibered aluminum coating may need reapplication every 2-3 years. In areas with harsh winters, recoat every 4-5 years. Monitor wear and reapply as needed.

Limitations of Fibered Aluminum Roof Coating

While fibered aluminum roof coatings are a popular choice for waterproofing roofs, they have some limitations that should be considered before application.

Here are some of the key limitations to keep in mind:

Not Suitable for All Roof Types

Fibered aluminum roof coatings are not suitable for all roof types.

They are typically used on flat or low-sloped roofs and may not be effective on roofs with a steep pitch.

Fibered aluminum roof coatings may also not adhere well to certain roofing materials, such as asphalt shingles.

Limited Lifespan

Fibered aluminum roof coatings have a limited lifespan and may need to be reapplied every few years.

The lifespan of the coating can depend on a variety of factors, including the climate and weather conditions in the area, the quality of the coating, and the application method.

May Crack or Peel Over Time

Over time, fibered aluminum roof coatings may crack or peel, particularly if they are exposed to harsh weather conditions or if they are not properly applied.

This can result in water leaks and other damage to the roof.

Not a Permanent Solution

While fibered aluminum roof coatings can effectively waterproof a roof, they are not a permanent solution.

Eventually, the coating will need to be reapplied or replaced.

May Not Be Effective in Extreme Weather Conditions

Fibered aluminum roof coatings may not be effective in extreme weather conditions, such as heavy rain or snow.

In some cases, the coating may even become damaged or dislodged during severe weather events.

Maintenance of Waterproof Fibered Aluminum Roofs

Like any other roofing material, these roofs require proper maintenance to ensure they remain waterproof and in good condition for years.

Here are some tips for maintaining waterproof fibered aluminum roofs:

Regular Inspection

It is important to inspect the roof regularly to identify any signs of damage or wear and tear.

This can include checking for cracks, leaks, or other types of damage.

Regular inspections can help identify potential issues before they become major problems.


Cleaning the roof is also important to maintain its waterproofing properties.

Dirt, debris, and other types of buildup can prevent water from draining properly, which can lead to leaks and other issues.

Regular cleaning can help prevent this from happening.

Signs of wear

Check for cracks, blisters, peeling and areas of erosion/pitting which indicate the coating is breaking down and losing effectiveness.

Repairing Damage

If any damage is identified during an inspection, it is important to repair it immediately.

This can include patching holes or cracks or replacing damaged roof sections.

Repairing damage promptly can help prevent it from worsening and causing more serious issues.

Applying Coating

Another way to maintain the waterproofing properties of fibered aluminum roofs is to apply a new coating periodically.

This can help ensure that the roof remains waterproof and protected from the elements.

The frequency of coating application will depend on various factors, such as the climate and the age of the roof.

With proper application and maintenance, fibered aluminum roof coating can help extend your roof's lifespan and keep your home cool and energy-efficient.

Compare To Other Coatings

Acrylic and asphalt emulsion coatings are less reflective or durable for waterproofing than fibered aluminum.

Elastomeric coatings offer comparable waterproofing but are more expensive.

Seal the Deal: Ensuring Roof Longevity with Expert Advice

In summary, fibered aluminum roof coating is a valuable solution for homeowners and building proprietors, offering a blend of waterproofing, UV protection, and energy efficiency.

Its reflective properties and durable composition provide a robust shield against the elements, prolonging the roof's lifespan.

Ideal for waterproofing?

With proper application on suitable roof types, fibered aluminum coating can be an ideal and cost-effective choice for waterproofing roofs and preventing leaks.

Yet, like all solutions, it has its own considerations and limitations. While it might be tempting to venture into a DIY application, the longevity and effectiveness of the coating largely hinge on a precise application.

Consulting or hiring roofing professionals is highly recommended to achieve the best results and ensure your investment goes a long way.

Their expertise can help navigate the nuances of application and maintenance, assuring your roof remains in prime condition for years to come.
