Solar Panels on Asbestos Roof: Advantages and Disadvantages

Hey there! So, you’re thinking about installing solar panels on your asbestos roof, huh? Well, you’ve come to the right place. We’re here to break down the advantages and disadvantages of this setup so you can make an informed decision. Now, before we dive in, let’s quickly cover the basics. Asbestos roofs were once popular due to their durability and fire resistance, but concerns about health risks have led many to consider alternatives. But, will pairing solar panels and asbestos roofs be a good idea? Let’s find out.

What do you think? Can Solar Panels be Installed on Asbestos?

You can install solar panels on asbestos roof, but there are some key considerations to keep in mind. When it comes to drilling on asbestos roofs, we have to proceed carefully. Asbestos, as you may know, poses health risks when broken, so any drilling or installation work needs to be done by professionals who understand the proper safety precautions.

Now, let’s talk longevity. Asbestos roofs are known for their durability, often lasting decades without needing much maintenance. However, when we introduce solar panels into the mix, we need to think about how they might affect the lifespan of the roof. The good news is that when installed correctly, solar panels can actually provide some protection to the underlying roof, shielding it from the elements and extending its lifespan.

But what about the weight? Solar panels aren’t exactly feather-light, so we need to make sure that your asbestos roof can handle the extra load. Again, this is where professional assessment comes in handy. They can evaluate the structural integrity of your roof and determine if any reinforcements are needed to support the weight of the solar panels. 

If your asbestos roof is not sturdy in the structure below can mount the solar panels. Mounting angles can be used to make a sturdy structure above the asbestos roof. Additionally, you can choose special mounting structures that distribute the load of the solar panels. Overall, while there are some challenges to installing solar panels on asbestos roof, it’s definitely doable with the right expertise. 

Why Installing Solar Panels Can Be a Bad Idea for You?

Alright, let’s get into why installing solar panels asbestos roof might not always be the best idea. First off, it’s important to understand that asbestos roofs come with their own set of challenges. Here are the top reasons why it might not be feasible:

Asbestos has Many Health Risks 

As we know, one of the Asbestos disadvantages is it can pose serious health risks if disturbed. Installing solar panels typically involves drilling or otherwise manipulating the roof, which can release asbestos fibers into the air. This is a major safety concern that needs to be addressed by professionals with the right training and equipment.

It does not Have a Proper Structural Integrity

Asbestos roofs, might not be able to support the weight of solar panels. If you add the additional load of solar panels and mounting equipment it could compromise the structural integrity of the roof. This can lead to safety hazards and costly repairs down the line.

Keeping your Roof Well-Maintained

To get the full utility out of your roof you have to keep it properly maintained. Installing solar panels can make it more challenging to access and inspect the roof, potentially leading to issues going unnoticed until they become serious problems.

You will have Limited Options for Attachment 

Another asbestos sheet disadvantage is attaching solar panels securely to an asbestos roof. This process can be tricky. Traditional mounting methods may not be suitable for asbestos, requiring specialized devices that can be more complex and costly.

Overall, while the idea of harnessing solar energy is appealing, there are significant solar panels asbestos roof disadvantages. It’s crucial to weigh the potential risks and challenges against the benefits before moving forward with any plans.

Are you Weighing the Idea of Changing to Metal Roofs?

If your asbestos roof is nearing the end of its lifespan or showing signs of deterioration, it might make sense to replace it before installing solar panels. This ensures that you have a solid foundation for your solar array and reduces the risk of future complications.

Considering replacing your asbestos roof with a metal one to make way for solar panels? Let’s weigh the pros and cons to see if it’s worth the investment.

Let us talk about the Pros of Swapping to Metal Roofs

  • Metal roofs are known for their longevity, often lasting 50 years or more with proper maintenance. This means you’ll have a solid foundation for your solar panels that will stand the test of time.
  • Metal roofs are typically lightweight compared to other roofing materials, which can make them easier to work with when installing solar panels. You won’t have to worry as much about structural reinforcements to support the added weight.
  • Metal roofs are naturally reflective, which can help keep your home cooler and reduce your energy bills. When paired with solar panels, you could see even greater energy savings over time.
  • A new metal roof can boost the curb appeal and resale value of your home, making it a worthwhile investment even beyond the benefits of solar energy.

What are the Cons of Replacing Asbestos with Metal Roofs?

  • There’s no denying that replacing your roof is a significant investment. While metal roofs can be more expensive upfront than some other options, the long-term benefits may outweigh the initial expense, especially when combined with solar panels.
  • Installing a metal roof can be more complex than simply laying down asphalt shingles. It requires skilled labor and specialized equipment, which can add to the overall cost and timeline of the project.
  • Not all metal roofs are created equally for solar panel installation. Some types of metal roofing may be better suited for solar than others. So, you should choose the right material and work with experienced professionals who understand the requirements.
  • While metal roofs can be stylish and modern, they may not be to everyone’s taste. It’s important to consider how a metal roof will complement the overall look of your home.

In the end, whether replacing your asbestos roof with a metal one is worth it for installing solar panels depends on your unique circumstances and priorities. We recommend consulting with roofing and solar experts to explore your options and make an informed decision that suits your needs and budget.


As we saw in the above sections, installing solar panels on an asbestos roof has its pros and cons. Solar panels offer clean energy and potential cost savings. However, there are many challenges that you can face while installing solar panels on cement sheet roof. If you think that you have a strong structure that supports your Asbestos roof you can opt for solar panels. But, even if you have the slightest of doubts, change your roof to a metal structure.
