When installed by a qualified solar installer, solar panels should not cause any damage to your roof. In fact, solar panels can protect your roof from the elements! However, there are instances where things can go wrong, especially if your roof’s structure is compromised and can’t handle the extra weight or if you attempt a DIY installation.

We, the solar panel experts at Eco Happy, will tell you more about how solar panels are mounted and some of the precautions you can take to avoid any damage to your roof. Don’t let the fear of roof damage deter you from all the benefits that come with investing in solar energy!

Does Solar Panel Installation Create Holes in Your Roof?

One of the things that property owners are most concerned about when it comes to solar panel installations is the holes created by the mounting hardware. However, these holes are typically very small and shouldn’t cause roof leaks or other potential issues.

Learning more about how solar panels are mounted should give you better insight into why these small holes are necessary.

How solar panels are mounted

Solar panels are typically mounted and secured on top of your roof’s rafters. Long bolts are used to attach the mounting hardware to your roof so that the solar panels are properly secured. A sealant is placed around the bolts to prevent leaking.

Tilting mounts follow the movement of the sun and require more complex installation. The installation process may also differ depending on your roofing material.

Does Removing Solar Panels Cause Damage to Your Roof?

Removing solar panels should not cause any damage to your roof, but an experienced team should always carry out the process. If you ever decide to remove your solar panels, you can simply cover the small holes left by the mounting with a moisture-resistant sealant.

Does solar panel replacement cause damage to your roof?

Solar panels typically have a lifespan of around 20 years. When it comes time to replace your system, you can usually keep the same mounting and just replace the panels.

What Precautions Should You Take To Avoid Damage To Your Roof?

While there is very little risk of roof damage when it comes to solar panel installation, there are still a few precautions you can take to protect your roof.

Don’t opt for DIY

While attempting to install your own solar panels may seem like a good way to save money, you run the risk of improper installation. You could end up damaging the panels, damaging your roof, and even injuring yourself.

Choose experienced solar installers

Choosing inexperienced solar installers could result in shoddy workmanship. Rather, choose installers who have been around for a while and have built up a trustworthy reputation within your local community, like Eco Happy. This will greatly reduce the risk of any potential damage.

Consider investing in a new roof before you install solar panels

If you have an older roof, it may not cope with the additional weight of the solar panels. It may be a good idea to get your roof structure evaluated by a structural engineer before you invest in solar panels. Proper planning can go a long way in preventing damage.

In some cases, you may be advised to install a new roof or have your roof repaired before installing solar panels.

Clean debris regularly

Many homeowners fail to clean their roofs and panels regularly. When you have solar panels, the risk for debris build-up increases as the space between the panels where leaves and sticks can get stuck. Cleaning will also prevent animals from nesting between your panels and your roof.

Can Solar Panels Protect Your Roof?

Did you know that direct sunlight can deteriorate your roof over time? Other environmental factors, such as wind, rain, and snow, can also cause damage to your roofing materials. Solar panels can actually protect your roof from the elements, thus expanding the lifespan of your roof.

Are There Any Drawbacks to Installing Solar Panels?

If the installation of solar panels is a relatively risk-free process, are there any drawbacks associated with the installation process? The main drawback would have to be the upfront cost. Solar installations typically cost between £5,000 and £13,000, which is a significant amount for the average property owner.

However, once you have made the initial investment, you won’t have to do too much in terms of maintenance. You’ll also enjoy reduced electricity bills and have the option to sell any excess energy to the national grid through the SEG scheme. Overall, solar panels are worth the cost.


How can I make sure my solar panels are installed correctly?

Make sure that you choose trusted and experienced solar panel installers if you want a proper installation. Don’t attempt to handle any of the process on your own and speak to a structural engineer if you have any concerns about your roof’s age and integrity.

Is my roof the only location for solar panel installation?

While most people install solar panels on their roofs, you can also opt for a ground installation. Ground installations may not be the right choice for every property, but they do come with their own unique benefits such as increased solar output. Another option is to install the panels on top of your carport or shed.

Can you install solar panels on a flat roof?

Yes, you can install a solar array on a flat roof but these installations typically require more mounting materials, which can push up the cost. Flat roofs also don’t have as much surface area as sloped roofs, so you may have to opt for a smaller solar panel system.


Provided you take the necessary precautions, solar installation shouldn’t cause any damage to your roof. Just make sure you invest in a professional installation so you can reduce your energy costs without any complications.
