Got a metal roof? Thinking about installing solar panels?
You’re not alone. As energy prices continue to rise, more and more people are turning to solar panels for their energy needs. Solar panel installation kits are some of the most popular new items sold on Amazon.
But are solar panels on a metal roof compatible? What are the advantages and disadvantages of going ahead with a metal roof solar panel system? Here’s what you should know.
Pros of Installing Solar Panels on a Metal Roof
Installing solar panels on a metal roof offers several advantages. Below are the factors combined to result in an energy-efficient roof that provides reliable and cost-effective energy for years to come:
Reflective
Metal roofs, when combined with solar panels, create a highly efficient system resulting in increased absorption of the sun’s energy. Since metal roofs reflect about 40-60% of solar radiation, far more of the available solar energy is absorbed by the panels.
This results in increased overall efficiency. This reflective quality helps to reduce the temperature inside the home, which reduces the amount of energy needed for cooling.
Strong and Durable
Regularly maintained metal roofs can last 50 years or more, and this durability, combined with the weatherproofing properties, provides an attractive and reliable platform for solar panel systems.
Typically much lighter than other conventional roof materials, metal roofs offer increased stability for the solar panels, along with longer service life. This kind of added structural security and support is ideal for hostile climates or extreme weather conditions.

Low Maintenance
Solar panels require almost no maintenance to keep them running, making them an ideal choice for metal roof owners who don’t want to spend time buzzing around a ladder.
The metal roof on which the panels are installed can also provide an extra layer of protection from weather damage. Solar panels are designed to operate in all sorts of weather conditions, from hot summers to harsh winters.
Despite this, they still require minimal maintenance. This is why they’re so appealing to metal roof owners who don’t want to worry about regular upkeep. With metal roofs, solar panels can be installed in areas that experience extreme weather conditions.
The metal roof itself also serves as an additional layer of protection from harsh elements. With minimal maintenance and an added layer of protection, solar panel installation on metal roofs is an ideal choice for those looking to save on utility costs.
Cons of Installing Solar Panels on a Metal Roof
The cons of installing solar panels on a metal roof include the potential problems associated with heat, reflection, and grounding. Here are to name a few:
The Cost
Installing solar panels on a metal roof can easily double the cost of the project for several reasons. Metal roofs require specific materials and precautions that must be taken to comfortably and safely install the solar panel system.
This adds substantially to the cost. Additionally, due to the difficulty of installation on a metal roof, labor costs can be expensive since they must factor in the potential for damage to the roof and any additional safety measures that must be taken.
Depending on the type of metal roof, it may also become difficult and costly to source any parts that may be necessary for the installation. All in all, while solar panels on a metal roof can provide benefits, potential costs must be taken into consideration.
The Complexity of Installation Requirements
Metal roofs, especially if they are aged or have irregularities, can cause issues with panel installation. Adaptors are needed to attach the panels securely to the metal roof.
The reflective nature of metal can add additional complexity and may potentially affect the performance of the panel. Additional construction may be needed to securely anchor the mountings, frames, and rails of the system.
This is due to the hot climate that typically accompanies most solar panel installations. Metal roof installations can be particularly difficult.
Slippery
The slippery surface of the panels makes it difficult to climb. This can lead to a longer and costlier installation process, as workers may need to take extra safety and time measures while working on metal roofing.
The slippery surface can interfere with the effectiveness of the solar cells, potentially reducing their efficiency and, ultimately, their energy output.
Metal roofing expands and contracts based on its environment, which can lead to further damage to the cells due to the movement. To avoid such risks, installation may need to be performed by a specialized professional, increasing the overall installation cost.
Heat Buildup
This heat buildup can also cause the metal roof to expand and contract too often, leading to potential damages such as leaks and cracks. Additionally, this could reduce the lifespan of the metal roof.
The extra heat will cause the roof to age more quickly than it normally would. Heat buildup can also be a safety hazard, as temperatures may rise too high and become a fire risk.
Therefore, it is important to consider the potential issues that may arise from solar panel installation on a metal roof. In many cases, it is better to install solar panels on a non-metal roof, such as a shingle roof, to reduce the risks of heat buildup.
Explore the Pros and Cons of Solar Panels on a Metal Roof
Overall, the pros and cons of installing solar panels on a metal roof need to be carefully weighed. Though metal roofs come with several advantages, the installation of solar panels comes with a high cost.
Consider all your options to ensure you receive the most affordable and efficient outcome. Request more information from your local solar energy provider for more information.
