Is Metal Roofing Better or Worse for Solar Panels?

These days, many of us are focused on energy efficiency. That means that you may, at times, need to make upgrades to your property to improve that energy efficiency. For some, that is roofing. For others, it is solar. But what if it might be both?

Now, when we consider roofing, we also have to consider whether or not that roofing can handle the needs of solar panels. Metal roofing, which offers incredible energy efficiency, is still relatively new. So how well does metal roofing handle solar panels? Does the metal make it harder or easier to install?

What Makes Metal Roofing a Great Choice for Solar

Metal roofing is not only useful for solar, but it can be highly advantageous – especially, but not exclusively, if you have not yet installed solar. Some of these benefits include:

  • Durability and Longevity – Metal roofing is characterized by its long lifespan, typically ranging from 40 to 70 years. This longevity is advantageous when paired with the 25-30 year lifespan of solar panels, ensuring that the roof’s integrity remains uncompromised for the duration of the solar panels’ use.
  • Structural Considerations – The lightweight nature of metal roofs is a significant advantage. They can support the weight of solar panels without necessitating additional structural reinforcement, which is often required for heavier roofing materials.
  • Installation Process – Metal roofs, particularly those with standing seam designs, offer a straightforward installation process for solar panels. The ability to attach panels directly to the seams without drilling reduces the likelihood of leaks and structural damage.
  • Thermal Performance and Energy Efficiency – Metal roofs reflect solar radiation, which can contribute to lower cooling costs. This reflective property, in conjunction with solar panels, can enhance overall energy efficiency.

For those that are choosing solar for the environment, you may also be comforted to learn that the eco-friendliness of metal roofs, often composed of recycled materials and being fully recyclable, aligns well with the sustainable nature of solar power.

Considerations and Challenges

These advantages of metal roofing for solar does come with a caveat, and that is that certain types of solar panels may require specialized mounting systems or may not perform optimally on metal surfaces. It is essential to consult with solar installation professionals to ensure full compatibility.

However, in general, metal roofing, with its durability, ease of installation, energy efficiency, and environmental benefits,  presents a more favorable option for solar panel installation compared to other roofing materials. While initial costs and specific compatibility issues should be considered, the long-term advantages make metal roofing a very smart choice for most solar panels.
