Are you considering going solar, but having a metal roof?
The good news is that you can install solar panels on metal roof. However, before you jump in and start the installation process, there are several factors to consider.
From the condition of your roof to local regulations and everything in between, this article will guide you through what it takes to successfully install solar panels on a metal roof.

It Depends on the Condition of Your Roof
Before installing solar panels on your metal roof, it’s important to evaluate the condition of your roof. A damaged or worn-out roof can not only compromise the installation process but also put the entire system at risk. The first step is to have a professional roofer inspect your metal roof. Have them identify any areas that need repair or replacement. This will help ensure that your new solar panel system won’t cause further damage to an already weakened structure.
It Depends on the Age of Your Roof
A new or relatively new roof is an ideal candidate for solar panel installation. This is because it can withstand the weight of the panels and reduce the risk of damage. However, if your roof is older, it may not be strong enough to support solar panels for the roof. An old metal roof can also have corrosion and rust issues. This could affect how well it holds up under the added weight of solar panels over time. In this case, if you are looking for solar installers, consult with a professional roofer or solar contractor. They can assess its condition and provide recommendations.
It Depends on the Right Mounting System
The type of mounting system you choose will depend on several factors. This includes:
- your local weather conditions
- the wind speeds
- the size and weight of your solar panels
Rail-based systems use aluminum rails attached to the metal roof with clamps. Rail-less systems attach directly to the standing seams of a metal roof using special brackets. The choice between these two options depends on several factors such as:
- ease of installation
- maintenance needs
- overall durability
For instance, if you live in an area with high winds or heavy snowfall during winter months then a rail-less system may not be ideal for you because it could lead to damage over time due to increased stress placed upon brackets that support each panel.
It Depends on the Proper Grounding
Proper grounding is crucial for any solar panel system. This is regardless of the type of roof it’s installed on. When we talk about grounding, we’re talking about providing a safe path for electrical currents to travel in case of a fault or surge. This is more important because metal roofs are good conductors of electricity. Without proper grounding, there could be an increased risk of electric shock or fire hazards. Proper grounding cannot be overlooked as it plays an essential role in keeping both people and property safe.
It Depends on the Pitch of Your Roof
The angle at which the roof slopes affect how much sunlight the panels receive and, consequently, their efficiency. A metal roof with a steep pitch of more than 30 degrees is ideal for solar panel installation.
This is because it allows for maximum sun exposure throughout the day. Conversely, roofs with a shallow slope or flat roofs may not be suitable since they receive less direct sunlight and could compromise energy production.
It Depends on the Direction of Your Roof
The direction or the orientation and tilt angle of the panels determine how much sunlight they receive, which directly affects their energy output. In general, south-facing roofs are the ideal location for solar panel installation.
This is because they receive the most sunlight throughout the day. However, if your roof faces east or west, you can still install solar panels and achieve significant energy savings. If you have an east-facing roof, you will get more sun exposure in the morning than in the afternoon. This may be beneficial if you use more electricity during daylight hours. On the other hand, a west-facing roof receives more sun in the evening when the electricity demand is usually higher.
It Depends on the Local Regulations
It’s important to be aware of the local regulations in your area. This is because different jurisdictions have different requirements and restrictions for solar panel installations. Some areas may require permits before you can install solar panels on your roof. You may also need to comply with specific building codes or zoning laws that dictate where and how solar panels can be installed. In some cases, homeowners’ associations or neighborhood covenants may also have rules regarding the installation of solar panels. These rules could limit the size or placement of your solar panel system, or even prohibit them altogether.
It Depends on the Maintain the System
Due to their lighter weight compared to traditional rooftop materials like asphalt and tile, metal roofs can further decrease their longevity if not properly maintained and supported. For the long-term success of any solar panel system, there needs to be regular preventative maintenance, including cleaning the panels and monitoring connections. This is in addition to regular inspections to ensure the integrity of the metal roof and the panels.
Know What You Need When Having Solar Panels on Metal Roof
Having solar panels on metal roof is an increasingly popular way to harness the sun’s energy. Knowing what protective gear, assembly methods, and materials to use is essential for a successful installation.
It is important to take safety precautions and use the right materials and equipment to ensure a long-lasting, durable installation of solar panels on a metal roof. Talk to a solar panel expert today to determine the best solar panel setup for your home.
