The top 7 Factors of Making a Roof Suitable for Solar Panels

Prepare Your Roof

The increasing demand for clean energy has made solar power a popular choice for homeowners and businesses. Solar panels are a great way to reduce your carbon footprint and save money on energy bills. However, not all roofs are suitable for solar panels. To help prepare the future of your home we have built a guide to discuss the top 7 factors that make a roof suitable for solar panels.

Roof Orientation and Tilt

The orientation and tilt of your roof play a crucial role in determining whether it is suitable for solar panels. Ideally, your roof should face south or southwest to get maximum sunlight exposure throughout the day. Additionally, the roof should have a tilt of 15 to 40 degrees to ensure optimal energy production. If your roof does not face the right direction or has a low pitch, it may not be suitable for solar panel installation.

Roof Age and Condition

Before installing solar panels, it is essential to assess the age and condition of your roof. Solar panels are designed to last for at least 25 years, which is the average lifespan of most roofs. If your roof is older than 15 years or shows signs of damage, it may need to be repaired or replaced before solar panel installation. A strong and sturdy roof is necessary to support the weight of the solar panels and ensure their longevity.

Roof Material

The material of your roof can affect the installation and performance of solar panels. Asphalt shingle roofs are the most common type of roof and are suitable for solar panel installation. Other suitable roof materials include metal, tile, and slate. However, if you have a thatched or cedar shake roof, it may not be suitable for solar panels due to their uneven surface and potential for damage.


Shade is one of the most significant factors that can affect solar panel performance. Trees, buildings, or other obstructions that cast shadows on your roof can significantly reduce the amount of sunlight that your solar panels receive. To ensure optimal energy production, your roof should be clear of any shading, especially during peak sunlight hours. If your roof has shading issues, you may need to consider other locations for solar panel installation or remove the obstructions.

Roof Size and Shape

The size and shape of your roof can also affect solar panel installation. A large, flat roof with few obstructions is ideal for solar panel installation. If you have a small or irregularly shaped roof, it may be challenging to install enough solar panels to meet your energy needs. In such cases, you may need to consider alternative energy sources or consult with evergreen solar energy to design a custom solar panel system.

Our Services

Electrical Capacity

Before installing solar panels, it is crucial to ensure that your electrical system can handle the additional load. Solar panels generate direct current (DC) electricity, which needs to be converted into alternating current (AC) electricity to power your home. Our team of professional fitters can assess your electrical capacity and determine if any upgrades are needed to support solar panel installation.

Local Building Codes

Lastly, it is essential to comply with local building codes and regulations when installing solar panels. Building codes can vary depending on the area. Failure to comply can result in fines or legal issues. It is important to work with our company who is knowledgeable about local building codes and can ensure that your installation is up to code.
