Roof Considerations When Installing Solar Panels

roof installing solar panels

There are a few key home or building components that may play a major role if you’re looking to install solar panels in your property, and perhaps the single most notable here is the roof. The roof is the most popular location for solar panel installation by far, and there are a few basics you need to be considering with regard to whether your roof is ready for a solar panel installation and the future needs it carries.

At The Roof Doctor, we’re happy to offer a huge range of roof repairs and roof installations to clients around Salt Lake City, West Valley City and West Jordan. Here are some basics on why roofs are so useful as solar panel mounting locations, plus which roof materials are ideal for solar panel setups and how to determine whether your roof is ready for such an installation.

Why is the Roof the Primary Solar Panel Location?

Before we dig into the specifics of roof materials and readiness for solar panel installation, it’s important to understand why roofs are the primary location for such installations. There are a few key reasons:

  • Accessibility – Solar panels need direct sunlight in order to generate energy, so they should be located in an area where they can get unfettered access to the sun. Roofs are ideal for this because they’re usually one of the highest points on a property and typically provide an unobstructed view of the sky.
  • Durability – The roof is also designed to be durable, so it can hold up against varying weather conditions and any strong winds that might affect solar panel installations.
  • Less likely to be in shade – Unlike other locations around a property, the roof won’t be left in shade by trees or buildings. This maximizes the amount of time during which solar panels can get direct sunlight, and therefore generate more energy.

Roof Type and Solar Panels

One of the first key considerations here is which type of roof you’re working with. There are many roof styles out there, including gable, hip, flat, gambrel, and more. Generally speaking, most roof types can be used for solar panel installations, but some may require additional bracing or reinforcement in order to ensure that the panels are secure and stable.

Even some specialty roof types or features can accommodate a solar panel installation pretty easily. A roof with skylights, for instance, may need to have the frames reinforced before panels can be mounted, but this is still possible. The same goes for roofs with a steep pitch or those with an irregular shape.

Roof Materials (Shingles) and Solar Panels

Another very important consideration is the type of roof material you’re working with. Generally, solar panels can be installed on most residential roofs as long as they are made of asphalt shingles or metal. Asphalt shingle roofs are ideal for solar panel installations because they provide a secure base, plus they can easily handle the extra weight added by the panels.

It’s also important to check on the actual quality of the shingles before installing panels, as they should be in good condition and free of any damage or wear. If you need to replace your shingles before mounting the solar panels, that’s a project best handled by professional roofing specialists like those at The Roof Doctor.

Slope Considerations

As you’re determining whether or not your roof is suitable for a solar panel installation, you’ll also need to consider the slope of the roof. Generally speaking, it’s best to install panels on a relatively flat surface with a pitch of no more than 20 degrees. If your roof has a higher pitch than that, it may still work, but additional reinforcement and bracing may be needed.

Orientation of the Roof

As you may have already assumed, the orientation of your roof can have a major impact on the success of your solar panel installation. This is because it will determine how much direct sunlight the panels are exposed to for an extended period of time, which in turn affects their efficiency and power output.

Ideally, you should install solar panels on a south-facing roof or one that faces east or west. This ensures optimal exposure to direct sunlight throughout the day. If your roof doesn’t face in any of these directions, you can still install solar panels and enjoy some level of efficiency, but it won’t be as high as if your roof was facing south.

Overall, when considering whether your roof is ready for a solar panel installation, it’s important to consider the type of roof you have, the materials it’s made from, the slope, and its orientation. All these factors combine to determine whether your roof is suitable for solar panels and if additional bracing or reinforcement is needed.
