Can i put solar panels on a metal roof

Metal roofs are becoming more and more popular because they last longer than other types of shingles and tiles that many people have used in the past to cover their homes.

But can you put solar panels on a metal roof?

The short answer is yes, but this question is not as straightforward as it may seem.

Solar panels are typically installed on roofs made of asphalt shingles or tile, but can also be installed over a metal roof.

However, in order to install solar panels, the metal needs to have enough space for an attachment point and sufficient insulation below the surface for wiring from the power inverter.

In this article, we will go through all the qualifications your roof must have to know exactly whether you can install solar panels on a metal roof or not.

So without further ado, let’s jump right into it.

Can solar panels be installed on a metal roof

There are many types of metal roofing materials to consider when deciding whether you can install solar panels on a metal roof.

Here’s an overview of some roofs that do and don’t work with solar panels:

– Metal Shingle Roofs – Yes, but only if they are asphalt shingles and not galvanized steel (more below).

– Standing Seam Metal Roofs – Yes, as long as they are not painted.

– Corrugated Metal Panels – Only if the roof is a standing seam roof and you have enough space for insulation below it (more below).

– Flat Exposed Fasteners Metal Panel Roofing Systems – No because there isn’t any room on top of them for wiring and you can’t insulate them.

– Metal Tile Roofs – No because they are not flat enough.

Asphalt Shingle Roofs: As mentioned above, asphalt shingle roofs work fine as long as the metal isn’t galvanized steel. In other words, if your home has a prefabricated standing seam metal roof, it is not compatible with solar panels.

Galvanized Steel Roofs: Galvanized steel roofs are composed of a thin sheet of metal that has zinc coating on the outside to protect against corrosion and rusting. These types of roofs can’t be used for solar panel installation because they don’t have enough space between the metal sheets for insulation and wiring.

Insulation: To hold up a solar panel, there needs to be enough room between the metal roofing surface and whatever is underneath it for a mounting bar or bracket.

In addition, some types of metal roofs require that you insulate them from the heat before installing your panels on top of them. Check with an installer to see if insulation is required for your roof type.

Best Metal Roofs For Solar Panels: If you are looking to install solar panels on a metal roof, standing seam roofs are one of the best choices because they can be installed with or without insulation underneath them and usually have enough space between the sheets for wiring.

They also allow easy access to the roof for maintaining your panels in the future.

That being said, standing seam roofs are more expensive than other types of metal roofs (about $15 per square foot).

If you don’t want to install solar panels on a metal roof but still like the look and feel of these homes, consider using steel shingles instead because they provide the same protection as standing seam roofs but are much cheaper (about $25 per square foot).

It is important to point out that metal roofs can last for decades, so it’s important to consider the initial cost over time when deciding whether you want solar panels on a metal roof or not.

At this moment in time, they are one of the most expensive types of roofs you can install.

In short, the decision whether to put solar panels on a metal roof or not depends on your budget and how long you plan to own it for.

If you don’t mind spending a little extra up front, standing seam roofs are one of the best options because they allow easy access to your system in the future.

Last Words

If you are planning on staying in your home for more than 20 years, then metal roofs can be a great choice because they will probably last that long with no problems (and possibly even longer).

However, if you plan on selling or moving soon, it might not make sense to spend extra money up front when the roof itself is the only thing you will see when the solar panels are removed.

In any case, metal roofs can be a great choice for homeowners who want to install solar panels on their roof but don’t have enough space or desire to put them in an area where they can easily be accessed and serviced in the future (like at ground level).

While this is a great option for homeowners who like the look and feel of metal roofs but also want to go green, it’s important to remember that they can be one of the most expensive types of roofs you can install.
