Metal Roofs Are Durable Enough To Outlast Your Solar Panels

How to Install a Solatube on a Metal Roof with a specially flashing

Solar panels are extremely durable and can last for 25 to 30 years, which is part of what makes them such a great investment for your home. However, in many cases, this means that your solar panels can outlive your roof, which can result in an added expense. If your roof is aging, you have to replace it before installing solar panels, or incur the additional cost of removing and re-installing your panels when the time comes to replace your roof.

Metal roofs, on the other hand, are the most durable conventional roofing material available. If you have a metal roof on your home, it will likely last longer than the lifespan of your solar panels, which reduces expense and hassle in the long term.

Do I Need A New Roof Before I Put Solar Panels On

Whether you need a new roof for your solar panels depends on a few factors, but the main factor to consider is the condition of your current roof. Your roof should be fairly new and in good condition if youre going to install solar panels on it.

According to the National Association of Home Builders , asphalt shingle roofs by far the most popular roofing material last about 20 years. Of course, condition does not always directly correlate with age, so its important you know not only how old your roof is but also what sort of shape its in currently. Especially if your roof is more than five years old, you should consider having a professional evaluation done on your roof to help determine whether it is holding up well and is ready for solar panels.

If your roof is nearing the end of its projected lifespan or is in poor condition, then you are typically better off replacing it before installing solar panels. This ensures your roof will be able to support the solar panels, which weigh about the same as adding a second layer of shingles, and keeps you from having to pay to take down the panels when it comes time to replace the roof and reinstall them after the new roof goes on.

Can You Put Solar Panels On A Copper Roof

We’re getting more and more inquiries about the feasibility of solar panels on a copper roof. The answer is yes, it can be done. But our recommendation for those who considering copper diamonds, tiles, or shingles is to combine profiles so that the solar panels are mounted to panels. Here’s why.

Tile and shake profiles simply aren’t intended for repetitive foot traffic. While they can be walked on without significant damage – and indeed, the installer has to walk on them during installation – too much foot traffic could result in denting.

The traffic that comes with the installation and maintenance of a solar roof system could compromise the aesthetic of any metal roof, though its performance would likely not be affected.

Types Of Roofs With Solar Panels

Solar Panels on Metal Roof

There are several different roofing materials, and each poses its own set of advantages and drawbacks. Still, nearly every type of roof can accept solar panels.

Some of the most common types of roofs with solar panels include:

  • Asphalt Shingle
  • Stone
  • Ceramic Tile

These roof types tend to be durable enough to withstand the additional weight and pressure of a mounted solar panel.

Most residential solar panels dont lie entirely flat against the surface of a roof. Instead, theyre mounted onto thick metal stands that allow them to sit at different angles. This helps them absorb as much sunlight as possible.

Sometimes, the mounts do hold the panels at a particular angle. Homes located in sunny environments may not need shifting panels, so a simpler stationary installation is often preferable.

That said, there are also peel-and-stick solar panels that could also be an excellent option for homeowners with non-traditional roofing. But for those with metal roofs, a standard mounted installation is likely the best route.

How Much Does It Cost To Install Solar Panels On A Roof

This actually varies greatly depending on the wattage of your system. Most homes in the United States will have systems that are between 3kW to 8kW in rating, with 6Kw being the most common. A typical system will cost between $2.50 to $3.50 to install, though some may charge extra due to the presence of metal roofing.

A typical solar panel is pretty large, often upwards of 400 square feet. This means that a typical installation can range between $9,000 to $28,000 depending on the wattage as well as the overall size of the panels. While the range itself is high, you can expect a price tag of around $19,000 for panels on a metal roof.

If the price of solar panels is intimidating, dont panic. They pay for themselves in both tax rebates as well as decreased electricity bills. In fact, many companies will even help you finance them. When in doubt, just ask what is available to you.

Metal Roofs Are No Problem For Solar Panels

As you can see, if you have a metal roof on your home or business, going solar is no problem. There are many products on the market that will allow you to mount solar panels.

In fact, metal roofs are the best type of roof to pair with solar panels. Because metal roofs have such long lifespans, thereâs much less of a chance of developing a roof leak that will require you to pay the extra cost of removing and reinstalling the solar panels.

And if you have a standing seam metal roof, thatâs the best situation of all because you can use a clamp system that doesnât put holes into your nice roof. This also reduces the installation labor and your system costs.

No Penetration (Part 1) Metal Roof Solar Panel Install !

The most common roofing material in the United States is asphalt shingles, and for good reason: theyâre inexpensive, durable, and come in a wide variety of styles and colors. But while theyâre less popular, metal roofs have a lot of advantages. If youâre a homeowner with a metal roof, you might wonder: can you install solar panels on them?

The answer is: yes! While the majority of solar homes have asphalt shingle roofs, metal roofs are actually a better choice if youâre planning to go solar. This is because one of the main concerns with a rooftop solar installation is ensuring theres enough life left in the roof before putting panels on top of them. If a roof fails early, itâs an extra expense to remove the solar panels before the roof repair can proceed. But metal roofs last a really long time, making the age of the roof less of an issue.

How the solar panels are mounted will depend on the exact type of metal roof you have.
