Can Solar Panels Be Installed on a Metal Roof? A Practical Guide from Efficient Home Services
For homeowners and businesses alike seeking to reduce energy bills and minimize their carbon footprint, solar has a well-established track record as the answer. But one thing gets asked a lot when people first start investigating solar: Will solar panels work if I have a metal roof? The short answer is yes, but there are critical factors to consider in regard to your type of roof, mounting systems for solar panels, and installation methods.
Custom Solar Solutions That Work With Your Metal Roofing
At Efficient Home Services, we see the whole picture and come up with custom solar solutions that fit all the puzzle pieces together, even metal roofing.
In this post, we examine whether there are any issues with installing solar panels on metal roofs, what concerns you might have about mounting solar panels on metal, and how to make sure you get long-term benefits and savings from solar with Efficient Home Services.
Why Metal Roofs and Solar Panels Are a Perfect Match
Because metal roofing materials last so long, they’re considered a “forever” product that won’t need to be redone in your lifetime. Also, solar provides clean, affordable energy and significant savings on utility bills. These two technologies are perfect for each other when combined.
Believe it or not, metal roofs are very solar-friendly and even superior to other roofing styles. And their lifespan perfectly mirrors the average 25-to-30-year lifespan of solar panels. Asphalt shingles may have to be replaced halfway through the life of a solar system, whereas a metal roof will outlast your panels, saving tens of thousands of dollars on a second installation.
So, can you put solar panels on a metal roof? In a word, yes — but the way you go about it will depend on your roof’s design and its layout.
Types Of Metal Roofs Explained
Metal roofs are not all created equal. It comes with different mounting obstacles and opportunities for each type:
Standing Seam Metal Roofs
These are descriptions of roofs with seams that have been lifted up vertically, from ridge to eave. They are also particularly well suited for solar installation since the seams can double as mounting anchors for solar panels. No drilling is necessary, clamps provide secure and easy fastening of the system without penetrating the surface of the roof(pub.RequestBody:No drilling necessary- clamps enable the system to be secured without penetrating the roof surface. This greatly reduces the chances of leaks and protects your investment (roof).
Corrugated Metal Roofs
Corrugated standing seam panels are wavy, and usually, you have to drill holes to install solar mounting hardware. While a little more invasive than clamps for standing seam, this can still be attached securely with waterproof seals and flashing to avoid leaks.
Metal Shingle Roofs
Metal shingles are designed to look like slate or tile. This kind of roof installation is more complicated and frequently needs custom mounting brackets and flashing. However, Efficient Home Services is an authority on making a clean, lasting placement.
Customized For Metal Roofs
You aren’t employing the same tactics for mounting solar panels on a metal roof across the board. The technique we employ will vary depending on the profile of your roof. Here are some of the most popular tactics:
Seam Clamps: Perfect for standing seam roofs, these clamps clip onto the raised seams without damaging the roof.
L-Foot Brackets with Flashing: For corrugated or ribbed panels, these brackets drill down through the metal roof and secure to the structure below. Watertight seal with flashing and rubber gaskets.
Rail-less Installation: Where possible, we attach the solar panels directly to the roof with fasteners in the right places, minimizing weight and time.
Our solar engineers perform a full roof inspection to determine the best method for mounting on your home or commercial building.
How Do They Get Through the Roof Without Leaking?
Some of the most frequent questions we receive are regarding drilling a hole into a metal roof and what’s involved with the process, and if drilling into a metal roof will ruin the weather-tight integrity of it. Though a fair thing to wonder, the risk is low when a professional installs the system.
If penetration is needed (like with corrugated or shingle metal roofs), we incorporate specialized hardware and flashing kits to ensure complete air-tightness. We use butyl rubber gaskets, stainless steel bolts, and UV-resistant sealants to keep your system leak-free for generations.
Also, the shape of a metal roof will typically shed water, which reduces the likelihood of water hanging around for months.
Energy Efficiency Synergy
Here’s an unsung upside: Metal roofs can make solar panels function more efficiently. Many of them are painted reflective, which reflects heat and thus cools the buildings and cuts the expense of air conditioning. And when the solar panels surrounding the green roof are taken into account, the cooling and shading process only accelerates, making the pairing naturally energy efficient.
And the longevity of metal roofs, which are wind- and hail-resistant and not flammable, of course, lends an additional layer of protection to your solar array. You’ll spend less on maintenance, and you’ll worry less about weather-related damage.
Does It Take Longer to Install on a Metal Roof?
Yes and no—especially for more intricate metal shingle designs calling for custom-made brackets or flashing. However, the time difference is usually only slight, and our installers are specialized in metal-roof installations.
At Efficient Home Services, our focus is on the Planning stage before installation. Our Project Managers organize specific dimensions of the roof, layout the mounts, and file for permits to help the process go smoother. The result? You get your solar panels up and running quicker, with fewer shutdowns or returns.
Are They More Than a Solar Panel Roof?
The up-front cost of installing solar on a metal roof may be slightly more expensive than installing it on traditional asphalt shingles, depending on the mounting method and roof type. But more often than not, this can be a small difference, and the long-term savings compensate for that difference fast.
With a longer-lasting, lower-maintenance roof, your solar investment is secured over the years. You also sidestep the substantial expense of removing and reinstalling panels on a mid-life roof replacement, something that’s commonly overlooked in the original project’s budgeting.
So, Can You Install Solar Panels on a Metal Roof?
To sum it up: Yes, you can put solar panels on a metal roof — and in many instances, you will see better results than those of non-metal alternatives. When planned for and installed correctly, metal roofs can also accommodate an extremely efficient and durable solar system.
