A metal roof is one of the best surfaces you can put solar panels on. If you already have one, or you’re thinking about getting one, you’re in a good position to go solar. Here’s why, and what to know before you install.
Why Metal Is a Match for Solar
The first thing that makes metal roof great for solar is it will generally last about as long as the panels. Solar panels typically last 25 to 30 years or more. A good metal roof can last 40 to 70 years. With asphalt shingles, many homeowners end up removing and reinstalling their panels partway through the system’s life so the roof can be replaced, which is an expensive extra step. With metal, you’ll likely never have to.
A metal roof can also make installation simpler and cleaner. Depending on the type of metal roof, panels can often be mounted without drilling a single hole. Fewer holes means fewer chances for leaks.
Finally, metal stays cooler. Metal roofs reflect a lot of heat, and solar panels work more efficiently when they stay cool. It isn’t a dramatic boost, but it helps.

Metal Roof Matters
Not all metal roofs are installed the same way:
- Standing seam. This is the ideal case. Raised seams run vertically between panels, and installers attach clamps directly to those seams. No drilling and no holes in the roof. It’s one of the fastest and lowest-risk solar installs there is.
- Corrugated or exposed-fastener metal. These roofs need mounts that go through the roof. That’s done routinely and safely with brackets built for metal roofing, which come with sealing gaskets that keep water out. Your installer should use hardware made for your specific roof profile.
- Stone-coated steel. This metal is made to look like shingles or tile, and installing on it takes more care. It’s still very doable with an experienced installer.
What to Check Before You Install
- Your roof warranty. Some metal roofing manufacturers have specific requirements for attachments. A quick review now prevents problems later.
- Roof condition. Metal is durable, but loose fasteners, rust, or damaged seams should be fixed first.
- Installer experience. Ask whether they’ve installed on your type of metal roof and which mounting hardware they plan to use.
- Snow and slippage. Snow slides off both metal and glass easily, so you may want snow guards below the array to protect gutters, walkways, and anyone standing below.
Not Just Possible, Preferred
Putting solar on a metal roof isn’t just possible — it’s often the best-case scenario. You’ll likely get a faster install, fewer roof penetrations, and a roof that outlasts your panels, so you won’t have to remove and reinstall the system.
