FAQ: Can I Install Solar on a Metal Roof?

At BC Solar, we get this question a lot — especially from business owners with standing seam or ribbed metal roofs on warehouses, retail buildings, and agricultural sites across Columbus and Central Ohio.

Here’s the good news:

Yes, you can absolutely install solar on a metal roof — and in many cases, it’s one of the best roofing types for solar.

Let’s break it down:

Why Metal Roofs Are Ideal for Solar

Metal roofs and solar panels are a great match. Here’s why:

1. No Roof Penetrations Needed

We use specialized clamp systems that attach directly to standing seams or ribs of your metal roof. That means:

• No drilling

• No roof penetrations

• No leak risk

This method keeps your roof warranty intact and avoids any long-term moisture issues.

2. Long Lifespan Matches Solar

Most metal roofs last 40–70 years. Solar panels typically last 25–30 years.

When your roof outlasts your panels, you don’t have to worry about a costly roof replacement interrupting your solar investment.

3. Lower Labor & Mounting Costs

Installing solar on a metal roof often reduces the amount of racking hardware and labor needed — especially with standing seam metal roofs. That can lead to savings on your overall installation.

4. Flat and Low-Slope Metal Roofs Work Too

We can install on most types of commercial roofs:

• Standing seam metal

• Corrugated and ribbed panels

• Flat metal roofs (using a ballast or tilted mounting system)

What If I Have a Flat Commercial Roof?

Flat roofs are also great for solar — metal or otherwise. We use weighted mounting systems that don’t require roof penetrations and allow panels to be tilted toward optimal sun exposure.

This is common for:

• Schools

• Warehouses

• Grocery stores

• Large municipal buildings

FAQs

How do you attach solar panels to a metal roof without drilling?

We use S-5 clamps or similar mounting systems that fasten to the seams or ribs of your roof. No drilling is needed for standing seam roofs.

Does solar work with corrugated metal roofs?

Yes, but we’ll need to use different mounting brackets that may involve minimal penetration. We’ll always ensure proper sealing and protection.

Will solar panels damage my metal roof?

No. When installed correctly using appropriate hardware, solar panels protect your roof by shielding it from the elements.

Can I add solar to a metal roof that already exists?

Yes. We often install solar systems on existing buildings with metal roofs — whether they’re 5 years or 25 years old.
