Can You Put Solar Panels on a Metal Roof in North Carolina?

Yes, for one main reason: a metal roof can last as long as, or longer than, a solar array. If panels go on an asphalt roof that needs replacing partway through the array's life, you pay to remove and reinstall the array to reroof. Starting with a long-lasting roof avoids that second job.

Metal roofs are also light. Interlock aluminum roofing weighs roughly 0.4 to 0.7 lb per square foot, leaving more of the framing's capacity for the array. A structural check is still part of any solar design.

If your roof is near the end of its life, replace it first. See when to replace a roof in NC.

It depends on the roof type.

Standing seam. The raised seams give solar installers a place to attach clamps that grip the seam, which often avoids drilling through the roof panels. The clamp type must match the seam profile.

Interlocking metal shingles. Slate, Cedar Shingle, Shake and Mediterranean Tile profiles have no exposed seams to clamp, so mounts attach through the roof into the structure with flashing designed for that roofing. The flashing detail is what keeps water out, so it has to be compatible with the shingle profile.

Exposed-fastener panels. Common on barns and outbuildings, these take their own bracket types.

In every case, the roofing manufacturer and the solar installer should agree on the method in writing before work starts.

They can, if the mounting method is not approved or the work damages the roof. Most roofing warranties exclude damage caused by alterations made by others, and roof penetrations are the most common source of leaks.

For an Interlock roof, the Guardian Lifetime Limited Material Warranty from Interlock Roofing covers material and finish for the original purchaser while they own the home; workmanship is excluded, and so is work by others. Before you sign a solar contract, ask your roofing dealer and the solar installer to confirm the mounting method with the manufacturer in writing.

Also decide who is responsible for leaks at solar mounts. Usually that is the solar installer, under its own workmanship warranty. Get that in the solar contract. See metal roof warranties explained.

Not for homeowners installing new systems. IRS guidance on the 2025 federal law changes (Public Law 119-21) says the Residential Clean Energy Credit under Section 25D is not allowed for expenditures made after December 31, 2025. The IRS treats an expenditure as made when the original installation is completed, so a system finished in 2026 does not qualify even if it was paid for earlier.

The same guidance says the Energy Efficient Home Improvement Credit (25C) is not allowed for property placed in service after December 31, 2025.

If a solar salesperson mentions a tax credit in 2026, ask which code section it is and confirm it with a tax professional. Leases and power-purchase agreements are different arrangements from buying a system; read those contracts carefully. This information is current as of October 17, 2026.

Three sets of rules matter most.

• Your utility. Interconnection approval and how you are credited for exported power are set by your utility's tariffs, approved by the North Carolina Utilities Commission for investor-owned utilities. Rules for new customers have changed in recent years, so get your utility's current terms before you size a system.
• Permits and licensing. Solar arrays typically need building and electrical permits from your local inspections department, and the electrical work requires a licensed electrical contractor.
• Wind and HOA. In coastal areas with higher design wind speeds, mounts and the roof itself must meet the code requirement for your house. Many HOAs also review solar and roofing changes; see HOA metal roof approval and NC coastal wind zones.

It can, modestly. The U.S. Department of Energy explains that cool roofs, which reflect more sunlight and release absorbed heat, can lower roof temperatures and cooling demand in hot climates. Interlock colors carry Cool Roof Rating Council ratings, so you can compare reflectance between colors.

You may see older claims that a roof is ENERGY STAR certified. The EPA ended the ENERGY STAR roof products program on June 1, 2022, according to the Cool Roof Rating Council, so CRRC ratings are now the reference. Attic ventilation and insulation usually matter more than roof color; see does a metal roof make a house hotter and metal roof colors for NC heat.

Coordinating them is smart, but keep the contracts and responsibilities clear. Ideally the roof goes on first, the roofer installs or prepares the mounting points with approved flashing, and the solar installer follows.

Metal Roof NC's rule of thumb is that an Interlock aluminum roof typically costs about 2.5 to 3 times a traditional asphalt-shingle roof. Prices vary job to job with roof size, pitch, tear-off and other conditions, and an on-site estimate is required for an accurate price. Tell your roofer about solar plans at the estimate visit so layout, vents and attachment points can be planned. Request an estimate or read about Interlock roofing.
