Metal roofs and solar panels are one of the best pairings in home energy — and NJ homeowners who invest in a metal roof before or alongside solar installation get the long-term benefit of both a roof that may outlast the home and a solar system with a 25-year production warranty. Here's what NJ homeowners with metal roofs need to know.
Standing seam metal roofs are the ideal solar substrate — clamp-based mounting attaches to the seams with no penetrations. Most NJ solar installers who work with standing seam roofs use S-5!, SnapNrack, or similar clamp systems.
Exposed fastener metal roofs (corrugated, R-panel, screw-down) require penetration-based mounting through the metal panels. These are still very compatible with solar but require careful flashing and sealant work to maintain waterproofness.
If you're replacing your roof and considering solar, doing both at the same time can reduce total cost — the roofing contractor and solar installer can coordinate on penetration points, structural blocking, and wire routing during the roofing phase. Some NJ contractors offer both roofing and solar, simplifying the coordination. The Home Service Guide can connect you with installers who handle combined projects.
