Solar is built to last decades. Too many roof mounts aren’t.
Roof Mounting Shouldn’t Be the Weak Link.
Installers know the drill:
-
Penetrations that turn into leaks
-
Rust and corrosion over time
-
Wind stress loosening hardware
-
Callbacks for maintenance
-
Labor-heavy installation systems
Every weak mount becomes a future problem. And future problems cost money.
