Different metals may require separation or specific compatibility measures when used together. Panels, fasteners, flashings, and equipment attachments should be reviewed as one assembly. A small accessory can matter even when the main roof material is appropriate.
What to do next
Ask the project team to identify potentially incompatible contacts and runoff paths. Follow the selected manufacturers' instructions for isolation and attachment. Do not add improvised metal brackets or patches without checking their relationship to the existing roof components.
