The main roof panel is only one part of a coastal assembly. Fasteners, flashings, trims, and equipment attachments also need suitable compatibility and exposure review. An appropriate panel choice does not make every accessory appropriate.
What to do next
Ask the contractor to identify the accessory specifications and governing documents. Review substitutions before installation. Keep the complete material list with the project record so maintenance work does not introduce incompatible parts later.
