Complex roofs contain more transitions, valleys, and penetrations than a simple roof plane. Those details affect system selection and installation planning. A material that works well in one geometry should not be chosen without reviewing another.
What to do next
Ask the contractor to explain the difficult details in each proposed option. Compare complete assemblies and fabrication needs. Keep visual preferences connected to the practical transition design so the selected covering can be detailed appropriately across the whole roof.
