Ridge and hip caps cover junctions between roof planes and may have their own product and attachment requirements. A field-shingle selection does not fully specify those components. Appearance and technical compatibility both matter.
What to do next
Ask for the proposed cap product and installation detail. Where ridge ventilation is included, review how the components work together. Confirm that the estimate covers the complete ridge or hip work rather than leaving these areas to an undefined substitution.
