The ridge is a distinct roof detail, not merely another row of field tiles. Attachment, joints, and transitions can differ from the main roof surface. Local ridge problems do not automatically establish failure across the entire roof.
What to do next
Ask the assessment to identify the affected ridge sections and the condition of adjacent tiles. A repair proposal should describe the complete ridge detail and applicable product instructions. Keep broad replacement recommendations tied to findings beyond a single visible defect.
