Missing shingles warrant assessment of the exposed layers and nearby roof details. The visible gap is not a complete measure of damage. Storm conditions can affect other portions of the roof that are harder to see.
What to do next
Stay off the roof and document safely visible conditions. Ask the contractor to distinguish immediate protection from permanent repair. The repair scope should identify the affected assembly, not merely the number of replacement shingles.
