The roof at Guernsey Airport is to be covered in scaffolding for at least a year.
The scaffolding is to enable a full assessment and repairs to be carried out.
High winds have seen parts of the roof cladding fail.
Guernsey Ports Project Manager Joe Armstrong says the work is essential to ensure the longevity of the terminal building.
"The erection of scaffolding around the terminal building will allow for further ongoing maintenance while a detailed inspection of the roof's condition is undertaken.
This inspection will establish what options we have to safeguard and extend the usual life of the terminal roof cladding system.
It is anticipated that the scaffolding will be in place for at least 12 months but this is dependent on the outcome of the inspection and the time taken to undertake any repairs that are required."
The assessment will have no major impact on passengers or airport operations.
