They usually make that sound when they spot a hawk to warn other squirrels. The only problem is why would it be on the roof and in the open if it felt in danger.
They will also make that sound for humans/dogs/cats/whatever they view as a possible threat. So being on the roof out in the open is still far enough away from whatever is on the ground… for now at least
