Insurance Claim

I had a water infiltration in the annex ( extension of the house) when i was away, the water have running slowly for about a week . Vinyl floor (plywood) and the (sheetrock ) wall and ceiling on the floor below.
Right now the floor is still wet the vinyl bum out from the floor and the sheetrock are all wet .
I can’t evaluate at the moment until is all dry up the extend of the damage that have been done to the floor ,ceiling,wall.
I call the insurance right away to file up a claim they told me to call them back later on with more info about the damage.
Should i file up for a claim anyway and update later on ???.
I took pictures also to have some record of it.
Thanks
