House got soaked during new roof

[John H.]

Had a friend call from VT yesterday, house was 90% rehabbed when they did the roof and were caught by a down pour. Its a 1945 story and a half house with slanted 2n't floor ceilings and no attic.

You can see most new tape joints as they are soggy, all lights filled up with water, outlets had water dribbling out of them, even basement had plenty of water dripping into it.

Ceiling under roof is blown in, ceiling on fist floor is 30 year old fiberglass. Most walls are a mix of blown in and fiberglass.

He asked what should he do. My first reaction was gut it back down to studs and let it dry. The way it is setup you cannot remove insulation without removing sheetrock.

I'm not a pro though, is there a way to salvage this without a fear of mold issues?

He has 3 fans and 3 dehumidifiers running, windows shut, all outlet cover removed, now waiting and seeing.

Thanks for any input.
