I would not waste my time bringing it to a dealer. Without x ray vision no one will be able to see the extent of the damage. If you heard wood crack, something is broken. Pooling water is never good on a trailer, especially if it is near any seams in the roof. These roofs are not hard to replace, just don't purchase your products from an RV dealer as it will cost a small fortune. When I was replacing my roof the dealer wanted $800 for twenty five feet of 7mil RV roof material. I paid $100 for thirty feet of 30mil commercial rubber roofing and another $75 for a five gallon bucket of adhesive.
