There was extensive water damage done to the ceiling and the husband thought that this might dry out okay, but I strongly encouraged him to call a water damage company to dry out/replace the ceiling and anything else that had gotten wet. I explained that if the water damage isn't professionally treated and mold develops later on, the insurance company will deny any claim. If the damaged areas are dried out professionally and mold develops for whatever reason, the water damage company is responsible for any mold remediation that may be necessary.
I also suggested contacting their insurance agent to make him/her aware of the problem in case they need to file a claim. Depending on the cost of the repairs to dry out the house, some people may choose to pay out of pocket since this would be less than their deductible for insurance.
I took before and after pictures of the water line that had leaked and wrote a detailed description of what had happened in my invoice. The damaged drywall that I removed and the leaking copper fitting were left behind for the insurance adjustor in case they need to file a claim.
