I am going to try to be as balanced as I can here, and I have made these comments to Shawn by phone.
On the positive side, Shawn was great to deal with, very personable, arrived before we did and was already on the roof when we got there.
The walk through was thorough overall, and the report was easy to read with lots of pictures and tips.
Where things went offside was when Shawn was reluctant to open the access panel to the jacuzzi tub as he was concerned about damaging the paint. Our agent and I weren't willing to give him permission to proceed, so it was left unopened.
Subsequent to moving in, and using the tub, we found water had leaked (we could see this from the ceiling immediately below). In order to attempt to assess the situation, I decided to open the access panel and found it came off with very gentle pressure. Once open, mold was easily seen and we immediately called someone to assist us.
Their assessment was that the issue had been ongoing for sometime, and they could see not just mold but what appeared to be fungus.
We had intended to replace the tub with a walk-in shower, which I did tell Shawn, but this forced us to have to do so much sooner than anticipated, and added approximately $1,000 of costs to remediate the issue.
Ultimately my issue is the failure of imagination on Shawn's part - whether we were going to replace the tub or not is irrelevant. As my wife said, he should have suggested we seek permission from the seller or the seller's agent to open the panel rather than balk at the risk of damaging the paint. I am not the home inspector, he is, and I shouldn't be expected to know what's important to look at.
I will note that these comments have the benefit of hindsight, but considering that water is one of the worst enemies of a home, I don't feel they are unreasonable.
