Mike....
You do know that under the new NC RE Purchase Contract the inspector and the buyer are responsible for any damage incurred during the inspection? Some Realtors I deal with are marking out this clause in the contract. I am more careful now than I was a year ago about damage to a property.
Also...I have a concrete bed shower in my own second floor bath that I installed 10 years ago and had no leaks. If a HI came to my house and created a leak he would have a serious problem!
And yes...it is HOTTT at my house! 96 in the shade. I am replacing a rotten window sill under a four window assembly and watching the horse race....Big Brown is awesome!
