I need your advice if possible.
We called a local contractor to give us a free estimate for a minor repair (a few shingles need to be replaced after a recent wind storm). He came over and quickly applied some kind of a temporary patch and told my wife that he would give as call to discuss this and then he left. The next day I noticed lots of dents on the garage roof that weren't there before. Apparently that's where he placed his ladder to be able to access the area that needed work. Here is the picture:
The arrow indicates the area that needed work. The white dots are the dents that I noticed.
Here's a couple of more detailed pictures of the damage taken from inside the house:
There are actually many more dents than seen on these pictures as if he needed to reposition his ladder a few times.
I have a few questions. Do the shingles look damaged badly enough that they need to be replaced? Can he claim that was the only way to reach the upper roof? Could have he avoided this? Can we hold him repsonsible for the damage he caused or that's normal? Shouldn't he have some kind of a stabilizer or a stand-off or whatever you call it to avoid resting the ladder directly on the roof? Why would he need to reposition his ladder so many times to apply a patch to cover such a small area (just a few missing shingles all in the same place)?
What I find frustraing is that we wanted him to just give us a free estimate and possibly replace maybe a dozen missing shingles, that's all. He hasn't done that yet but he has already damaged a dozen more :(
What woud you do in our place?
Your input is greatly appreciated.
