That one's clearly screwed up and likely to cause trouble. I'd recommend replacing it too. Then I apologize if I mischaracterized your report. If the sellers agreed to do it, then they should honor their agreement. Fair enough. There are times - like the example in the picture that you posted - where it can be a real issue. In my opinion, though, it's just not a real issue in most cases. Thanks Brandon. Thanks for your response Jim, I completely agree, there are multiple factors that will inevitably decide if this ever becomes an issue down the road. As you know, exposure/ roof protection/ maintenance all will decide on whether on not this issue eventually becomes water damage. There were at least a 1/2 dozen different places on the outside of the home that had similar (maybe not as extreme) curling and lifting like the picture shown. My concern is that moisture streaming down the wall on a rainy day, is then going to intersect with the reversed metal and leak horizontally. No end-damming (or seams on the belly-bands) to me seems likely that some of this moisture will then have a path behind the siding and potentially cause water damage. Now you mentioned that you would agree the example I gave needs replaced- if you see 6 or so places like this, will you only specifically mention those exact locations need repairs or replaced? Or do what I did, and recommend a specialized contractor provide a further overall evaluation to determine the need for repairs/ replacement? As far as the marble goes, it doesn't have alot of practical application in most situations. But for me, when these horizontal flashings (that were put there to direct water away from the wall- shingling principle right) are curled and lifted (not the way they were installed), I want my clients to know that it is performing opposite of what it was put there in the first place for (isn't that what happened with LP). The ball bearing makes explaining the situation to my clients much easier. Don't use it, if you don't like it. It makes showing the issue in a photo much easier.
