Is my chimney flashing adequate? (photo)
I posted earlier about a recurrent roof leak. Two roofers came by yesterday. Neither performed any testing with a hose to check for a leak. One said that everything looked OK on the roof. The other said the flashing around the chimney was inadequate.
This flashing was just installed, and I have my doubts about whether it was done properly. This contractor claims that just by eyeballing the flashing he can see it wasn't done right. He wants to redo the whole thing and install "double flashing."
Here is a photo of the chimney:
It's a bit dark, but you can see the flashing pretty well in this cropped photo. My question is: is this contractor correct or is he trying to pull a fast one?
I'm not asking whether the flashing is OK, but whether you can tell by just LOOKING at this flashing that it is not OK.
