This is what a valley is supposed to look like.  Each course runs all the way to the exposure line and you shouldn’t see any of the next slate hanging down.  If your valley cut is wider than a normal bond you use a slate that is larger than the rest of the field slates to run all the way in.

This is what field should look like.  Slates are laying flat, the bottom of the slate shouldn’t be canted up in the air.  Gaps at the bottoms of the slates like those shown in the photo below are usually a sign of over-nailing, poor decking preparation, or lack of a cant strip at the bottom.

This picture shows a job where Commonwealth Roofing, from Louisville, KY stripped a perfectly good peach bottom roof from this house and laid new slate.  There was some damage to the box gutters and a dormer from a tree fall, but it only required replacement of the copper work and a few courses of slate.  I’m sure they convinced the homeowner or the insurance company that the whole thing needed to be re-done.  I guess that would have been OK, but the work they did is terrible.  This is a “new” roof.  It is only a few months old.  Notice all of the slates that are not laying flush and the inconsistent exposures everywhere.  Also they didn’t run each course all the way into the valley.

More of the same junk.  These are not even the worst areas of this roof.

They convinced the homeowner or the insurance company that the whole thing needed to be re-roofed when really it just needed minor repairs. The original roof was better than what they got, even with the storm damage.
