Well now. Good timing on this thread. I just started a new deck project on my house. The old deck was too small and we needed a screen room. So I proceeded to take down the old deck. I removed the ledger board, which was simply nailed to the siding. No flashing, no bolts, nothing to stop water penetration into the sill. The siding basically was mush. I could almost wring water out of it if I tried. So, anyway, this is what I found. I now have to cut back the siding and sheathing, cut out the band joist and replace the sill. Oh yah!

Get someone out there to get rid of those little B--t-r-s......
