I just got new siding on my house and I want to put a deck on. Is it ok if I bend the flashing up a little bit? Will this cause the OSB sheeting to rot?
I've attached an image to better show what I mean. On the left side of the image it shows the OSB sheeting (black vertical bar), the treated ledger board (white box), the blue siding and the metal flashing.
On the right it shows what I did to install my deck.
I was told after the fact that I should have just put the decking on top of the flashing but I had already put down my expensive composite decking. Pulling the board up would not be the easiest task and would cost me but I don't want the sheeting to rot either.
I personally don't see how rain or melting snow would cause the water to creep up in between the siding and the flashing to rot the OSB.
Please give me your opinion on this matter, thanks!
