I was kind of wondering if anything in your shed would be affected by the water running down the wall - as long as nothing was actually touching the wall and you have a deck that gets your stuff off the ground I would think it would be ok unless you're trying to seal out humidity as well. My preference is to not attach new to old unless absolutely necessary.
