I am building a small shed in the back yard from a plan I downloaded from the net. The plan completely skips over how to apply the roof. I am told it is a salt box style roof, it only has one side, kind of as though it were half a roof. The roof has a low end and a high end. I have no problem with flashing the low end but I am not so sure about the high end of the roof. I know its hard to understand based on the info I am providing but if anyone understand where I am coming from and has some insight into how you would flash the top, I would be most appreciative.

Well, I've only helped shingle one roof in my life so far, so I'm hardly an expert. However, a salt box roof is quite different than a shed roof, and a shed roof is what you seem to be describing in your post:
Normally, there won't be any metal flashing on the ridge of a gable roof, and so I can't see why you'd need any on a salt box roof. Instead, the shingles are cut at the notches to produce three tabs per shingle and these tabs are simply draped over the ridge of the roof and nailed down. Each of those tabs covers the nail heads holding the previous tab down. And the tabs are installed from one end of the roof to the other so as best to prevent rain from getting under the tabs when the wind is blowing in the prevailing wind direction, which is normally from west to east.
But, if you have a shed roof, then you're right... there should be some way of preventing a strong wind from blowing rain under the shingles at the very top edge of a shed roof.
It's not a very common kind of roof, so you might not get many responses in here. You might need to phone the local roofing suppliers in your area to see if there's a metal flashing specifically made for the top edge of a shed roof. But, it is a good question.This message has been edited. Last edited by: Nestor,

I use something like this to cap it off. I place the little curved part againt the fashia. You need to prebend so it's tight to the shingles and the fashia. I like the ones sold at Home Depot. There seamed (bent over on it's self) on both edges, which makes it stronger and less likly to cut you while working on it. I nail it up with white stainless steel trim nails, and only nail it in the fashia. That way there's no exposed nails on the roof. Do not use roofing nails or panel nails. There going to rust. Lowes and HD both sell Aluminum Trim coil nails in the siding area, which will work fine.
