When I purchased my property, the owner left his NorthStar 8000 generator. He built a shed for the generator that is pretty good, except for the roof. It is currently a flat, shingled roof that I assumed leaked because he tarped it and weighted it down. I am hoping to get some advice on the best and most efficient way to replace the roof and make it so it wouldn't be prone to leaking.

Is it the little barn roof beside the big shed? If so, I bet you could overlay the current roof with roofing metal. You can buy it in custom lengths from your bucking supplier. Make a drawing of the roof with measurements, length of ridge, length along sides, pitch of each section, and take a picture tsn off to a good building supplier. Make sure you check the existing framing for rot before you cover it up. Stripping off the shingled us a good idea as the granular stuff can cause some problems with the metal. If rot in roof then remove and you can recover with plywood and metal roof

Correct, the generator is the little building to the far left. I thought about using roofing metal, but wasnt sure if that would be the best method.

The other thing to note is that the roof is flat - so not sure if that changes how i should look to replace.

Metal roofing won't work on a flat roof. Generally metal needs at least a 2 in 12 pitch to drain, hopefully more. If you need a down and dirty flat roof, use torch down. You'll need a large propane torch to do so but it's the easiest way to seal a flat surface. Can't quite see what's going on in your pics, hard to believe someone would put shingles on a flat roof, but if so, now you know why it leaked.

I wish I had a better picture, but it is definitely shingled and flat. Is there a simple way to add pitch to the existing structure? Will hopefully be back up in a few weeks and can take a better picture. The tarp seems to be working, but is aesthetically difficult on the eyes. Would like to come up with a better solution.

You know a generator shed doesn't necessarily have to stay perfectly dry, so maybe metal will work for you. Putting pitch on the roof means rebuilding it. Have you thought about rebuilding the whole thing with a better design?

If it was me, I'd just rip the shingles off and then stick a 2x8 in the middle and frame two slopes off of it with 2"x2"s and cover with thin plywood and then put metal on that.
The local place I got my metal roof from had lots of off cuts that would work that then sell super cheap.

If it were me, I'd remove the shingles and roof frame. Inspect to make sure you can use the old roof (you said it might be leaky?).
Then I'd raise the front by a foot or two, re-install roof frame (old if still OK, otherwise a new one) and simply have a downward slope to the back (make sure it's drained properly).
You might have a ft or two of siding to find that sorta matches the current siding though. Kijiji or craistlist can probably help you with that if you need just a couple of boards...
