My current roof is about 28 years old. It's in pretty good shape. No missing shingles or curling etc. There's a little discoloration on one edge.

If there is only one roof and its in pretty good shape, it isn't a bad idea to go over the top of it.
If the shingles are "cupped" then even though its not leaking, you should get it taken off. Leaking roofs can be replaced since you have to normally replace a sheet of plywood here or there due to the leak.

Install a standing seam metal roof with modern sunlight reflective coatings, and reduce your air conditioning costs. Also receive a $500 energy credit on your income tax through 2007. A metal roof generally does not require a "tear off" of one layer of asphalt shingles which saves you $5,000 for a 40 square roofing job. Also, they last 50 years. That's the good news. The bad news is that it will cost you double what a new asphalt shingle job will cost but remember, they last twice as long so you save in the long run if you don't kick the bucket first.

How many layers of shingles do you have on it, and what does your local building code allow? Some localities will allow up to three layers, but they have to be stripped off before you sell the house. Is the discoloration from a leaky roof or does the fascia/soffit need to be replaced?

You don't want to do that. Rip the old off for 2 reasons.
1 You can inspect and make sure the subsurface is sound and no damage is present. If any damage is spotted it can be fixed now for very little.
2 If you reshingle on top of old, the old will still harden and curl as the oil dries out of them. This will cause your new shingles to pop up and cause leaks.

Most states allow 2 layers of shingles for safety.In other words 3 layers poses a hazard.

I prefer to do a tear-off and re-roof.If you don't remove the old shingles and felt,you can't see any damage to the shingle side of the decking.Contractors prefer to do an overlay because it is faster and cheaper for them.

I know they reroof in the midwest over exhisting shingles ( well only one layer ) maybe you can't do it with newer types of shingles?

Most codes permit ONE course of shingles to be applied over one course of existing shingles. There's nothing wrong with it.

if there is nothing wrong with it just leave it alone. but if you do decide to go for it have them take it all the way down and put brand new stuff up. don't let them go over the old stuff. it just a bad idea.

In some states they are doing away with reroofs(added weight and fire hazard) but i think it will be ok .
