sure, as long as the old roof is still flat and not wavy or cupped and doesn't already have 4 or 5 layers of shingles on it. I've seen a lot of roofs with a couple of layers of shingles on them having no problems. Your local roofing contractor will say "hell no" because he'll want to do a tear-off and reroof and make a bit more money. If you can afford it, that is probably the best way to go, but if you want to save some bucks roof right over the old. It's common practice and should serve you well

When you install shingles over an old layer of shingles do you have to put down felt or do you put the new layer of shingles directly over the old layer?
With composition shingles, no felt is necessary between shingle layers. When the exposure of the shingles is the same as the old exposure, the bottom edge of the old shingles is used as a guide for the upper edge of the new shingles in placement. This ability to place the shingles would be lost if covered with felt.

How do you know when to replace a roof shingles?
Sooner or later, every roof needs to be replaced, usually due to the long-term effects of weathering. If a residential roof is more than 20 years old, it is a prime candidate for re-roofing.To determine if you need a new roof:On the ground, walk around your home with binoculars and inspect your roof for cracked, curled or missing shingles, as well as any excessive loss of the protective mineral granules. DO NOT CLIMB ON THE ROOF; walking on the roof is dangerous and can damage your roof.In your attic, take a flashlight and look at the underside of the roof deck and rafters for any stains or wet spots indicating water leaks.Asphalt shingles can often be applied directly over existing roofs without the necessity of tearing off the old roof. However, new shingles cannot be properly applied over hard or brittle materials, uneven surfaces for nailing or roof decks with warped, rotted or unsound support that should first be replaced or repaired.Some local ordinances forbid re-roofing over two or more layers of shingles. If a home already has been shingled several times, it is important to first determine if the roof deck can support another layer of shingles before undertaking any re-roofing project.
Can you install dimensional shingles over dimensional shingles?
Any time you layer on top of existing shingles you cut down the life span of the new roof. (Roof gets hotter and so the materials deteriorate faster.) So you may be able to do it (check local codes) but it isn't advisable. If you're looking to save, you may be able to do the tear-off yourself.

How do you add roll roofing under shingle roofing?
I am not sure if this question is worded correctly. 1) To add rolled roofing under shingles is not a recommended method of installation. What will work is to install a layer of Ice & Water Protection such as Grace Ice & Water Shield prior to the installation of your shingles. 2) If you meant to ask about installing rolled roofing over your shingles or installing shingles over your rolled roofing this is once again not recommended but is commonly done. You would first make sure the surface is level and remove all loose debris from existing roofing materials and or dirt, leaves, etc.. Just a quick clean up and sweep should be good. Then if the existing roofing materials are leaking I would recommend you either remove them and do this installation properly or at least install a layer of underlayment such as a heavy 30# felt paper or RoofTop Guard II over the existing materials. Then install the new materials following the manufacturers specifications. Once again this is not the recommended procedure and will void all manufacturers warranties.
