Can I install composite roofing shingles myself?

The last time the roof needed work, I did it myself. However, this time it looks like we need a whole new roof. I would love to do it myself to save money, but I am not sure whether or not this is possible. We have decided that we want to put in composite roofing shingles, and I think that I might remember hearing the these should be installed by a professional roofer. Can anyone tell me where I can find out more about composite roofing shingles and how they are installed? I would love any advice anyone can give me.
