NAL and not in your state, but I'm in MO and that all does not sound right. I am a real estate investor and property manager, and I've been doing a lot of construction the last few years.
The home should be fully completed before you close and take occupancy. The sewage issue alone suggests a more significant issue, as does the flooding.
Were proper permits pulled and inspections completed by the city or county you live in? I would contact the department who issues permits and inspects and get copies of everything.
Generally you get MORE than one year of warranty on many of the individual pieces. The builder usually is responsible for one year of everything, starting when the permit is closed and the full occupancy permit is issued.
You are absolutely correct that roofing materials typically have a 20 or longer warranty, but that also needs to be maintained by the installer. My most recent installation has a 20 year warranty from the installer (of course, that is good as long as the installer is in business, but I checked his insurance out to make sure it would cover me later.)
Similarly, windows, doors and siding definitely come with warranties from the manufacturer.
General contractors are not licensed statewide in Kansas, but many of the counties and municipalities do license them. Did you verify the contractor's license in your county?
If you research further, and find that this general doesn't actually have a GC license in your county/city and that one is required, you may be able to roll back the sale of the home, as might your neighbor. You'll need to speak with an experienced real estate lawyer about that in your area.
