What is the tallest ladder one can get for home use?
A forty foot extension ladder is generally the largest you can find. The top of the ladder really only hits 37 feet, and obviously, you'd be standing below that at about the 30 foot mark. That's about 3 stories. The maximum height ladder is basically the biggest ladder that is available to the home owner. Generally a 40 foot ladder is the largest available for a reasonable price. This ladder is tall enough to meet most home owners needs.

The top of a ladder must extend how many feet above the surface a worker is climbing onto?
From the US OSHA Construction standards:1926.1053(b)(1)When portable ladders are used for access to an upper landing surface, the ladder side rails shall extend at least 3 feet (.9 m) above the upper landing surface to which the ladder is used to gain access; or, when such an extension is not possible because of the ladder's length, then the ladder shall be secured at its top to a rigid support that will not deflect, and a grasping device, such as a grabrail, shall be provided to assist employees in mounting and dismounting the ladder. In no case shall the extension be such that ladder deflection under a load would, by itself, cause the ladder to slip off its support.

What is the minimum length of a ladder required to access a roof surface 12 feet off the ground?
You should normally have three rungs(steps) past the surface you are climbing to from the ladder. They are a foot apart on most ladders so 15 feet would be close. Add a foot since you have to angle the ladder appropriately(scope) so 16 feet or longer is safe. A 20 foot extension ladder would be a good choice.
