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.
