What should be the horizontal distance in feet for a ladder to the wall?
The best tip I've come to is that for every four feet of height you have to climb, move the base one foot away from the wall. Better still is to have someone foot the ladder, or to fasten the ladder with a rope, preferably near the top of the ladder to avoid the ladder sliding sideways.

How does one use roof ladders outside the home?
A roof ladder or an extension ladder can be used for accessing the roof of one's home. One should take precautions when using a roof ladder to ensure safety. One should position the ladder so the bottom of the ladder is away from the wall one foot for every four feet in height it will be raised. The top of the ladder should be extended no more than four feet above the roof line. One should keep their body in the center of the rungs as they climb the ladder.
