Sounds like a good time to go over a little ladder safety.
The proper tilt angle of an extension ladder is a 1:4 ratio...
or the feet are one foot out for every 4 feet of height.

Another good rule is "Always maintain 3 points of contact with the
ladder". A foot and two hands (while climbing or descending), two
feet and a hand, or two feet and a knee or hip (while working).
