According to a recent article in roofing contractor.
Transition from ladder to roof.
You want to make sure the ladder is placed at the correct angle 75 5 degrees.
Falls are very likely to happen during this transition.
Staying safe during transition moving from the ladder to the roof is a very serious safety concern.
Having it extend any more or less can lead to the ladder slipping from the roof or the operator having difficulty getting onto the roof.
It requires no tools drilling or bolting to install and is one of the most effective means of improving the safety of nearly any ladder.
This is precisely the same procedure you should take when you are moving back to the ladder from the ceiling.
Move the other leg on the roof such that both your legs are on the roof.
While the transition make sure you never climb to the top most step of the ladder.
Transition to the roof once you reach the top of the ladder it s time to move on the top of the roof from the ladder.
You also want to make sure the ladder extends three feet above the roof line.
The first step is setting the ladder up properly.
