How high on a typical two-story building can a 24' - 28' ladder reach?

A 24 to 28-foot ladder is generally able to provide access to the roof of a typical two-story building when properly positioned. To understand this, it's important to consider the average height of residential buildings. A standard two-story home often ranges from about 18 to 24 feet in height, including the eaves and the slope of the roof.

When a ladder is extended and raised, the angle at which it is set up is crucial for safety and accessibility. Generally, a ladder should be set at about a 75-degree angle to ensure stability while maximizing its reach. If positioned correctly, a 24 to 28-foot ladder can indeed extend high enough to access the roof or provide an adequate height for firefighting and rescue operations.

The option indicating that the ladder can reach the second-story windows with two rungs inside is less accurate because it does not account for the additional height needed to safely land on the roof, especially in emergency situations where personnel might need to access a roof directly. Reaching just the windowsills or first-story windows does not fully utilize the ladder's potential height. Hence, the most logical outcome is that such a ladder can indeed reach the roof of a typical two-story structure.
