A later that will reach a two and a half story roof?

To reach a two-and-a-half story roof, you will typically need a ladder that extends at least 20 to 25 feet, depending on the height of each story. Standard residential stories are around 10 to 12 feet high, so a ladder that can extend to 25 feet would provide enough reach with a safe working angle. It's important to ensure the ladder is stable and positioned on a flat surface for safety when accessing elevated areas. Always follow safety guidelines and use the appropriate ladder type for the task.
