Which type of ladder is typically used for accessing rooftops?

The extension ladder is most commonly used for accessing rooftops due to its design and functionality. This type of ladder can be adjusted to various lengths, allowing firefighters to safely reach different heights as needed. The ability to extend the ladder makes it versatile for a variety of applications, particularly in emergency situations where quick access to a roof is required.

In contrast, folding ladders are generally more portable and designed for compact storage, making them less suitable for reaching higher structures like rooftops. Rooftop ladders, while they sound appropriate, are not standard terminology within firefighting; this term can sometimes refer to equipment designed for roof access in construction or maintenance contexts but is not widely recognized in firefighting practices. Attic ladders are designed specifically for accessing attic spaces in residential environments and do not typically reach the necessary heights for rooftops. Hence, the extension ladder is the most fitting choice for this purpose.
