Roof Ladders provide specialist access across a pitched roof when the work has been planned and the roof can support the equipment and user. They differ from ordinary leaning ladders because the upper end is secured over the ridge while load-spreading bearers contact the roof slope. MacBlair lists them within the wider ladder and access range. This spreads contact over the tiles rather than concentrating force on individual rungs.

Length must suit the roof from eaves to ridge without leaving an unsupported gap. Check the ridge hook or support, wheel operation, bearer condition and manufacturer's load rating before use. A separate, correctly secured extension ladder may be needed to reach the eaves. Never use the roof ladder itself as a bridge or rely on gutters as a load-bearing rest. Confirm the ladder can be moved into position without standing on the roof edge.

Roof Ladders do not make a fragile roof safe. Assess roof condition, pitch, weather, edges, openings and the risk of falling materials before work begins. Roll the ladder up the slope only as directed, turn it into position over the ridge and check that it sits evenly. Edge protection, fall prevention or other access equipment may still be required under the work-at-height plan. Fragile rooflights should be treated as openings even when their surface looks sound.

Keep roof surfaces free from loose tools and avoid work in high winds, ice or other conditions that affect footing or equipment stability. A specialist ladder must be inspected before every use and removed from service if hooks, rungs, stiles or bearers are damaged. The site health and safety range can support wider controls identified by the job assessment. Plan how tools will be raised so climbing hands remain free.
