A key concept for safe school roof design is to minimize accessibility both to the roof and in the school from entry points on the roof. Avoid the use of permanent mounted roof access ladders, short walls adjacent to low canopy roofs, screen walls and columns using decorative block or wrought iron (open) framing that make climbing up to roofs easy.
Skylights are often used to gain entry to the interior of school buildings. While it is difficult to prevent them from being vandalized, access can be minimized by the use of multiple mullions. Solid or fixed diffusers within the light well can prevent further ingress into the building.
Equipment enclosures should protect roof equipment, such as HVAC cooling towers, from vandalism. They should have lockable louvered doors, and spaced sufficiently from the equipment to allow proper ventilation.
Parapets should allow for surveillance from the ground by restricting their heights or by integrating openings.
