A toe-board or kick-plate is legally required if the perimeter edge of the roof does not feature a solid, permanent upstand or parapet wall that is at least 100mm high. According to UK health and safety guidelines, the purpose of a toe-board is two-fold: it stops an operative’s foot from slipping over the edge, and it prevents loose tools, fixings, or maintenance debris from being accidentally kicked off the roof onto people or property below. If your building has an existing coping stone or parapet higher than 100mm, standard handrails can be installed without an additional toe-board / kick-plate profile.
