Whether classified to be Fragile or non-Fragile, rooflights should be considered dangerous areas. "Brightly coloured" fixings should be used to assist in the location of the rooflights, and colour identified. Poppy red has become the industry's norm. It is highly recommended that all fixings around rooflights are colour capped or moulded in poppy red.
