Wakaflex is a non toxic flexible, self-adhesive flashing designed to replace lead in most modern roofing applications. This lead alternative can be stretched over details whilst dressing to give a smooth, neat and premium lead-like appearance. Wakaflex is BBA approved and stretches up to 50% in length and 15% in width when dressed into the pan of the tile. It comes with perforated release paper, for easy application. Wakaflex is available in lead grey and anthracite, as well as 5 lengths and 2 widths.
