If a flat roof becomes leaky, a second vapour barrier is often the simple and most cost-effective solution. Due to ageing, climate and environmental influences, flat roofs are often damaged in their substance and functionality. Brittleness, cracks, welts, wrinkles and leaks in the vapour barrier require repair or thorough renovation measures.
