Which of the following roofing systems is suitable for re-covering existing roofs?

Liquid applied systems are particularly suitable for re-covering existing roofs due to their versatility and ease of installation. These systems can be applied directly over the existing roofing material, creating a seamless, waterproof membrane that enhances durability and lifespan. Unlike traditional roofing materials, liquid applied systems can effectively accommodate minor imperfections in the underlying roof surface and provide a monolithic layer that minimizes the potential for water infiltration.

In addition, they can be used on a variety of surfaces, making them an excellent choice for re-covering applications. This characteristic minimizes the need for extensive preparation or removal of existing roofing materials, resulting in a quicker and often more cost-effective solution. Overall, the ability to create a strong bond with existing materials and enhance the roof's waterproofing qualities makes liquid applied systems a preferred option for re-covering existing roofs.
