Roof waterproofing is the process of applying waterproof materials and/or coatings to protect the roof from prolonged sun, rain, and extreme climate exposure. This ensures the roof does not develop cracks (that encourage water seepage) and prevents any porous materials from coming in contact with moisture.

APP stands for Atactic Polypropylene. APP membrane is the most commonly used waterproofing material on concrete roofs and low-slope roofs. APP membrane is applied to asphalts with a torch. Applications of APP membranes aren't limited to just roofs.

Waterproofing is the process of making an object or structure waterproof or water-resistant so that it remains relatively unaffected by water or resisting the ingress of water under specified conditions.
