A roofing membrane is a waterproof layer used to protect buildings from water damage. It is typically made from materials like rubber, thermoplastic, or modified bitumen. These membranes are installed on flat or low-slope roofs to prevent leaks and ensure durability against weather conditions. Roofing membranes can be either single-ply or multi-ply systems. Single-ply membranes are lightweight and easy to install, while multi-ply systems offer added strength and insulation. Proper installation and maintenance of a roofing membrane are essential for maximizing its lifespan and effectiveness in safeguarding the structure beneath it.
