The torch-on method is a roofing and waterproofing technique that uses a heat-applied bituminous membrane to create a sealed, water-resistant layer on a roof surface.

In this method, sheets of modified bitumen (a rubberized asphalt material) are laid onto the roof. A gas torch flame is then applied to the underside of the membrane, heating it until the bitumen softens and becomes adhesive. As it melts, the membrane is pressed onto the roof surface, bonding tightly and forming a continuous waterproof barrier.

Once installed, the membrane creates a durable, flexible, and seamless layer that protects the roof from water penetration, UV exposure, and weather damage. It is commonly used on flat or low-slope roofs in both residential and commercial buildings.

Brush-applied rubber sealing is a manual method of waterproofing a roof using a liquid rubber coating applied with a paint brush.

In this process, the rubber sealant is dipped and spread directly onto the roof surface using a brush. The material is worked into the surface, allowing it to penetrate small cracks, joints, and porous areas. Because it's applied by hand, the installer has better control and can focus on problem areas like corners, edges, and leaks.

As the coating dries, it cures into a flexible, rubber-like membrane that bonds to the roof. This creates a waterproof barrier that prevents leaks while remaining elastic enough to handle expansion and movement.
