Hot Melt Roofing

A Hot Melt Roofing System is a self-healing hot liquid roofing membrane that is applied directly to a pre-prepared surface, usually made of concrete. The system is monolithic, and the liquid is usually formed by a variation of materials such as Synthetic Rubbers, Refined Bitumen, fillers, and other products. Once the layer has been implemented, this can act as a rain-resistant material meaning the system is a guaranteed waterproof solution with long-term durability.

The best use of a Hot Melt System is applying it as an Inverted Roof System. This is when the hot Liquid Membrane is laid directly on the concrete slab of the roof, with the insulation and Waterproofing system below the concrete. Once this has been applied, the insulation is laid on top of the new layer. When thinking about a Hot Melt Roofing System, these are the advantages to consider;

• Waterproof – A Hot Melt Roof Membrane is rain, snow, and frost resistant
• Excellent adaptability to low temperatures – Can withstand temperatures as low as -18C
• A reliable, long-term system – It is designed to last a lifetime and is Ultra-Durable throughout
• Cost Efficiency and Fast Installation – Due to the long-term performance there is no need for a roofing replacement during the building’s life span
• Environmentally Friendly – The membrane materials are easily recyclable and there is hardly any packaging to dispose of

The roof also needs to be designed to support adequate overflow and drainage, and all thermal requirements and wind conditions must comply with the recommendations of BS 6229:2018.
