Torch on Membrane

Torch on membrane is a type of roofing system that involves the application of multiple layers of modified bitumen sheets to create a waterproof and durable surface. This method is commonly used in flat or low-sloped roofs, where traditional roofing materials like shingles are not suitable.

The torch on membrane system consists of several components. The base layer is typically made of fiberglass or polyester, which provides strength and stability to the roofing system. On top of the base layer, multiple layers of modified bitumen sheets are applied. These sheets are made of asphalt mixed with polymers or rubber modifiers, which enhance their flexibility, durability, and resistance to weathering.

The installation process of torch on membrane involves heating the bitumen sheets with a torch to activate their adhesive properties. The heated bitumen is then applied to the roof surface, creating a strong bond between the layers. The seams between the sheets are also heated and fused together to ensure a watertight seal. This torch-on method allows for precise application and ensures a seamless and continuous roofing surface.

Torch on membrane offers several advantages over traditional roofing systems. Firstly, it provides excellent waterproofing capabilities, as the multiple layers and fused seams create a barrier against water infiltration. This makes it highly suitable for areas with heavy rainfall or extreme weather conditions.

Additionally, torch on membrane is resistant to UV radiation, which can cause degradation and premature aging of roofing materials. The modified bitumen sheets are designed to withstand prolonged exposure to sunlight, ensuring the longevity of the roof.

Moreover, this roofing system is highly durable and can withstand foot traffic, making it suitable for roofs that require regular maintenance or access. It also has good resistance to fire, as the bitumen sheets are self-extinguishing and do not contribute to the spread of flames.

In terms of maintenance, torch on membrane roofs are relatively low-maintenance. They require periodic inspections and cleaning to remove debris or vegetation that may accumulate on the surface. Additionally, any damaged or worn-out sections can be easily repaired or replaced without having to replace the entire roof.

Overall, torch on membrane is a reliable and cost-effective roofing solution that provides excellent waterproofing, durability, and resistance to various weather conditions. Its versatility and ease of installation make it a popular choice for commercial and residential buildings with flat or low-sloped roofs.
