Torch down roofing consists of modified bitumen, a combination of asphalt and rubber or plastic polymers, which is heat-welded to create a seamless, waterproof barrier. The installation process uses a torch to melt and bond the roofing material onto the surface, ensuring superior adhesion and strength.
Torch down is commonly installed on:
✅ Industrial Facilities – Warehouses, distribution centers, and factories.
✅ Retail Buildings – Malls, shopping centers, and standalone stores.
✅ Office Complexes – Low-rise and high-rise commercial buildings.
✅ Healthcare & Education Buildings – Hospitals, schools, and universities.
✅ Multi-Family & Mixed-Use Buildings – Apartments, condos, and commercial spaces.
There are two main types of torch down roofing based on the type of modified bitumen used:
🔹 APP (Atactic Polypropylene) Torch Down – More flexible and UV-resistant, making it ideal for warmer climates.
🔹 SBS (Styrene-Butadiene-Styrene) Torch Down – Offers greater flexibility and elasticity, making it better for buildings in areas with temperature fluctuations.
The installation process involves:
1️⃣ Surface Preparation – Ensuring the roof is clean and primed.
2️⃣ Base Sheet Installation – Securing the first layer to provide stability.
3️⃣ Torch Down Application – Using a propane torch to heat and bond the modified bitumen layers.
4️⃣ Sealing Edges & Flashing – Reinforcing seams and penetrations for extra waterproofing.

If you need a long-lasting, highly waterproof, and weather-resistant roofing system for a flat or low-slope commercial building, torch down roofing is an excellent option. It provides strong protection against leaks, UV rays, and heavy foot traffic, making it a smart investment for property owners looking for durability and performance.
