How to Install Torch Down Roofing: A Fast-Track Guide to Mastering Torch Down Roofing in 1 Minute
Torch down roofing is a popular choice for flat or low-sloped roofs, appreciated for its durability and water resistance. This method uses modified bitumen sheets that are heat-welded to the roof surface using a propane torch, creating a seamless and robust waterproof barrier. Here’s a step-by-step guide to installing torch down roofing safely and effectively.
Step 1: Prepare the Roof Surface
Start by removing any existing roofing materials, debris, and dust from the surface. Check for any structural damage and repair as needed. A clean and smooth substrate is essential for proper adhesion.
Step 2: Apply the Base Sheet
Roll out a base sheet (usually nailed or adhered) over the roof deck, ensuring it fits snugly across edges and openings. This layer enhances insulation and provides a stable surface for the torch down membrane.
Step 3: Install the Torch Down Membrane
Unroll the modified bitumen membrane over the base sheet. Using a propane torch, heat the underside as you press the material onto the roof. The heat melts the bitumen, creating a strong bond with the base layer. Work slowly and carefully to prevent overheating, wrinkles, or gaps.
Step 4: Seal the Seams and Edges
Overlap seams by at least 3-4 inches and use the torch to bond each overlap and edge, ensuring watertight joints. Pay special attention to penetrations and flashings for complete waterproofing.
Step 5: Inspect and Maintain
After installation, inspect the entire roof for proper adhesion, coverage, and sealing. Routine maintenance, such as debris removal and checking for punctures or cracks, will help prolong the roof’s lifespan.
