What is Torch Down Roofing?

Torch-down roofing is a durable and reliable roofing system often used for flat and low-sloped roofs. It consists of layers of modified bitumen applied using heat, which creates a waterproof and seamless barrier. This roofing system is known for its resistance to extreme weather conditions. It offers long-term protection. It’s an ideal choice for both commercial and residential buildings that need a sturdy, low-maintenance roof.​

What are the components and materials of torch-down roofing?

Torch-down roofing is made from a combination of materials designed to provide durability, flexibility, and water resistance. Below are the key components and materials used in the system:

• Modified Bitumen: Modified bitumen is the primary material used in torch-down roofing, made by combining asphalt with polymers. This gives it added flexibility, heat resistance, and long-lasting durability. It creates a strong, waterproof membrane that protects the roof from leaks and water damage.
• Fiberglass or Polyester Reinforcement: These materials are used as the base reinforcement layer within the roofing system. They add strength and flexibility, preventing tears and ensuring the membrane can expand and contract with temperature changes. The reinforced mat also helps the roof withstand wear and tear over time.
• Adhesive Layer: The adhesive layer binds the modified bitumen to the roof deck. It is applied using heat from a propane torch, which activates the adhesive, creating a solid bond between the roof membrane and the deck. This layer ensures that water cannot seep beneath the roofing material.
• Mineral Granules: Mineral granules are added to the top of the roofing membrane to offer UV protection and improve durability. These granules also provide a finished appearance. It helps protect the roof from sun damage, reduces heat absorption, and increases the overall lifespan of the roofing system.
• Flashing: Flashing is used around roof penetrations, such as vents or chimneys, to prevent water from leaking through seams. It helps create a watertight seal at critical points on the roof, which ensures that moisture does not get trapped in vulnerable areas. Flashing is typically made from modified bitumen or metal.
• Protective Coating (Optional): A protective coating can be applied to the top layer of the torch-down roofing. This coating helps improve the roof’s resistance to UV rays, which reduces the effects of sun damage. It also provides added protection against environmental elements and increases the lifespan of the roof.

Common Torch Down Roofing Problems and Solutions

Torch-down roofing is a highly durable system, but like any roofing material, it can experience problems over time. Understanding these common issues and knowing how to address them can help prolong the lifespan of your roof. Below are some of the most common problems with torch-down roofing, along with their solutions.

• Leaks at Seams: Leaks often occur at the seams where two sheets of modified bitumen meet. These seams can weaken over time, allowing water to get inside.
• Solution: Inspect the seams regularly and reseal any gaps with a high-quality bitumen sealant. If necessary, use a propane torch to melt and reseal the seams.
• Blistering: Blistering can develop when air or moisture becomes trapped under the roofing layers. This creates bubbles or blisters that can eventually burst. It causes leaks.
• Solution: To fix blistering, carefully cut the blister open, remove any trapped moisture, and patch the area with a new layer of modified bitumen. Ensure the area is properly sealed.
• Punctures and Tears: Punctures and tears may occur from sharp objects or heavy foot traffic. These weak points can lead to water infiltration.
• Solution: Patch small punctures by cutting a piece of modified bitumen, then apply adhesive, and securely bond it to the damaged area. Larger tears may require a full repair with a new layer of bitumen.
• Granule Loss: The loss of mineral granules from the top layer can lead to UV damage and premature wear. This usually happens due to age or extreme weather conditions.
• Solution: If granule loss is significant, consider applying a new layer of modified bitumen with granules to restore the protective surface. This will also help improve the roof’s UV resistance.
• Cracking: Cracks in the roof surface can develop from exposure to extreme temperature changes, which cause the material to expand and contract. These cracks allow moisture to penetrate.
• Solution: For cracks, use a high-quality roofing adhesive or sealant to fill the gap. It is important to monitor the area for any further damage and reseal as needed.
• Improper Installation: If the roofing system is not installed properly, it can lead to various issues, including poor adhesion and water leakage.
• Solution: To fix improper installation, hire a professional roofing contractor to reapply the system correctly. Proper installation is key to ensuring long-term roof performance.
• Standing Water: Water pooling or standing on the roof can result in leaks and membrane damage. This problem usually occurs on flat roofs where drainage is inadequate.
• Solution: Check for proper drainage by ensuring that the roof slope is correct. If necessary, add drainage systems or reconfigure the roof slope to ensure water flows off properly.

How to Install a Torch Down Roofing System

Torch-down roof installation involves several key steps that ensure a durable and watertight result. While it is best left to professionals, here is an overview of the installation process for those interested in understanding the steps involved.

• Prepare the Roof Deck: Begin by thoroughly cleaning the roof deck. Remove any debris, old roofing materials, and dirt that could prevent proper adhesion. The surface should be dry, smooth, and clean to allow for a strong bond.
• Install the Base Sheet: Unroll the base sheet of modified bitumen over the roof deck. Heat it with a propane torch to activate the adhesive and bond it to the deck. The base sheet forms the foundation of the roofing system and provides stability.
• Apply the First Layer of Bitumen: Once the base sheet is in place, unroll the first layer of modified bitumen. Heat it using the torch, which allows it to fully adhere to the base sheet. Be careful to avoid overheating, as this can damage the material.
• Lay Additional Layers: If using a multi-ply system, apply additional layers of modified bitumen. Each layer must be thoroughly heated and bonded to the layer beneath it. Ensure that each layer overlaps the previous one to maintain a seamless, waterproof seal.
• Seal the Seams: After applying the layers, focus on sealing the seams between the sheets. Use a torch to heat the seams and press them together to ensure a watertight bond. This step is crucial for preventing leaks at the joints.
• Apply Flashing Around Penetrations: Flashing should be installed around roof penetrations such as vents, chimneys, and skylights. The flashing should be sealed with modified bitumen to prevent water from seeping into these vulnerable areas. Ensure all edges are properly sealed.
• Finish with the Top Layer: Finally, apply a top layer of modified bitumen with granules or a reflective coating. This will provide UV protection and a finished appearance. The top layer also protects the roof from environmental damage and helps reflect sunlight, thereby reducing heat.

How to Repair a Torch Down Roof

Repairing a torch-down roof requires careful attention to ensure that the roof remains watertight and durable. Below are the steps for fixing common issues that might arise with torch-down roofing.

• Locate the Damage: The first step is to identify the damage, such as leaks, cracks, or punctures. Inspect the roof carefully, and check seams and areas with visible damage. Mark the problem areas for easy reference.
• Clean the Damaged Area: Before making any repairs, thoroughly clean the damaged area. Remove dirt, debris, or old roofing material from the damaged section. This ensures proper adhesion for the new materials.
• Cut and Prepare the Patch: Cut a piece of modified bitumen that is slightly larger than the damaged area. Use a utility knife to trim the patch to fit the exact shape of the damage. Ensure the edges of the patch overlap the damaged area to achieve a secure bond.
• Apply Adhesive: Apply a layer of roofing adhesive or heat the area with a propane torch. The adhesive will bond the patch to the roof surface. Be careful not to overheat the material, as this can cause further damage.
• Place the Patch: After applying the adhesive, position the patch over the damaged area. Press down firmly to ensure the patch is securely attached. Allow the adhesive to cure according to the manufacturer’s recommendations.
• Seal the Edges: After the patch is in place, seal the edges of the repair with a roofing sealant. This will help prevent water from seeping under the patch. Make sure the sealant covers the entire perimeter of the patch.
• Inspect the Repair: After the repair is complete, inspect the patched area to ensure it is secure and stable. Check for any signs of leaking or gaps. Perform a water test to verify that the repair is watertight and effective.
