Torch Down Roofing

Torch Down Roofing: The Ultimate Guide for Residential and Commercial Applications

Torch Down Roofing

When it comes to protecting your home or commercial building, especially if it has a flat or low-slope roof, choosing the right roofing material is crucial. Among the various options available, torch down roofing stands out as a highly durable, waterproof, and long-lasting solution. At Chase Construction Northwest, Inc., we have extensive experience installing and maintaining torch down roofing systems, making us the go-to roofing contractor in Seattle and the surrounding areas.

What is Torch Down Roofing?

Torch down roofing, also known as modified bitumen roofing, is a type of roofing system that involves applying a rubberized membrane modified with Atactic Polypropylene (APP) weatherized asphalt. This roofing material is recognized for its exceptional strength, flexibility, and waterproofing capabilities. Torch down roofs are particularly popular in regions with heavy rainfall and fluctuating temperatures, like Seattle, due to their ability to withstand harsh weather conditions without compromising the integrity of the roof.

How Torch Down Roofing Works

Understanding the Layers: A Breakdown of Materials

Torch down roofing systems consist of multiple layers, each contributing to the overall durability and performance of the roof. The key components include:

  • Base Sheet: The base sheet is the foundation of the torch down roofing system. It is typically made of a non-woven polyester mat that provides strength and stability to the roof.
  • Cap Sheet: The cap sheet is the top layer, available in either smooth or granulated finishes. It is adhered to the base sheet using a roofing torch, ensuring a strong bond that enhances the roof’s waterproofing and weather resistance.
  • APP-Modified Bitumen: This rubberized asphalt is infused with Atactic Polypropylene, a thermoplastic polymer that increases the roofing material’s flexibility, allowing it to expand and contract with temperature changes without cracking.

The Installation Process: Step-by-Step

Installing a torch down roofing system requires expertise and precision to ensure a long-lasting and effective result. Here’s a step-by-step overview of the installation process:

  1. Roof Preparation: Before installation begins, the roof surface must be thoroughly cleaned and inspected for any damage. Debris, old roofing material, and moisture are removed to create a smooth, dry surface.
  2. Laying the Base Sheet: The base sheet is rolled out across the roof and heated using a roofing torch. The heat activates the adhesive properties of the material, allowing it to bond securely to the roof deck.
  3. Applying the Cap Sheet: Once the base sheet is in place, the cap sheet is applied in a similar manner. The cap sheet can be either smooth or granulated, depending on the desired aesthetic and functional requirements. The roof torch is used to adhere the cap sheet to the base sheet, creating a seamless and durable roofing system.
  4. Sealing and Finishing: The final step involves sealing the edges and ensuring that all seams are properly fused. This step is crucial for preventing water infiltration and ensuring the roof’s long-term performance.

Types of Torch Down Roofing

Single-Ply vs. Multi-Ply Torch Down Roofing

Torch down roofing systems can be classified into single-ply and multi-ply systems:

  • Single-Ply Torch Down Roofing: This system consists of a single layer of membrane. It is quicker to install and more cost-effective but may offer less durability compared to multi-ply systems.
  • Multi-Ply Torch Down Roofing: Multi-ply systems involve multiple layers of membrane, typically a base sheet followed by one or two cap sheets. This configuration provides enhanced durability, making it suitable for commercial applications or areas with extreme weather conditions. These come in various colors, some of which are Energy Star rated and qualify for the Federal tax credit, offering better energy efficiency and potential tax credits.  

Base and Cap Sheets: What You Need to Know

The base and cap sheets are integral to the torch down roofing system:

  • Base Sheet: Acts as the foundation and provides structural stability.
  • Cap Sheet: Provides the final layer of protection and can be chosen based on specific needs, such as energy efficiency or aesthetic preferences.

Benefits of Torch Down Roofing

Why Choose Torch Down Roofing?

Torch down roofing offers several advantages that make it an attractive option for both residential and commercial properties:

  • Longevity and Durability: The rubberized membrane is highly durable, capable of withstanding extreme weather conditions without cracking or deteriorating. A well-installed torch down roof can last 15 to 20 years or more with proper maintenance.
  • Waterproof and Weather-Resistant Features: Torch down roofing is renowned for its waterproofing capabilities, making it ideal for areas with heavy rainfall. The seamless installation process ensures that water cannot penetrate the roof, preventing leaks and water damage.
  • Suitable for Flat or Low-Slope Roofs: Torch down roofing is specifically designed for flat or low-slope roofs, providing a reliable solution where other roofing materials may not perform as well.
  • Energy Efficiency and UV Resistance: Granulated torch down membranes can reflect solar rays, helping to keep buildings cooler in the summer. This energy efficiency can lead to significant savings on energy bills over time.

Torch Down Roofing vs. Other Roofing Options

Torch down roofing is often compared to other popular roofing materials, such as EPDM, TPO, and asphalt shingles. Here’s how it stacks up:

  • EPDM Roofing: While EPDM (Ethylene Propylene Diene Monomer) is another popular choice for flat roofs, torch down roofing offers superior durability and resistance to punctures. EPDM is more prone to damage from falling debris, while torch down roofing provides a thicker, more robust surface.
  • TPO Roofing: TPO (Thermoplastic Olefin) roofing is known for its energy efficiency and ease of installation. However, torch down roofing offers better longevity and is more resistant to extreme weather conditions, making it a better choice in regions like Seattle.
  • Asphalt Shingles: While asphalt shingles are a common choice for sloped roofs, they are not suitable for flat or low-slope roofs. Torch down roofing provides the necessary waterproofing and durability that asphalt shingles cannot offer in these applications.

Potential Drawbacks and Considerations

The Challenges of Torch Down Roofing

While torch down roofing offers numerous benefits, there are some challenges to consider:

  • Need for Professional Installation: The installation process involves the use of an open flame, which can be dangerous if not handled correctly. A roofing professional is essential to ensure safety and achieve the best results.
  • Fire Hazards During Installation: The use of a roofing torch requires careful handling to prevent accidental fires. Safety protocols, such as having fire extinguishers on hand and wearing protective gear, must be strictly followed.

When Torch Down Roofing May Not Be the Best Option

Torch down roofing is not suitable for every situation. It may not be the best choice if:

  • The Roof Has a Steep Slope: Torch down roofing is designed for flat or low-slope roofs. If your roof has a steep slope, other roofing materials, such as asphalt shingles or metal roofing, may be more appropriate.
  • Budget Constraints: While torch down roofing is cost-effective in the long run, the initial installation cost may be higher compared to other options. If budget is a significant concern, alternative roofing materials may be considered.

Cost of Torch Down Roofing

Understanding the Investment

The cost of a torch down roofing system can vary depending on several factors, including the size of the roof, the type of membrane used, and the complexity of the installation. On average, you can expect to pay between $7,000 and $15,000 for a torch down roof on a typical residential property.

Cost Comparison with Other Roofing Types

When compared to other roofing materials, torch down roofing offers a balance of cost and performance:

  • EPDM Roofing: Typically less expensive to install but may require more frequent repairs and replacements.
  • TPO Roofing: Similar in cost to torch down roofing but may not offer the same level of durability in extreme weather conditions.
  • Asphalt Shingles: Less expensive initially but may not provide the same longevity or waterproofing capabilities.

Maintenance Tips for Torch Down Roofing

Keeping Your Torch Down Roof in Top Shape

Proper maintenance is key to maximizing the lifespan of a torch down roof. Here are some tips to keep your roof in optimal condition:

  • Routine Inspections: Schedule regular inspections to check for any signs of damage, such as cracks, blisters, or punctures. Early detection of issues can prevent more significant problems down the line.
  • Cleaning: Keep the roof surface clean and free of debris. Accumulated debris can trap moisture and lead to water infiltration.
  • Sealing: Periodically check the seams and edges of the roof to ensure they are properly sealed. Re-sealing may be necessary to maintain the roof’s waterproofing capabilities.

Longevity and Performance: What to Expect

With proper maintenance, a torch down roof can last 15 to 20 years or more. The key to longevity is regular inspections and prompt repairs when necessary. By addressing issues early, you can prevent more extensive damage and extend the life of your roof.

Energy Efficiency and Environmental Impact

Is Torch Down Roofing Energy Efficient?

Torch down roofing can contribute to energy savings, particularly in regions with hot summers. The granulated cap sheets reflect solar rays, helping to keep the interior of the building cooler. This reduces the need for air conditioning and can lead to lower energy bills over time. Additionally, the energy efficiency of torch down roofing can be further enhanced by choosing reflective cap sheets that are specifically designed to deflect more heat, making your building even more energy-efficient and environmentally friendly.

Environmental Considerations and Sustainability

Torch down roofing is not only energy-efficient but also has a relatively low environmental impact, especially when compared to other roofing options. Here are a few points to consider:

  • Longevity Reduces Waste: The long lifespan of torch down roofing means fewer replacements over time, which translates to less roofing material ending up in landfills.
