Torch On Roofing Calgary: Pros, Cons & Expert Insights for Businesses

Torch On Roofing: Pros and Cons for Calgary Businesses

In the heart of Alberta, Calgary businesses face unique challenges when it comes to roofing. The city's dynamic climate, characterized by harsh winters, scorching summers, and the occasional hailstorm, demands roofing solutions that can withstand these diverse conditions. Among the various options available, torch on roofing has gained significant popularity in recent years. But is it the right choice for your Calgary business? Let's dive deep into the pros and cons of torch on roofing to help you make an informed decision.

Understanding Torch On Roofing

Before we weigh the advantages and disadvantages, it's crucial to understand what torch on roofing actually is. Torch on roofing, also known as torch down roofing or modified bitumen roofing, is a type of roofing system commonly used on flat or low-slope roofs. It consists of layers of modified bitumen membranes that are heated with a torch and then adhered to the roof surface.

The Installation Process

The installation of a torch on roof is a specialized process that requires skilled professionals. Here's a brief overview of how it's done:

1. Preparation: The existing roof surface is cleaned and prepared.
2. Base layer: A base sheet is mechanically fastened or adhered to the roof deck.
3. Torch application: The modified bitumen sheets are unrolled and heated with a propane torch.
4. Adhesion: As the underside of the sheet melts, it's pressed onto the roof surface, creating a watertight seal.
5. Multiple layers: This process is repeated for additional layers, typically including a cap sheet for UV protection.

Now that we have a basic understanding of torch on roofing, let's explore its pros and cons in the context of Calgary's business environment.

Pros of Torch On Roofing for Calgary Businesses

1. Exceptional Waterproofing

One of the primary advantages of torch on roofing is its superior waterproofing capabilities. The heat-welded seams create a seamless membrane that's highly resistant to water penetration. This is particularly beneficial in Calgary, where spring thaws and summer rainstorms can put roofs to the test.

2. Durability in Extreme Temperatures

Calgary's temperature swings can be dramatic, but torch on roofing stands up well to these fluctuations. The modified bitumen used in these systems is designed to remain flexible in cold temperatures and stable in heat, reducing the risk of cracking or blistering.

3. Resistance to UV Radiation

The cap sheet used in torch on roofing systems often includes granules or a reflective coating that provides excellent UV protection. This helps maintain the roof's integrity and can contribute to better energy efficiency for your business.

4. Long Lifespan

When properly installed and maintained, torch on roofing can last 20 to 30 years. This longevity makes it an attractive option for Calgary businesses looking for a durable, long-term roofing solution.

5. Ease of Repair

If damage does occur, torch on roofing is relatively easy to repair. Patches can be applied using the same torch-down method, seamlessly integrating with the existing roof.

6. Fire Resistance

The materials used in torch on roofing are inherently fire-resistant, which can be a significant advantage for businesses concerned about fire safety.

7. Cost-Effective Over Time

While the initial installation cost may be higher than some alternatives, the durability and longevity of torch on roofing can make it a cost-effective choice in the long run.

Cons of Torch On Roofing for Calgary Businesses

1. Installation Risks

The use of open flames during installation poses fire risks. This requires highly skilled professionals and strict safety protocols, which can increase installation costs.

2. Weather-Dependent Installation

The installation of torch on roofing is weather-sensitive. Calgary's unpredictable weather can lead to project delays if conditions aren't suitable for torch application.

3. Potential for Improper Installation

The quality of a torch on roof is highly dependent on proper installation. Inexperienced or careless installers can leave vulnerabilities that compromise the roof's integrity.

4. Higher Initial Costs

Compared to some other flat roofing options, torch on roofing typically has a higher upfront cost due to the materials and specialized labor required.

5. Environmental Concerns

The process of heating bitumen releases volatile organic compounds (VOCs), which can be a concern for environmentally conscious businesses.

6. Limited DIY Repairs

While professional repairs are straightforward, DIY repairs are not recommended due to the specialized equipment and skills required.

7. Weight Considerations

Torch on roofing systems can be heavier than some alternatives, which may be a concern for older buildings or those with structural limitations.

Considerations for Calgary Businesses

When deciding whether torch on roofing is right for your Calgary business, consider the following factors:

Building Structure

Is your building suitable for the weight of a torch on roofing system? Have a structural assessment done if you're unsure.

Budget

While torch on roofing can be cost-effective long-term, ensure you have the budget for the initial investment.

Business Operations

Consider how the installation process might impact your business operations. Can you accommodate potential delays due to weather?

Environmental Goals

If your business has strong environmental commitments, weigh the environmental impact of torch on roofing against its benefits.

Long-Term Plans

Are you planning to stay in your current location long-term? The durability of torch on roofing makes it ideal for businesses with long-term stability.

Local Regulations

Ensure that torch on roofing meets all local building codes and regulations in Calgary.

Maintenance Tips for Torch On Roofs in Calgary

To maximize the lifespan and performance of a torch on roof in Calgary's climate, consider these maintenance tips:

1. Regular Inspections: Schedule professional inspections at least twice a year, especially after severe weather events.
2. Keep It Clean: Remove debris regularly to prevent water pooling and drainage issues.
3. Address Issues Promptly: Don't delay repairs if you notice any damage or signs of wear.
4. Snow Removal: After heavy snowfalls, consider professional snow removal to prevent excessive weight on the roof.
5. Check Seals: Pay special attention to areas around vents, chimneys, and other roof penetrations during inspections.
6. Recoating: Consider applying a reflective coating every few years to enhance UV protection and energy efficiency.

By following these maintenance practices, Calgary businesses can ensure their torch on roofs perform optimally for years to come.

Q&A: Common Questions About Torch On Roofing in Calgary

How does torch on roofing perform in Calgary's winter conditions?

Torch on roofing performs exceptionally well in Calgary's harsh winters. The modified bitumen used in these systems is designed to remain flexible even in extreme cold, reducing the risk of cracking or brittleness. The seamless nature of the installation also helps prevent water infiltration from ice dams or snow melt. However, it's important to manage snow load on flat roofs to prevent excessive weight stress. Many Calgary businesses find that torch on roofing provides reliable protection throughout the winter months, but regular inspections and snow removal when necessary are still recommended.

What is the typical lifespan of a torch on roof in Calgary's climate?

In Calgary's climate, a well-installed and properly maintained torch on roof can last between 20 to 30 years. This longevity is due to the durability of the materials and their resistance to UV radiation, temperature fluctuations, and moisture. However, the actual lifespan can vary depending on factors such as the quality of installation, the specific products used, exposure to extreme weather events, and the level of maintenance provided. Regular inspections and timely repairs can help maximize the lifespan of your torch on roof.

How does the cost of torch on roofing compare to other commercial roofing options in Calgary?

While the initial cost of torch on roofing is generally higher than some other commercial roofing options in Calgary, it often proves cost-effective in the long run. Here's a rough comparison:

• Torch on roofing: Higher upfront cost, but longer lifespan (20-30 years)
• Single-ply membranes (e.g., TPO, EPDM): Lower initial cost, shorter lifespan (15-20 years)
• Built-up roofing: Comparable cost to torch on, similar lifespan
• Metal roofing: Higher initial cost, longest lifespan (40+ years)

When considering costs, factor in not just the initial installation, but also long-term maintenance, energy efficiency, and potential repair needs. Many Calgary businesses find that the durability and performance of torch on roofing justify the higher upfront investment.

Are there any specific building code requirements for torch on roofing in Calgary?

Yes, there are specific building code requirements for torch on roofing in Calgary. These fall under the Alberta Building Code and local Calgary bylaws. Key points include:

• Fire safety measures during installation
• Minimum slope requirements for drainage
• Insulation and vapor barrier specifications
• Wind uplift resistance standards

Additionally, the City of Calgary often requires building permits for new roofing installations or significant repairs. It's crucial to work with a licensed roofing contractor familiar with local codes and permit processes. They can ensure your torch on roofing project meets all necessary requirements and passes inspections.

How does torch on roofing impact a building's energy efficiency in Calgary?

Torch on roofing can positively impact a building's energy efficiency in Calgary in several ways:

1. Insulation: The multiple layers provide good insulation, helping maintain indoor temperatures.
2. Reflectivity: Many torch on systems include a reflective cap sheet, which can reduce heat absorption in summer.
3. Seamless installation: The continuous membrane minimizes air leakage, improving overall building envelope performance.

In Calgary's climate, where both heating and cooling demands are significant, these features can contribute to energy savings. Some businesses report noticeable reductions in their heating and cooling costs after installing a torch on roof. However, the exact impact on energy efficiency will depend on the specific products used and the overall building design.

What are the environmental considerations of torch on roofing for Calgary businesses?

Torch on roofing has both positive and negative environmental aspects that Calgary businesses should consider:

Pros:

• Durability means less frequent replacement, reducing waste
• Can be installed over existing roofing in some cases, minimizing landfill waste
• Reflective coatings can reduce urban heat island effect

Cons:

• Installation process releases VOCs (volatile organic compounds)
• Made from petroleum-based products
• Not easily recyclable at end of life

Some manufacturers are developing more eco-friendly versions of modified bitumen membranes. For businesses prioritizing sustainability, it's worth exploring these options or considering alternative green roofing systems. However, the long lifespan and energy-efficient properties of torch on roofing can offset some of its environmental drawbacks.

How does the warranty coverage for torch on roofing typically work in Calgary?

Warranty coverage for torch on roofing in Calgary typically includes:

1. Manufacturer's warranty: Covers defects in the roofing materials, usually for 10-20 years.
2. Workmanship warranty: Provided by the roofing contractor, covering installation issues, typically for 2-5 years.

Some key points to understand:

• Warranties often require regular maintenance and inspections to remain valid.
• Coverage may be prorated, meaning the reimbursement value decreases over time.
• Extreme weather events or "acts of God" are usually not covered.
• Some manufacturers offer extended warranties when their certified contractors perform the installation.

It's crucial to read and understand the warranty terms before installation. Ask your roofing contractor to explain the coverage in detail, including any maintenance requirements to keep the warranty valid.

How does torch on roofing handle the potential for hail damage in Calgary?

Torch on roofing generally performs well against hail damage in Calgary, which is important given the city's propensity for severe hailstorms. Here's how it stands up:

• Impact resistance: The multiple layers and robust materials provide good protection against hail impacts.
• Flexibility: The modified bitumen can absorb some impact without cracking or puncturing.
• Granulated cap sheet: The top layer often includes embedded granules that add an extra layer of protection.

While torch on roofing is resistant to hail damage, it's not impervious. Extremely large hailstones can still cause damage. After significant hailstorms, it's wise to have your roof inspected for any potential issues. Many insurance policies in Calgary cover hail damage, but it's important to document any damage promptly.

Some manufacturers offer enhanced hail-resistant versions of their torch on roofing products, which might be worth considering for extra protection in Calgary's climate.
