Hot Torch Roofing Insurance: What You Need – and What Could Cost You If You Don’t Have It

If you’re doing hot torch roofing – whether it’s modified bitumen, torch-on, or torch-down applications – you already know the risks. Open flame. Extreme heat. Combustible materials. One mistake and you’re looking at a fire claim, a lawsuit, or worse.

What you might not know is exactly what your roofing insurance policy needs to include to actually protect you. That’s what this guide covers.

What Liability Risks Do Hot Torch Roofers Face?

Hot torch roofing involves open flame reaching over 2,000°F (1,093°C). That’s not a metaphor for risk, that’s a literal fire hazard on every job site.

And fire is just the start. Even the most experienced crews face a range of liability exposures on every project, including:

• Third-party property damage claims on customer and neighbouring properties
• Third-party bodily injury claims if customers or passersby are hurt because of your operations
• Injuries to workers, including heat-related illnesses and burns
• Environmental and pollution claims arising from the improper handling of materials, such as asphalt, that pollute soil, water, or the air
• Theft of or vandalism to your tools and equipment
• Regulatory compliance fines or legal actions if you fail to comply with local building codes, safety regulations, and industry standards

What Does a Hot Torch Roofing Insurance Policy Include?

A comprehensive hot torch roofing insurance policy typically includes the following types of coverage:

• Commercial General Liability (CGL) Insurance: CGL, or general liability insurance, covers third-party bodily injury and third-party property damage claims arising from your roofing operations.
  
  It’s designed to pay for injuries to customers or passersby on job sites, damages to properties caused by your work, and unexpected accidents. Without it, a single property damage or injury claim could cost you tens of thousands of dollars out of pocket, and potentially your business.

• Tools and Equipment Insurance: Tools and equipment insurance covers repairing or replacing your roofing business’s transportable tools and equipment if stolen, vandalized, or damaged by fire, water, and natural disasters.
  
  Propane torches, infrared thermometers, and other specialized roofing equipment aren’t cheap to replace. This coverage means a theft or fire on-site doesn’t stall your next job.

• Pollution Liability Insurance: Pollution liability insurance pays for sudden or gradual third-party bodily injuries, third-party property damages, and environmental damages caused by the materials and chemicals used for hot torch roofing applications.
  
  It is designed to pay for clean-up costs, emergency response expenses, and civil fines. Asphalt and bitumen runoff can trigger environmental claims even when you’ve done everything right, and cleanup costs add up fast.

Other coverages hot torch roofers often add:

• Professional Liability Insurance: Professional liability insurance, or errors and omissions (E&O) insurance, covers roofers who provide consulting and design services against claims of professional negligence, mistakes, inadequate repair jobs, and faulty installations. If a client claims your design recommendation or repair job caused damage, this covers your legal fees and any settlement – even if the claim turns out to be unfounded.

• Commercial Auto Insurance: Commercial auto insurance covers your roofing business’s vehicles and trailers against liabilities such as auto accidents, property damage, or bodily injuries to others involving your company-owned or -leased vehicles.
  
  Your personal auto policy won’t cover accidents in a company vehicle. If your crew drives to job sites in a business-owned truck or van, this isn’t optional.

5 Tips for Minimizing Hot Torch Roofing Accidents and Damages

Good insurance is your financial backstop, but the goal is always to avoid a claim in the first place.

Here are five safety tips recommended by the Infrastructure Health and Safety Association:

1. Wear Personal Protective Equipment (PPE)

Roofers should always wear proper PPE, including Canadian Safety Association-approved hard hats, gloves, eye protection, and boots. Workers should also wear fire-resistant clothing while on site.

2. Only Permit Trained Roofers to Do Hot Torch Roofing

Ensure that workers have been adequately trained to install torch-applied modified bitumen roofing systems, including appropriate training in storing, handling, and using roofing propane. All workers who aren’t torch operators should stay at least 2 metres away from the flame.

3. Inspect the Roof Surface

Check the roof surface for combustible material and debris before you start. Remove or isolate anything flammable, and be extra cautious when torching near pipes, HVAC infrastructure, and air vents. Never torch near gas or electrical lines.

4. Inspect Torches Before Use

Never use propane equipment that leaks or isn’t in excellent condition. Torch units should be set to their support leg position with the torch head pointing upwards. Never place them on a roof’s edge or leave them unattended. Cease torching operations at least three hours before the end of the work day.

5. Appoint a Designated Fire Spotter

One crew member should be responsible for watching for fires at all times. They should keep dry chemical fire extinguishers within 6 metres of each torch operator, make sure every roofer knows the escape route, and inspect the roof for hot spots with an infrared thermometer once work is complete. Don’t forget to check the building interior, too. Torching applications can smoulder and ignite long after the crew has packed up.

Note: Welders are typically required by insurance providers to have an assigned fire spotter present at every worksite.

Even when your crew follows every one of these protocols, accidents still happen. That’s not a knock on your professionalism, it’s just the reality of the trade. Insurance is what separates a bad day from a business-ending one.

Is pollution liability insurance required for hot torch roofers?

It’s not always legally required, but it’s strongly recommended. Asphalt and bitumen materials can cause environmental damage if improperly handled, and cleanup costs can be significant.
