Torch-on roofing is a common choice for flat roofs in Toronto thanks to its durability and weather resistance. While it holds up well under heavy snow and fluctuating temperatures, even torch-on roofs can develop cracks, blisters, or leaks over time. Understanding the benefits of this roofing system and the costs associated with repair can help you plan ahead and avoid surprises.
What Is Torch-On Roofing?
Torch-on roofing is a type of modified bitumen system installed in layers and sealed using a propane torch. This creates a watertight membrane that’s ideal for low-slope and flat roof structures—especially common on Toronto homes, additions, and commercial buildings.
Torch-on roofs are designed to last 15–25 years, depending on installation quality and maintenance.
Common Problems and When Repairs Are Needed
Despite its strength, torch-on roofing can develop issues like seam separation, ponding water, or blistering due to age, improper installation, or prolonged exposure to UV rays.
If you notice signs of water intrusion, soft spots, or visible cracks in the membrane, it’s time to call in professionals. At Roof Repair Toronto, we offer full assessments and long-lasting repairs using the proper materials and techniques for torch-on systems.
How Much Do Repairs Cost?
The cost of torch-on roof repair varies depending on the size of the affected area and the type of damage. Minor repairs might range from a few hundred dollars, while major membrane replacements or re-welding can cost more. Acting early prevents damage from spreading and keeps costs down.
Why Inspections Are Essential
Since flat and low-slope roofs don’t always show visible damage, leaks can go undetected. A seasonal roof inspection is the best way to identify hidden issues early and maintain waterproofing performance.
Conclusion
Torch-on roofs are built for strength—but they still need occasional repairs to stay watertight. By understanding the signs of damage and investing in regular inspections, you can extend the life of your roof and avoid major expenses.
