Flat roof leaks can be difficult to trace—especially when the water doesn’t drip directly beneath the damage. In Toronto, where freeze-thaw cycles and heavy rainfall are common, water often travels beneath the roofing membrane before showing up inside the property. That’s why infrared scanning has become one of the most reliable and non-invasive ways to detect hidden leaks and trapped moisture in flat roofs.
Infrared, or thermal, scanning involves the use of a specialized camera that detects temperature differences across your flat roof. When moisture becomes trapped beneath the surface—whether from a seam failure, a puncture, or flashing damage—it alters the thermal pattern of the roof. Moisture-retaining areas tend to hold heat differently than dry areas, and this contrast becomes visible through the thermal camera, allowing technicians to “see” water even when it’s not visible to the naked eye.
For Toronto property owners, this technology is a game-changer. Many flat roofs in the city are covered in multiple layers of material, and leaks may not present any exterior signs. You might only notice the issue once water stains appear on ceilings or mold develops inside. By then, the damage has likely spread. Infrared scanning allows you to catch these problems much earlier, before the structural elements are compromised or insulation becomes saturated.
What makes this solution even more valuable is that it’s non-invasive. There’s no need to cut into the roof or tear away sections to look for moisture. Infrared scans are completed from the surface, making them fast, accurate, and safe for the roofing system. This method is ideal for both residential and commercial properties and is particularly effective when used in seasonal maintenance—especially in the spring after snow has melted or in the fall before winter sets in.
Another benefit is targeted repair. Instead of replacing large sections of the roof or applying patches based on guesswork, contractors can focus directly on the affected area. This leads to cost savings, faster repairs, and less disruption to tenants or operations.
Infrared inspections can also be part of your roof’s long-term maintenance plan. Regular scanning helps track aging, identify early signs of membrane deterioration, and monitor how well previous repairs are holding up. It’s also a valuable tool during real estate transactions or insurance assessments when accurate roof condition data is essential.
