Thermal-imaging Leak Detectors
Thermal-imaging Leak Detectors | Roof Repair | Roofing
When rainwater sneaks beneath shingles or membrane, the damage can spread far beyond the visible stain on your ceiling. HEP’s state-of-the-art thermal-imaging leak detectors pinpoint trapped moisture in minutes, revealing the exact path of infiltration without tearing up a single tile. By seeing temperature variations others miss, our specialists diagnose the problem on the spot, giving you clear images and a straightforward plan for roof repair that targets the source, not just the symptoms.
Because the scan is completely non-destructive, you avoid guesswork, unnecessary disruption and surprise costs. Whether you’re a homeowner protecting priceless heirlooms or a facility manager safeguarding inventory, HEP delivers precision, speed and peace of mind. Book your thermal survey today and discover how effortless, accurate and cost-effective roof repair can be with the right technology in trusted hands.
FAQs
How does thermal imaging identify roof leaks?
Thermal-imaging cameras measure infrared radiation (heat) emitted from the roof surface. Wet insulation or trapped moisture retains heat longer than dry areas, so on the camera’s screen those zones appear as hotter or colder "anomalies." By scanning the entire roof, our technicians can map these temperature differences, pinpointing where water has infiltrated without having to remove any materials.
What kinds of roofs can be inspected with thermal imaging?
Infrared surveys are effective on most low-slope commercial roofing systems—built-up (BUR), modified bitumen, single-ply membranes (EPDM, TPO, PVC), and spray-foam roofs—as well as many steep-slope residential roofs made of asphalt shingles, metal panels, clay tiles, or slate. The key requirement is that the roof has some form of insulation or decking underneath that holds moisture and thus shows a temperature contrast.
Is thermal-imaging leak detection safe for my roof and for occupants inside?
Yes. The process is completely non-destructive and contact-free. Our certified thermographers walk the roof with a lightweight camera or pilot a small drone; no cutting, drilling, or heavy equipment is involved. Infrared radiation is simply heat energy we all emit, so there is no harmful exposure to residents or workers below.
When is the best time to schedule a thermal roof survey?
For the strongest thermal contrast, we typically perform inspections shortly after sunset when the roof is releasing heat absorbed during the day, or just before sunrise following a clear night. Seasonal temperature swings can also help—spring and fall usually provide ideal conditions. We monitor local weather to choose a dry, wind-free window to ensure accurate readings.
How accurate is thermal imaging compared with traditional leak-detection methods?
Infrared inspection routinely locates 90-95 % of moisture intrusions that would otherwise require test cuts or water-hose simulations. It can reveal hidden wet areas long before stains appear indoors, allowing targeted repairs instead of full-scale tear-offs. While no single method is flawless, combining thermal data with on-site core sampling or moisture meters gives us near-certain confirmation.
What happens after you find a leak using thermal imaging?
You receive a detailed report that includes infrared photos, marked drawings of affected areas, and repair recommendations prioritized by severity. Because we are also a licensed roofing contractor, we can move immediately from diagnosis to corrective action—patching membrane breaches, replacing saturated insulation, sealing flashings, or planning partial reroofs—saving you valuable time and money.
