Having a roof leak detected is smart and fast with Ultrices leak detection, especially if that damp spot keeps coming back. We find the source in flat and tiled roofs, including EPDM and bitumen, without demolition.
We inspect dormer windows, chimneys, gutters, and skylights, and test using thermography, a smoke test, endoscopy, and moisture measurement. This is how you prevent damage to wood, insulation, and ceilings.
You receive a clear report for the insurer, repair advice, and emergency repairs if necessary. Read our Google reviews on detecting roof leaks and choose certainty. Google reviews five out of five.

What is having a roof leak detected?
Having a roof leak detected means determining, precisely and without damage, where water is entering your roof and why. At Ultrices Leak Detection, we combine structural knowledge with geometry to quickly provide clarity regarding flat roofs with bitumen APP or SBS, EPDM, or PVC, and pitched roofs with roof tiles, slates, or zinc. We examine details such as lead flashing, valley gutters, chimneys, roof penetrations, rainwater drainage connections, skylights, and Velux roof windows. Our technicians are VCA VOL and NEN 3140 certified, work nationwide, and provide an expert report that you can take directly to your insurer. Thanks to professional detection equipment and a process based on physical principles such as capillary action and vapor pressure, we measure precisely and avoid guesswork.
How does professional roof leak detection work
- Intake and triageWe discuss symptoms, location in the house, recent precipitation, and maintenance history, and use KNMI precipitation data for context where relevant.
- Visual inspectionWe check the roofing, seams, details around the chimney, dormer, roof edge, and penetrations, and identify aging, blisters, or cracks.
- Non-destructive measurementsUsing thermography, moisture measurements, and endoscopy, we locate thermal bridges, water pathways, and hidden cavities.
- Targeted testWe perform a controlled water test, smoke test, or tracer gas test to confirm the cause without any demolition or breaking.
- Analysis and reportWe document findings with photos, measurements, and a clear cause-and-effect analysis, including repair advice and priorities.
- Insurance alignmentYou will receive a complete expert report within three days that aligns with policy conditions, so that you can file a claim smoothly.
Leak detection process request
Common causes by roof type
- Flat roof with bitumen or EPDM: open overlaps, poorly welded seams, crazing, cracks at roof edges, and leaking rainwater drains are common, especially after heat and frost.
- Tiled roof: cracked tiles, aged ridge tiles, clogged or leaking valley gutters, and porous or broken lead flashing around the chimney and dormer cause infiltration.
- Zinc or copperCorrosion, solder joints with hairline cracks, and expansion stresses cause drip leaks that appear as ceiling damage indoors.
- Penetrations and skylights: Outdated rubber seals, incorrect upstands, and faulty connection details on skylights and Velux windows lead to capillary leakage during driving rain.
Technology and methods for leak detection on roofs
- IR ThermographyUsing a FLIR thermal imaging camera, we visualize temperature differences, making wet insulation, thermal bridges, and leaks visible, even on green roofs.
- Moisture measurement and dielectric scanningWith Tramex measuring equipment, we determine the moisture content in roofing and underlays without opening them.
- Tracer gas or smoke test: using a Trotec smoke generator or an inert gas mixture, we locate micro-leaks at seams, penetrations, and upstands with high precision.
- Dye and endoscopyFluorescein and camera inspection follow the flow path behind facades, cavity walls, and roof insulation so that cause and effect become irrefutable.

From finding to repair and insurance
You receive a clear plan with priorities for each detail, such as replacing lead flashing on a chimney or refinishing PVC or EPDM upstands. The expert report includes photo locations, floor plan markings, measurement results, cause-and-effect chain analysis, urgency, and repair advice, including prevention tips such as the maintenance frequency of gutters and roof edges. Our documentation meets the requirements of insurers and claims experts to ensure your case is processed quickly. Because we work without demolition or breaking and have a ninety-nine percent success rate, the inspection is completely risk-free with a no-cure no-pay policy and a guarantee of coverage. We assist both private and commercial property owners in the Randstad, Brabant, Gelderland, Limburg, and the North, among other regions.
Recognize roof leaks and make smart choices
- Signals within: circles on the ceiling, mold around the soffit or dormer, and peeling plaster indicate a leak that often originates meters away from the visible spot.
- Signals outside: Blisters in bitumen, open seams, moss growth at the valley gutter, or crooked tiles pose a risk of water ingress with wind from the west to northwest.
- Difference between rain and condensationMeasuring vapor pressure and dew point prevents confusion between an actual roof leak and condensation damage caused by insufficient ventilation of the attic.
- Timing and weatherAfter heavy downpours or prolonged drizzle, we use water tests and data to simulate and reproduce leakage behavior for hard evidence.

Frequently asked questions
How do you have a roof leak detected quickly and without demolition work?
You call us and we respond immediately. We are available nationwide, often on-site within one hour, and work day and night with an emergency service. With over fifteen years of experience, VCA VOL and NEN 3140 certification, and professional detection equipment, we find the cause without any demolition or breaking.
We combine thermal imaging thermography, smoke tests on flat roofs with bitumen or EPDM, dye tracers, endoscopy, moisture measurements, ultrasound, and tracer gas. For example, we recently identified a leaking sealant joint on a dormer that only occurred during westerly winds. Within forty minutes, the cause was determined, and targeted repairs could be carried out.
How much does it cost to have a roof leak detected, and does your insurance cover this?
The investment depends on the roof type (flat or tiled), accessibility, height, and the complexity of details such as penetrations, chimneys, or valley gutters. You will receive a free quote within twenty-four hours. Thanks to our no-cure-no-pay approach and a ninety-nine percent success rate, you choose certainty without financial risk.
Many buildings insurance policies cover leak detection and consequential damage, depending on your policy and deductible. We deliver a complete expert report with photos, measurement data, and repair advice within three days and liaise smoothly with insurers.

Which method works best for a flat roof or a tiled roof, and when do you choose a smoke test or thermography?
On flat roofs with bitumen or EPDM, a smoke test is ideal for finding cracks at overlaps, eaves, and roof edges. We combine this with thermography for thermal frames, dye tracers around penetrations, and endoscopy beneath the top layer. With a sufficient temperature difference, the thermal imaging camera captures hidden water trails with razor-sharp precision.
On tiled roofs, we focus on vulnerable points such as ridge tiles, zinc valley gutters, lead flashing around chimneys, dormer details, skylights, and rainwater drains. Using section-specific spray testing and camera inspection, we systematically rule out causes. If water primarily enters during crosswinds, rain may be penetrating through the facade. Read how we demonstrate this in investigation into rain penetration through the facade.
How quickly do you arrive on site and what do you receive after the investigation?
We are available twenty-four hours a day, seven days a week, and can often start within one hour, nationwide. We work with certified professionals for both business and private clients, with five out of five stars in customer reviews. No solution means no payment, and you are one hundred percent risk-free.
After the leak detection, you will receive a clear report with photos, measurement results, the root cause, and practical repair advice including an estimate.
