What Is Roof Thermal Imaging Inspections?
A roof thermal imaging inspection is a non-destructive infrared survey that scans a roof surface for temperature anomalies marking moisture-contaminated insulation beneath an intact membrane. It applies ASTM C1153, the standard practice for locating wet insulation in roofing systems using infrared imaging, then verifies each anomaly by core cut.
What Roof Thermal Imaging Inspections Do We Provide?

Newark Quality Roofing performs roof thermal imaging inspections across Essex County under ASTM C1153, the standard practice for locating wet insulation in roofing systems using infrared imaging — for commercial and residential properties. A thermal imaging inspection scans the roof surface for temperature anomalies that mark moisture-contaminated insulation beneath an intact membrane, non-destructively, per the NRCA and IIBEC.
Wet insulation holds a higher heat capacity and cools more slowly than dry insulation, so after sunset dry insulation releases heat fast while moisture-contaminated areas stay warmer and read as warm anomalies on a thermal scan, per Fluke and IIBEC. ASTM C1153 requires every suspected wet area be verified by core cut, probe, or calibrated moisture meter, because an infrared camera detects temperature patterns rather than water directly and the wet-insulation footprint sits displaced from the leak entry point, per ASTM C1153 and Fluke. A Newark Quality Roofing thermal imaging inspection maps the moisture footprint before a repair or replacement scope sets the affected area.
- ASTM C1153 wet-insulation survey — ASTM C1153 wet-insulation survey scans a low-slope roof for warm anomalies that mark moisture-contaminated insulation, under ASTM C1153, the most commonly used standard for infrared roof moisture inspection, per ASTM and the NRCA.
- Non-destructive infrared scan — Non-destructive infrared scan evaluates surface thermal patterns without opening the roof assembly, surveying a large low-slope roof faster than a point-by-point moisture-meter survey, per the NRCA and IIBEC.
- Core-cut verification — Core-cut verification confirms a thermal anomaly at a core cut, probe, or calibrated moisture meter, because ASTM C1153 requires verification of every suspected wet area and an infrared camera detects temperature, not water, per ASTM C1153 and Fluke.
- Moisture mapping for repair and replacement scoping — Moisture mapping for repair and replacement scoping delineates the wet-insulation footprint on the roof plan, the data that sizes a selective commercial repair against a full membrane replacement, per IIBEC and the NRCA.
- Pre-purchase and insurance condition survey — Pre-purchase and insurance condition survey documents concealed wet insulation for a property transaction or claim, recording subsurface moisture an intact membrane hides from a visual inspection, per IIBEC and Fluke.
How Do You Know If You Need Roof Thermal Imaging Inspections?




- Intermittent leaks that a visual inspection cannot locate mark a moisture footprint sitting displaced from the breach, because an infrared survey locates wet insulation rather than the leak entry point itself, per Fluke and IIBEC.
- An intact membrane over a roof that still admits water indicates subsurface moisture, the concealed wet insulation a non-destructive infrared scan reads as a warm anomaly after sunset, per the NRCA and IIBEC.
- A planned repair or replacement on a low-slope commercial roof calls for a wet-insulation survey, because the moisture footprint sizes a selective repair against a full membrane replacement, per ASTM C1153 and IIBEC.
- Higher heating or cooling cost on a building with no visible roof defect points to compromised insulation, a thermal pattern an infrared scan distinguishes from normal roof temperature variation, per Fluke and IIBEC.
- Recent storm activity, HVAC work, or rooftop traffic over a membrane warrants an infrared scan to find concealed moisture introduced beneath the surface, verified at a core cut per ASTM C1153, per ASTM C1153 and Fluke.
- A property acquisition, insurance renewal, or refinancing on a commercial building prompts a documented condition survey that records both visible and concealed conditions, per IIBEC and the NRCA.

How Do Our Roofing Contractors Perform Roof Thermal Imaging Inspections?

Newark Quality Roofing schedules a thermal imaging scan for the ASTM C1153 optimal conditions and scans after sunset on a clear day, the window that produces the sharpest wet-insulation contrast. The ASTM C1153 optimal conditions call for no appreciable precipitation in roughly the prior 48 hours, a dry surface clear of standing water, snow, and debris, wind under about 15 mph, and an adequate temperature differential of roughly 18°F, on a clear sunny day followed by a clear night, per ASTM C1153 via IIBEC and Fluke. A Newark Quality Roofing technician scans after sunset, because wet insulation cools more slowly than dry insulation and the warm anomaly reaches its sharpest contrast as the dry roof releases heat, per ASTM C1153 via IIBEC, the NRCA, and Fluke. Winter narrows the contrast to roughly 5°F against roughly 20°F in summer, so a Newark Quality Roofing technician confirms an adequate differential before the scan, per IIBEC and Fluke.
Newark Quality Roofing scans the roof surface with a calibrated infrared imager, flags every warm anomaly, and verifies each suspected wet area by core cut, probe, or calibrated moisture meter as ASTM C1153 requires. A modern infrared imager resolves a temperature difference of roughly 0.2°F and reads wet-area anomalies ranging from roughly 0.5°F to 30°F, per IIBEC and Fluke, and a Newark Quality Roofing technician separates a moisture anomaly from a normal thermal pattern caused by a structural member, rooftop equipment, or an interior heat source. Verification at a core cut, probe, or calibrated moisture meter confirms the moisture, because an infrared camera detects temperature patterns rather than water directly, per ASTM C1153 and Fluke.
Newark Quality Roofing maps the verified wet-insulation footprint to the roof plan and reports the moisture extent that sizes a repair or replacement scope. A wet-insulation map delineates the moisture footprint across a large low-slope roof faster than a point-by-point moisture-meter survey, per IIBEC and the NRCA, and the mapped extent separates a selective repair of the wet area from a full membrane replacement. ASTM D7954 nuclear moisture surveys and capacitance moisture meters confirm a thermal finding where a core cut alone leaves the extent uncertain, per ASTM and trade guidance.
What Commercial Roof Thermal Imaging Inspections Do We Provide?
Newark Quality Roofing performs thermal imaging inspections on commercial low-slope roofs across Essex County, scanning EPDM rubber, TPO, modified-bitumen, and built-up membranes for wet insulation under ASTM C1153. EPDM lasts 15 to 25 years, TPO 7 to 20 years, modified bitumen 20 years, and built-up roofing 30 years, per the InterNACHI life-expectancy chart, and a wet-insulation survey maps the moisture footprint before a repair or replacement sets the affected area.
A Newark Quality Roofing commercial scan maps the verified wet-insulation footprint, the data that separates a selective repair of the wet area from a full membrane replacement, per IIBEC and the NRCA. On a commercial building, repairing more than 25% of the total roof area in a 12-month period requires a permit under N.J.A.C. 5:23-2.7, per the NJ Uniform Construction Code, so a Newark Quality Roofing thermal imaging report sizes the moisture extent before a repair scope sets the permit path. Ponding water remaining on a low-slope roof more than 48 hours counts as a defect, and a flat roof needs at least ¼ inch per foot of slope to drain, per the NRCA and ARMA.

What Residential Roof Thermal Imaging Inspections Do We Provide?
Newark Quality Roofing performs thermal imaging inspections on detached one- and two-family homes across Essex County, locating concealed moisture and insulation deficiencies an intact roof surface hides from a visual inspection. A repair or replacement of the roof covering on a detached one- and two-family dwelling counts as ordinary maintenance under N.J.A.C. 5:23-2.7 and requires no construction permit, so a Newark Quality Roofing thermal imaging report documents condition rather than triggering a permit, per the NJ Uniform Construction Code.
A Newark Quality Roofing residential thermal scan runs after sunset under the ASTM C1153 optimal conditions, because wet insulation stays warmer than dry insulation as the roof cools, per ASTM C1153 via IIBEC and Fluke, and every warm anomaly verifies at a core cut, probe, or calibrated moisture meter. A pre-purchase thermal scan records subsurface moisture and insulation gaps for a real-estate transaction, the concealed conditions a standard home inspection misses, per IIBEC and the NRCA.

What Are the Steps in Our Roof Thermal Imaging Inspections Process?

- Pre-Scan Planning and Condition Check
A Newark Quality Roofing technician confirms the ASTM C1153 optimal conditions before the scan: no appreciable precipitation in roughly the prior 48 hours, a dry surface, wind under about 15 mph, and an adequate temperature differential, per ASTM C1153 via IIBEC, the NRCA, and Fluke.
- Solar Loading and After-Sunset Timing
A Newark Quality Roofing technician scans after sunset on a clear day followed by a clear night, because wet insulation cools more slowly than dry insulation and the warm anomaly reaches its sharpest contrast as the dry roof releases heat, per ASTM C1153 via IIBEC and Fluke.
- Calibrated Infrared Scan
A Newark Quality Roofing technician scans the roof surface with a calibrated infrared imager that resolves a temperature difference of roughly 0.2°F, recording every warm anomaly with its location on the roof plan, per IIBEC and Fluke.
- Anomaly Interpretation
A Newark Quality Roofing technician separates a moisture anomaly from a normal thermal pattern caused by a structural member, rooftop equipment, or an interior heat source, because an infrared camera detects temperature patterns rather than water directly, per Fluke, IIBEC, and the NRCA.
- Core-Cut Verification
A Newark Quality Roofing technician verifies each suspected wet area by core cut, probe, or calibrated moisture meter, because ASTM C1153 requires verification of every thermal anomaly before a finding records as wet insulation, per ASTM C1153 and Fluke.
- Wet-Insulation Map and Report
A Newark Quality Roofing technician maps the verified wet-insulation footprint to the roof plan and reports the moisture extent that sizes a repair or replacement scope, per IIBEC and the NRCA.
