Albuquerque's low annual rainfall creates ideal conditions for infrared moisture scanning — high solar loading, low ambient humidity, and strong thermal contrast between wet and dry insulation. We use IR scanning to validate recover-versus-replace decisions and document moisture boundaries before you open the roof.
Saturated roof insulation is invisible from the surface. A TPO membrane that looks serviceable from a roof walk may be sitting on polyiso insulation that has absorbed moisture from a previous monsoon season's seam failure and never had the opportunity to dry out. With only nine inches of annual rainfall, Albuquerque buildings go long stretches without roof wetting — which means wet insulation does not wick dry the way it might in a humid climate. Moisture that enters during a monsoon event can remain in the insulation assembly for months or years before it is discovered.
Infrared scanning works by detecting the thermal differential between wet insulation — which retains heat longer than dry insulation after solar loading during the day — and the dry surrounding field. At 5,300 feet of elevation with more than 300 sunny days per year, Albuquerque provides some of the strongest solar loading of any commercial roofing market in the country. That loading amplifies the thermal contrast that infrared cameras detect, making the high desert one of the more favorable environments for accurate IR moisture scanning when conditions are right.
We use FLIR thermal imaging cameras on Albuquerque commercial roofs in the evening hours — typically 45 to 90 minutes after sunset during months with adequate solar loading — to map wet zones against the cooling dry field. The result is a moisture boundary map that guides targeted core sampling, which confirms what the thermal imaging detected and provides the basis for a recover-versus-replace recommendation grounded in actual moisture data rather than visual estimate.
When Infrared Scanning Is Appropriate
Pre-recover decision: Before committing capital to a recover versus full replacement, an infrared scan tells you how much of the existing insulation is dry and viable to recover over. If less than 25 percent of the roof reads as wet insulation, a recover with targeted tear-out of the wet zones is typically the sound capital decision. If more than 25 percent is wet, replacement is the honest scope — recovering over wet insulation in Albuquerque's low-humidity climate still traps moisture against the deck and voids the new system's warranty.
Post-monsoon damage documentation: After a significant monsoon event or a roof leak that has been temporarily repaired, infrared scanning identifies the extent of moisture migration that may not be visible as a surface stain or ceiling event. Monsoon convective cells deliver high rainfall intensity in short windows — moisture can enter through a single seam failure and spread laterally through the insulation before the interior evidence appears. IR scanning defines the boundary of that spread without opening the roof across the full suspect area.
Pre-sale or pre-refinance documentation: Buyers and lenders increasingly request infrared moisture scan reports as part of commercial roof due diligence. We produce dated, signed scan reports with thermal images and a written moisture boundary description for this purpose. Albuquerque's active medical, industrial, and government-contractor commercial market generates regular requests for this type of pre-transaction documentation.
Warranty investigation: When a building owner believes a roof is leaking but the contractor or manufacturer disputes the source, an independent infrared scan produces an objective moisture location record. We have conducted these third-party scans on buildings throughout the Albuquerque metro — Downtown, Uptown, and the I-25 medical corridor.
How We Conduct the Scan
Timing is the most critical variable. The scan must be conducted after adequate solar loading during the day and after the surface has begun to cool — the wet insulation retains heat while the surrounding dry membrane cools rapidly after sunset. In Albuquerque, this means beginning the scan 45 to 75 minutes after sunset during the months with significant daily solar load. Albuquerque's combination of high elevation, low humidity, and intense solar exposure creates favorable conditions for thermal contrast from April through October. Winter scans are less reliable because lower solar angles and occasional cloud cover reduce the differential loading that produces detectable contrast.
We walk a grid pattern across the roof surface, capturing overlapping thermal frames referenced to GPS coordinates. The thermal images are assembled into a roof plan overlay showing warm anomalies — suspect wet zones — against the cooling dry field. All images are saved with camera metadata intact: date, time, ambient temperature, and camera settings. This metadata is part of the report and supports the documentation chain for insurance or due diligence use.
Core sampling follows the scan. We pull cores at the centroid of each warm zone identified plus control cores in areas the scan read as dry. The cores confirm moisture content and verify the thermal read. In Albuquerque's low ambient humidity, the thermal contrast between wet and dry insulation tends to be sharp, and our scan accuracy against core confirmation is consistently high.
Limits of the Technique
Infrared scanning reads moisture in the insulation layer directly below the membrane. It does not penetrate the structural deck — deck corrosion and deflection are visual and probe findings, not thermal ones. On buildings where a steel deck is suspected to have corrosion from long-standing moisture, we inspect the deck condition from the interior or by core pull rather than relying on the thermal image.
The technique is unreliable on roofs with ballasted stone or pavers, on roofs where recent rainfall has uniformly saturated the full surface — there is no dry baseline to contrast against — and on roofs with photovoltaic arrays covering more than 30 percent of the surface, where the panels block the solar loading the scan depends on. We assess scan feasibility before scheduling and will advise when conditions are not favorable for a reliable result.
Rooftop HVAC equipment and mechanical units create localized warm zones around their bases that can appear similar to moisture anomalies in a thermal image. We flag these in the scan report and verify them by core or probe rather than treating them as confirmed moisture findings. Albuquerque's prevalence of rooftop evaporative coolers and refrigerant condensers requires careful attention to this distinction.
Frequently asked questions
How does Albuquerque's low humidity affect scan accuracy?
It generally improves it. In humid coastal markets, ambient moisture in the air and on roof surfaces can reduce thermal contrast. Albuquerque's extremely low relative humidity — often below 20 percent on summer evenings outside the monsoon season — means the thermal differential between wet insulation and the cooling dry membrane is cleaner. The high solar load from 300-plus sun days at 5,300 feet amplifies the contrast further. These are favorable conditions for infrared scanning when the scan is timed correctly.
Do you scan during the day or at night?
Evening, after sunset. Albuquerque summer daytime surface temperatures make daytime scanning unreliable — the radiant heat from the membrane surface masks the differential between wet and dry insulation below. The window 45 to 90 minutes after sunset, when the membrane has cooled but wet insulation retains its solar-loaded heat, is when thermal contrast is most reliable and the scan produces the most accurate moisture map.
Can the scan report be used for an insurance claim?
Yes, with the understanding that it documents moisture presence and location, not cause. If you need a report that also establishes whether moisture entered during a specific storm event versus pre-existing the event, we structure the report to address that distinction and will coordinate the documentation format with your adjuster.
Not sure if your Albuquerque building needs replacement or recover? Scan it first.
An infrared scan and targeted core pulls give you the moisture map needed to make a sound capital decision — without opening the roof across the full area.
