A commercial roof can appear to be perfectly fine while moisture is silently building beneath the surface. They are often masked until a stain, material damage, mold, or costly structural damage occurs from small leaks, wet insulation, and trapped water. That is why relying only on the information of what the eye can see may not be enough.
An infrared commercial roof inspection applies thermal imaging technology to detect temperature across the surface of a roof. Let’s check the full blog below to learn how infrared commercial roof scans are better than visual inspections.
A thermal camera sees heat; it does not just take a normal photograph. Various roofing materials heat up and cool down at different rates during the day.
Wet insulation typically performs differently than dry insulation because the presence of water affects how heat is absorbed and released. In appropriate conditions, areas where moisture is trapped can stay warm longer than the rest of the roof surface as it starts to cool.
In an infrared roof moisture survey, a professional scans the roof with thermal equipment. Thermal images produced this way can exhibit strange temperature distributions that may be a sign of areas needing further investigation.
It is not automatic proof that all temperature differences are moisture in the scan. It assists roofing professionals in identifying suspicious locations for additional testing and verification.
The greatest benefit of thermal imaging for roof leaks is its capability to detect moisture issues prior to them becoming readily apparent on the interior.
A case in point would be that of a roof that has a small hole or membrane break allowing rainwater to enter the insulation. No stains may be evident on the interior ceiling. But if an infrared scan is taken at the correct time, wet insulation will sometimes show a thermal pattern that differs from surrounding dry areas.
This gives roofing professionals an added data point that would not be available through sight alone.
Infrared scanning will identify the areas of potential moisture buildup within each type of commercial roofing system. Scanning may also be employed to identify:
When certain areas are flagged, technicians can utilize different inspection techniques to determine if moisture is in fact present.
Infrared roof scans are most effective in the right conditions. In general, the roof has to undergo enough solar heating or other temperature change that differences between wet and dry materials reach a level where they can be detected.
Professionals will, therefore, account for the climate (including roof construction and surface materials), time of day, and rainfall history to determine when to reasonably conduct a scan.
An infrared inspection carried out at the wrong time may not be able to provide useful thermal contrast. So planning it well is essentially the first step towards getting meaningful results.
A non-destructive roof inspection allows you to find issues without damaging anything.
Rather than removing large sheet areas of roofing materials to search for moisture, technicians can quickly focus their attention on the first areas identified by infrared imaging. Then, it allows targeted verification where needed.
This may minimize unnecessary interruptions and allow homeowners to make more informed repair decisions.
Thermography is a very powerful tool, but it should never be a stand-alone tool for diagnosing anything. A thermal image shows temperature differences, but those differences can be due to several factors.
Experienced roofers use thermal images in conjunction with direct visual observations, roof history, atmospheric conditions, and construction techniques, as well as moisture verification methods.
This combination is a great way to differentiate between true moisture problems and regular thermal changes.
When a building owner suspects undiscovered moisture, persistent leaks, or wants additional details about an aging roof, an infrared roof scan can be especially valuable.
It might also be examined before significant roofing restoration or replacement. By knowing these wet areas early, the decision can be made early on which parts of the roof assembly may need to be addressed.
This strategy makes it easier for building owners to plan repairs early, rather than allowing hidden moisture to evolve into visible interior damage.
To begin with, a commercial roof may not be visibly affected when moisture and water start accumulating underneath it. While traditional inspections are still critical, infrared technology provides another avenue for inspecting areas that may otherwise be hidden.
Infrared roof scanning is capable of uncovering irregularities in thermal patterns, identifying areas that require further testing to assess the state of a commercial roofing system. When used together with professional inspection techniques, it assists in identifying concealed moisture and promotes improved repair and care choices.
The most expensive roof problems are not always the ones you can see. 911 Commercial Roofing can help you investigate whether you have an undetected leak, persistent moisture problem, or old roof structure.
Waiting for water stains on the ceiling to tell you there is trouble is too late. Call us today to book an infrared roof scan that can reveal what’s hiding beneath your roof surface.
