Infrared Inspections

 

Infrared Inspection of Roofs

Flat roof membranes are the waterproof barriers between the outside elements and the interior of buildings. They come in a variety of materials and designs. They must be able to expand and contract, resist high winds and the effects of solar radiation and withstand foot traffic. It is easy to see why roofs leak.1

Normally there is little or no water within a flat roof assembly. When a leak develops, water enters the assembly and, depending on the type of insulation system, is either absorbed by the insulation or runs to the cracks between the nonabsorbent insulation. When water enters the roof assembly it is there for a long time, sometimes the life of the roof.

Thermal capacitance is the physical property of a material’s ability to store heat. The materials in roof assemblies have relatively low thermal capacitance, especially when compared to water. Water requires a lot of energy to raise its temperature and likewise must release a lot of energy to cool.

The physics used for thermal roof inspections is that dry roof insulation heats up and cools down faster than wet roof insulation. Infrared inspection goes beyond simply finding a leak by locating the extent of the moisture invasion of the insulation. To do this we require solar heating of a sunny day. Then at night, after the sun goes down and the roof surface begins to cool, the dry roof insulation cools faster than wet roof insulation.

Infrared inspections should be done under the right conditions to obtain the best infrared images. We require a different temperature between the day and night. For best results, here are some things to consider:

2
• Was it a clear sunny day?
• Is it a clear night (for good radiation cooling)?
• Is there little or no wind?
• Is the roof surface dry?
• Is the roof clear of snow, dirt and debris?

The type of insulation used on a roof will result in an infrared image that is characteristic of how that particular insulation absorbs water. Absorbent roof insulation acts similar to a sponge. The water migrates by capillary action throughout a complete roof board before it jumps to the adjacent board. This results in a checker board thermal pattern.

Nonabsorbent roof insulation creates a much different pattern when it becomes wet. The water is not absorbed and runs to the edge of the roof board. The water tends to collect at the edges of the boards resulting in a window frame pattern. Different patterns may result from other less common insulating systems.

There are many conditions that can produce thermal patterns that may look like they were created by wet insulation but are not, and others may mask the true condition of wet insulation. The ASTM specification C-1153 titled “Location of Wet Insulation in Roofing Systems Using Infrared Imaging” suggest performing verification of suspected wet insulation by core methods. The following are some examples of situations that may result in poor infrared inspections:

• Insulation with different R-values or different absorption characteristics which are commonly found in repaired areas.
• Different internal building temperatures.
• Extra gravel or bituminous left from construction.
• Warm or cold air exhausting onto roof.
• Re-radiation of heat from south or west facing walls.
• Wind.
• Internal sources of heat or cold such as lights, heaters, and steam pipes.
• Dirt, vegetation and debris.
• Walkway pads and buried steel plates.
• Blisters.
• Water ponding, steam plumes and water spray.

3 During the winter use the same process; however, winter surveys are more difficult because the temperature differences are usually less than on summer surveys (5F vs. 20F). If the building is heated, the added heat flow from the building through wet insulation will help enhance the winter thermal patterns.
Some safety reminders are:

• Do not work on a roof alone.
• Don’t walk backwards on a roof.
• Follow company and government safety regulations.

Infrared Roofs

Infrared Thermography Inspections Can Detect and Document Roof Moisture Problems.

Inspecting roofs using an infrared camera is a proven method for detecting trapped moisture problems in flat roofs. Infrared roof thermography can prevent equipment down time, production losses and help building owners and property management companies find roof problems when apartments below have become compromised by roof leaks.

Due to the high cost of replacing a damaged roof, infrared roof inspections should be performed whenever a building is purchased, sold or leased.

Infrared roof surveys provide the diagnostic information necessary for developing an effective roof maintenance program, planning capital budgets and for making informed decisions when considering roof repairs, replacement or resurfacing with one of the popular new roof coatings.

Water enters a roof through defects in the waterproofing layer(s) due to deterioration, tears, cuts, poorly sealed penetrations, seams, failed flashings or caps causing the insulation to become laden with trapped moisture. The building experiences energy loss because wet insulation has a lower “R” value than dry material thus providing less thermal resistance.
Water intrudes into the building’s interior causing damage and loss of productivity. If left in disrepair, the concrete deck absorbs water, the wood deck rots or the metal decking components rust. Infrared roof inspection is the perfect tool for detecting moisture intrusion and directing repair efforts to only the areas that need it, minimizing costs and maximizing repair dollars.

Our high-resolution Infrared thermal imaging cameras, detect trapped moisture as shown in the images above. Wet areas are identified and marked to show exactly where tactical repairs are to be made. By marking wet areas directly on the roof, they can be seen by building owners and roofing contractors after the survey is performed. Often, we find that the infrared survey shows is it is not necessary to replace an entire roof that only a few sections are “wet” and repairs can be made surgically to only these areas.

Here’s how an infrared roof scan works…

During the day, the sun radiates energy onto the roof and into the roof substrate, and then at night, the roof radiates the heat back into outer space. This is called radiational cooling. Areas of the roof that are of a higher mass (wet) retain this heat longer than that of the lower mass (dry) areas. Infrared imagers can detect this heat and “see” the warmer, higher mass areas, during the “window” of uneven heat dissipation. Heat loss and other IR services can be performed at the same time.

5

By using the information generated by a FLIR Infrared Camera report, the owner’s roofing professional can recommend cost-effective removal and replacement of wet components. Problem areas can now be corrected without the tremendous expense of replacing the entire roof.

Why FLIR Infrared?

We create detailed and professional Infrared reports documenting the entrained roof moisture. We designed the infrared reports so that roof professionals and building owners or property management companies will be able to use the information to verify the wet areas and write specifications to repair the roof. Our reports can be used to document roof conditions to ensure warranty coverage is maintained, to certify the roof substrate is dry prior to applying a roof coating material and for pre purchase inspections.

IR Cameras: Inspecting for Air Leaks in Buildings

9Infrared (IR) cameras are quickly becoming an indispensable tool for home inspectors. Reading the thermal images produced by an infrared camera during an inspection allows for quick and accurate identification of defects that may not always be immediately apparent to the naked eye. Infrared imaging is especially useful when looking for air leaks, including insulation defects, during an energy audit because it allows the inspector to actually view the apparent temperatures in a given area.

By purposely controlling the temperature and air pressure in the interior of a house, air can be forced inside through cracks and holes. Using an infrared camera, the sources of these air leaks can be quickly located and visually documented. Areas of insufficient insulation also become more apparent when viewed through an infrared camera and can be visually documented, as well.

How It Works

While there are other infrared tools available, such as spot radiometers and thermal line scanners, a thermal imaging camera is the most accurate device to use for energy-audit inspections. The camera reads infrared radiation in order to express heat differences and temperature signatures.

The camera sees light that is within the heat spectrum that exists just beyond the spectrum that can be seen with the naked eye. Differing heat signatures are displayed in the camera’s viewfinder as a gradient color scheme, with hotter areas displayed as brighter colors, and cooler areas as darker colors.

10

An inspector can view this information on the camera in order to make observations and find defects. By viewing the hottest and coldest areas, inspectors can collect valuable data about the building envelope. Images taken with the IR camera can be included alongside digital photos of the same problem area in the inspection report.

Setting Up for a Thermal Imaging Inspection

Because the IR camera shows differences in heat signatures for a given area, it is important to set up the testing conditions such that the temperature difference between the interior of the house and the air outside is as large as possible. The peaks of the heating and cooling seasons for any region are generally optimal times to gather thermal imaging data, since heat or air conditioning can be run in order to maximize the temperature difference.

All windows and exterior doors should be closed during testing. It is also helpful to move furniture away from walls so that they don’t block baseboards, and to remove curtains and blinds (or secure them out of the way) so that accurate readings can be taken at areas typical for leaking air, such as at floor-wall joints and window frames.

Achieving a 15° to 20º difference in temperature is ideal. The heat or air conditioning should then be turned off, and the inspector should wait at least 15 minutes before commencing with the IR inspection.

Insulation Defects

Once a solid difference in temperature has been established between the interior and exterior of the house, insulation defects can be viewed by the camera. By looking at the difference in apparent temperatures, hot and cold spots can be identified as areas that may have missing or inadequate insulation. If a potential problem area is pinpointed using the infrared camera, the insulation in that spot should be examined to verify that it is an issue and to gather more details on the exact nature of the insulation problem. Was insulation moved during a fixture installation and not properly replaced? Is the thickness of the insulation inadequate for the application? These are the types of details inspectors can gather after locating an issue with the insulation.

Finding Air Leaks

Finding the sources of air leaks using thermal imaging requires some additional setup beyond what is needed to find insulation problems. By changing the air pressure of the interior in relation to the exterior, air flow can be increased to force air through cracks and holes. With the warmer or cooler air from the outside flowing into the house through the cracks and holes, inspectors can use thermal imaging to locate the sources of these air leaks.

The best way to pull air inside through cracks and holes is by using blower door equipment. The blower door test creates ideal conditions for pulling air in through leaky spots, and these spots are then visible in the thermal image. If blower door equipment is not available, a house’s exhaust fans and ventilation system can be used to create similar (though less controlled) conditions, allowing useful data to be gathered.

Areas to Check

Knowing what areas to examine for air leaks and insulation issues will speed up the process of finding problems. Infrared equipment is extremely useful for pinpointing the locations of air leaks and specific spots where insulation is inadequate, but it is also useful to know where to start looking for such defects. Air leaks can often be felt with the hand during a blower door test. Also, during cold months, areas of insufficient insulation may be apparent due to the change in temperature in specific spots.

Inspectors can start with the following areas, or any area that is already suspected to be leaking air or lacking inadequate insulation:

11

• light fixtures;
• electrical receptacles;
• windows and doors;
• attic access;
• attic insulation;
• basement rim joists;
• cellar doors;
• crawlspaces;
• ductwork;
• plumbing penetrations, and traps under tubs and showers;
• plumbing vent pipe penetrations;
• chimney flue and fireplace surrounds;
• dropped soffits;
• dropped ceilings;
• kitchen soffits;
• air handlers;
• cracks between partition top plates and drywall;
• utility chases; and
• baseboards.

By using thermal imaging, inspectors can more quickly identify problems with insulation and the sources of air leaks. Understanding the basics of infrared technology, including how to set up conditions for gathering data, and knowing specific areas to examine, will help inspectors make the best use of thermal imaging cameras during an energy audit.

IR Cameras: Electrical Inspections

Thermal or infrared (IR) imaging in the practice of building inspection has been used to inspect electrical systems for some time now and its use has steadily grown increasingly popular. Since components in electrical systems almost always overheat before they fail, problem areas are more easily and safely found when viewed through an IR camera. 13

Infrared imaging allows apparent temperatures to be seen as gradient colors, with hotter spots displayed as brighter colors, and cooler (and wetter) spots displayed as darker colors. When a malfunctioning electrical component or connection is generating more heat than it should be, its apparent temperature will make it stand out right away when viewed through thermal imaging.

What kinds of problems can be detected?

During an inspection, electrical equipment, such as distribution panel boards, switchboards, contacts, transformers, receptacles, and service and control panels, can be examined through an IR camera. By viewing apparent temperature differences, inspectors can identify and document problems, such as loose connections and overloaded circuits, which are the most common causes of electrical fires. Other issues, such as transformer cooling problems, induced currents, arcing, and motor-winding faults, also become readily apparent.

Thermal imaging can detect electrical issues that include:

• excessively hot or loose connections;
• overloaded wiring;
• overloaded circuits;
• overloaded transformers;
• overloaded motors;
• arcing; and
• excessive harmonics.

Advantages of Using an IR Camera for Electrical Inspections

Because viewing apparent temperature differences through an IR camera requires no physical contact and can cover a lot of space in one sweep, no other technology allows electrical faults to be found as safely and as quickly as thermal imaging. Another important benefit is that it allows problem areas and components to be located before damage from any serious failure or electrical fire occurs. This helps ensure safety. It can also save money that might otherwise need to spent on extensive repairs.

Here’s a list of advantages of using an IR camera for electrical inspections:

14

• It’s non-contact, which helps ensure a safe inspection.
• It’s fast and accurate.
• It helps identify problems before they cause serious failure or an electrical fire.
• It’s non-intrusive, so there is no interruption of power during the inspection.
• It can be used as part of inspections that are conducted as preventative maintenance.
• IR equipment is light and portable.
• It provides documentation of problems.

Inspection Tips

When inspecting electrical systems with infrared thermography, it is necessary to use an IR camera. Tools such as spot radiometers and thermal line scanners alone are insufficient for providing documentation and qualitative assessments of electrical systems.

Before beginning the inspection, it is useful to ensure that access is available to all areas and components that will be inspected. The electrical systems can then be examined while operating under a normal load. Any open panels or enclosures are typically inspected first. A panel that shows signs of moisture, is heavily rusted, is buzzing or arcing, or that generally shows any signs of being unsafe should be reported but not opened or touched. Infrared images can be taken from a safe distance for documentation.

15

Panels and other areas to be inspected that are deemed safe through visual inspection first, such as receptacles, can be examined by line of sight with the infrared camera. It is quick and easy to view all components in most service panels with thermal imaging, and problem areas will be visible as apparent temperature differences. These areas can then be documented by including an infrared image alongside a standard digital photo in the inspection report. One practice that may be helpful is to document similar components operating under similar loads. The side-by-side comparison of a properly functioning component and a similar one that is not operating correctly is a good way to gather additional details to present clear documentation without exceeding InterNACHI’s Standards of Practice for conducting a safe electrical inspection.

The thermal images taken are most useful when they are clear and in focus, allowing the most detail to be captured. The same principles apply to standard, visible-light images taken at the same time for comparison. These complementary images should be captured from the same angle and vantage point as the infrared images so that heat signatures detected by thermal imaging can be identified easily with the corresponding components in the visible-light or digital photo.

Infrared cameras that also incorporate the ability to switch over to standard digital photography are especially useful for electrical inspections because they allow for comparison without having to move or change position between photos.

When providing documentation after the inspection, it is useful to include the following:
• The exact locations of any problems found;
• A description of the issue that also includes any nameplate data, and phase or circuit numbers;
• Copies of thermal images and corresponding visible-light or digital images;
• The field of view (F-stop) of the infrared lens;
• The manufacturer and model of the camera used; and
• Any information regarding conditions that may affect the results, their repeatability, or the interpretation of the problem found.

Using infrared cameras for electrical inspections is safe and quick, and is a great way to document problems that convey useful and easy-to-understand details for property owners. Inspectors will benefit from utilizing this technology in the field.

IR Cameras: Inspecting Roofs

Since the 1970s, infrared (IR) thermography, or thermal imaging, has been used for inspecting flat and low-slope roofs to check for moisture entrapment. Employing IR cameras for home and commercial roof inspections is on the rise, with millions of square feet now being inspected using this technology every year.

Replacing damaged roofs can cost as much as $8 to $10 per square foot, and billions of dollars are lost every year because of premature roof failure.

16

The main causes of premature roof failure and high maintenance costs are moisture intrusion and undetected wet insulation inside the roofing system. Because thermal imaging makes apparent temperature differences viewable, it is excellent at finding moisture and then documenting problem areas during roof inspections. The roof absorbs heat during the day and releases it when the temperature falls later. Wet areas release heat slower than dry areas. Because of this, the wet and dry areas are readily viewable in a thermal image, which displays apparent temperature differences as gradient colors.

Inspectors can familiarize themselves with this application of thermal imaging to expand their IR services to diagnose problem areas on roofs that have trapped moisture, which can lead to structural problems and expensive repairs.

Advantages of Using IR Imaging for Roofs

Thermal imaging is non-invasive and allows inspectors to scan large areas very quickly. More traditional methods require a grid-type contact search, which is very time-consuming for inspectors who choose to walk a roof for inspections. Core sampling and other invasive testing are destructive and beyond InterNACHI’s Standards of Practice. Using an infrared camera to locate areas of moisture intrusion and wet insulation is quick, accurate and inexpensive compared to other methods. Since IR imaging allows problem areas to be located before severe symptoms appear, catching and addressing issues as they develop can avoid significant damage. Thermal imaging can also be performed from an elevated vantage point, allowing an even greater area to be examined at once, and eliminating the need to lug equipment up and down various roof elevations.

Here‘s a list of advantages of using an IR camera for roof inspections:
• It’s fast and accurate.
• It can identify small problem areas before they become larger.
• It provides a thorough assessment of compromised and damaged areas.
• IR equipment is lightweight and portable.
• It provides visual documentation of problems.
• It is non-invasive.
• It can be used for inspections that are conducted as part of regular home maintenance.

There are few disadvantages to using thermal imaging for inspecting a roof. The main things to be aware of are the roof’s composition and the weather conditions. Both of these factors can influence the ability of infrared technology to provide accurate and useful information.

Weather Conditions

Though the principles involved are the same, detecting moisture intrusion using an IR camera is different for inspecting a roof compared to detecting moisture intrusion at the interior because exterior environmental factors play a larger role in determining whether the data can be accurately collected. Because of this, it is important to conduct IR roof inspections under optimum weather conditions.

17

There are four weather-related factors that can influence exterior surface temperatures over a roof’s wet areas compared to dry areas. They are:
• The difference between interior and exterior temperatures;
• The rate of temperature change in the hours before viewing the thermal images;
• The amount of solar loading; and
• Wind speed.

The best weather conditions for conducting an infrared roof inspection include:
• Winds of less than 15 mph;
• Sunny and clear conditions on the day prior to the inspection; and
• A quick decrease in the ambient temperature right before collecting images.

An infrared inspection during warm weather relies on solar loading to create the apparent temperature difference between wet and dry spots, and is best performed at dusk, when the difference will be most extreme. Imaging during cold months is made possible by creating a large inside-to-outside temperature difference in the building, which is another way to allow the wet and dry spots to be viewed.

Roofing-Covering Materials

It is important for inspectors to know the composition of the roof to be inspected with an IR camera because the roof-covering materials affect how well thermal imaging can detect moisture. Most common materials pose no problems. Any commercially available rigid insulation board, as well as composite boards and tapered systems made from the same materials, can be “read” through thermal imaging. This includes organic fibers, perlite, cork, fiberglass, cellular glass, polystyrene, polyurethane, isocyanurate and phenolic insulation materials.

Inverted roof membrane assemblies with extruded polystyrene insulation between the ballast and protective membrane are poor candidates for thermal imaging inspection, although they are not common. Some other construction types that can pose problems include roofs with concrete pavers, roofs with lightweight concrete or gypsum, and highly reflective metal roofs. Infrared imaging can still be used in many of these cases, though it may be more difficult to read the images.

Inspection Tips

It is best to have completed a visual inspection of the roof prior to thermal imaging to determine the most effective procedure for collecting images, as well as to identify access points, safety hazards, and any heat sources beneath the roof that may show up during imaging. The attic and underside of the roof can also be examined in order to note any conditions that may affect imaging, and to identify potential problem areas that can be confirmed later using a moisture meter and further investigation.

18

It is helpful to know the design and composition of the roof, as well as exactly what type of insulation has been installed. This will help determine how thermal imaging can be best employed to gather data. If possible, knowing a little about the history of the roof in relation to any previous problems can also be beneficial. Note the flashing and penetration details, as moisture intrusion at these points may indicate inadequate or missing installations.

Set up the IR camera so that large sections of the roof can be viewed successively. The angle for viewing is best at greater than 20° from the roof’s surface. As wet spots are located by apparent temperature differences from surrounding dry spots, they can be examined more closely. A moisture meter will help confirm these areas as problems. Once the problem spots are located, they can be documented by taking an image with the infrared camera to include in the inspection report alongside a digital photo. These spots can also be marked on the roof with chalk so that they will be easy to find again later while plans for repairs are being developed.

Inspectors can benefit greatly from utilizing IR technology in the field for roof inspections, potentially saving property owners the cost of expensive repairs.

What is Infrared Thermal Imaging?

In the most basic terms, infrared energy is heat. The infrared spectrum is beside the visible light spectrum that allows us to see with our eyes. All objects give off some level of infrared energy. The actual amount given off is determined by the material properties of the object and its environment. With specialized equipment and training it is possible to “see” and interpret infrared images. Infrared Thermal Imaging is the use of specialized equipment to “see” in the infrared spectrum. Originally developed for military then industrial applications, the technology has finally made its way to the residential inspection industry.

This process is still a “visual” inspection. Contrary to what some companies and advertisers would have the public believe, this technology does NOT allow you to “see inside the walls.” With proper training a qualified operator can make educated interpretations of what is occurring inside the wall based on the thermal image. Infrared Thermal Imaging still has certain limitations in its use. Glass and reflective surfaces are opaque to this infrared technology and the images seen on these surfaces are reflections not the thermal properties of the surface. It is absolutely essential that the operator of the equipment be properly trained in Thermography, Heat Transfer and Thermodynamics. As an Infrared ITC Certified Level 1 thermographer, I have this training.

Furthermore, not all-infrared equipment is equal. There are low priced, low powered, low sensitivity cameras on the market that are little more than infrared hunting scopes. To insure a proper infrared inspection it is necessary to use infrared cameras developed for home inspections. We use the FLIR T420 High resolution that was designed specifically for home inspections.

Can Infrared Thermal Imaging see through the walls like an X-ray?

Absolutely NOT! An infrared camera simply sees the surface heat of whatever it is looking at, in a completely passive manner. A properly trained operator can interpret the images to determine some of what is happening behind a surface. As with any technology, there are limitations, making proper training and quality equipment essential.

How is Infrared Thermal Imaging useful or important to a home inspection?

Hot or cold spots can be indicators of problems and the infrared camera is designed to allow efficient scanning of the home to find these problems.

Moisture Intrusion, Leaks, Condensation

Because of the thermal properties of water and the phenomenon of evaporation, active wet spots will generally show up as “cold” spots in an infrared picture. While there is other equipment that detects active moisture, it is spot specific. Meaning it works for a very small specific location. Infrared Thermal Imaging, with the proper equipment, allows the operator to quickly and efficiently scan larger areas for suspicious active moisture spots. When a suspicious area is found, the area can be checked with a moisture meter to confirm or deny the presence of active moisture. Often with our sensitive camera we can even determine where the moisture came from.

Electrical Problems

Hot spots are often found with electrical problems. Electrical outlets, switches, wires or circuit breakers that are malfunctioning, overloaded, or compromised in some manner. These are very dangerous as they can easily lead to a catastrophic fire. Our Infrared Thermal Imaging process allows us to easily and efficiently scan for these electrical hot spots that may not have been visible to the naked eye and would have escaped notice. If the scan gives indications of problems follow-up investigation is called for to verify the problem and resolve it.

Insulation Anomalies

Insulation anomalies are also alarmingly common in construction, both new and old, in our area. With energy costs soaring, these deficiencies can lead to huge energy costs. Again, our Infrared Thermal Imaging process allows us to efficiently scan the home and identify areas that are improperly or incompletely insulated. Because this scan is completed from inside, we can see areas that may otherwise be inaccessible and therefore not visible to traditional visual inspection procedure.

Improperly Connected HVAC Ductwork

If your HVAC flex duct has not been properly sealed you could have significant leakage at joints in the attic. Infrared Thermal Imaging can identify this problem, if the connection is visible. We have found both poor connections at plenums and registers in our infrared scans. These situations are simply costing the homeowners money and comfort. Left unfixed, with the right atmospheric conditions, these can even lead to moisture problems from condensation.

Why is your inspection price not the lowest in the area?

Quality, high performance infrared imaging equipment designed for home inspections is VERY expensive, in the price range of around $10,000 plus. We use a FLIR camera specifically designed for home inspections. While we work to provide this revolutionary service at a reasonable price. We firmly believe in our training, equipment, and inspection process. We also believe that this technology is too important to perform an inspection without. It is an option to the customer but it is also insurance on one of the biggest investments in your life and comfort to your loved ones. If you are interested in a professional & current up-to-date inspection possible you have to remember you get what you pay for. Comparing our inspection to an inspection without a high quality infrared camera is like comparing apples to oranges.

Why don’t all inspectors have infrared?

This technology is very expensive, some inspectors cannot or will not invest that much back into their business. Others actually believe that Infrared “sees too much” and that it is too far beyond the required standards and may increase their liability. At TG Project Management, LLC we think disagree. We believe our clients deserved the absolute best inspection possible. We strongly feel that includes Infrared Thermal Imaging. With proper education on our part clients understand what the technology is capable of and what it is not. They benefit from the thorough inspection and we sleep better at night knowing we have done our best.
