The following sections are examples of defects found during our inspection process and examples of the power of infrared technologies.
Active roof and wall leaks. As you can see below active roof leaks may not be visible until long after they have been in the ceiling cavity causing damage. The digital photo below shows no visible signs of an active roof leak, yet the thermographic image shows a clear outline of the exact location of the active roof.
The infrared image below show active water migration at a window system on the second story of a home. This would not have been seen without the aid of the infrared camera. Our following analysis found that the siding was completely decayed and required framing, siding, and insulation replacement.
The infrared image below shows water migration into a wall cavity from failed caulking. Caulking may seem like a minor issue until you find it has caused substantial damage to your wall system. When this composite siding was probed it fell into sawdust along with the framing in the wall system.Our most common find during the thermal infrared inspection is water migration from an active roof leak as seen below. As you can see in the digital photo there is generally no visible signs of a problem. The infrared leaves no doubt there is an active and substantial leak.
Infrared roof inspections are one of the most important uses of infrared technology. The infrared analysis of a roofing system can save thousands to hundreds of thousands of dollars by pin pointing roofing failures. As you will see in the thermographs that follow infrared findings are very dramatic and clearly delineate the scope of the roofing failure. The infrared analysis below shows how obvious water that has migrated below a roofing membrane can be. The yellow inside the marked line is water migration.
The two thermographs below are taken at night. The best time to see temperature differentials in the roofing membrane. This dramatically increases the visibility of the active leaks.
Because of the dangerous nature of electrical components the infrared inspection of the electrical system is a critical part of your inspection process. Do not proceed with an inspection without knowing if your electrical system has a serious, unknown, unseen electrical short that could be a serious fire hazard. Some electrical issues that infrared can reveal include:
- Overheated wiring glows. Visible only with Infrared Inspections unless it's already on fire!
- Overheating wall switches or plugs? Readily visible with infrared.
Plumbing leaks are a major problem in homes. A small leak can go on undetected for many years before it damages the structure enough to show on finish work. Active leaks at tub drains, shower enclosures, sink waste lines are very hard to pin point unless thermal imaging is used.
Energy Loss, Energy Audit
The infrared thermograph below shows how clearly thermography can find missing insulation in a wall cavity. This undetected heat loss would dramatically increase energy costs and reduce the comfort of the occupants of the home.
Other benefits of an infrared inspection for energy loss are:
- Missing insulation in walls and floors is typically not apparent unless infrared technology is used.
- Locate cold / hot spots. An infrared inspection can lead to improved comfort indoors.
- Leaking door and window seals. Infrared can save thousands of energy dollars each year. Know where your leaks are before you buy.
Exterior Building Envelope Inspections
Water migration into the exterior sidewalls of a building is a major problem in the Pacific Northwest.
Many times wasps will nest in the walls of homes. Infrared can show the exact location of hives and nests.
Condensation or leaks within walls breed mold or bacteria growths. Moisture is often apparent early on only if you use thermography. Mold growths in hidden areas generate a unique heat signature through building materials and are visible only with Infrared thermography.
Infrared can quickly identify cold floors or walls within a home. Checking conditioned air temperatures leaving registers is a breeze with Infrared. Discovering poorly or disconnected supply or return ducts is also possible using Infrared.
Radiant Floor Heating
One small break in radiant floor heating system can have a large impact. Breaks are easy to identify and fix with infrared. No need to pull up the entire floor when one tile will do for a repair.
Infrared features hundreds of other uses that we are happy to discuss with you!
