Infrared Roof Leak Detection in King & Snohomish County

Residential & Commercial Thermal Moisture Surveys


Most roof leaks are misdiagnosed because water rarely enters where it appears inside the home. Infrared technology allows us to detect hidden moisture beneath the surface, revealing the true path of water before it causes further damage.


Roof leaks are rarely located directly above the stain you see inside. Water can travel along decking, framing, insulation, and structural components before finally becoming visible. The visible damage is often far from the true source.


With over fifty years of roofing experience and more than two decades working with infrared technology, leak detection is approached with precision, not guesswork.

Experience comes first. Technology supports it

Example of our Infrared Roof Leak Report

Real Example. Real Results.

Infrared roof leak report

This is an example of a real infrared roof leak inspection report.


It shows exactly where moisture is trapped behind walls and ceilings, even when there are no visible signs of damage.


Instead of guessing, we can pinpoint the source of the leak and track how water is moving through the structure.

What Infrared Leak Detection Reveals

 Infrared leak detection allows us to confirm what cannot be seen during a standard roof inspection.


Using thermal imaging, we identify hidden moisture, verify the point of entry, and track exactly how water is traveling through the structure.


This allows us to solve the problem at its source, not just where the damage appears.



With this technology, we can:


✔ Detect moisture trapped behind walls and ceilings


✔ Identify water intrusion beneath roofing materials


✔ Locate the true source of roof leaks


✔ Track how water is traveling through the structure


✔ Identify areas at risk for mold and structural damage

Featured Roofing Advice

Can a Gutter Cause More Water Damage Than a Roof?

Most homeowners assume the roof is the problem… but in many cases, it’s the gutter system causing hidden damage inside the home.

Cathedral Ceiling Homes

Cathedral ceilings present a unique challenge because there is no attic space between the ceiling and the roof deck.


When visual inspection is limited, infrared thermal imaging becomes a precision tool.

By scanning after the roof surface has had time to cool, temperature differences reveal areas of trapped moisture beneath the roofing system. This allows for targeted repairs without unnecessary removal of large roof sections.

Verification Through Moisture Testing

Infrared imaging identifies temperature patterns consistent with trapped moisture.

When confirmation is needed, a moisture test is performed to validate the findings.

Some homeowners are understandably skeptical when viewing thermal images for the first time. 


That is why verification matters.

  • Infrared reveals the pattern.
  • Moisture testing confirms the presence of water.


This two-step process ensures repairs are accurate and necessary.

  • No assumptions.
  • No unnecessary tear-offs.
  • No inflated scope of work.

Commercial Infrared Roof Surveys

Flat and low-slope commercial roofs can hold moisture long before visible failure occurs. Saturated insulation beneath membrane systems often goes undetected until major interior damage develops.


Infrared thermal surveys allow for non-destructive moisture mapping across large roof areas, including:


  • TPO systems
  • EPDM membranes
  • Modified bitumen roofs
  • Built-up roofing systems


This infrared image shows moisture beneath a flat roofing system, identifying the true source of a leak that cannot be seen with the naked eye. By pinpointing the exact location of water intrusion, infrared technology often eliminates the need for unnecessary full roof replacement.


Surveys are performed after sunset once the roof surface has cooled. Trapped moisture retains heat differently than dry materials, revealing affected areas.


This allows building owners to make informed decisions based on data, not speculation. Instead of replacing an entire roof unnecessarily, only compromised sections may require repair or replacement.

Real Case Study: A Leak That Traveled Over 200 Feet

One of the most challenging leaks I’ve ever diagnosed was on a large commercial building where water was appearing near a critical equipment area.


The affected equipment was extremely large, and if it had sustained water damage, it could have caused major operational disruption.


At first glance, the leak appeared to be coming from the flat roofing system directly above the problem area.


But something didn’t add up.


Using infrared thermal imaging, I began scanning the roof and tracking how moisture was moving beneath the surface. Instead of focusing on where the water was showing up, I followed the heat patterns to locate the true source.


The actual source of the leak was nearly 200 feet away.


Water was entering through a parapet wall, traveling underneath the flat roofing system, and finally settling near the equipment, far from where the problem appeared.


The issue had nothing to do with the roof itself.


The building engineer was present during the inspection and watched the entire process unfold. After seeing the results, he said:


“Steve, you made a believer out of me.”


He immediately requested an estimate to repair the parapet wall, which ultimately solved the problem at its source.


This is exactly why proper diagnosis matters.


Most leaks are not where they appear. The key is knowing where to look.

A Pioneer in Infrared Leak Detection

Long before handheld thermal cameras became common in roofing, advanced infrared technology was already being used for roof diagnostics.


In 2001, after nearly three years of research, an aerospace-grade cooled infrared camera was acquired. The system required an argon cooling cylinder and represented a significant investment at the time.


The first commercial infrared scan was performed on a bowling alley experiencing severe water intrusion. Contractors had quoted the owner $34,000 to replace the entire flat roof.


The infrared scan revealed that while the flat roof appeared saturated, the true source originated from a small penetration at the peak of an adjacent barrel roof. Water traveled beneath the membrane and structural components before settling in the flat section below.


A precise repair was made.

After the next heavy rain, the leak was gone.

The building owner later confirmed that avoiding full roof replacement saved approximately $34,000.


That project established a reputation built on precision diagnosis, not unnecessary replacement.

Early Infrared Roof Diagnostics - 2001

Aerospace grade cooled infrared system used for advanced roof leak detection. Required argon cooling and was among the earliest uses of thermal imaging in East Coast residential and commercial roofing. Thermal scans are performed after sunset once roof surface has cooled. Moisture patterns reveal the true leak source.
 

When Is Infrared Recommended?

Infrared is especially useful when:


✔ A home has a cathedral ceiling


✔ Leaks occur only during heavy or wind-driven rain.


✔ The leak source is not visually apparent.


✔ Commercial flat roofs require moisture mapping


✔ Insurance documentation is needed.


✔ Verification is required to eliminate doubt.


✔ Infrared is not used on every roof.


✔ It is used when structure, complexity, or verification demands deeper analysis.

    Complete Roofing System Solutions

    Infrared leak detection allows us to accurately identify hidden moisture and confirm the true source of a leak, but proper repair is what ensures the problem is fully resolved. In some cases, a targeted roof repair is all that’s needed, while other situations may require a full roof replacement depending on the condition of the roofing system. We also provide seamless gutter installation to ensure water is properly directed away from the home, preventing future issues. By combining accurate detection with the right solution, we help homeowners protect their entire roofing system. 


    We don't guess where the leak is. We prove it.

    Stop Guessing. Find the Source the First Time.

    If you’re dealing with a roof leak that keeps coming back or damage that doesn’t make sense, the problem is often being misdiagnosed.


    With proper inspection and infrared imaging, the true source can be identified and confirmed before more damage occurs.
