Roof MoistureRoof Moisture Inspections / Mapping

When water is able to get into the roofing system (i.e. flat roofing system), the water will change both the thermal conductivity (how fast heat passes through the roofing system) and the thermal capacitance (how much heat will be stored in the roofing system).


Act Fast - Damage occurs quickly

The water damage to the roofing system is a problem that must be addressed immediately. Roof damage will only get worse with time, especially in colder climates where freezing temperatures will expand the water into ice, which will increase the rate of damage. Unrepaired water damage in the roofing system will lead to damge in other parts of the building structure, and ultimately to the building's contents.


Prompt roof inspections save significant amounts of money


The cost of replacing an entire roofing system is very expensive. To minimize maintenance and repair costs, the flaws that were the cause of the problem must be properly identified promptly. A professional roof moisture survey can significantly reduce the cost of repairs to roof damage because in many cases, by clearly identifing the actual areas of damage, repairs can be limited to those flawed areas without the need to replace the entire roofing system.


Two kinds of roof inspections - (Daytime/Nighttime)

Infrared roof moisture inspections are based on the physics of the difference in the thermal capacitance of the roofing system of the areas that are dry versus those that are now wet.  The wet areas of the roofing system will retain the stored heat absorbed during the day for a longer period after darkness than will the dry areas. This difference in the amount of heat that is stored in the roofing system is able to be viewed with an infrared camera approximately 1 hour after the sun has set. (These infrared roof moisture inspections therefore need to be scheduled during darkness.)  Areas that are viewed to be warmer (assumed to be wet) are typically then tested with core cuts and moisture probes to determine:  how much water is in the roofing system; at what level the water is moving through the system; and how extensive the damage is. Typically capacitance moisture meters are used  to minimize the amount of destructive testing required.

Capacitance testing is used on those roofing systems which are made from materials that interfere with the infrared camera's ability to observe changes in temperatures within the system.  When this is the case, capacitance testing using moisture meters and core cuts / moisture probes are used. (Capacitance Inspections of these roofs can be scheduled for the day time.)


Inspection cost low

Both Infrared and capacitance moisture inspections are performed for just a few cents per square foot, depending on the size of your facility and your documentation requirements.


Documentation Options

Documentation can take many forms depending on your needs and budget.

  • Paint-on (marking up of the roof surface with survey paint)
  • Summary of findings with square footages of areas
  • Core cuts findings
  • Infrared and Visual images of select areas
  • Written Report with documented findings
  • AutoCad drawings
  • Digital video of findings
