Infrared Testing Pitched Roof

The testing cannot be completed over wet or ponded areas and modified instruments are typically required for epdm roof systems.

Infrared testing pitched roof.

Infrared infrared thermography is conducted with the use of an infrared camera. When there s a leak in the waterproof membrane water can enter the roof system and saturate the insulation and underlying layers. Astm e1105 and aama 501 2 test methods are good overall methods commonly used to test exterior walls sloped glazing and shallow pitched roofs to help identify leak sources. Proactive annual or semi annual flat roof infrared surveys are a tremendous predictive cost savings tool for building owners and operators.

Thermal infrared nondestructive testing of roofs infrared thermography is the preferred method of finding roof moisture because 100 of the roof is surveyed and all areas of wet insulation can be found during the thermal survey if properly conducted. Roof assemblies may be either warm or cold a warm roof is designed with all layers resting directly on one another. In our level i thermographic applications course we go into detail on safety pre inspection actual infrared inspection and the post inspection items. A low pitched roof has a slope of less than 3 12 and uses the same variety of draining system.

Day or night on a roof it is critical to always be with a qualified escort. Infrared roof surveys are the ideal tool for detecting moisture intrusion and then guiding repair efforts to only those areas which need it minimizing costs and maximizing serviceable life of the roof. Over the past 20 years infrared thermography has become a popular test technique for helping to detect latent moisture within flat and low slope roofing systems. An infrared camera detects the temperature of the areas within a roof system and identifies temperature differentials throughout the area.

This practice includes ground based and aerial inspections. Infrared survey infrared moisture surveys provide an economical way to identify specific areas of wet insulation and moisture present in the existing roof system. But plan on a preliminary daylight walk around to help you identify potential hazards and to visually inspect the roof. If moisture laden roofs are left in disrepair the metal decking components rust the concrete deck absorbs water and the wood deck rots.

This astm testing procedure utilizes a calibrated spray rack with specific water pressures nozzles and distances to wet a wall with water at the rate of five gallons per square foot per hour.
