Roof Moisture Survey

Moisture surveys are conducted using a prelocated grid pattern throughout the roof area at which the device is placed and readings are recorded.

Roof moisture survey.

The survey commenced at approximately 7 45 p m. A nuclear roof moisture survey is the most accurate way to locate trapped moisture in ballasted roofs. An under roof moisture survey is accomplished when the thermographer determines differences in mass between and wet and dry substrate by looking up at the roof from the inside of the building. This only works when there is a direct line of sight to the underside of the roof which obviously has limitations.

The damage from a leak in the membrane can be at a minimum a nuisance inside the building but the damage to the roof from the trapped moisture can be very costly. To perform a non destructive flat roof moisture inspection to astm d7954 with the dec scanner first ensure that the surface is free of debris and is dry from rain or dew. The infrared roof moisture survey was conducted to locate and define areas of moisture insulation within the roof system. The plotting of wet areas is derived from the recorded readings and identified on a roof plan.

The grid pattern is typically 5 to 10 feet apart. An on roof infrared moisture survey is a very economical method to determining the state of your flat roof.
