Roof Moisture Survey

The survey commenced at approximately 7 45 p m.

Roof moisture survey.

By the time the scan commenced the surface temperatures were sufficiently cooled to allow necessary temperature differentials. If a set of drawings or roof plan is not available prepare a plan and report sheets for each section being surveyed or better still use the tramex moisture mapping app. 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. Moisture surveys are conducted using a prelocated grid pattern throughout the roof area at which the device is placed and readings are recorded.

The grid pattern is typically 5 to 10 feet apart. 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. A nuclear roof moisture survey is the most accurate way to locate trapped moisture in ballasted roofs. This only works when there is a direct line of sight to the underside of the roof which obviously has limitations.

The nuclear technology is able to distinguish between multiple levels of moisture and can operate in a wide range of weather conditions on any type of slope roof. An on roof infrared moisture survey is a very economical method to determining the state of your flat roof.
