Moisture Meter For Flat Roofs

Flat and low slope roof designs to avoid moisture condensation problems flat roofs call up a whole new breed of building moisture problems how to avoid moisture traps under flat roofs avoid mold rot caused by moisture trapped under un vented flat roofs questions answers about the cause cure prevention of moisture problems in flat roofs and similarly hard to ventilate structures.

Moisture meter for flat roofs.

The moisture meter is another tool used in conjunction with thermal imaging in order to confirm the presence of moisture. It works more as a guide to read the thermal signature of the roof surface to discover the areas where it appears there is moisture. If the material is wet the dielectric properties of the material would produce a higher meter reading than it would if the material were dry. It involves placing a moisture meter on the surface of the roof to send a safe electric current into the roof without penetrating the roof membrane.

Roofing professionals have been using thermal imaging cameras for years to pinpoint water intrusion find moisture beneath the. Tramex moisture inspection tools for roofing provide the fastest simplest most economical safest methods of locating moisture damage. From the time a flat roof has been installed it should be maintained and inspected on a regular basis with problems and defects attended to and corrected as soon as they are located. Ideal for water leak detection in roofing materials and integrity testing.

Finally a major disadvantage is that since the nuclear meter samples about 2 square feet of roof at each grid point and most surveys are taken on a 10 x 10 grid a nuclear moisture survey sees only about 2 of the roof. If necessary a non penetrating moisture meter can be used to confirm the presence of trapped moisture in the roof assembly. Flat roof moisture meters. Flat roof ir surveys allow for nondestructive identification of specific areas on flat roofs where moisture has infiltrated the substrate and is deteriorating the insulation r value of the material reducing the strength of the overall roof system and negatively impacting the energy costs required to maintain the internal working environment.

This can lead to expensive damage from the rot which often develops and if left can weaken the roof structure. Roofing moisture meter product. Dec scanner is a mobile non destructive impedance scanner designed for the instant surveying of moisture conditions in roofing and waterproofing systems per astm d7954. A thermal imager alone cannot verify the existence of moisture.

Upon returning to the roof during daylight hours further analysis is conducted by the roofing contractor and infrared technician to determine the source of the moisture in that area.
