Nuclear Roof Moisture Testing

The measurement method relies on the thermalization slowing of fast neutrons by the hydrogen atoms in water.

Nuclear roof moisture testing.

The readings can also be affected by inconsistencies in the roof components. Nuclear radioscopic roof moisture surveys are a form of non destructive testing used to detect and document moisture content within a roofing system. Nuclear surveys provide excellent information at low cost and substantially improve your roofing options. Core cuts are conducted in a moisture analysis because all of the.

Nuclear testing can also find standing water within the roof system and can read through multiple layers of insulation as far down. Our certified thermographers use state of the art cameras to capture the thermal signature of the roof s nighttime heat loss the infrared image pinpoints the extent of moisture damage and wet insulation within the roof. The presence of hydrogen atoms water slows the fast neutrons. Performed regularly nuclear surveys can help identify latent moisture within the roofing system.

Nuclear roof moisture surveys for flat roof inspections. During the testing a 5 x5 or 10 x10 grid is marked depending on what. This is done by extracting test samples or core cuts from the roof area. 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.

Nuclear backscatter methodology for flat roof inspections is a non destructive testing technique uses a radioactive isotope consisting of americium 241 with a beryllium target to emit high speed neutrons aimed at the roof. 5 1 excess moisture trapped in roofing or waterproofing systems can adversely affect performance and lead to premature failure of roofing or waterproofing systems and its components. 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. After a complete moisture analysis of the roof is conducted and all of the potential wet areas are marked on the roof plan it is time to determine the true moisture content of the roof system.

A nuclear roof moisture survey is the most accurate way to locate trapped moisture in ballasted roofs. Nuclear roof moisture surveys are a technique utilizing a radioactive isotope to emit high speed neutrons aimed at the roof from the roof surface. Impedance scans can be effective in identifying concealed and entrapped moisture within roofing or. Nuclear moisture detection is the only accurate method for testing ballasted roofs and the underlying sections of multiple construction roof systems.

It also reduces thermal resistance resulting in reduced energy efficiency and inflated energy costs. Roof cores are taken in both dry and suspect wet areas to verify the instrument readings. Finally the locations of the anomalies and the test cuts are marked on a roof plan.
