Nuclear Roof Testing

Nuclear moisture detection is the only accurate method for testing ballasted roofs and the underlying sections of multiple construction roof systems.

Nuclear roof testing.

The recorded reading is an average of the total roof assembly. Nuclear radioscopic roof moisture surveys are a form of non destructive testing used to detect and document moisture content within a roofing system. 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. 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.

A nuclear roof moisture survey is the most accurate way to locate trapped moisture in ballasted roofs. Nuclear testing can also find standing water within the roof system and can read through multiple layers of insulation as far down as 8. Roof cores are taken in both dry and suspect wet areas to verify the instrument readings. When is a nuclear roof moisture survey appropriate.

Testing is conducted over the entire roof area by sectioning the roof into grids 5 feet by 5 feet or 10 feet by 10 feet and recording the readings. Nuclear surveys provide excellent information at low cost and substantially improve your roofing options. Nuclear roof moisture surveys for flat roof inspections. Trapped moisture in your roofing system can lead to mold growth and health issues for building occupants.

Historically there have been five widely used testing methods for testing of horizontal membranes. Finally the locations of the anomalies and the test cuts are marked on a roof plan. Within the last two decades two new methods of testing have revolutionized the leak detection and integrity testing industry. Our professional infrared nuclear or capacitance impedance roof inspections can substantially reduce your roof repair and replacement costs by.

Spray testing flood testing capacitance impedance testing nuclear metering and infrared ir thermal imaging. A nuclear moisture survey provides accurate mapping of moisture concentrations by density within a roofing assembly. 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. Generally nuclear scanning can be completed to depths of as much as 7 inches and testing can be conducted in areas of ponded water.

The readings can also be affected by inconsistencies in the roof components. Today s building owners are saving hundreds of millions of dollars every year with infrared testing of their low slope roofs.
