Moisture in your roof's insulation reduces its energy efficiency and can pose a threat to the structural soundness of your building. In fact, wet insulation can cause deck deterioration, sick building syndrome and ultimately result in roof replacement. A visual roof inspection, although valuable as a guide, provides little data to accurately pinpoint moisture below the surface of the roof.
Moisture Verification:
Rooftop Infrared Moisture Survey - Wet roofing insulation conducts heat more rapidly than dry insulation. Using this principle, we apply sensitive infrared technology to detect temperature differentials across your entire roof area. This method quickly identifies areas with wet insulation, which are then marked for further analysis and possible removal.
Additional Techniques - Some roof conditions may require different types of inspection. Our knowledge of these conditions and our access to different techniques such as capacitance and Tramex meters assures you accurate results. Utilizing these techniques can be an alternative or a compliment to hand-held infrared survey.
Moisture Probe - Once skilled technicians have identified potentially wet roof sections using one or more of these non-destructive methods, they rely on moisture probe testing to verify the presence of moisture. The probes of this small tool are inserted through the roof to measure electrical resistance to verify wet roof areas.
Core Samples - A proper moisture analysis program requires
some level of physical testing in the form of core sampling,
which gives the quantity of moisture at the core site
as well as the roof construction. All roof cores are
immediately repaired with quality roof repair materials
to ensure waterproofing continuity.
Capacitance measures
the high dielectric constant of any water in your roof
system on a portable capacitance meter, which is systematically
maneuvered over the roof surface.
