How An Infrared Survey Works:
Wet roof insulation absorbs more solar energy from the
sun during the day than dry insulation. As the sun sets, the
nighttime cools the roof surface. Wet insulation retains
more solar energy than dry insulation. These temperature
differences are detected by the infrared camera. All full
service scans are performed using a mid-wave IR camera
with a 2.5 - 5.6 spectral range. Suspected wet insulation is
verified through core cuts and/or a Roof Moisture Meter.
Core cuts are taken to establish acceptable levels of
moisture. Confirmed wet areas are marked out on the
roof surface with paint.
How A Moisture Meter Works:
During the daytime, readings are taken and recorded in
random locations and at wet areas found by the infrared
camera.
Fast neutrons are emitted
from the source in the Roof
Moisture Meter into the roof
system. The presence of
hydrogen in the roof system
slows the neutrons. These
slowed neutrons as well as the fast neutrons are
detected by the Roof Moisture Meter. A reading is
displayed in the digital readout and gets recorded.
Core cuts are taken to determine a baseline for dry roof
materials. Wet areas of insulation are marked on the
roof surface with paint.
