Roof
moisture surveys complement visual inspections since it is
virtually impossible to determine the extent of wet insulation
visually. An infrared imager senses the temperature of the
surface of the roof. Wet insulation changes the ability of the
roofing system to store and conduct thermal energy, thereby
causing changes in the temperature of the surface, which the
infrared imager can detect.
Flat roof
inspections can provide valuable information during
moisture assessments to building owners, facility
maintenance personnel, roofing contractors and roofing
material manufactures. Thermal imagers can be used to
assess various roof systems (BUR, EPDM, PVC ) for high
moisture content, due to the differences in temperature.
Wet insulation is the primary reason for dimensional
changes, decay, blistering, corrosion, causing complete
roofing failure. Moisture is the root of all evil when
it comes to flat roof systems.
It increases
heating and cooling cost because it decreases the
thermal efficiency of the insulation and adds unwanted
loads to a building system. A typical BUR (built up
roof) has a life expectancy of 16-20 years. This can
easily be extended by 10 years reducing the life cycle
costs if a predictive maintenance program (PDM) is
established.
Thermography will
identify saturated insulation due to workmanship, low
grade materials, design flaws and non existent
maintenance. This inspection should be conducted 6-10
months after construction and periodically thereafter to
detect inevitable flaws while problems are still small.
Flat roof replacement cost are in the area of $7.00 -
$9.00 sq/ft, compared to pennies per sq/ft it costs to
thermally inspect the roof on a routine basis. This
should be a no brainier for all building owners and
managers
