A building’s roof is often it’s most costly asset to replace. Savvy building and facility managers are increasingly aware of the cost/benefit associated with predicting roof repairs, and insurance companies are taking notice of this technology to assess the risk involved when insuring a building.
Roof moisture surveys complement visual inspections since it is virtually impossible to determine the extent of wet insulation visually. Our high-definition infrared cameras sense the temperature of the surface of the roof with accuracy of +/- 1 degree.
Flat roof inspections can provide valuable information during moisture assessments to building owners, facility maintenance personnel, roofing contractors and roofing material manufacturers.
Thermal imagers can be used to assess various roof systems (BUR, EPDM, PVC ). 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 caused by shoddy 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.
IRIS thermographers are trained in roofing materials, processes, management and inspection and provide complete roof inspections including marking off anomalies on the roof, verifying moisture with a moisture meter and providing core cut samples if requested.
