CRMS software programs, especially ones that perform conditional and economic analysis, are not a solution to all roof management problems. The programs are merely tools to assist in making decisions. They cannot apply human judgment, only mathematical calculations. A specific program s analysis process is prescribed by the programmers based on their experiences, skills and opinions. The users of CRMS software must apply their own judgment based on specific needs and situations.
School districts have different roof-performance histories and different levels of acceptable risk.
Unless you perform a thorough evaluation, a complete picture of the state of the roof cannot be developed. NDTE can take many forms including nuclear, electrical signal resistance and infrared. While the equipment can be expensive, the detection of unseen wet materials in a roof system can justify the cost. Hiring a subcontractor with this equipment is also a possibility. This provides the added benefit of having an operator with years of experience.
