Progeo Monitoring in Nashville, Tn is a leading national provider of Electric testing for roofing and waterproofing. This method is usually specified in new construction for membrane roofing under the term EFVM. We call our service Smartex EVM but the method of testing is the same as Electric Field Vector Mapping.
By using this low voltage technology, Progeo technicians can locate tiny leaks in the roofing that may become big leaks over time. The process allows the roofing contractor to make immediate repairs that we can test immediately for Quality Assurance.
This method is also much more effective than infrared analysis as it can pinpoint the ingress which may now be visually available.
