Infrared Camera/Thermal Imager for Leak Detection

Is anyone using an infrared camera/thermal imager to find roofing leaks? We are thinking about purchasing one, but were wondering if anyone has any experience with them or recommendations about which one works well for roofers.

Thanks for your help!

Thanks everyone for your help.

We are actually looking at the Flir I series and were planning to use it just to help out in locating the leaks once we have the repair job, not really offering the service to the clients. We still haven't decided if it's worth going ahead with, so would appreciate any additional feedback anyone may have.

We had a nuclear scanner that was about 1/3 the price. We were able to sell some jobs on it, however, the AEC was the regulatory agency we had to deal with and the fees and paper work was mind bogling. It was a sophisticated tool to provide for your clients, who really didn t appreciate its economic value. Unless you actively pursue customers and make it your primary business, just not worth it. We sold it to a company that specialized in roof surveys.
