[plumberx]

Good Job Gorden. love the video. I run into costumers all the time that can use your service. I had a costumer just the other day that could find out which way there main water service was going at what it was and wasn't picking up. 2" water main rule area. They really needed help bad. of cause to much to dig up and search but your cam would be great here.

Thermal / solar loading from the sun during the day heats up the roof system, during the evening the roof cools, however the wet insulation board below the roof system has a higher thermal mass and cools slower than the dry insulation board, thereby showing hotter

I believe the final picture did not have a thermal image attached to it

Why were the moisture signatures showing hot instead of cool? In the final photograph, I saw no anomoly.
