The days when a guy on a horse was used to deliver a message have been replaced with cell phones, emails, and texting. We now know the earth is not flat and we can take trips to outer space for around $250K. We have vehicles that are able to drive themselves better than some of us can. And with the help of infrared and electromagnetic technology, we are able to quickly and cost effectively identify moisture in a building's substrate. Water beneath a roofs' surface can cause major damage to insulation, decking, and framing if not found and fixed in time. IR technology can also help locate areas of heat loss due to the lack of insulation.
