We thought we had located that vendor partner. It went well for awhile, but eventually we started to notice the inspections had slipped, and were not happening with the regularity we intended. When it worked, it worked great. And then it didn't work any longer. It is apparently the case that technology also encompasses the human element - who knew!!
So last year when attending a property expo, we paid particular attention to roofers, and asked each one of them whether they might offer an inspections program that we could contract for. Out of at least 10 roofers we talked to, I believe there might have been one or two who replied yes to that question.
This month we're having a lunch & learn with that vendor. We'll let you know how it goes. In the meantime, if you know a roofer who provides this service on a "portfolio" basis, send me their info.
In return I will share what I learn with you one on one.
