I've been writing estimates for about five to six years now, working as an adjuster, field adjuster, doing inspections, anywhere from commercial to residential roofing. So those are, it's something that I'm familiar with using Xactimate, knowing what materials and what type of work goes into repairing or rebuilding these roofs. It's something that I've done as well. I worked in roofing for a very long time as well, and I worked in construction, so I'm very familiar with it.
