Gary was very prompt, very nice, and and very knowledgable.  He gave me a lot of pointers on how to take care of a roof, as well as some important questions to ask roofing contractors.  He produced a nice report (could have used a little more detail, but still very usable) and had it emailed to me the same day.  I am a very handy homeowner, but roofing is well outside of my experience & comfort area, and Gary gave me enough knowledge to talk comfortably with contractors.
