I wanted to report the excellent job you did on my roof.  Your crew was energetic, polite, and efficient.  Two days after you installed the wrap your crew came back again to make sure the tarp was well fastened and secured.  The exchange I had with the supervisor of the crew was very cordial yet speedy.  I am very pleased with the work you did.  Keep it up!
Sincerely,
