“Gary,

Thanks for the honest, thorough, informative and exceptional work while replacing our roof. I know that you found some surprises, and we had to review the options. The process with you was as painless as could be expected. Thanks for the up-front list of items and the contract which was followed to the letter. 
 
It was very surprising and pleasant to get frequent updates from regarding expected arrival times & changes to the schedule due to the weather, which was definitely making your job harder.
 
I have already recommended you to a neighbor, Kevin Parsons, who is considering having his windows replaced.
 
I will keep you in mind should I have another big project, and recommend you again to others.
 
Take care & thanks,
Ben Dibble”
