Dear Mr. Gates:

I have been meaning to get this letter of thanks to you for quite some time and my hectic schedule keeps getting in the way. This past fall your firm put a new roof on my house and I want you to know how pleased I am. The workers were very cooperative, professional and clearly knew what they were doing. The quality of the work was great and the cleanup after the job was complete was excellent. I am very happy with your firm. As you know I have used your roofing company in the past and the reason I used your services again is the quality of the work performed. When I find a good company, I stay with that company.

Bottom line is that I would not hesitate to recommend your roofing company to others in need of work. Thanks again.

Alan M
