Description of Work: On April 6, 2011, Semper West replaced a roof on my Burtonsville, MD town house, with the work coordinated by their great Project Manager, Lance Dodd. (My review of that excellent experience is also posted.) Well, earlier this month, I called Lance, in connection with my roof, and I experienced the same superb service that Lance and Semper West provided last year. On or about March 14, in glancing at my roof, it looked as though a shingle had been lost. (Our area had experienced a couple of weeks of very high winds.) I called Lance, who stopped by my home later the same day. Lance called me and explained that, while he had not been on the roof, he also thought a shingle was missing. He promised to have a crew examine the roof and repair it, if necessary. A package of shingles were delivered to my house the next day. About a day or so later, Lance called me to explain that, when his crew examined my roof, they discovered that, it had not lost a shingle after all. It just so happened that, a stray shingle, presumably from another house, happened to land, upside down, on my roof; and, it had given the appearance of a missing shingle. Lance told me that, I could keep the delivered package of shingles, for any possible future event. And, the company charged me nothing, for this wonderful, follow up service. I regret that, I inconvenienced Lance and Semper West, since my roof did not need repair after all. But, I am very grateful to Lance and the company, for their reliability, and immediate response, to what appeared to be a problem. One cannot ask for better service than that.
