William Ward, a roofer employed by Guyou Construction, responded out to our house on 1/20/2023, to check on a roof leak after we had some solar installed by another company. He had to replace ten tiles that had been broken by the other company’s installers and they had tried to glue them back together. They never bothered to tell us of course.. William did this in the rain no less. Of course that is a issue with the unnamed company. William was nothing but courteous, professional and informative. We highly recommend him. A nice guy.
