Customer Quotes
Of the four estimates we had for a re-roofing job, Cornerstone Roofing’s was the most inclusive with all details needed to create a new roof and at a competitive price. Within ten minutes of the roofing completion three neighbors individually walked over to compliment the appearance and the professional manner demonstrated by all the workers. Cornerstone Roofing employees were very capable, hard working, and considerate. We are most grateful for a job well done, one that we gives us pride in our home ownership.
