A.D. Roofing was recommended by our neighbor who had their roof done the previous year. We had noticed how organized Alex and his team were on our neighbor’s roof project and decided to get a quote. We gathered a couple of more bids for comparison, but Alex’s quote was the best. Since he was both knowledgeable and reasonable we decided to work with him.
We are so happy with the end result of our roof project!! Alex and Alex Jr. both provided us with exceptional service and answered all of the questions that my meticulous husband asked. My husband has great attention to detail and assesses a company’s / person’s commitment on the initial contact. He was impressed with Alex and Alex Jr. and sensed that they both cared about the integrity of the job and what the customer wanted the results to look like.
I believe we were fortunate to have Alex and his team on our roof project. His trustworthy crew was timely, well organized in their tasks, and cleaned up the work area before they left each day.
We have had many complements from our neighbors and will be happy to pass on our support for A.D. Roofing! Thank you Alex!
