"Certified roofing did very well. They were the first to respond to my Angi query. Tim was smart, quick, and had an excellent work ethic. We had a slight miscommunication on what the job entailed, which is being cleared up as we speak. I would definitely hire them again."

"Since my roof is 20+ years old, I have a Home Confidence Plan with Arocon, which includes two roof inspections (tune-ups) per year. Preston and Keith were the technicians that performed this service on July 27, 2022. I can only say positive things about these technicians. They were very thorough, making some minor repairs (exposed nails). They took photos of the roof, which I received via email soon after the visit. Preston is very professional and knowledgeable, and clearly explained what the issues are with my roof and its overall condition. I have had this service with Arocon for a couple of years and I derive much peace of mind in maintaining my roof with Arocon until I replace it. Based on my experience with Arocon, I will be very inclined to hire this company to replace my existing roof when the time comes. Susie Setser"
