"We hired Cox to repair/replace the both sides of the church's pitch roof at Our Lady of Hope Church in Dundalk. They took off the old roof, added plywood, new cloth and shingles. We are talking about a roof that is 1000's of square feet! The job was done within the allotted time. The clean-up was superb! The price was 17% below the closest bid price. A most excellent result from a fantastic company."

"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"

"Sales agent was VERY thorough in explanation of roofing materials and venting system, installation and warranties for the product. He did a complete inspection of roof, inside attic and outside. The receptionist was also very responsive in setting up the appointments for roof an gutter installation. Roof looks great!"

"From the 1st meeting with the 1st PHR's representative, I was sold. I was so impressed with everyone's kindness and professionalism, making me feel very secure. Our coordinator showed us a few videos of the process. Every question we had, he answered without hesitation and he provided samples as proof. We signed that day and within one week, we had a beautiful new roof with an even more wonderful guarantee. The crew arrived on time, they were all courteous, kind and clean. The entire project took one day. I was contacted by several people during the course of the day and after, in person and by phone, to make sure everything was going well, then after the crew manager walked me around the house to make sure I was happy. The perimeter of my house looked as though the guys vacuumed my lawn it was so clean, better than before they start. We are both so happy with our new roof and our entire experience, we will definitely use PHR for our next project... siding."

"It went extremely well. Excellent customer service and quality work at a fair price. So happy to find a good, reliable company that truly cares and respects the clients they service. I dread the day when I'm going to need a new roof. However, I'm happy to know that Mike and his team will be there to service me."
