"Very pleased with the roofing and siding work performed by ROI Construction. Jose was especially helpful and very knowledgeable in all areas of home repair, including roofing, skylights, trim and siding. Brooke did a great job scheduling and managing the project. Highly recommend ROI for your roofing/remodeling needs."

"Initial rep was great and informative. Felt comfortable with initial sale. Hardly had any contact from customer service except for the payments. There were several delays that we were not informed about unless we called to ask. Took 7 months before they showed up to begin project. Only 1 person was sent to build steps. Took a week. Hard worked, hardly took a break. Had to call again to see when they would come to pour patio. Never knew when they were coming, they just showed up. Hardly spoke with the homeowners. Inspection paperwork was just left on porch. Additional paperwork that is "required by the County" had to be completed by homeowner and taken to Court house to be notarized and filed and also provide a copy back to Long Fence. Time sensitive materials which added to homeowners to-do list. Gave this contract to LF on the surface of their history and appearance of a 'good local company' but should have stayed with original contactors in VA. Puddle of water forms when it rains"

"Reese guided us through the many possible flooring solutions and helped us to select appropriate choices based on our specific needs for the three rooms involved. He lent us the large-size samples to bring home to do color matching. He then came over to measure exactly, specify, and propose the specs and costs. Upon acceptance he ordered the materials and scheduled the work. The two specialists came on time and did excellent, professional work (10/31/19 - 11/1/19). We've given it 7 weeks before writing the review, during which we are enjoying the new flooring more and more, and are glad we did this long-needed upgrade. No problems arose during this whole process and Reese and his workmen patiently and expertly answered our many questions throughout."

"I felt like I was really pressured to make a decision right there and then -- and I was clearly uncomfortable with making this decision. After sleeping on it, I decided this was not the right time to get luxury vinyl plank for so much $ and canceled the order. I have yet to receive the refund which was for 50% of the total price."
