"This was the second time we hired ROI Construction LLC to work on our home and they did an excellent job both times. Originally our roof was replaced and ROI did a fantastic job, going above and beyond in making sure every detail was perfect. Recently we had the roof and skylights of an addition replaced. In both instances ROI charged less than the competitors and the workmanship was high grade. I highly recommend this company."
