- "I just had a roofing job completed by Cornerstone and couldn't be more satisfied! The crew was excellent and we fell in love with them in the few days they were at our home. The roof was a 12/12 pitch and two stories and they had no issues with removing the old and installing the new Certainteed dimensional shingles. The job site was left as clean as if they were never there. We were pleased with the sales staff and doing whatever they could to make us happy. I have never wrote a review but in this case I can't help but give them my highest recommendation. Ask for Mariana's crew and salesman Kevin Pack!"
