My house was under contract during the hail storm last May.  Kelly saved the sale of my home by getting the roof replaced right away.  He worked with my insurance company so I could focus on my life, not my claim.  Thanks CIG Construction!!

But at the end of the day, you don’t have to take our word for it— hear it first from our valued residential & commercial clients. 

CIG Construction did a great job on our roof! They worked with our insurance and took care of all the details. We are very happy with the look and quality of our new roof. We highly recommend CIG Construction!
