I had to get a new roof due to wind damage. Grieff’s did an excellent job and cleaned up afterwards. I would highly recommend Grieff’s.

Due to hail damage we had Grieff's install a new roof on our house and garage. They got it all done in 3 days and did a great job. The workers were very efficient and cleaned up around the house very well. I would certainly recommend Cody, Tim and their crew to everyone. Thank you for a job well done.
