After our hail damage destroyed our roof we were recommended for Lifetime Roof and Solar to come out and inspect the damage. Jim Salmon was great, he came out and inspected the roof and was willing to work with us with any questions or concerns we had. They came out with in the week and installed our beautiful brand new roof quickly. Thanks again for great service!

Woody and Jeff coordinated the replacement of our roof after a bad hail storm. The problem for me was a time constraint. They not only beat but exceeded my expectation for workmanship and the pressing deadline I was under. I would highly recommend these folks.
