Professional work. Brought their own dumpster and restroom to minimize contact during Covid. I worked with Don and Jeff who were both professional and helpful! Roof workers were also professional. They cleaned up each night. Specifically, they went around the house cleaning up all the little nails, which is very appreciated with young children.

I was a little hesitant, but after talking with one of their reps think his name was Tommy, put me at ease. Looking forward to getting some sweet new windows. Our energy bill has been out of control hoping this will improve the efficiency, will get back to you!

Don & Jeff used their professional knowledge to resolve the push-back from the insurance company. Then, they and their team came in and completed the job in one day. My roof looks fantastic. I will definitely use Lifetime Roof & Solar again.
