Lifetime did a good job with my roof replacement and solar installation. It was convenient that they did all the coordination and it was all with one company. They worked with my insurance company directly, which made it easy on me. We did have an issue with one item, but I reached out to Max who was my sales rep, and he helped fix the issue and get resolution. Overall, it was a very easy process with Lifetime Roof & Solar.

JB and Eduardo at Lifetime Windows were a great team. My new windows are great. The team did a great job installing my windows and cleaning up. I found some damage afterwards which I had to take care of and then get reimbursed by Lifetime. It took awhile to get reimbursed but they did send me a check for the damage.
