Customer Reviews
JP Charfauros
We needed a new roof and a friend recommended Semper Solaris. Phil came to our home and did a thorough inspection, and we decided to move forward. He was very helpful and patient through the initial phases of the project. We had some leaking, so the team graciously installed a secure tarp on both our roof and chimney while we waited for the repairs. The team at Semper communicated clearly throughout the process of removing our solar and replacing the underlayment on our roof. They handled the permits for us as well. Christian and his team worked very hard and sent daily photo updates which was much appreciated. They also cleaned up thoroughly at the end of each workday. Now we are just waiting for the solar reinstall. We are thankful for a job well done!

Ken Hartman has been wonderful to work with. From explaining the process, to taking window measurements, he never left me out of the process. When I have had questions, he immediately called me back when I left a message. I have enjoyed working with you Ken and will ensure you are the first I call when I am ready to replace my sliders. Thanks!
