  • 5★★★★★ - "This company is great. I have nothing but great things to say. Everything turned out wonderful. The quality of their work is 100%. They even redid a couple of things on their own cause they felt it wasn't 100%. They constantly kept me updated of the progress on a weekly basis with a phone call. They are very easy to work with. They also worked with my insurance company for me, saved me the time and got me what I needed. I found them because I saw a bunch of their signs in my neighborhood for other houses that they were working on. They were very popular in our neighborhood and did a great job on everyone's houses."

  • 5★★★★★ - "I can't speak highly enough about Serenity and their employees! They are very professional, always return your calls if they can't answer. No matter how many times you may ask the same question Nicholas was always so nice! Shawn came out to our house, about 1 1/2 hr drive, to bring us 2 samples we wanted to see, now that's service!! Nick was here when the insurance adjuster came, that made us feel better because this is the first time we've ever filed a claim. He would explain everything, in layman's terms, so we could understand. The group that did the roofing were awesome!! They came at 7am, didn't leave until 7pm, they were singing and laughing, you could tell they really enjoyed what they were doing, and they were doing it very good! After their first long day they came the next morning at 7am, worked through lunch, they were singing and laughing this day also, even though they had a late day here the day before! They were done with the roof, cleaned up very good, and were on their way by 4pm!! JOB VERY WELL DONE!!! I would highly recommend them, and I have!! Thank all of you so MUCH!"

  • 5★★★★★ - "I took it as a sign from God that I needed a new roof when several shingles fell off my 20+ year- old roof. Serenity Concepts came out within three days to give me a very reasonable quote for the cost of the new roof. Between the initial quote and when the work started, I received weekly phone updates, letting me know when the work would begin. In addition, the owner stopped by the work site several times during the installation to ensure the work was being completed and communicate with me. The owner and his roofing crew found several problem areas on the roof and fixed them without an additional cost to my original quote. The work crew was friendly but professional and did an excellent clean up job. I could not be more pleased and would highly recommend this company to anyone in need of roofing, siding or other exterior home repairs!"
