Kornerstone Roofing Company is the absolute best. Their eye for precision and detail for our somewhat complicated roof was amazing. They took the time to make a custom drip edge on my barrel roof. They also made improvements with valleys for better run off. They completed the job in one day and left the area as clean as it was before. I would highly recommend them for any of your roofing needs! Their company was one of most professional companies I’ve ever dealt with. Thanks for a great job! Tony D...

I would like to say that this 5 star rating is TRULY well deserved. Michael was the first representative of Kornerstone roofing I met. Michael walked my roof, entered my attic and did a complete inspection. All work quoted by Michael was completed. Jenni in the office kept me informed on deliveries of material and scheduling. Finally I met Sergey, Nick and the crew. I was 100% satisfied with my roof. The crew works hard, they are professional & courteous. My house was completely tarped & protected and the crew was constantly cleaning all day. I'm glad I chose Kornerstone Roofing and would highly recommend. Thank You Kornerstone Roofing for a Great experience. Thank...

I got multiple estimates as one does when needing a roof replacement, everyone said the same thing in their own words - my flat rubber roof (with additions throughout the years) was in rough shape and needed some serious attention. Sergio came out and not only gave us an estimate for the roof replacement but took the time to go over the details, made us feel very comfortable about what was needed, and listened to our concerns and gave very personalized recommendations - including much needed gutters on the back! I was very impressed with the professionalism of the entire crew. They were extremely respectful while being at our house and cleaned up after themselves each day. This was a big project with early start times and they worked into the evening to get it done, and I am very happy with our decision on going with Kornerstone! We also got a “thank you for your business” box of goodies at the end of the job which was a really nice touch. The new roof looks amazing! Family owned and operated local business that will not disappoint. Highly recommend!...

Kornerstone Roofing exceeded all my expectations! From the very beginning, their team was professional, responsive, and easy to work with. They took the time to explain the entire process, helped with material choices, and kept me updated every step of the way. The crew showed up on time, worked efficiently, and left my property spotless when they were done.

The quality of their work is outstanding. my new roof looks amazing and I feel confident knowing it was done right. It’s clear they take pride in what they do and care about their customers. I highly recommend Kornerstone Roofing to anyone looking for honest, reliable, and high-quality roofing work. Definitely a 5-star experience...
