"We recently had our roof replaced by ODR Roofing, and I couldn’t be happier with the experience. From the start, communication was excellent—Oscar was incredibly helpful and kept us updated at every step of the process. He took the time to explain our options, gave thoughtful recommendations, and made sure we felt confident in our decisions. The entire project was handled quickly and efficiently without compromising on quality. The workmanship was outstanding, and the attention to detail really showed in the final result. What could have been a stressful project turned out to be smooth and worry-free thanks to their professionalism and reliability. I highly recommend ODR Roofing for anyone looking for a seamless, high-quality roof replacement with top-notch customer service."

"Sam was exceptional and very thoughtful as a project manager. He was very caring and honest and took care of some repairs on the roof himself. He walked us through the process, and made sure we were aware of everything going on. I reccomend Platinum Roofing and Retrofit to everyone who wants honest and quality work! Thank you guys!"
