"I honestly couldn’t be happier with Eddie’s performance and the overall experience. Before contacting him, I called three other roofing companies and none of them came close to the value Eddie provided. He offered me the most affordable and fair price without cutting corners, and from start to finish everything was handled in an extremely professional manner. Eddie was outstanding to work with, he was knowledgeable, honest, and very detail oriented. What really stood out was his communication. He stayed in constant contact with me throughout the entire process, keeping me updated every step of the way and making sure all my questions and concerns were addressed promptly. There were no surprises, no delays, and no stress. the quality of the work exceeded my expectations. It’s clear that Eddie takes pride in his work and truly cares about his customers. If you have any roofing needs contact Atom Builders. You won’t be disappointed. 10/10."
