"Really great experience. Flash Roofing worked with our insurance, installed our roof and cleaned everything up in a day. They also came back the next day and installed new gutters. Felipe is great, and he does everything he can to help."

"We interviewed 6 companies recommended by Angi's List and Bone Dry Roofing won out. On time, professional, and great communication. The bid was reasonable and fair. We were able to choose several dates to start the work and the work was complete as described. We also had them touch up the paint on our fascia, during their work day. Overall, very satisfied!"
