    We had our roof replaced recently by A-1 Contractors. At 7:30 am, a crew of about 15 roofers were at our home, and immediately began the setup and remove … More the existing shingles. They had 11 men on the roof all day operating in a most synchronized manner, everyone knowing their job and getting with it. The roof was replaced that day and after a thorough cleanup, they were finished at 5:15 pm. The new roof looks great and the efficiency of the operation was amazing. Very pleased with the roof, the workmanship and our overall experience with Danny and Joe's team.Service: Roof installation

    The Team at A1 contractors are top notch. I was looking for something for home and Danny went out of his way to make sure I got what I needed. He was very … More busy at the time and took time out of his schedule to assist me. From his secretary, the driver that dropped off the product nothing but professionalism. Thanks again Danny.

    These guys are great! They successfully guided me through the insurance claim process (when other companies told me I was wasting my time.) Then they saved … More the day even before they put on the new roof by fixing a leak that was suddenly discovered - working during a rainstorm. Finally, they installed a high quality and beautiful roof quickly and on time. Then I found out at the end of the job that they’re a local family business that’s been in the roofing trade for three generations. I’m really happy I hired these guys and highly recommend them.Services: Roof repair, Roof installation, Roof inspection, Roof repair for storm & wind damage
