Be it from rain, snow, or sleet, your roof can be protected, and a protected roof means a protected home. Simply call us and schedule a estimate today!

    A-1 Contractors are the real deal! Danny and his crew made my roof replacement project a breeze. On time every morning, 7:15am. Every person that I dealt … More with, Danny, Amber, Sarah and everyone on the crew was polite, efficient and knowledgeable. They cleaned up at the end of every day and were attentive to the adjacent property owners as well.
    I own a 100+ year old commercial building. I'm grateful for Danny and his crew's knowledge and experience. Also, Danny was able to reach out to his dad for his experience to address our unique roof.
    A-1 Contractors went above and beyond to ensure that our roofing project was completed in a timely manner and done right!
    I highly recommend A-1 Contractors for your roofing needs.

    This company was so great to work with! Every single person involved in the project conducted themselves in a professional and friendly manner.
    From the
    … More initial conversation to the completion of the project, everything was handled beyond my expectations.
    They were quick, communicative and respectful. We are impressed by how our project was handled and thrilled with the results.
    Our roof looks great!!
    I would recommend this company to anyone and can’t say enough good things! A few points that stood out to me the most:
    - I knew I wanted to do business with A-1 Contractors Inc. immediately after reading through the first page of their bid. It was thorough, informative, and gave me confidence in their abilities.
    - I was also impressed with their punctuality on the job site. The crew had arrived on time and within 5-10 minutes of their arrival our old roof was being taken off.
    - Every single crew member addressed us as “Sir” and/or “Ma’am” and had a smile on their face the entire time. It was very apparent that they liked each other and their job. There was a sense of pride amongst their team and it showed in their work.
    - Finally, our roof was completed in 2 days and our yard was left cleaner than when they arrived!! I couldn’t be more impressed.

    They are amazing! My mother needed a last minute replacement on her roof for the sale of the house. Within 24 hours they had the estimate back to us and … More the job scheduled. They did everything they had to so they could squeeze us in last minute. They job was done within two days! We have had roofs replaced before and usually find nails and wood all over the yard after. I couldnt believe how clean the yard was after! They really came through for us in a critical moment. We appreciate them and their professionalism so much!
