    I contacted multiple over 6 companies to get quotes on repairing a leak on the flat roof on my home. Azariel was one of the first to respond, and by far the most professional. He did a thorough inspection and found other issues that could have led to even worse roof issues down the road. He submitted a detailed proposal in a timely manner and asked a reasonable fee. On the day of the work, his team that showed up with him was on time and also very professional. Day of, they found more issues once the flashing was removed, which they were able to resolve and still finish the job that day. The quality of work is great, and you can tell that Azariel and team take pride in their work and really care about a quality product.

    Azariel submitted very detailed drawing of proposed work. Job was finished in just one day. Price was reasonable. No rain yet to get to know if it was successful.

    5.0 Harrison H. Downers Grove, IL

    Prompt responses, very professional, repairs finished in one day in spite of having to work around unseasonable weather. Great clean up, would highly recommend this company.

    5.0 Charlie R. Lombard, IL

    Azariel Coss and his crew did an outstanding job, very professional and detail oriented. I would highly recommend him if anyone needs a new flat roof or just repairs. After finishing the project, the clean up was immaculate. He also sent pictures of the project for our records.

    5.0 Mark K. Lombard, IL

    Extensive photo documentation before and after was really helpful.

    What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

    1. Verify Trade License
      HomeAdvisor checks to see if the business carries the appropriate state-level license.
    2. Verify Insurance
      As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
    3. Verification of State Business Filings
      For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
    4. Criminal Records Search
      HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.

      We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
