Last fall we hired Cobex for roof replacement after a leak. They were efficient and did a great job

I live in a home owners association. One of the roofers got a speeding ticket. The project manager said the Company would pay the fine. A month and two emails later radio silence and no effort to pay the fine. Can't judge the workmanship since it hasn't rained enough to test the roof. However, given the companies failure to live up to the representation of the project manager and their failure to respond to my emails over such a simple issue, I anticipate problems will be forthcoming.

Cobex did a great job replacing my old roof from the initial call to final cleanup. They were very responsive in getting all of the details right Ahead of time, and were prepared for every question.

I regret hiring Cobex to install a new roof on my house. They took five months to begin work and took twice as long as expected to complete. We asked the sales crew for custom skylights and to repair dry rot on the architectural details of the house. None of these details were passed to the construction crew and during construction, we were told the custom skylights would not be covered under warranty. It also became apparent that they did not have the expertise to handle the carpentry work for the dry rot repair. I had to manage the project daily to direct the repair work and point out corrections. In the end, we didn't get the skylights we agreed to and the dry rot repair and detail work was subpar. They missed areas of dry rot and used inferior wood. Also, Cobex did not tarp the roof before a predicted rain storm and damage was done to the interior ceiling, walls, furniture and carpet. Five other homes they were working on were also affected. I hired another contractor and did work myself to make repairs they missed since I did not trust Cobex's workmanship. We were given a discount but that did not cover the cost of additional repairs and rainwater damage.

Wow! I can't thank David Leal enough for helping me get a new roof and some windows. The guys he had working here were the best. Cobex and David have restored my faith in the construction industry. Thank you!

Well, my review if preliminary because we are waiting for permits and for the rain to stop but up to this point everyone has been very friendly and professional! Trying to keep me up to date on everything. I will update this as we proceed!

This company hires sub-contractors for their work and the quality of their work is poor. The gutter screens weren't installed correctly by the sub-contractors so they had to take everything off and re-attach them. Gutter connector broke so rain water was running off the side of the house so they came out to fix that. I would never hire this company for any work anymore.

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.
  5. Sex Offender Search
    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.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
