4.0 Gerald S. Oceanside, CA

When I originally requested an estimate their scheduler called right away and their foreman was out the next day to give me an estimate . I set up a tentative date to get the work done. That date came and went with no communication. it took several more days before I was able to get through to their scheduler to set up a work date. The foreman and his crew were here on the scheduled day, they were courteous and professional and knew exactly what to do and got My roof repaired on time. I am very happy with their work. not counting the office communication, I would hire them again.

4.5 Jeff C. Valley Center, CA

No one looks forward to roof repairs... Sergio quoted the job and displayed great knowledge and even pointed out some things that needed to be corrected. I had a bad leak and he even provided a temporary fix that stopped the leak. Quote was a little above others but felt they were competent and knowledgeable. Started work next day, ahead of storm and Sergio spent time on jobsite making sure everything was going OK. Would recommend.

5.0 Pat C. Vista, CA

Sergio was so helpful explaining the reason for my roof leak. Also gave me a temporary fix ahead of tomorrow's storm. Very kind and helpful. Thank you Sergio for calming my worries about my roof. I know work needs to be done but I'll be ok for tomorrow's storm.

4.5 Antonio C. San Diego, CA

Very fast, no communication issues, friendly. They have the "get the job done" attitude. -- Job was started and finished without making any type of excuses or extra fees.

Seal of Approval

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)
    We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.
