5.0 Mary F. Staten Island, NY

Nick was amazing! From the start he demonstrated that he was a professional, courteous, knowledgeable, dependable contractor. He called me and we discussed the problem and scope of the job. We made a mutually agreeable appointment for him to come and inspect the roof and see the issues. Even though the weather was bad he called and showed up at the appointed time. He thoroughly inspected the roof, took photos and videos and then explained to me all that would be needed to repair it. He promised a written quote that evening and sure enough he provided me with one. As it was a fair job proposal I agreed. Nick actually came to the job at least 5 times to inspect it as we were having lots of rain and later snow. He is meticulous and very respectful and mindful of one's property. I cannot say enough good things about this guy. I wish all contractors were this honest, thorough and decent. I recommend him without reservation! Five star all around.

5.0 Biana D. Staten Island, NY

Excellent service at excellent price ! Nick was simply fantastic. He figured out where the leak was immediately where two ( general contractors) tried and failed to locate it. He patched up the leak and now, 3 months later , after multiple heavy rains, no signs of any water getting in,

5.0 Melody A. Staten Island, NY

Nik was great! He did such a thorough job. He even showed me a video when it was done so that I can see all sides of the chimney. I would highly recommend Demar Roofing.

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.
