Serge was an absolute pleasure to work with , I had a leak in my 4 yr old roof ( unbelievable) I contacted Serge and a day later he was here to investigate the leak , he identified it , gave me the price ( I had other opinions and prices ) he was actually lower than the rest, he scheduled me for a week later , he and his team showed up on time and made the repair and my â leak â a week later was gone after some hard rain , they took pics every step of the way showing me the damage and how the fixed it , they were the best !!!

5.0 Adele C. Clifton Park, NY

Glad I hired Kornerstone Roofing. Very professional and pleasant. Certainly hard workers. Completed repairs in one day under not so favorable weather circumstances. I would hire them again, no problem.

5.0 Bonnie A. Schenectady, NY

I called Serge at Kornerstone Roofing about repair of my roof due to wind blown damage. He arrived at the scheduled time and performed the repair in an efficient and professional manner. I will remember Kornerstone Roofing when it is time to replace my roof.

They were very helpful in other problems that came up. The work and clean up was great and they were very professional and friendly. I would highly recommend them.

5.0 David D. Waterford, NY

Prompt, professional and gave me feed back the entire job. Job became a little more involved and they handled it smoothly. Definitely recommend this company. Contacted them on Wednesday, got quote on Thursday, and following Tuesday did the job. Roof looks great, doesn't leak anymore and they also fixed missing weatherstriping around two windows causing the leak.

HomeAdvisor allows Service Professionals to post information about themselves and their business on their profile. HomeAdvisor does not review or verify the information representations set forth in those profiles as they are self-reported by the Service Professional.

HomeAdvisor verifies state-level licensing where applicable - note: some states require local or county level licensing and you should verify whether or not your pro is properly licensed.

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.
