Review by in Groton, CT
I was very pleased with this company's performance from start to finish. They returned my initial call quickly and came out the same day to look at the roof. I was then given a reasonable quote for a new roof with what that entailed written out very clearly. The work was done in two days and the crew showed up at 7:30 and were working in earnest by 8 AM and stopped at 4:30. They were extremely organized, hard working and pleasant guys to deal with. They also did an AMAZING job in cleaning up after themselves. I never found so much as a nail on the ground and no shrubs or damage was done to the house, which was pretty impressive. I would recommend this company highly to anyone looking for a quality roofer.

David and his assistant Scot came at the house to fix the water leak Inside the house near the bay window. He responded very promptly. He was very professional, responsible and courteous. It rained the other day and there is no leak any more. Nice job. I will recommend him to anyone.

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.

NOTE: Member service professional information confirmed as described above may change or expire over time; while HomeAdvisor attempts to maintain accurate and up-to-date information, and confirms changes when notified, we cannot guarantee that profile and screening information is accurate. Therefore, we recommend that before working with a service professional you verify that information presented is still current and/or acceptable to you.
