Public Records Check

  • License Found We found a license number on file for CJ Roofing: 420221000021, but haven't confirmed its current status directly with the District of Columbia state licensing board. We recommend verifying it's active and in good standing with the District of Columbia state licensing board before hiring.
  • Registered Corporation CJ Roofing's registered name carries a corporate suffix (LLC or Inc), but we have not matched it to a filing on the District of Columbia Secretary of State. You can confirm how the business is registered, and its current status, directly with the District of Columbia Secretary of State.
  • Mailbox (CMRA) CJ Roofing's listed address at 1835 7th St NW #Ste 250, Washington, DC 20001 appears to be a mailbox (CMRA) address. A roofer using a mailbox isn't necessarily a problem, but it can make the company harder to reach or hold accountable. To reach them in person, ask the contractor for a physical address or confirm one directly.
  • 0 Credentials Our automated search didn't find a manufacturer certification for CJ Roofing. Many reputable roofers aren't certified by any manufacturer, often by choice, so this isn't a sign of a problem. If a manufacturer-backed warranty matters to you, ask the contractor which certifications they carry.
  • Excellent Ratings Across the platforms we identified for CJ Roofing (Google, the Better Business Bureau), the blended average is 5.0 out of 5, which we label Excellent. This is a plain average of public customer ratings, not a RooferWatch score. A high average reflects past customers' experiences, not a guarantee of yours, so read the underlying reviews and weigh them yourself.

Automated summaries can contain errors or omit context and may become outdated as new reviews are posted, so please read the original reviews through the links provided and do your own due diligence.

About this average rating

This figure is a straightforward average of the public ratings we’ve gathered for this company across the following review platforms that our systems have identified: Google, the Better Business Bureau. It is not a proprietary RooferWatch score or a judgement of our own; each source is converted to a common five-star scale and blended into a single number so that no one platform’s reviews carry outsized weight, giving a more balanced read on overall sentiment. We’d still encourage you to read the underlying reviews on each platform and weigh them for yourself.
