Based on reviews across multiple platforms—including Google and trade directories—customers generally give J&C Roofing (often listed as J&C Roofing Ltd or J&C Roofing Specialists) highly positive feedback, averaging an impressive 4.9 out of 5 stars.  

The consensus from local London and Greater London clients highlights several key trends in their service:

The Positives

Quality Workmanship & Reliability: Homeowners frequently praise the team's technical skills, particularly when handling new roof installations (such as slate or plain tile), porch roofs, and roof line updates (gutters, fascias, and soffits).  

Professional Conduct: Customers often call out team members by name (Carlos is frequently highlighted in reviews) for being exceptionally polite, pleasant, and professional to deal with from the initial quote to the final clean-up.  

Effective Leak Resolution: Many 5-star reviews come from highly relieved homeowners who had been suffering from multiple leaks due to aged roofs or slipped tiles. They report that J&C diagnosed the issue accurately and permanently solved the problem.  

Competitive & Honest Pricing: Reviewers note that the company provides fair, transparent, and highly competitive quotes compared to other local outfits, with no hidden extra fees tacked on at the end.
