Nearly all reviewers across multiple years praise Rainbow Steel for fast, professional metal roof and gutter work done to spec. Jasmine handles quotes and follow-up with quick replies; crews finish jobs in one to three days, use better materials than competitors, clean up thoroughly, and honor the 50-year metal roof warranty claim.

Esteem Roofing

4.6(14)✓ Google-verified

Reviewers consistently praise Esteem Roofing for honest pricing, skilled crews, and strong follow-through on roofing and gutter work. Sukhpreet Singh leads the team with a reputation for problem-solving, especially diagnosing tricky leaks and condensation issues. One complaint flags that the company does not always respond to emergency calls when at capacity, which matters if immediate availability is essential. The business works directly with insurance claims and handles roofing, gutters, siding, soffits, and fascia. Customers emphasize keeping their word and delivering without supervision needed. Turnover in pricing versus other quotes is a recurring strength.
