Public Records Check

  • Missing License Our automated search didn't find a license on file for Reliance Roofing with the California state licensing board. That doesn't mean the company is unlicensed. A license can be held under a different business name, registered too recently for us to match, or filed in a way our search didn't catch. We recommend confirming directly with the California state licensing board or asking the contractor for their license number.
  • Registered Corporation Reliance Roofing's registered name carries a corporate suffix (LLC or Inc), but we have not matched it to a filing on the California Secretary of State. You can confirm how the business is registered, and its current status, directly with the California Secretary of State.
  • Unverified Address Reliance Roofing's listed address at 9431 Haven Ave Ste 232, Rancho Cucamonga, CA 91730 appears to be a unconfirmed 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.
  • 2 Credentials Reliance Roofing holds these manufacturer certifications: CertainTeed ShingleMaster, Owens Corning Preferred. These show the company met a manufacturer's program requirements and may offer manufacturer-backed warranties, but they aren't independent quality audits. You can confirm current status with the manufacturer.
  • Excellent Ratings Across the platforms we identified for Reliance Roofing (Google, Yelp, the Better Business Bureau), the blended average is 4.5 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.

We verified 3/5 public records for Reliance Roofing. The more of a company's record you can check, the more informed your hiring decision.

About this review summary

This summary was automatically generated from customer reviews that were publicly visible at the time it was created on one or more of the review aggregators listed below. It does not constitute a review, rating, endorsement, or statement of fact about the business - it reflects only the opinions expressed by those reviewers as found at that time, not the views or conclusions of RooferWatch. Automated summaries can contain errors or omit context and may become outdated as new reviews are posted, so please read the original reviews through the links provided and do your own due diligence. If you are the business owner and believe anything here is inaccurate, submit a correction and we’ll review it promptly.
  • Avg. Rating 4.5
  • BBB A+
  • Google 4.8
  • Yelp 3.6

Reviewers report mixed experiences with this roofing company. Several customers describe significant scheduling and communication problems, including multiple no-shows, late arrivals, and difficulty reaching staff. Some reviewers experienced issues with work quality and warranty fulfillment - one customer reports an unrepaired leak that persisted beyond the warranty period, while another describes defective workmanship on a roof replacement that eventually led to insurance involvement and a full refund. Communication challenges are frequently mentioned, with reviewers noting they had to chase the company for updates and answers. However, some customers report positive experiences, praising specific staff members for reliability, responsiveness, and quality work. One reviewer describes an estimator's unprofessional behavior during an inspection. Another customer reports the company refused to provide a quote after an initial assessment.

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, Yelp, 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.

These figures are derived from this company’s 30 most recent publicly visible Google reviews at the time they were gathered. They simply describe patterns in those reviews - how often new reviews appear, how often the owner replies, and whether recent star ratings run higher or lower than older ones. They are not a review, rating, endorsement, or judgement by RooferWatch, and they reflect only what those public reviews showed at that time, which can change as new reviews are posted. Please read the underlying reviews and do your own due diligence. If you are the business owner and believe anything here is inaccurate, submit a correction and we’ll review it promptly.
