The first three are Google’s own figures for Blackstone Roofing, read on 24 September 2026; the share is of every rating Google has counted, not of the review texts on this page. The median is ours — the middle figure among the California roofers we list with enough ratings to compare.

Too few ratings to compare against other roofers — at 4 ratings a single unhappy customer moves this figure by several points.
The critical reviews
The one and two-star reviews, first. These are what a star average hides, and they are the reason this page exists.
We hold no one or two-star review text for Blackstone Roofing. That is not the same as there being none — it means our capture did not reach any. The rating breakdown above is Google’s own count and is the number to go on.
What reviewers keep mentioning
Topics Google extracted from this business’s reviews, with how many mention each. These are words that appeared in reviews, which is not the same as a service the business sells.

Other reviews we hold
4 more of the 4 reviews we hold text for, most recent first. We do not hold every review Google has.

Blackstone Roofing found the source of our roof leak and showed us pictures of the damaged area. The repair was done quickly and everything was cleaned up afterward.

I would give them 10 stars if I could. These guys are fantastic. they did a replacement for my plaza 2 years ago, good price, easy communication and got the job done professionally. It has been 2 years from the replacement, and I got 0 problem with it, so I got to come back and give them a 5 stars.

Thank you so much, it was our pleasure to work with you.
What Blackstone Roofing says about itself
Taken from the business’s own website. We have not checked any of it. These are quotes, not credentials — a roofer writing “licensed and insured” on their homepage is not evidence that they are.

Where this page comes from
Every figure above is Google’s, captured on 24 September 2026. The star average and the 4 ratings behind it are counted by Google across all of its reviews. The review text on this page is a sample — we hold 4, of which 4 have any text — and it is not everything Google shows.
Roof Warden does not verify licenses, bonds, insurance or workers’ compensation cover, and nothing on this page should be read as though we had. Confirm those directly with the contractor and with your state or provincial licensing body before you hire anyone.
There is not much data on Blackstone Roofing. A short record here means our capture found little — not that there is nothing to find, and not that the business is new or inactive.
