The first three are Google’s own figures for Alpha Demolition, 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 Alpha Demolition. 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.
Other reviews we hold
3 more of the 3 reviews we hold text for, most recent first. We do not hold every review Google has.

We have been working with Alpha Demo for 9yrs, they have always provided professional roof demo services for us ranging from small carports to entire HOA complexes. No job is ever too small or too big for this family owned business, they are always up for the challenge. Their pricing has always been very reasonable for the quality of work they provide. We would 100% recommend Alpha Demo, keep up the great work guys!

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 3 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 Alpha Demolition. 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.
