The first three are Google’s own figures for Diamond Roofing Systems, 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 Ohio roofers we list with enough ratings to compare.

What Diamond Roofing Systems 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 5 ratings behind it are counted by Google across all of its reviews. The review text on this page is a sample — we hold 5, 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 Diamond Roofing Systems. 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.
