Was nearly involved in a motor vehicle accident because one of their drivers cut us off, if they can’t see a massive white truck don’t expect them to get every detail of your roof.

Where this page comes from
Every figure above is Google’s, captured on 24 September 2026. The star average and the 6 ratings behind it are counted by Google across all of its reviews. The review text on this page is a sample — we hold 6, of which 6 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 John Martin roofing and renovations. 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.
