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 Bismark 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.

We have a 1921 Chicago Bungalow with a red French Tile roof that is over 100 years old (well, parts of it are - and parts or much newer). We've used Bismark Roofing for minor repairs and work on it and have been very satisfied with their price and workmanship. We also used them to re-roof our garage and to make some repairs to the fascia of our roof dormers where the tiles overhang. We are also very satisfied with that work. I definitely recommend, especially if you have a tile roof, which I understand Ross Bismark really likes to work on.

Where this page comes from
Every figure above is Google’s, captured on 24 September 2026. The star average and the 3 ratings behind it are counted by Google across all of its reviews. The review text on this page is a sample — we hold 3, 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 Bismark 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.
