The first three are Google’s own figures for Alliance Roofing Ltd, 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 Ontario roofers we list with enough ratings to compare.

Much higher than most — the typical roofer in Ontario sits at 2.9%. A higher share is a reason to read the critical reviews below, not a verdict.
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 Alliance Roofing Ltd. 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.

We had a bit of an emergency as a piece of aluminum siding came down off of our home the other day(not Alliance’s work, it was the original stuff to our home). Alliance was the first company I called because honestly I have never dealt with this before and I figured at the very least they would refer me to someone like a handyman or something who would handle our type of siding/help. Office calls me within 15 minutes of me leaving a message and asks for photos so they could know what equipment to bring. I could have cried. Jann gets my info and they send me a quote for the work. I am in full communication with him the whole time. They send out Travis the next day at 8 AM. He arrived on time, I showed him the spot (and then a couple other concerning spots) and he reassured me and gets to work! Job is done after not long, our home is fixed, and as Travis leaves the invoice is emailed to me. I paid it within 10 minutes of receiving it. Gold star customer service from Jann at the office/dispatch and Travis who came out to help. Gold star billing (I mean really, comprehensive invoice and super easy to pay). I don’t know what I would have done without them honestly. You’re not always taught who to call for these sorts of things, so I turned to Google for a local company and crossed my fingers they got in touch. Thank you Alliance for looking out for us!

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 16 ratings behind it are counted by Google across all of its reviews. The review text on this page is a sample — we hold 16, 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.
