The first three are Google’s own figures for On Top Roofing, 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.

Too few ratings to compare against other roofers — at 5 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 On Top 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.
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.

What a great experience working with Solivan! Only 5 days from meeting for a consultation, to receiving a quote then job completed! Thank you so much, will be recommending you to everyone I know.

Solivans has completed several jobs on my home including roof venting, eaves trough and roof replacement. All jobs were done with great care and professionalism. Each job completed was followed up after to ensure satisfaction and long term workmanship. Great work.

Solivan showed up the same day after I called that I had significant damage to my roof from a wind storm. Problem solved. Years ago he did both my shop and house and they have stood the test of time. Best quality for sure!

Solivan did a great job with both my roofing and my eaves trough. He is reliable, prices fairly and the quality of his work is excellent. I recommend his company highly!

Soli did a careful and meticulous job of installing facia,soffit and eavestrough. He was available for communication which is important to me.

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 5 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 On Top 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.
