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.

There's no question that I would hire Rob Campbell for my next roofing project. Rob and his team provide world-class craftsmanship and customer service. They recently replaced shingles on my shed - on time and at a great price. They take great pride in what they do and pay attention to the details. That makes all the difference!

If I could give him 10 stars I would. Rob is always on top of literally everything with a strong attention to detail. His team is professional, clean and meticulous. We are so happy with the work - our neighbours even comment on it !

Great having the peace of mind Rob gave me, I’m extremely appreciative!!! Thank you Rob and Team!!!

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 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.
There is not much data on Campbell Roofing & Siding. 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.
