    Doherty Slate Roofing did some slate roof maintenance and replaced a rubber roof over our front door. We felt his team did very good work. They were not the cheapest contractor that I talked with but I felt that they were very experienced and honest about what it would take. The made me feel confident in choosing them and the work they did reinforced this confidence. I would use them again.

    Jason and his team did an excellent job with our slate roof for a very reasonable price. They replaced missing slates, made urgent repairs where needed, and helped us identify future issues before they became a problem. They even cleaned up some of the poor work done by previous roofers. We will definitely use Doherty Slate Roofing to maintain and fix our roof in the future.

Where this page comes from

Every figure above is Google’s, captured on 24 September 2026. The star average and the 57 ratings behind it are counted by Google across all of its reviews. The review text on this page is a sample — we hold 57, of which 52 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.
