Dawson and son provided excellent service and were willing to offer a less expensive repair than any other company …and their solution was very effective. Very honest company, service was thorough , minimal waiting time and great clean up. Highly recommended ! We had them for eavestrough work.

A couple of sheets of shingle blew off the roof in high wind. Who could I get for a relatively small but urgent job. Contacted Mike Dawson - he came by to inspect the next day, and did the repair 2 days later. Straight up, professional, quality job, economical. Doesn't get any better.

Where this page comes from
Every figure above is Google’s, captured on 24 September 2026. The star average and the 32 ratings behind it are counted by Google across all of its reviews. The review text on this page is a sample — we hold 32, of which 29 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.
