Brad is usually with a customer, on a roof, or in an attic. His goal is to provide professional roofing services at reasonable prices. Ask Brad if Weatherproofing might be an option for your roof to extend its life.

Brad is pleased to announce that their exclusive Weatherproofing shingle protectant, Dr. Shields Canadian Roof Armor, will be seeing many more moons, now doubling from an original 5-year to a 10-year Weatherproofing warranty, after exceeding original expectations.

Bob uses his background in engineering sales and computer programming to offer detailed sales and application support.

Bob joined The Great Canadian Roof Doctor Inc. to help introduce the life extending roof Weatherproofing (sealing) option, because it makes sense.

Bob's written a 6 page technical roofing article as well as a few other articles to share with others the great news about how to extend the life of asphalt shingle roofing material. Bob enjoys responding to customer questions, and does group presentations without a script. He's even shingled his own garage roof, but now prefers to keep his feet on the ground.
