“From quote to cleanup, the Leakproof crew was professional and fast. New roof in two days and not a single nail left in the driveway. Genuinely impressed.”
DMDave & Karen M.London, ON
“Had a bad leak after a windstorm. They came out next morning, found the flashing issue and fixed it on the spot. Fair price, no pressure. Highly recommend.”
