Read all our reviews"After two ice dam disasters with our old shingles, we finally went with metal. Three winters later, not a single issue. The crew was professional and finished ahead of schedule. Best investment we've made in this house."
Michael R. · North York
"Our 1920s house had a 5'6" basement — basically storage. Now it's 8 feet with a legal apartment. The rental income covers a big chunk of our mortgage. Should have done it years ago."
David & Lisa T. · Toronto
"The builder left us with grass and two sad shrubs. Now we have a patio, fire pit, and the kids have their own zone. It finally feels like our home."
