About Top Star
Meet Kristian Lamthi, owner, foreman, and the guy on your roof
Kristian didn't learn roofing from a textbook. He learned it on ladders, in Calgary winters, through summer hailstorms, and during those weird October chinooks that swing 20°C in an afternoon. After 15+ years of hands-on work across the city, he launched Top Star Roofing Inc. to do things the way he believed they should be done: owner on every job, honest quotes, work that holds up.
The crew at Top Star stays small on purpose. Every person on your roof has worked alongside Kristian, trained to his standards, and earned their spot. You won't see a rotating cast, you'll see the same tight team from the first shingle to the final cleanup.
