Why Kristian Started Top Star

Built to fix what was broken about Calgary roofing

Kristian Lamthi founded Top Star Roofing to fix what he kept seeing in Calgary's roofing industry, large companies winning jobs on slick sales pitches, then handing the actual work to whatever subcontractor was cheapest that week.

Homeowners paid premium prices and got crews who'd never spoken to the company that sold them the job. The quality showed it. The warranties were worth less. The follow-up calls went unreturned.

Top Star runs differently. Kristian, his brother, and the family crew handle every roof from the first inspection to the final flashing. No subcontractors. Ever. When you call (403) 603-0650, you're talking to the owner. When the crew shows up on your driveway, you're looking at the people whose name is on the company.

Calgary-Specific Experience

15+ years on Calgary roofs, through every storm

Calgary roofs face problems most of Canada doesn't. That experience shapes how Top Star designs, installs, and stands behind every project.

Chinook Freeze-Thaw

Rapid temperature swings that punish flashing, seams, and sealant. We design every roof system around them, not in spite of them.

Attic Rain

The Calgary condensation problem most contractors misdiagnose as a roof leak. We diagnose it correctly, and fix the cause, not the symptom.

Canada's Hail Capital

The June 2020 storm caused $1.4 billion in damage, Canada's costliest natural disaster. Our crew has been on Calgary roofs through every major storm since the mid-2000s.

Class 4 Hail-Resistant

We install the impact-resistant shingles we've seen actually hold up post-storm, not the ones with the best brochures.

Skylight Flashing Done Right

Velux and Columbia installs with the flashing integration most contractors get wrong on the first try.

Flat Membrane Specialists

SBS torch-on, EPDM, and TPO, in Calgary's climate, membrane choice matters more than the marketing around it.

How We Operate

Honest pricing. No upsells. Real warranties.

Top Star quotes the roof you actually need, not the one that maximizes invoice size. The principles below aren't marketing language; they're the rules Kristian uses to decide what to recommend on every quote.

Quote the roof you actually need

Not the one that maximizes invoice size. If a $5,000 repair will get you another decade out of your existing roof, Kristian will tell you.

Diagnose before you sell

If your "roof leak" is actually attic condensation, you'll get the real fix, not an unnecessary $20,000 replacement.

Document for insurance

If your hail damage qualifies for a claim, the crew documents it properly for your adjuster, photos, measurements, and detailed scope of work.

Stand behind the work

Real workmanship warranties in writing, and a real person answering the phone if you need to call about it five years from now.
