"Many thanks to Sokol, Aleks, Arnset and the team for repairing our flat roof in a timely manner. The guys not only did a great job installing a new rubber/membrane roof over an existing damaged roof — they were courteous and friendly throughout."
— Glen Kerr, Calgary Homeowner

Flat roof jobs don't always get the spotlight, but they get the same standard as everything else we do. Thank you, Glen.

Quick one on shingle lifespans, since it comes up a lot:

— Standard asphalt shingles: 20–25 years
— Lifetime dimensional shingles: up to 50-year warranty
— Metal roofing: 30–40 years
— EPDM (rubber): 25–30 years
— Slate, clay, cement tile: 30–60 years

The number on the warranty isn't a guarantee — proper installation and attic ventilation affect all of these just as much as the material itself. A great shingle installed badly won't hit its rated lifespan. A mid-tier shingle installed right, often will.

If you're not sure how old your current roof is or what it's rated for, that's one of the first things we check on a free estimate.

The Roof File, Episode 05.

A storm-chase repair — a homeowner who called the day after a hailstorm with visible damage and wasn't sure if it was urgent.

— Material: Trudefinition Duration STORM, Class 4 impact resistant, matched to the existing roof age and warranty
— Timeline: assessed within 24 hours, repaired within the week
— The challenge: distinguishing cosmetic granule loss from actual structural damage — not every hail mark means a full section needs replacing
— The result: targeted repair instead of an unnecessary bigger job, and a roof that's now rated for the next one

Not every hail call needs a full re-roof. Sometimes the right answer is the smaller job — same as Eli mentioned in this week's Ask the Crew.

ASK THE CREW: REPAIR OR REPLACE? 🏠🔨

One of the most common roofing questions is: “Do I really need a full replacement, or will a repair do?”

Here’s the simple way to think about it:

🔴 Multiple leaks or widespread damage? A replacement may make more sense.
🔴 One isolated issue or storm damage? A repair may be enough.

The right answer depends on the condition and extent of the damage.

No guesswork. No unnecessary upselling. Just a proper assessment and an honest recommendation.

Three months of these now, and the review bank still hasn't run thin.

"Fantastic service from start to finish! It's been 2 years since National Star replaced our roof and there have been zero issues."

If you've worked with us and haven't left a review yet — we'd genuinely love to hear from you. It's the reason posts like this exist.

The Roof File, Episode 04.

A soffit and fascia job this time — the kind of project that doesn't get talked about much but does a lot of quiet work protecting your home.

— Material: aluminum soffit and fascia, matched to existing trim color
— Timeline: 1 day
— The challenge: the old fascia board had hidden water damage behind it that wasn't visible until removal — caught and repaired before new material went up, not covered over
— The result: proper ventilation restored, no rot hiding behind a fresh coat of paint

This is the kind of thing a rushed job skips. We don't.

Two months of these now, and it never gets old reading them.

"Fantastic service from start to finish! It's been 2 years since National Star replaced our roof and there have been zero issues... I haven't even found a nail or any other roofing remnant in my yard."
— Rachel Appleby, Calgary Homeowner

Zero issues, two years out, yard left cleaner than they found it. That's the standard — not the exception.

Back to Sokol for this one — a project he's brought up a few times as one of the more satisfying jobs of the year.

A full re-roof where the original deck needed more attention than expected. Instead of rushing past it, the crew slowed down, addressed it properly, and still finished on schedule.

"The easy thing is to cover a problem and move on. The right thing is to fix it before it's covered. That's the difference between a roof that lasts and one that doesn't."
— Sokol

Two months in, this is still the throughline: the work you don't see is where the real quality shows up.
