Free means free

Step 1: The Free In-Person Assessment

It starts on your roof, not on a satellite photo. Sean or Shawn comes out, climbs up, and takes photos of your own shingles. The visit takes 30 to 45 minutes.

We check for granule loss, curling shingles, and how far the oils in the asphalt have dried out. UV aging and chinook freeze-thaw cycles do that to every roof in Calgary. The question is how far along yours is.

Then you get a straight answer. The sweet spot is roughly 10 to 20 years old. Widespread cracking or exposed mat means we say no, and we leave. No pressure, no kitchen-table close.

Fix before shield

Step 2: Repairs First

Almost every mid-life roof needs a few small fixes before treatment. Loose shingles from wind uplift. Small leaks. Storm-damaged spots. Spraying over problems just locks them in, so we fix them first.

That repair work is part of your quote, not an add-on. And if you only need fixes, we do standalone roof repair in Calgary too.

Step 3: Treatment Day

The crew arrives in the morning and sets up the branded tent. We mask off siding, windows and anything else that shouldn't get sprayed. Then the GoNano treatment goes on with a low-overspray process.

Most homes are done before dinner. You don't need to leave the house, and the yard gets cleaned up before we go. Curious about timing for your place? Read how long roof rejuvenation takes.

The Science, in Plain English

Asphalt shingles stay flexible because of the oils inside them. Calgary sun and freeze-thaw pull those oils out. The shingle goes brittle, sheds granules, and starts curling. That's the aging you can see from the driveway.

Most rejuvenation companies spray a bio-oil. It softens the shingle again, like lotion on dry skin. It helps, but it wears off. That's why their warranties stop at 5 years.

The GoNano treatment works the other way. It penetrates the shingle and cures into a hard silica shield.

  • Locks granules down instead of just slowing the loss
  • Water beads off instead of soaking in
  • Hardens the surface and improves impact resistance to hail and winds in lab testing
  • Holds up long enough to warrant for up to 15 years

Step 4: Your Warranty

Before we leave, your treatment gets registered with GoNano. The warranty runs up to 15 years, based on your roof's age, condition and location. It covers defects, peeling, leaks, and insurer-required replacements. And it transfers if you sell.

Most Calgary rejuvenation companies warrant 5 years. See the full warranty page for the side-by-side.
