What's Covered

Most roof rejuvenation warranties in Calgary run 5 years. Ours runs up to 15, based on your roof's age, condition and location. Here's what it covers:

  • Defects in the treatment
  • Peeling
  • Leaks
  • Insurer-required replacements

That last line matters in this city. Insurers look hard at roof age on renewals. If your insurer requires a replacement, our warranty covers it. We also give you documentation to show them.

The warranty transfers when you sell, too. A transferable warranty turns an aging roof from an inspection objection into a selling feature.

All of it sits on top of the treatment itself, our GoNano roof rejuvenation.

Age, condition, location

How the Term Is Set

Not every roof gets the full 15 years, and we won't pretend otherwise. Three things set your term.

Age

How old the roof is

The sweet spot is roughly 10 to 20 years old. Younger, healthier shingles earn longer terms.

Shape

Condition today

Granule loss, curling shingles and brittle spots shorten what we can honestly promise.

Spot

Where it sits

Calgary sits in a hail corridor, and exposure differs street to street. Trees, wind and sun all count.

The honest block

What's Not Covered

A warranty you can't trust is worse than no warranty. So here's the straight version.

Hail damage is an insurance matter. No product makes a roof hail-proof. The cured shield hardens the shingle surface and improves impact resistance to hail and winds in lab testing. But storm damage claims go through your home insurer, not this warranty. Our documentation helps with those claims.

Roofs that are too far gone don't get treated. Widespread cracking or exposed mat means the roof doesn't qualify. We tell you that at the assessment and walk away. No treatment, no warranty, no wasted money.

Your shingle manufacturer's warranty is a separate thing. Most roofs we treat are past the useful window of that coverage anyway. Read does rejuvenation void my shingle warranty for the straight answer.
