How Long Does Roof Rejuvenation Last?

GoNano NuRoof™ treatment comes with a 10-year warranty and is designed to extend your roof's serviceable life by 10–15 years. Here's what that means in practice.

10 Years
Manufacturer Warranty

GoNano backs every treatment with a full 10-year warranty.

10–15 Years
Life Extension

Most treated roofs gain 10–15 additional years of serviceable life.

25+ Years
Total Roof Life

A roof treated at year 10–12 typically reaches 25+ years total.

What Affects How Long It Lasts?

Shingle Age at Treatment

Roofs treated at 8–14 years old get the most benefit. The earlier the treatment, the more life extension is possible. Roofs treated at 16–20 years still benefit significantly but may gain 8–12 years rather than 15.

Shingle Condition

Shingles with good granule retention and no structural damage respond best to treatment. Our free inspection assesses this before any commitment.

Climate Exposure

BC's wet climate is actually ideal for GoNano — the treatment's hydrophobic properties are most valuable in high-rainfall environments. UV exposure in summer is the primary factor that depletes the treatment over time.

Moss Management

Keeping moss under control after treatment extends its effectiveness. GoNano's hydrophobic surface significantly slows moss regrowth, but periodic maintenance helps maximize longevity.
