What Your Carrier Looks For
Each carrier has different thresholds and criteria. Expand your carrier below to see exactly what triggers non-renewal — and how GoNano protective coating addresses each one.
Replace vs. Treat — The Numbers
Full Roof Replacement
$15,000–$25,000
- 3–5 day disruption to your home
- Permits, debris removal, disposal fees
- May trigger reassessment of property value
- New roof still ages from day 1
GoNano Treatment
$2,500–$4,500
- Completed in 4–6 hours, same day
- No permits required, no debris
- Extends life 10–15 years (CNETE tested)
- Includes NuRoof certification for your insurer
Average San Diego homeowner saves $12,000–$20,000 by treating instead of replacing.
