Question 1

What is GoNano roof rejuvenation?

Accepted Answer

GoNano roof rejuvenation is a nanotechnology-based treatment that uses 40-60nm silica particles to penetrate and restore asphalt shingle roofs at the molecular level. It restores elasticity, blocks UV degradation, and seals micro-cracks, extending your roof's life by 10-15 years.

Question 2

How much does roof rejuvenation cost compared to replacement?

Accepted Answer

GoNano roof rejuvenation typically costs 75-85% less than a full roof replacement. For a typical San Diego home, treatment costs $2,500-$4,500 compared to $15,000-$25,000+ for replacement.

Question 3

Is the science behind GoNano proven?

Accepted Answer

Yes. Nanosilica modification of asphalt bitumen is documented in peer-reviewed journals including Scientific Reports (Nature Publishing), the International Journal of Pavement Research, and Construction & Building Materials. GoNano products are UL tested and CNETE certified.

Question 4

What areas does Roof Care Pros serve?

Accepted Answer

Roof Care Pros serves all of San Diego County and the Eastern Sierra region including Mammoth Lakes, June Lake, Bishop, and surrounding communities.

Question 5

Will GoNano treatment void my roof warranty?

Accepted Answer

No. GoNano treatment is OSHA biodegradable and does not void manufacturer warranties. It is a surface-applied treatment that works with your existing shingles.

Question 6

Can GoNano treatment help me keep my homeowner's insurance?

Accepted Answer

Yes. GoNano treatment upgrades your roof's hail impact rating from Class 1 to Class 3 or 4 (UL-tested), which many insurers require to issue or renew policies in California. Several of our San Diego customers have had coverage reinstated after treatment.

Question 7

How long does GoNano treatment last?

Accepted Answer

GoNano treatment comes with a 15-year warranty and is designed to extend your roof's life by 10-15 years. The nanosilica particles form covalent-like bonds with the asphalt binder that are durable and long-lasting.

Question 8

How do I get a free roof inspection?

Accepted Answer

Call or text us at (760) 914-4037, or fill out the contact form at roofcarepros.com/contact. We serve San Diego County and the Eastern Sierra, and we respond within 2 business hours.

Question 9

Why are California insurance companies cancelling homeowner policies?

Accepted Answer

Over 400,000 California homeowner policies have been cancelled since 2021. Major carriers like State Farm, Allstate, and Farmers are withdrawing due to wildfire losses exceeding $40 billion. Roof condition is now the #1 factor in non-renewal decisions, with insurers using drone inspections and AI to assess roof age and deterioration.

Question 10

What happens if I get dropped to the California FAIR Plan?

Accepted Answer

The FAIR Plan is California's insurer of last resort and typically costs 2-3x more than standard coverage while offering less protection. It can also make your home harder to sell. A $3,000 GoNano treatment that keeps you on standard coverage saves $2,000-$5,000 per year in premium differences.

Question 11

Can GoNano treatment reverse an insurance non-renewal notice?

Accepted Answer

Yes. Many homeowners have successfully reversed non-renewal decisions by submitting GoNano's certification package to their insurer. You typically have 30-75 days from a non-renewal notice to demonstrate the issue has been addressed. We provide a complete documentation package including UL test certifications, before/after photos, and template letters.
