Don't Replace Your Mountain Roof. Restore It.

Eastern Sierra homeowners are saving $12,000–$25,000 by treating their roofs with proven nano-technology instead of replacing them. Mountain replacement costs are 25–35% higher — but treatment costs the same.

Simple Process

Three Steps to a Longer-Lasting Roof

No demolition. No dumpsters. No weeks of construction noise. Most treatments are completed in a single visit.

1

Free Inspection

We inspect your roof's condition, take photos, and determine which GoNano product is the right fit. You get a detailed condition report — no obligation.

30–45 minutes
2

Professional Treatment

Our certified technicians apply GoNano’s nanosilica formula using professional spray equipment. The treatment penetrates deep into the asphalt binder.

2–4 hours

Why Mountain Roofs Fail Faster

5 Alpine Threats Destroying Your Roof

Eastern Sierra roofs face conditions that accelerate aging 2–3x faster than lowland roofs. Here's what's happening to your shingles right now.

300+inches/year

300-400" Annual Snowfall

Mammoth's massive snow loads crush aging shingles. GoNano restores flexibility so shingles bend instead of crack under weight.

50°F+daily swing

Extreme Freeze-Thaw Cycles

Daily temperature swings from -10°F to 40°F cause constant expansion and contraction. Nano-particles maintain elasticity through extremes.

40%more UV

Intense UV at 8,000+ Feet

At altitude, UV radiation is 25-40% stronger. GoNano's silica particles reflect UV — the #1 cause of shingle degradation.

#1roof killer

Ice Dam Formation

Melting snow refreezes at eaves, forcing water under shingles. GoNano's hydrophobic barrier seals micro-cracks against moisture intrusion.

60+mph gusts

Mountain Wind Exposure

Sierra winds accelerate granule loss from shingles. Nano-bonding locks granules in place, preventing the erosion that triggers insurance issues.

5month window

Short Construction Season

Roof replacement in Mammoth is only possible June–October. GoNano treatment takes just 1 day and can be applied in a wider weather window.

The Real Math

Treatment vs. Replacement: Mountain Pricing

Mountain replacement costs are 25–35% higher than lowland areas due to remote location, steep roof pitches, and a 5-month construction season. Treatment costs the same everywhere.

Average cost (2,000 sq ft)$18,000–$32,000

The Science

How Nanotechnology Restores Your Mountain Roof

Your asphalt shingles are made with petroleum-based binders that dry out over time. At altitude, UV radiation, freeze-thaw cycles, and moisture accelerate this aging 2–3x faster than lowland roofs. As the binder hardens, granules loosen, cracks form, and your roof becomes vulnerable.

GoNano's nanosilica particles (40–60 nanometers) are small enough to penetrate deep into the asphalt binder — far deeper than any traditional sealant. Once inside, they form permanent molecular bonds that restore flexibility, reflect UV radiation, and create a hydrophobic barrier against moisture.

Deep Molecular Penetration

40–60nm particles bond within the asphalt binder itself — not just a surface coating

Freeze-Thaw Resilience

Maintains shingle flexibility through extreme daily temperature cycles

UV Reflection at Altitude

Silica reflects the intense UV radiation at 8,000+ feet elevation

Ice Dam Defense

Hydrophobic barrier seals micro-cracks against moisture intrusion

Homeowner Experiences

What Eastern Sierra Homeowners Say

“After two brutal winters, our roofer said we needed a full replacement at $28,000. GoNano treatment cost us $4,200 and our roof looks better than it has in years. The inspector was impressed.”

Sarah M.

Mammoth Lakes

“We were skeptical about any roof treatment, but the science convinced us. One day, no mess, and our 14-year-old roof got a new lease on life. The freeze-thaw protection alone is worth it at this altitude.”

David & Karen L.

June Lake

“As a property manager with 6 buildings, the portfolio savings were substantial. We treated all roofs in one week during the summer window. No tenant disruption, no dumpsters, no permits needed.”

Is This Legit?

An honest, transparent review of every major GoNano claim — with verdicts based on peer-reviewed research and third-party testing.

GoNano science comparison

The short answer: The underlying science is real and peer-reviewed. Nanosilica modification of asphalt bitumen is documented across dozens of studies in reputable journals, including Scientific Reports (Nature Publishing), the International Journal of Pavement Research, and Construction & Building Materials. GoNano is not snake oil. However, the company is ~5 years old — meaning the 15-year warranty claim cannot be independently verified by real-world outcomes yet. Evaluate accordingly.

Mountain-specific note: Freeze-thaw cycles and UV at altitude are the two biggest killers of Eastern Sierra roofs. GoNano's flexibility restoration and UV reflection mechanisms are scientifically the most relevant benefits for your climate.
