You see the fence aging. You don't see the shingle.
Same sun. Same damage. Same solution. We've been protecting surfaces from California UV for 24 years. Here's how a fence company became a roofing company — and why it makes more sense than you'd think.
The same process
Wood Fence
UV breaks down lignin — the organic polymer that holds wood fibers together. The surface greys, grain raises, cracks form. You see this happen. You know it needs stain.
Asphalt Shingle
UV breaks down bitumen — the organic binder that holds shingle aggregate together. Granules shed, edges curl, material cracks. You don't see this happen. But it does.
Different material. Same enemy. Same solution category.
Oil penetrates and protects wood. Oil penetrates and protects asphalt.
The same fix
Stain restores a fence
Oil-based stain penetrates the wood grain, replaces lost oils, blocks UV, and restores the rich color. The wood goes from grey and brittle to dark and flexible. You can see the difference in a single pass.
GoNano restores a roof
GoNano's nanosilica formula penetrates the asphalt binder, replaces lost oils, blocks UV, and restores flexibility. The shingles darken back toward their original color — the same visible sign that the material is being restored.
| Fence Stain | GoNano | |
|---|---|---|
| Material | Wood (cedar, redwood) | Asphalt shingle |
| Binder destroyed by UV | Lignin | Bitumen |
| What it does | Penetrates, seals, blocks UV | Penetrates, seals, blocks UV |
| Visible result | Darkens wood, restores color | Darkens shingles, restores color |
| Life extension | 5–8 years per application | 10–15 years per treatment |
| Alternative | Replace the fence ($3K–$8K) | Replace the roof ($15K–$35K) |
Real results
The Darkening Effect
Just like stain restores the rich color of wood, GoNano re-saturates the asphalt binder. The shingles darken — a visible sign the oil is working.
Before
Faded, light grey, UV-degraded shingles
After
Darker, uniform, re-saturated shingles

Surfaces restored
Tom Sawyer Fence Painting
Founded 2002. Thousands of fences, decks, and pergolas restored across California. We learned UV damage by fighting it every day for two decades.
Roof Care Pros
Launched 2024. Same team, same UV expertise, new surface. GoNano certified dealer — because we vetted the science the way we vet every product we use.
The science
We didn't just take their word for it
Before we put our name on GoNano, we checked the research the same way we check every product we use on a customer's property.
CNETE Lab Tested
Independent Canadian lab verified penetration depth, UV resistance, and material compatibility.
UL Certified
Underwriters Laboratories tested hail impact improvement — Class 1 shingles upgraded to Class 3/4.
Peer-Reviewed Research
Nanosilica modification of asphalt bitumen documented in Scientific Reports, Construction & Building Materials, and others.
OSHA Biodegradable
Water-based, non-toxic, safe for workers and the environment. No VOCs, no harsh chemicals.
