We've been restoring fences for 24 years. Now we're protecting roofs.
Same sun. Same damage. Same oil-based solution. We're excited to bring two decades of UV protection expertise to the surface that matters most — your roof.
You already understand this.
Every homeowner has watched a fence slowly go grey in the California sun. It happens so gradually you barely notice — until one day you realize it needs a coat of stain. That's all it takes to bring it back.
Before staining
A few years of California sun. The wood has gone grey and the grain is starting to show. It's not falling apart — it just needs some attention.
After staining
Oil-based stain soaks into the wood, replaces what the sun took out, and brings back the warmth. It's not new — it's just maintained. An ounce of prevention.
We've done this over a thousand times. We know exactly what UV does to organic materials.
The same thing is happening up there.
Your roof is made of asphalt — an organic binder, just like the lignin in wood. The sun breaks it down the same way. The difference? You can't see it happening from the ground.
From the ground
Looks fine. Maybe a little lighter than when it was new. You'd drive past this every day and never think twice.
Up close
The granules are thinning. The asphalt binder is slowly drying out. This roof still has years of life — but right now is the perfect time to protect it, before it becomes a bigger problem.
This is where an ounce of prevention saves you a pound of cure.
Treat it now while the shingles are still healthy — and you may never need that $15,000–$35,000 replacement.
Same sun. Same damage. Same fix.
UV radiation breaks down organic binders. In wood, it's called lignin. In asphalt, it's called bitumen. The names are different. The process is identical. And so is the solution: oil that penetrates and protects.
| Your Fence | Your Roof | |
|---|---|---|
| Material | Cedar / redwood | Asphalt shingle |
| What UV destroys | Lignin (wood binder) | Bitumen (asphalt binder) |
| What you see | Grey, dry, grain showing | Slightly faded, lighter color |
| What you don't see | Fibers weakening inside | Granules loosening, binder drying |
| The fix | Oil-based stain | GoNano (soy oil + nanosilica) |
| How it works | Oil penetrates, seals, blocks UV | Oil penetrates, seals, blocks UV |
| Visible result | Darkens the wood | Darkens the shingles |
| Cost to treat | $500 – $2,000 | $2,500 – $6,000 |
| Cost to replace | $3,000 – $8,000 | $15,000 – $35,000 |
Same concept. Same oil-based approach. Your roof is just 100 times more practical to protect.
An ounce of prevention is worth a pound of cure.
We're not here to sell you something dramatic. Roof maintenance isn't glamorous — nobody's going to post about it on Instagram. But after 24 years of protecting surfaces from the California sun, we know one thing for certain: proactive care always costs less than reactive replacement.
GoNano is preventative maintenance. It rehydrates the asphalt binder and extends your roof's useful life by 10–15 years. It doesn't heal a roof that's already too far gone — if granules are missing and fibers are showing, that roof needs replacement, and we'll tell you that honestly.
But if your roof still has life in it? We can help you keep it that way. The same way we've been keeping fences healthy since 2002 — with oil that penetrates, protects, and extends the life of the material.
What treatment looks like.
Just like oil-based stain darkens a fence as it soaks in, GoNano's soy oil and nanosilica darken shingles as they penetrate the asphalt. It's a subtle change — but it means the coating is working.
Before stain
After stain
Oil soaks in and darkens the wood. You can see it working.
Same principle on your roof. The soy oil and nanosilica soak in and darken the shingles — same visible sign that it's penetrating.
Before treatment
Faded. Drying out. Still has life — but needs attention.
After treatment
Darker. Rehydrated. Protected for another 10–15 years.

UV Expertise
We understand what the San Diego sun does to organic materials — we've been fighting it for over two decades.
Oil-Based Solutions
Oil that penetrates and protects. It's what we've always done for fences — and it's exactly what GoNano does for roofs.
Honest Assessments
If your roof needs replacement, we'll tell you. We only recommend treatment when it will genuinely help.
When we found GoNano, we didn't just take their word for it. We checked the lab reports. We read the peer-reviewed research. We looked at the UL certification. We treated our own properties first. We're proud to offer a service that can save homeowners thousands of dollars — and we don't sell anything we wouldn't put on our own roof.
We verified every claim before putting our name on it.
CNETE Lab Tested
Independent Canadian lab verified penetration depth, UV resistance, and material compatibility with asphalt shingles.
UL Certified
Underwriters Laboratories tested hail impact improvement — Class 1 shingles upgraded to Class 3 after treatment.
Peer-Reviewed Research
Nanosilica modification of asphalt documented in Scientific Reports, Construction & Building Materials, and other journals.
OSHA Biodegradable
Soy oil and nanosilica in a water-based carrier. Non-toxic, no VOCs, safe for workers and the environment.
Common Questions
Let's take a look at your roof.
We'll come out, inspect your shingles, and give you an honest assessment. If treatment makes sense, we'll show you the numbers. If your roof needs replacement instead, we'll tell you that too. No pressure — just straight talk from a team that's been doing this for 24 years.
