Technology
Nanotechnology vs Soy Oil — What's the Difference?
GoNano — Molecular Bond
GoNano nano-particles (5–100nm) penetrate the asphalt shingle matrix and bond at a molecular level. This creates a permanent hydrophobic barrier that:
- Restores shingle flexibility from within
- Creates a water-repelling nano-barrier
- Prevents moss and algae adhesion
- Resists UV degradation
- Survives BC freeze-thaw cycles
RoofMaxx — Soy Oil Surface Treatment
RoofMaxx applies a soy-methyl-ester oil to the shingle surface to temporarily restore flexibility. This surface treatment:
- Sits on the shingle surface (does not penetrate)
- Washes away gradually in rain
- Does not prevent moss growth
- Not available in BC or Canada
- Does not treat cedar shake or concrete
Common Questions
Is GoNano better than RoofMaxx?
For BC homeowners, GoNano is the clear choice — RoofMaxx has no certified dealers in BC or Canada. Beyond availability, GoNano uses true nanotechnology (molecular bonding) vs RoofMaxx's soy-oil surface treatment, offers moss prevention critical for BC's wet climate, and covers cedar shake roofs in addition to asphalt shingles.
Can I get RoofMaxx in BC?
As of 2026, RoofMaxx has no certified dealers in British Columbia or anywhere in Canada. Their dealer network is US-only. NanoShieldBC with GoNano nanotechnology is the equivalent BC-based solution — and in many ways technically superior.
How does GoNano nanotechnology differ from RoofMaxx's soy treatment?
RoofMaxx applies a soy-methyl-ester oil to the shingle surface to temporarily restore flexibility. GoNano nano-particles penetrate the shingle matrix and bond at a molecular level — creating a permanent hydrophobic barrier that also prevents moss adhesion. The nano-bond is more durable and provides active protection against BC's moss and moisture challenges.
What is the GoNano equivalent to RoofMaxx in Canada?
NanoShieldBC is Canada's certified GoNano applicator — the direct equivalent to RoofMaxx for Canadian homeowners. We offer the same core service (extend asphalt shingle life by 10–15 years at a fraction of replacement cost) with GoNano's superior nanotechnology and a 10-year warranty.
