What Is Nanosilica, and Why Is It Used in Roof Rejuvenation?
“Nanotechnology” sounds highly technical.
But for homeowners, the idea is simpler than it sounds.
NanoTech Exteriors uses GoNano technology designed to work at an extremely small scale within qualifying roofing materials.
Instead of thinking about it as a thick layer placed on top of the shingles, think about it as a material treatment designed to interact with the roof itself.
The goal is not to paint the roof.
The goal is to help preserve aging asphalt shingles that still have useful service life.
What Does “Nano” Mean?
A nanometre is one billionth of a metre.
At that scale, engineered particles can interact with materials differently than conventional surface products.
For roofing, nanoscale technology can be used as part of a treatment system designed to support:
- Material flexibility
- Water resistance
- Resistance to weather-related stress
- Long-term preservation
That makes nanotechnology relevant to asphalt shingles because aging happens within the material—not only on the visible surface.
Why Do Asphalt Shingles Need Preservation?
Ontario roofs experience:
- UV exposure
- Summer heat
- Rain
- Snow
- Wind
- Freeze-thaw cycles
Over time, asphalt shingles can gradually become:
- Dry
- Stiff
- Brittle
- More vulnerable to cracking
The roof may still be structurally sound while the material itself is clearly aging.
That is the stage where preservation may be worth evaluating.
Is Nanosilica the Same as a Roof Coating?
No.
NanoTech does not position GoNano as a conventional roof coating.
A traditional coating typically creates a film over a surface.
Roof rejuvenation is designed to work with the existing asphalt roofing material itself.
That distinction matters because NanoTech’s goal is not:
cover the aging
but:
address the aging material while the roof is still worth preserving.
Does Nanotechnology Fix Structural Problems?
No.
Nanotechnology cannot replace:
- Rotten decking
- Missing shingles
- Failed flashing
- Structural sagging
- Major leaks
Those issues require proper roofing repair or replacement.
That is why NanoTech inspects the roof before recommending rejuvenation.
Why Condition Comes Before Technology
An advanced product still needs the right application.
A roof should first be evaluated for:
- Shingle condition
- Decking
- Leaks
- Flashing
- Physical damage
- Overall structural integrity
Only then can NanoTech determine whether preservation makes sense.
The Technology May Be Advanced. The Decision Should Still Be Practical.
If your asphalt roof is aging but still structurally sound, NanoTech Exteriors can assess whether nanotechnology-based rejuvenation is an appropriate alternative to premature replacement.
