What nanotechnology means here
Asphalt and concrete are both porous. Water, salt and UV work their way into those openings, and that is where the damage starts.
Nanotechnology means working at a particle size small enough to move through those openings instead of stopping at the surface. The pores fill, the surface stops soaking up water, and nothing is added on top that can peel away later.

Nano treatment
Where it sits
On the surface, as a layer

How long it holds
Redealt with every few seasons
Applied once, no film to flake
Moisture
Can trap water underneath
Surface stays breathable
Finish
Changes how the surface looks
Keeps the original look
Nanosilica, briefly
The treatments are built on nanosilica: an inorganic material with a high density of silica that fills the pores it reaches and stiffens the surface from the inside.
Because it works chemically rather than as a covering, the result is a surface that still looks like what it is, and still lets moisture vapour move out of the material.
Technical detail
The specifics, in plain language
- How deep the treatment goes
- Depth depends on the porosity of the surface: asphalt shingles and concrete each take the treatment in differently. The intent is the same in every case: fill the openings water would otherwise use.
- Why climate changes the conversation, not the product
- Freeze-thaw, high UV, salt air and heavy rain wear a surface down in different ways. The climate of your area is part of the assessment, because it tells us what your surface is up against. It does not change which treatment fits: your roof’s condition score does.
- How the technology is tested
- The products are put through industry impact, wind and fire testing, and the references we can point to are listed on the certifications page. Those ratings describe material testing. They are not a promise about your roof.
