Why Moisture Matters More Than Age

In this image, the left side has been untreated whereas the right side has been protected with GoNano. The overnight frost and morning dew penetrated and soaked the untreated side. The right side being protected, keeps moisture out. Eastern Passage, NS, October 2024.

The Primary Cause of Roof Degradation

While UV exposure contributes to aging, water absorption is the dominant driver of premature roof failure.

When asphalt shingles absorb moisture, they become vulnerable to:

• Freeze–thaw expansion and cracking

• Granule loss and surface erosion

• Accelerated oxidation and brittleness

• Reduced structural integrity

Reducing moisture uptake is one of the most effective ways to slow roof deterioration.

Hydrophobic Performance (Water Repellency)

How Water Is Prevented From Entering the Shingle

Hydrophobicity is measured using water contact angle testing. Higher contact angles indicate stronger water repellency.

Independent laboratory testing on GoNano treated shingles shows:

• Significantly increased water contact angles

• Water beading and runoff instead of absorption

• Reduced liquid water ingress into porous substrates

Real‑world result: shingles stay drier after rain, snow, and ice exposure.

Note* Hydrophobic surface behavior is most visible on dry substrates. During sustained rainfall, water may form a continuous film on the shingle surface. While visible beading may be reduced, the nano treatment remains chemically bonded within the material, limiting capillary water uptake and accelerating drying once rainfall subsides.

On the treated side, hydrophobic surface chemistry causes water to bead and shed more readily, reducing surface wetting and limiting standing water. This behavior helps decrease moisture contact time with the asphalt following rainfall.

Breathability & Vapor Permeability

Repelling Water Without Trapping Moisture

A roofing system must allow water vapor to escape while preventing liquid water from entering.

Third‑party testing confirms that nano‑treated materials retain vapor permeability, meaning:

• Moisture from inside the roof assembly can escape

• Attic ventilation performance is not compromised

• Risk of blistering, rot, and mold is reduced

This balance is critical for long‑term roof health.

Freeze–Thaw Resistance

Designed for Cold‑Climate Performance

When absorbed water freezes, it expands by approximately 9%. Over thousands of freeze–thaw cycles, this expansion causes micro‑fractures, cracking, and granule loss.

By reducing water absorption, nano‑treated shingles experience:

• Lower internal ice formation

• Reduced freeze‑thaw stress

• Improved durability in cold climates

This is particularly relevant in Atlantic Canada.

Two views of a GoNano-treated asphalt shingle roof during snow, frost, and ice conditions. As snow and frost begin to melt, hydrophobic surface chemistry causes meltwater to bead and shed rather than uniformly wetting the shingle surface. This reduced surface wetting limits moisture contact time during freeze–thaw cycles.

UV Exposure & Oxidation

Slowing the Aging Process

Nano treatments are not paints or pigments, but they help slow moisture‑driven oxidation that accelerates UV damage.

Accelerated aging tests indicate improved retention of:

• Shingle flexibility

• Surface integrity

• Resistance to embrittlement

Reducing moisture reduces the rate at which UV damage compounds over time.

This photo shows aged shingles not protected with GoNano. The UV exposure has lead to increased granule loss and drying, leaving the shingle edged curled and exposed to the elements.

Structural & Environmental Safety

Designed to Work With Your Roof System

Nano roof treatments:

• Are non‑film‑forming

• Do not add measurable weight

• Do not alter shingle appearance

• Do not change fire ratings

• Do not interfere with ventilation systems

The treatment integrates into the existing roofing material rather than overriding it.

• GoNano: Although the initial cost may be higher, the long-term savings from reduced maintenance and extended surface life make it a cost-effective solution.

• Traditional Sealants: Lower initial costs but higher long-term expenses due to frequent maintenance and reapplication needs.

The result: a unified barrier against stains caused by environmental factors.

Nova Spray's utilization of GoNano’s revolutionary technology represents a significant advancement in surface sealants. Traditional sealants merely coat surfaces, often filling spaces with oil and providing a temporary barrier. In contrast, Nova Spray’s treatments fundamentally alter the molecular structure of materials, particularly asphalt shingles. Upon application, a chemical reaction initiates within each shingle, creating new S1 particles that bind both organic and inorganic components. These particles link shingle granules together from within, forming a unified, durable barrier against environmental stressors. This inside-out approach not only enhances protection but also extends the lifespan of your roof, saving you money on maintenance and replacements over time.
