Concrete Tile Roof Preservation

Industrial-Grade Polyaspartic Protection

for Long-Term Performance

Concrete tile roofs are already one of the longest-lasting roofing systems available. When properly preserved, they can outperform nearly every other residential roofing material on the market.

At The Great Canadian Roof Doctor Inc., we preserve qualifying concrete tile roofs using a plural-component, industrial-grade polyaspartic system—a product originally engineered as the final protective coating for offshore oil rigs, bridges, and tunnels, where failure is not an option.

This is not a decorative coating.
It is a high-performance preservation system designed for longevity, durability, and control.

Why Preserve a Concrete Tile Roof?

Concrete tile roofs are designed to last decades—but exposure to UV, moisture, organic growth, and surface erosion can gradually increase maintenance requirements and shorten effective performance.

Preservation focuses on:

Protecting the tile surface from ongoing deterioration
Reducing water absorption and surface erosion
Limiting moss and organic growth
Stabilizing colour and finish
Reducing long-term maintenance costs

Preserving a tile roof before damage occurs helps keep the system intact, predictable, and serviceable for the long term.

The Polyaspartic Advantage

The polyaspartic system we use is a plural-component, industrial-grade product, meaning it is chemically cured on site to form an extremely durable protective layer.

This type of product was originally designed for:

Offshore oil and gas platforms
Bridges and transportation infrastructure
Tunnels and high-exposure environments

These are applications where coatings must:

Bond aggressively
Cure quickly and evenly
Resist UV, moisture, and abrasion
Perform for decades, not years

That same durability makes it exceptionally well-suited for concrete tile preservation.

Why We Brush — Never Spray

Polyaspartic coatings are permanent once cured. Any overspray would bond immediately and could only be removed mechanically, risking damage to surrounding surfaces.

For this reason:

We only brush-apply this product
Application is slow, deliberate, and controlled
Every tile receives intentional coverage
There is zero risk of overspray on windows, siding, landscaping, or adjacent properties

This method eliminates application shortcuts and ensures the system is installed correctly and responsibly.

Our Inspection-First Process

Not every concrete tile roof is a candidate for preservation.

Before recommending this system, we perform a full roof inspection, evaluating:

Tile condition and integrity
Cracks, spalls, or breakage
Fasteners and attachment systems
Underlayment age and performance (where visible)
Flashings, valleys, and penetrations
Drainage and water flow

If the roof is not a suitable candidate, preservation will not be recommended.

Proper Preparation Is Essential

Before application:

The roof is professionally cleaned using tile-safe methods
Moss, algae, and contaminants are removed
Damaged or broken tiles are repaired or replaced
The surface is allowed to fully dry

Polyaspartic coatings are only as effective as the surface they bond to. Preparation is non-negotiable.

Long-Term Benefits of Concrete Tile Preservation

When applied to a qualifying roof, polyaspartic tile preservation can:

Protect tiles from further surface erosion
Reduce moisture absorption
Slow organic growth
Stabilize colour and appearance
Dramatically reduce ongoing maintenance
Preserve the integrity of an already long-lasting roofing system

For many homeowners, this means avoiding repeated maintenance cycles and potentially never needing to re-roof, provided the system continues to be inspected and maintained responsibly.
