2-PART SYSTEM

A flat roof treatment that does more than just seal

Most flat roof coatings are thin films that degrade over time or trap moisture beneath the surface. Liqua-Roof Flat is engineered differently. It’s a high-performance, two-part resurfacing system combining our proprietary resin blend base with a durable, resin enveloped, granule top layer — delivering a protective barrier that looks, performs, and will even outlast a brand-new roof.

HOW IT WORKS

A customized system for flat roofs

1. White resin basecoat

Our proprietary white resin blend is spray-applied to form a seamless, breathable membrane that adheres tightly to the roof surface. This first layer bridges small cracks and creates a bright, reflective foundation that boosts energy efficiency and roof performance from day one.

Key Benefits:
- Strong adhesion to asphalt-based substrates
- Reflective white finish for thermal performance
- Breathable film allows vapour to escape
- Bridges minor imperfections and surface wear

2. Clear resin & granule topcoat

A second layer of our proprietary clear resin and granules is applied. The granules are fully enveloped by the resin, creating a durable outer shell that protects against UV, hail, abrasion, and foot traffic.

Key Benefits:
- Granules encapsulated in a resin for a reinforced, impact-resistant layer
- Enhanced texture for walkability and visual appeal
- Long-term reflectivity with minimal chalking or yellowing
- Forms a protective barrier that mimics the profile of a new roof

Why choose Liqua-Roof over silicone roof coatings?

Silicone roof coatings are popular but come with trade-offs: they’re slippery, non-breathable, and prone to discolouration. Liqua-Roof solves those issues — and adds performance advantages.

Is Liqua-Roof Flat better than silicone roof coatings?

Yes — unlike traditional silicone, Liqua-Roof offers breathability, granule reinforcement, and curb appeal. It performs better over time without yellowing or peeling.

How long does Liqua-Roof Flat last?

Our system is designed for long-term durability and can significantly extend the life of your roof when properly installed. A new layer of protective granules are essentially glued in place providing an armour like barrier to protect the roof.

Is Liqua-Roof Flat slippery like silicone coatings?

No. Our granules add texture for better foot traction, making it safer for roofs with walkability needs.

INNOVATIVE FORMULATION

We don't just coat your roof, we armour it

Standard coatings seal. Liqua-Roof rebuilds. Our 2-layer system—reinforced with solar-reflective granules—delivers strength and protection that generic silicone can’t match.

Granule-Reinforced Protection

Granules create a physical, weather-resistant armour that protects the roof against UV, hail, and foot traffic.  

True Film Build

Most coatings dry down to 20–30 mils — our granule layer builds beyond that, creating a shield, not just a skin.  

Breathable Barrier

Our flat roof system lets moisture escape instead of trapping it like silicone coatings.

Same-Day Application

Both layers are applied on the same day using our custom spray equipment for fast, seamless results.

Reflective & Customizable Finish

White base and granules improve reflectivity and come in other colour options if desired.

Versatile Substrate Compatibility

Designed specifically for aging asphalt shingles and low-slope roofing systems.
