COMMERCIAL FLAT ROOF RESURFACING

The flat roof resurfacing system that builds up protection

Liqua-Roof Flat forms a thick, seamless protective layer that delivers unmatched performance, at less than half the cost of conventional flat roofing systems.

Liqua-Roof Flat is not a conventional rolled or seamed flat roofing system/membrane.

It is a two-part, flat roof resurfacing system that forms a seamless, monolithic membrane reinforced with real roof granules, offering durable protection without seams, layers, or repeated re-application.

OVERVIEW

Flat roofing systems are strong, but not seamless  

Flat roofing systems protect flat and low-slope roofs using structural layers topped with a waterproof membrane, typically sheet rolls like TPO, EPDM, PVC, or modified bitumen, or a liquid-applied roofing system. However, these membranes create seams that can become weak points over time.
PAINPOINTS
Seams are prone to lifting and can cause water-infiltration
Performance and durability vary widely by system type
Expensive installation  
Leaves a coated/painted appearance
OVERVIEW

A hybrid flat roofing resurfacing system

Liqua-Roof Flat isn’t a traditional sheet or rolled flat roofing system or a standard liquid-applied coating. Instead, it blends elements of both — the seamless application of a liquid system with the durability boost of a granule-reinforced surface.

SYSTEM PROPERTIES

Flat roof resurfacing, thoughtfully engineered for your property

We considered every detail—from seams to water protection to reflectivity—and built it into one seamless, monolithic, granule-reinforced solution.

 Granule-Reinforced Reflective Surface
Direct-Bond Retrofit Application

Two layers, one stronger flat roof system

Liqua-Roof Flat combines a high-adhesion white basecoat with a reinforced granulated topcoat to deliver a cooler, stronger, more durable flat roof surface.

White resin basecoat

- Strong adhesion to asphalt-based substrates

- Reflective white finish improves thermal performance

- Breathable film allows vapor to escape

- Bridges minor imperfections and surface wear
 

Proprietary resin & granule blend topcoat

- Granules fully encapsulated in resin for reinforced, impact-resistance

- Textured surface enhances walkability

- Mimics the profile and appearance of a new roof

No seams, no vulnerabilites

Because Liqua-Roof Flat isn’t rolled, seamed, or stitched together, it cures into a single, monolithic membrane. No joints, no lifting edges, and no water pathways. Just seamless protection backed by a reinforced granule finish built to outlast traditional flat roofing systems.

A rock solid topcoat for superior performance

Liqua-Roof Flat’s topcoat is reinforced with real roofing granules, forming a thick, weather-resistant layer that stands up to UV rays, hail, and foot traffic. With more than twice the thickness of typical coatings, this granule-reinforced surface delivers long-lasting protection against even the harshest weather conditions.

No costly tear-offs

Traditional flat roofing systems require removing the existing roof, increasing time, costs to homeowners, and the environmental impact. Liqua-Roof Flat bonds directly to your existing surface. No tear-off, no removal, and no exposing the building means a faster, more cost-effective solution.

Two-Part Liquid-Applied System

Liqua-Roof Flat combines a high-adhesion white basecoat with a reinforced granulated topcoat to deliver a cooler, stronger, more durable flat roof surface.

White Resin Basecoat

The white resin basecoat bonds aggressively to asphalt, improves thermal performance, allows vapor to escape, and smooths minor surface imperfections.

Proprietary resin & granule blend topcoat

Granules are fully encapsulated in resin to deliver reinforced, impact-resistant protection, while the textured surface improves walkability and replicates the look of a brand-new roof.

HOW IT WORKS

A customized system for flat roofs

A two-component system designed to protect, reinforce, and extend the life of your flat roof.

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 vapor 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 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

when to choose

Liqua-Roof Flat is the superior choice for flat roofs

Faster, more durable, and no tear-off required, our system outperforms traditional solutions from the start.

Conventional Flat Roofing System

CHOOSE WHEN

Your flat roof deck, insulation, or structure is damaged or requires rebuilding.
Traditional flat roofing systems are necessary when a full tear-off is required, either due to structural issues, multiple existing layers, or building code mandates. These systems allow for a complete rebuild and redesign before applying a new roofing membrane.
Flat Roof Resurfacing

CHOOSE WHEN

Your flat roof is starting to show signs of wear, with minor repairs needed, but the deck and structure are still sound.
Liqua-Roof Flat is designed to reverse signs of flat roof degradation by creating a seamless, granule-reinforced membrane that strengthens and protects your roof. It prevents small issues from turning into a full replacement, delivering long-lasting performance without the disruption of a tear-off.

HIGH-PERFORMANCE BENEFITS

Resurface & rebuild your flat roof's defense

Liqua-Roof Flat gives your roof the benefits of a replacement, with the speed and ease of a liquid-applied system.

Granule-based protection

Granules create a physical, weather-resistant armor 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.

Quick, seamless installation

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

Reflective & colored finish

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

Engineered for aging roofs

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