Roof coatings are liquid-applied systems that are brushed, rolled, or sprayed onto an existing roof. After application, they cure and harden into a continuous, seamless waterproof and protective layer that covers the entire surface. Unlike sheet roofing materials, which are installed in separate pieces that must overlap and are therefore prone to weak points at seams and joints, roof coatings create one uninterrupted membrane. This means there are no joints or laps where water can more easily penetrate. Once cured, the coating covers the whole roof in a single layer, including difficult areas such as vents, pipes, drains, and edge details. This seamless structure is especially important because many roof leaks begin at seams, fasteners, or transition points. By eliminating those weak spots, roof coatings significantly reduce common sources of water intrusion and help extend the life of the existing roof. In addition to waterproofing benefits, many roof coatings are designed to reflect sunlight and reduce heat absorption. This helps keep the building cooler, lowers indoor temperatures, and can reduce the energy needed for air conditioning. As a result, roof coatings provide both improved protection against water damage and increased energy efficiency in one application.

Roof Coating Systems We Apply

Selecting the correct coating for your roof substrate and performance requirements is critical. We assess your specific situation and recommend the coating system best matched to your roof type and goals.

Best for Flat and Low-Slope Roofs

Silicone Roof Coating

The highest-performance option for standing water environments. Silicone maintains its flexibility and waterproofing properties in prolonged contact with standing water, does not harden or crack over time, and provides outstanding UV resistance. Excellent for flat commercial roofs with drainage challenges.

Best for Metal and Shingle Surfaces

Acrylic Elastomeric Coating

Water-based elastomeric acrylic systems that stretch and recover with thermal movement, providing long-term adhesion on metal, modified bitumen, and shingle surfaces. High solar reflectance makes these systems particularly effective for reducing cooling loads. Easy maintenance and recoatability.

Best for High-Traffic Applications

Polyurethane Coating

Two-component polyurethane systems that cure to a harder surface than acrylic or silicone, making them the preferred choice for roofs subject to foot traffic, equipment maintenance activity, or abrasive environmental conditions. Available in both aromatic and aliphatic formulations.

Best for Foam and SPF Roofs

Reflective Topcoat Systems

Specialty topcoat systems designed to protect spray polyurethane foam roofing from UV degradation. These systems must be reapplied periodically to maintain the foam's UV protection, and are available in silicone, acrylic, and polyurethane bases depending on performance requirements.

Key Benefits of a Roof Coating System

🌞

Seamless Waterproofing

No laps, no seams, no joints. Liquid-applied coatings fill and seal all surface irregularities, creating a continuous waterproof barrier across the entire roof area.

⚡

Significant Energy Savings

Cool roof coatings reflect 80 to 90% of solar radiation, dramatically reducing rooftop heat gain and lowering cooling costs by 15 to 25% in warm climates.

🔄

Extends Existing Roof Life

By protecting the existing surface from UV radiation, thermal shock, and physical weathering, coatings add 10 to 20 years of additional service life to qualifying roofs.

🌎

Environmentally Responsible

Roof coatings eliminate the need for tear-off, keeping existing roofing material out of landfills. Many coatings also qualify for Energy Star certification and utility rebate programs.

📅

Recoatable at End of Life

When a coating system reaches the end of its warranty period, it can typically be recoated without removal, resetting the warranty and protective performance of the system indefinitely.

📄

Manufacturer Warranty Available

When installed by a certified applicator at specified coverage rates, manufacturer warranties of 10 to 20 years are available, providing documented coverage for both materials and performance.

Our Application Process

1

Substrate Evaluation and Candidacy Assessment

We evaluate the existing roofing surface for structural integrity, moisture content, adhesion compatibility, and overall condition to confirm it qualifies for coating and to identify any conditions that require correction before application.

2

Surface Cleaning and Preparation

The entire roof surface is pressure-washed to remove all contaminants that would prevent coating adhesion. Oxidation on metal surfaces is mechanically abraded. The surface must be completely clean and dry before primer is applied.

3

Repairs and Detail Work

All seams, cracks, penetrations, flashings, and areas of concern identified during assessment are repaired using compatible materials before the coating is applied. Coating over unrepaired failures does not solve underlying problems.

4

Primer Application

Where required by the coating manufacturer, a compatible primer is applied at the specified rate and allowed to cure before coating application begins. Primer selection is determined by both the substrate type and the coating system being used.

5

Multi-Coat System Application

The coating is applied in multiple coats at the manufacturer-specified coverage rate to achieve the required dry film thickness. We verify coverage rates during application using wet film gauges to ensure warranty compliance on every project.

6

Final Verification and Documentation

The completed coating is inspected for uniform coverage and consistent film thickness. All warranty documentation is prepared and manufacturer warranty registration is completed. A final project report with before and after documentation is provided to you.

Roof Coating FAQ

Can a roof coating stop an active leak?▼
A roof coating applied over an actively leaking roof will not solve the underlying leak. The source of any active water infiltration must be identified, the cause of the failure must be corrected, and the affected area must be properly repaired before coating is applied. Coating over an unresolved leak creates a false sense of security while the underlying problem continues to cause damage beneath the new coating surface. Our process always begins with a thorough assessment and all necessary repairs before any coating is applied, ensuring that the finished system performs as expected and the warranty remains valid.
How is a roof coating different from roof paint?▼
This is an important distinction that affects performance expectations significantly. Roof paints are thin-film products typically applied at 1 to 3 mils dry film thickness. They provide aesthetic improvement and limited UV protection but are not engineered for waterproofing performance or thermal movement accommodation. Roof coatings are engineered waterproofing systems applied at 20 to 40 mils dry film thickness or more, specifically formulated to remain flexible through thermal cycling, resist ponding water, and form a continuous waterproof membrane. The materials, application processes, warranty coverage, and performance characteristics are fundamentally different. We install roofing-grade waterproofing coating systems, not paint products, on every project.
What roof types are compatible with coating systems?▼
Roof coating systems can be applied to a wide range of existing roofing substrates when those substrates are in appropriate condition. Metal roofing, including standing seam, corrugated, and exposed fastener panels, is one of the most commonly and successfully coated surfaces. Modified bitumen and built-up roofing flat systems respond well to coating when the membrane is structurally sound and dry. EPDM and TPO single-ply membranes require specific primer systems for adhesion compatibility but can be successfully coated. Asphalt shingle roofs in good structural condition can be coated with compatible elastomeric systems. Spray polyurethane foam requires periodic recoating as part of its normal maintenance program. The key factor in any case is that the substrate must be structurally sound, free of widespread moisture infiltration, and compatible with the selected coating system.
