Expandothane Roof Coating Guide: Commercial Roof Restoration

RSP Painting is an approved certified installer of Expandothane roofing systems across the entire East Coast. This guide explains what Expandothane is, how it works, and why it is a high-performance choice for commercial building owners and facility managers.

What Is Expandothane Roof Coating?

Expandothane is a spray-applied, two-component hybrid polyurea roof coating system designed for commercial, industrial, and residential flat and metal roofs.

Unlike standard roof paints or basic coatings that spray on as a thin layer, Expandothane contains special micro-blowing agents. When applied using specialized high-pressure spray equipment, the coating expands up to 5 to 7 times its original liquid volume.

As it expands, it fills in deep cracks, gaps, rusted seams, open joints, and damaged areas. It cures in seconds to form a thick, seamless, quarter-inch-thick waterproof barrier over the entire roof surface.

Key Benefits of Expandothane for Property Owners

• Eliminates Roof Tear-Offs: Expandothane goes on top of existing, structurally sound roofs. This saves thousands of dollars in labor and keeps tons of trash out of landfills.

• No Seams, No Leaks: Roofs typically fail at the seams, fasteners, and flashing areas. Expandothane forms a 100% monolithic (one-piece) rubberized topcoat across the entire roof with no seams or screw holes.

• Extreme Weather and Hail Protection: Expandothane creates a thick, flexible membrane, and acts as a shock absorber. It provides severe defense and holds a Level four hail resistance rating.

• Handles Ponding Water: A lot of roof coatings break down, peel, or fail when water ponds on them.Expandothane stands up to standing and ponding water without delaminating or wearing down.

• Cures in Seconds: The rapid chemical reaction allows the coating to set almost instantly. This minimizes downtime, eliminates the risk of rain washing the wet coating away, and keeps business operating as usual.

• Energy Savings: Finished with a reflective UV topcoat, Expandothane drops roof surface temperatures by 30°F to 50°F. This reduces air conditioning costs during hot summer months.

   

How RSP Painting Installs Expandothane

As an approved certified installer, RSP Painting follows strict manufacturer application protocols to ensure complete system performance and full warranty coverage.

1. Surface Inspection & Preparation: We inspect the roof deck, repair wet or soft insulation, power-wash all surface dirt, greases, and chalking, and ensure the substrate is dry and clean.

    

2. Priming (If Required): Depending on the substrate (such as aged single-ply or heavily oxidized metal), a dedicated primer is applied to maximize adhesion.

3. Expandothane High-Pressure Spray Application: Using high-pressure, heated plural-component spray equipment, our certified crews apply the Expandothane hybrid polyurea base coat. The material expands to fill voids, seal fasteners, self-flash around roof penetrations, and cure into a dense 1/4-inch waterproof membrane.

4. Protective Topcoat Application: A weather- and UV-resistant aliphatic topcoat (or 100% silicone topcoat) is applied. This locks in permanent UV protection, prevents yellowing or degradation, and adds high reflectivity.

    

Substrates Expandothane Can Be Applied To

Expandothane bonds directly to most commercial and industrial roofing substrates:

• Metal Roofing (Standing Seam, Corrugated, R-Panel)

• Modified Bitumen & Smooth/Granulated Rolled Asphalt

• Built-Up Roofs (BUR / Tar & Gravel)

• Single-Ply Membranes (TPO, EPDM, PVC)

• Spray Polyurethane Foam

• Concrete Roof Decks & Structural Walls

Frequently Asked Questions (FAQ)

What makes Expandothane different from standard elastomeric roof paint?

Standard elastomeric paint goes on as a thin coat and only covers the surface. Expandothane is an expanding polyurea hybrid. It expands up to 7x its volume, filling holes, cracks, and open seams from the inside out before hardening into a thick 1/4-inch protective shell.

Why is hiring an approved certified installer like RSP Painting important?

Expandothane requires high-pressure, heated equipment and precise 1:1 chemical mixing. As an approved certified installer, RSP Painting has the specialized machinery, trained crews, and factory certification required to apply the system correctly and secure full manufacturer warranties.

Can Expandothane be installed while our business is open?

Yes. Because Expandothane is 100% VOC-free, low odor, and applied quickly without loud roof tear-off machinery, work proceeds while your business operates as normal.

How long does an Expandothane system last?

When properly applied and protected with a UV topcoat, Expandothane systems can carry warranty options up to 15 to 20 years. The system is renewable: when the topcoat wears down years later, it can simply be washed and topcoated again without tearing off the roof membrane.

Does Expandothane stop leaks around roof HVAC units and pipes?

Yes. Because it expands during application, Expandothane expands around pipes, HVAC curbs, drains, and roof penetrations, sealing difficult areas where traditional roofing membranes often fail.

Is Expandothane safe for the environment?

Yes. It has zero VOCs (harmful emissions) and eliminates the need to tear off existing roofing materials, keeping commercial waste out of local landfills.
