Spray-applied polyurea RV roofs

Stop resealing your RV roof. Seal it for good.

A certified applicator sprays one seamless polyurea membrane over your existing roof, about 120 mils thick, wrapped over the edges and around every vent. No laps. No sealant beads left to crack.

The problem

Water always finds the seam.

Factory RV roofs are sheets of rubber, TPO, fiberglass or aluminum, held together by sealant around every vent, skylight, antenna and edge. Sun and road flex dry that sealant out. It cracks, and water gets into the roof deck and walls long before you see a stain on the ceiling.

Sealant cracks

Lap sealant shrinks and checks under UV. Most owners end up re-caulking the same joints every season.

Membranes wear out

Rubber roofs chalk, thin out and tear. Branches, hail and foot traffic finish the job.

Leaks hide in the walls

By the time a soft spot or ceiling stain shows up, the decking and framing underneath are already wet.

The fix

Polyurea turns your roof into one piece.

Polyurea is sprayed on as a liquid and sets in seconds to minutes into a tough, flexible membrane that bonds to the roof underneath. Instead of patching seams, you get rid of them.

  • SeamlessOne continuous membrane, front cap to rear cap. Nothing to re-caulk.
  • Wraps the weak spotsSprayed over the roof edges and up around vents, AC bases and skylights, where leaks start.
  • Built thickAbout 120 mils of basecoat. Thin 30 to 40 mil coats don't hold up on a roof.
  • Back on the road fastFast-tack topcoats are tack-free in about an hour, so most rigs finish the same day.

How it works

From leaky to leak-proof in four steps.

Two applicators spraying polyurea on an RV roof inside a shop
  1. 01

    Inspect and quote

    Your applicator looks over the roof, notes soft spots, solar, vents and anything that needs repair, then gives you a written quote.

  2. 02

    Prep

    Failing sealant and loose material come off, the surface is cleaned and abraded, and everything that shouldn't be coated is masked.

  3. 03

    Spray

    The polyurea basecoat goes on at about 120 mils, wrapping over the edges and sealing around every penetration in the same pass.

  4. 04

    Topcoat and go

    A UV-stable topcoat goes over the basecoat, or a single aliphatic coat does both jobs. Then you drive home.

Roof systems

Two proven ways to do it right.

Both are ArmorThane systems sprayed by certified applicators. Your installer will recommend the one that fits your roof, your climate and how you travel.

Two-step system

SureGrip basecoat + ArmorDeck Topcoat

A tough polyurea basecoat builds the thickness and grip, then ArmorDeck Topcoat locks in UV protection and color. ArmorDeck Topcoat MAX is tack-free in about an hour, so the whole roof can be finished in a day.

  • Thick, textured basecoat
  • UV-stable topcoat on top
  • Same-day finish with MAX
Single-coat system

ArmorFlex UV

An aliphatic polyurea that holds up in direct sun on its own, so it's sprayed as a complete roof with no topcoat over it. One product, one pass of chemistry, full build.

  • Aliphatic, UV-stable by itself
  • No topcoat required
  • Sprayed to full 120-mil build

Clean lines. No seams.

Polyurea rounds over the roof edges, climbs up around fixtures and leaves a uniform, walkable surface from end to end.

FAQ

Good questions, straight answers.

Still wondering about something? Ask us directly.

How long does a polyurea RV roof take?

Most roofs are prepped, sprayed and topcoated in about a day, depending on the rig's size, the condition of the existing roof and the weather. Fast-tack topcoats like ArmorDeck Topcoat MAX are tack-free in roughly an hour, which is what makes a same-day finish realistic.

Can it go over my existing rubber, TPO, fiberglass or aluminum roof?

In most cases, yes. The applicator inspects the roof first. Loose, failing or soft areas are repaired, old sealant that is coming apart is removed, and the surface is cleaned and prepped so the polyurea bonds to it.

How thick is the coating?

RV roofs are sprayed to about 120 mils of basecoat, which is roughly an eighth of an inch. Thin 30 to 40 mil coats are not enough for a roof that lives in the sun and flexes down the highway.

What happens around vents, AC units and skylights?

Fixtures are masked and the membrane is sprayed up around their bases, so the joints where most RV roof leaks start are sealed in the same pass as the rest of the roof.

Can I walk on it?

Yes. Cured polyurea is a tough, walkable surface, and textured finishes add grip. Use the same care you would on any RV roof: good ladder, dry surface, no stepping on vents or skylights.

How much does it cost?

It depends on the length of the rig, the condition of the roof, how much prep is needed and which system you choose, so we do not publish a flat price. Tell us about your RV and you will get a real quote from a local applicator.

Who stands behind the work?

Each certified installer warranties their own work, and the coating systems come from ArmorThane, which has manufactured polyurea since 1989. Ask your applicator to walk you through their warranty when you get your quote.
