Commercial Roof Coatings & Restoration, at a glance

A coating is a fluid-applied membrane rolled or sprayed over a roof that still has a sound deck and dry insulation. Done on the right roof it buys ten years and avoids a tear-off. Done on a wet roof it seals the water in and wastes the money. John Beal Roofing tests the roof first and says which one it is. Call (314) 429-6000.

The Short Version

Whether This System Fits Your Building

Best suited to

roofs with a sound, dry substrate and mostly surface-level aging — not roofs with saturated insulation.

Service life

10 to 20 years depending on the coating and the mil thickness applied.

What to watch

Moisture in the insulation. if the scan shows wet areas, they get cut out and replaced before anything gets coated.

Installation

Where These Roofs Actually Fail

Membrane failures are almost never in the middle of the sheet. They start at the details — the curb flashing, the pipe boot, the wall termination, the drain.

That is why we spend the time on the parts nobody photographs. A field seam takes minutes; a properly rebuilt curb takes an afternoon and it is what decides whether the roof makes twenty years.

We also register the manufacturer warranty on your building, so the coverage exists in writing under your address rather than in a folder somewhere.

Common Questions

How long will this roof last in St. Louis?

10 to 20 years depending on the coating and the mil thickness applied. Our freeze-thaw cycles and summer heat are hard on any membrane, so the install details and a twice-yearly inspection matter as much as the material.

Can we recover over the existing roof instead of tearing off?

Sometimes. If the substrate is dry and the deck is sound, a recover saves real money. If a moisture scan shows wet insulation, tearing off is the only honest answer.

Do you install this system yourselves?

Yes. Our own crews do the work, and we hold manufacturer certifications for the systems we install, which is what makes the full system warranty available.

What does a repair on this system cost versus replacement?

A localized repair is a fraction of a replacement, and on a roof with remaining life it is the right call. We will tell you which one your roof is — with photos.

How disruptive is the installation?

Low-slope work happens on the roof, not inside the building. We coordinate hot work, odor and noise windows with the tenants or residents before we mobilize.
