Drey Roofing coats metal and single-ply flat roofs across the Omaha area using Sherwin-Williams and KARNAK coating systems — restoring a qualifying roof instead of tearing it off.
A full roof replacement is expensive and disruptive to your business — and if your roof’s structure is still sound, it may not be necessary yet. That’s exactly the kind of situation Drey Roofing helps Omaha businesses solve every day.
A professionally applied roof coating seals your existing roof, reflects heat, and adds years of protection — at a fraction of the cost of a full replacement. Drey Roofing applies trusted Sherwin-Williams and Karnak coating systems on both metal roofs and single-ply flat roofs, giving Omaha businesses a durable way to protect their roof investment without starting from scratch.

Coatings for both roof types
Coating systems we install
Applied correctly over a qualifying roof, a coating isn’t a cosmetic patch — it’s a functional layer that changes how the roof performs.
Renews an aging membrane or metal panel that still has structural life left in it.
Fills hairline cracks and lap seams into a single continuous, monolithic surface.
Reflective coatings shed sun exposure and shrug off Midwest rain, hail, and freeze-thaw cycles.
Reinforces the spots that fail first - laps, flashing, pipe boots, and curbs.
Buys years of service life on a roof before replacement becomes necessary.
In the right situation, a fraction of the cost and disruption of a full tear-off.
We focus our coating work on the two roof types where the technique holds up best in commercial buildings across the metro.
Metal panels chalk, fade, and rust at seams and fasteners long before the structure underneath gives out. A coating renews the surface and reseals the panel laps.
Flat membrane roofs shrink, seams open, and ponding water wears through the surface over time. A coating renews the membrane and reinforces seams and penetrations.
Every coating recommendation starts with a hands-on inspection, not a sales pitch. We check:
These are three different jobs, and an honest contractor doesn’t sell you the same answer every time. Here’s how we tell them apart.
For isolated damage on a roof that’s otherwise sound — a storm-damaged section, a single failed seam, a leak around one penetration.
Best when: damage is localized and the rest of the roof is healthy.
For a roof with a sound membrane or panel and no major moisture intrusion, but one that’s aging, chalking, or losing its seal across the whole surface.
Best when: the substrate still has life left, and an inspection confirms it.
For a roof with widespread wet insulation, structural damage, or a membrane too deteriorated to seal reliably. No coating fixes what’s underneath.
Best when: restoration would only make a bigger problem.
